Description

[0001] MULTI-FUNCTIONAL CONTROLLED RELEASE TABLET COMPOSITIONS WITH ENHANCED STABILITY AND POTENCY AND ENVIRONMENTAL IMPACT TRACKING

[0002] FIELD

[0003] The present disclosure relates to personal, home, office, workplace and fabric care products. Particularly, the present disclosure relates to multi-functional controlled-release tablet compositions for consumer products.

[0004] DEFINITION

[0005] As used in the present disclosure, the following term is generally intended to have the meaning as set forth below, except to the extent that the context in which it is used, indicates otherwise.

[0006] Molar substitution: The term “molar substitution” refers to the average number of substituent groups such as hydroxyalkyl group and the like, attached to each repeating unit in a polymer. It is a key parameter that influences properties such as solubility, stability, pharmacological action and the like of the modified polymer.

[0007] BACKGROUND

[0008] The background information herein below relates to the present disclosure but is not necessarily prior art.

[0009] Traditional liquid formats used in personal care, home care, workplace and fabric care products often fail to deliver consistent performance, as the active ingredients tend to degrade through oxidation and hydrolysis when exposed to water during manufacturing. These actives further degrade during the distribution stage. These actives still further degrade during the shelf-time at point of sale (POS), be it offline or online distribution centers.

[0010] Finally, when they reach the consumer, these actives further degrade in the consumer’s shelf over the period of use. The role of actives in personal, home, office, workplace and fabric care is paramount as it directly relates to the performance of products, thereby directly relating to the consumer satisfaction index. If the product performs better and quicker, the consumer satisfaction index shoots up. The traditional product lifecycle approach involves adding water at the manufacturing stage of the product which leads to inefficiencies multiplying at each stage of the product lifecycle ultimately adding significantly to carbon emissions and climate crisis.

[0011] Effervescent tablet technologies, which combine solid acids and bases to generate carbon dioxide and rapidly dissolve into a use-solution, have been used as a method for delivering cleaning products. These tablets offer advantages such as reducing the need to ship water, enabling convenient, on-demand preparation and the like. However, the existing effervescent products fail to deliver the desired levels of cleaning performance, multi-functionality, sensory experience and safety. Known effervescent formulations fail to protect sensitive or volatile active ingredients from interaction or degradation during storage. The viability of conventionally known probiotic effervescent tablets are preserved through reduced compaction force. However, these probiotic effervescent tablets cannot maintain high residual activity due to degradation caused by pre-hydrolysis.

[0012] Further, conventional acid-base effervescent blends tend to neutralize each other, yielding only mild to moderate pH, which is insufficient for removal of heavy scale.

[0013] Furthermore, conventional tablet formulations are mainly designed for foam pumps and fine- mist sprayers, and often rely on thickeners or conventional viscosity modifiers, which can clog spray nozzles and foaming mechanisms, making refilling across various consumer devices or dispensers difficult. To address this issue, some formulations adopted extremely low-viscosity solutions or completely eliminated them to prevent clogging. However, these thin solutions often drip from surfaces, resulting in poor deposition, limited coverage, and subpar sensory performance in personal care and homecare applications.

[0014] Therefore, there is felt a need to provide a tablet composition that can mitigate the drawbacks mentioned hereinabove or at least provides an alternative solution.

[0015] OBJECTS

[0028] DETAILED DESCRIPTION

[0029] The present disclosure relates to personal, home, office, workplace and fabric care products. Particularly, the present disclosure relates to multi-functional controlled-release tablet compositions for consumer products.

[0030] Embodiments, of the present disclosure, will now be described herein. Embodiments are provided so as to thoroughly and fully convey the scope of the present disclosure to the person skilled in the art. Numerous details are set forth, relating to specific components, and methods, to provide a complete understanding of embodiments of the present disclosure. It will be apparent to the person skilled in the art that the details provided in the embodiments should not be construed to limit the scope of the present disclosure.

[0033] The terms first, second, third, etc., should not be construed to limit the scope of the present disclosure as the aforementioned terms may be only used to distinguish one element, component, region, layer or section from another component, region, layer or section. Terms such as first, second, third etc., when used herein do not imply a specific sequence or order unless clearly suggested by the present disclosure.

[0034] The active ingredients of conventional liquid products for personal, home, office, workplace, and fabric care degrade due to oxidation and hydrolysis when water is introduced during manufacturing. This degradation continues throughout the distribution cycle, storage, and consumer use, reducing product effectiveness and consumer satisfaction. Adding water early in the product lifecycle also leads to inefficiencies that increase carbon emissions and environmental impact.

[0035] Effervescent tablet technology, which uses solid acids and bases to generate carbon dioxide and dissolve into a use-solution on demand, offers benefits such as reduced water shipping and convenient preparation. However, conventional effervescent products often lack adequate cleaning performance, multi-functionality, and safety. They also fail to protect sensitive or volatile actives during storage. The viability of conventionally known probiotic effervescent tablets are preserved through reduced compaction force. However, these probiotic effervescent tablets cannot maintain high residual activity due to degradation caused by prehydrolysis.

[0036] Further, conventional effervescent tablets designed for use with foam pumps and fine-mist sprayers contain thickeners that clog nozzles thereby making the refilling process more difficult.

[0082] In an embodiment of the present disclosure, the composition comprises a carrier molecule.

[0083] The carrier molecules used in the composition of the present disclosure forms inclusion complexes with volatile and unstable active agents, fragrances and the like ensuring zero pump clogging. Further, the carrier molecules have a high water solubility ensuring a transparent and clear solution.

[0084] In an embodiment of the present disclosure, the carrier molecule is selected from the group consisting of maltodextrin, amylodextrin, a,P-dextrin, cyclodextrin, zeolite, talc, starch and their derivatives.

[0085] In an embodiment of the present disclosure, the carrier molecule is characterized by: a molecular weight in the range of 1.2 kDa to 1.5 kDa; and a molar substitution in the range of 3.0 to 4.5. In an exemplary embodiment of the present disclosure, the carrier molecule is hydroxypropyl-P-cyclodextrin (HPpCD) having a molecular weight in the range of 1.2 kDa to 1.5 kDa and a molar substitution in the range of 3 to 4.5 (7*MS).

[0086] Molar substitution (MS) indicates the average number of hydroxypropyl groups attached to each glucose unit in HPpCD, which has 7 glucose units arranged in a ring. An MS of 3 to 4.5 means that, on average, each of the 7 glucose units in the P-cyclodextrin ring has 3 to 4.5 hydroxypropyl groups attached resulting in a total of 21 to 31.5 hydroxypropyl groups per HPpCD molecule (7 units x 3.0-4.5 MS). The hydroxypropyl-P-cyclodextrin used in the composition of the present disclosure has a high degree of substitution of about 21 to 32 hydroxypropyl groups per molecule resulting in significantly enhanced aqueous solubility compared to the native PCD. Thus, the hydroxypropyl-P-cyclodextrin used in the present disclosure enables enhanced complex forming property facilitating efficient encapsulation and stabilization of different active agents, thereby improving their bioavailability and formulation performance.

[0087] Further, the HPpCD having the specific molecular weight and molar substitution as mentioned above is capable of functioning across different foam pumps and fine-mist finger sprayers without clogging or blocking the pump for a minimum of 500 actuations.

[0088] In an embodiment of the present disclosure, the HPpCD is capable of functioning as a carrier for sensitive ingredients such as vitamins, fragrances, essential oils, probiotics, enzymes, antimicrobials, peptides and the like.

[0089] In an embodiment of the present disclosure, biological active agents are stabilized through pre-tableting complexation / encapsulation with HPpCD. The encapsulation reduces water activity (aw < 0.20), protects hydrophobic regions, and preserves steric spacing, thereby enhancing the stability, potency, and shelf-life of biological active agents such as enzymes, probiotics and the like, ensuring improved functional performance upon use.

[0090] The HPpCD are ring-shaped molecules made from sugar units having a hydrophobic (waterrepelling) interior and a hydrophilic (water-attracting) exterior allowing it to trap the sensitive ingredients inside the ring to form an inclusion complex. The formation of the inclusion complex stabilizes the ingredients by shielding them from oxygen, light, and moisture, thereby preventing degradation of the active agents / ingredients before the product is used and helps to maintain the full potency of the actives till the actual use. The formation of the inclusion complex thus helps in overcoming the stability limitation present in conventional aqueous products. Further, fragrance oils encapsulated within the HPpCD form clear, stable aqueous solutions upon dissolution of the composition, preventing oily droplets that commonly clog foaming pumps and fine-mist sprayers, ensuring clog-free dispensing throughout the product usage.

[0091] In an embodiment of the present disclosure, the hydroxypropyl-P-cyclodextrin (HPpCD) is capable of co-encapsulating fragrance oils together with non-volatile ethoxylated alcohols, such as C16-C18 EO25 and functional equivalents, to form a dual-guest inclusion complex. This complex facilitates differential release kinetics, enabling a unique ternary system that provides a rapid initial release of top-note fragrance components, followed by a sustained release of base notes, thereby enhancing long-lasting sensory perception. The non-volatile ethoxylated alcohol weakens the volatility of the top notes of fragrance (K_app J, ~40 %), giving a fast initial burst. Less-volatile base notes remain strongly bound (K_app ~ 105M '). supplying a slow “tail”. Outside the cavity, the EO-chain lowers interfacial tension to 2.5 mN m1at 0.05 % w / v, keeping 5-6 wt % perfume dissolved as a single, clear phase. As the nonvolatile ethoxylated alcohol is largely hidden in the complex, it does not foam and the resulting solution remains clear, single-phase, and exhibits minimal foam generation, making it particularly suitable for fine-mist and non-foaming applications. In an embodiment of the present disclosure, the non-volatile ethoxylated alcohol has a hydrophile-lipophile balance (HLB) in the range of 14 to 16.

[0092] The carrier molecule in the composition of the present disclosure forms complexes with the ingredients by encapsulating the ingredients and thus enhances the ingredient distribution, increases liquid-holding capacity, optimized, delayed release upon contact with water and improves overall efficiency of the composition when dissolved in water. The carrier molecule surrounds / incorporates the ingredients within its structure leading to enhanced stability, solubility, and controlled release of the ingredients when the composition is dissolved in water.

Blending the liquid and volatile components with the carrier molecules results in the formation of inclusion complexes which ensures controlled release, improved stability, and protection of the active agents / other ingredients from degradation or evaporation.

[0160] In an embodiment of the present disclosure, the pre-treated mixture is then blended with the remaining ingredients to obtain the master blend.

[0161] The so-obtained master blend is optionally granulated by using a binder at a temperature in the range of 15 °C to 25 °C and at a relative humidity in the range of 15 % to 25

[0162] %, followed by drying and milling to obtain a milled blend.

[0163] In an embodiment of the present disclosure, the granulation is wet granulation.

[0164] In an embodiment of the present disclosure, the binder is selected from the group consisting of croscarmellose sodium, sodium starch glycolate, low-substituted hydroxypropyl cellulose, polyvinylpyrrolidone, hydroxypropyl cellulose, xanthan gum, guar gum and polyethylene glycol.

[0165] In an embodiment of the present disclosure, the granulation is carried out using high-shear mixers, ultra-sonic mixers or fluid bed granulators.

[0175] In an embodiment of the present disclosure, the master blend or the milled blend or the lubricated mixture is compressed into tablets using a tablet press.

[0176] In an embodiment of the present disclosure, the tablet compression is multi-stage and multilayer.

[0177] During compression, the compression force, speed, and tablet thickness are monitored in realtime, to ensure consistent tablet quality.

[0178] In an embodiment of the present disclosure, the composition is in a shape selected from the group consisting of flat faced, circle, oval, triangle, square, rectangle, pentagon, hexagon, heptagon, octagon, cylindrical, hollow cylinder, convex, diamond and star.

[0179] The tablet shapes are designed to minimize contact between stacked tablets to reduce flavor cross-contamination, by limiting surface contact. Shapes like domed, beveled-edge, or ringshaped tablets also influence dissolution rate by altering the surface area exposed to water.

[0180] The so obtained controlled release, tablet composition is optionally coated at a temperature in the range of 15 °C to 25 °C and at a relative humidity in the range of 15 % to 25 % to obtain a coated controlled release, tablet composition.

[0183] Coating of the controlled-release, tablet composition of the present disclosure is performed not only to facilitate manufacturing but also to serve as a protective barrier, helping to prevent accidental user contact with products containing extremely low or high pH.

[0184] The controlled release, tablet composition of the present disclosure is subjected to quality control testing prior to packaging and market release. In an embodiment of the present disclosure, the packaging is carried out at a temperature in the range of 15 °C to 25 °C and at a relative humidity in the range of 15 % to 25 %.

[0185] The tablets are packed using packaging technologies that protect against moisture, light, and mechanical damage. In an embodiment of the present disclosure, the packaging comprises an in-built desiccant system to control moisture levels inside the package.

[0186] In an embodiment of the present disclosure, the package is made of a material selected from the group consisting of paper sachets with moisture barrier, polyethylene (PE), high-density polyethylene (HDPE), low-density polyethylene (LDPE), aluminium, glass and stainless steel. The packaging material is compatible with the Proof-of-Green technology for end-to- end impact mapping and circularity implementation.

Unlike conventional compositions, the compositions of the present disclosure remain stable till they are dissolved in water, ensuring greater effectiveness and longer- lasting performance of the active agents.

[0188] The composition of the present disclosure is dissolved in water to obtain freshly activated products such as serums, perfumes, sunscreens, toners, or other personal care and hygiene applications with enhanced efficacy and user satisfaction compared to conventional preformulated products.

[0189] The composition of the present disclosure is capable of generating pre-foam for manual dishwashing, toilet cleaning and the like, eliminating the need for manual lathering. The composition of the present disclosure rinses faster than conventional gels, powders, and bars, reduces soap residue on dishes leading to enhanced cleaning efficiency and water saving.

[0190] The composition enables direct use on dry hands or skin for applications such as hand wash, body wash and the like by eliminating the need for pre-wetting and thus significantly reduces water usage, specifically during the pre-rinsing stage.

[0191] The composition of the present disclosure on dissolution produces lump-free solutions, dispersions or emulsions, ensuring smooth and clog free dispensing and proper product function due the controlled pre-processing steps used during the manufacturing of the composition.

[0192] The process of the present disclosure uses concentrated liquid fragrances or liquid active agents which form complexes with the carrier molecule. The concentrated fragrance or active agent is encapsulated within the carrier molecule leading to enhanced liquid-holding capacity, and improved ingredient distribution, particularly in fragrance-heavy or active-heavy compositions, resulting in clearer and more uniform solutions or emulsions upon tablet dissolution. The controlled pre-processing steps used during the manufacturing of the composition of the present disclosure produces a lump-free solution, dispersion or emulsion on dissolution ensuring smooth and clog free dispensing and proper product function.

[0193] The present disclosure provides a system, Proof-of-Green, for measuring and displaying environmental savings from using the disclosed compositions in personal, home, and fabric care. The system includes digital tracking using blockchain or QR codes, calculation of savings in plastic, paper, and fuel, a user interface for displaying savings and ensuring transparency, tracking of product circularity in FMCG, counterfeit prevention, and supply chain monitoring.

[0194] The composition of the present disclosure is in tablet form that offers compactness and suitability for multi-packs of the same product / application. This reduces the single-use plastic and paper by over 90% and delivers more than 20 times logistical efficiency, all trackable in real time via Proof-of-Green technology, enabling economically viable circularity in FMCG products.

[0195] A key aspect of the present disclosure is the superior dispensing compatibility of the controlled-release tablet, achieved by the use of hydroxypropyl-P-cyclodextrin (carrier molecule) and the specialized low-viscosity xanthan gum (rheology modifier), individually or in combination. Unlike conventional formulations that often clog foam pumps or mist sprayers due to viscosity modifiers or carrier molecules, the combination of the carrier molecule and the rheology modifier of the present disclosure ensures a clear, stable solution and consistent, clog -free dispensing, even after more than 500 actuations. On the other hand, conventional cyclodextrins and gums, especially at higher concentrations, caused significant clogging in under 10 actuations. This optimized combination hydroxypropyl-P-cyclodextrin (carrier molecule) and the specialized low-viscosity xanthan gum (rheology modifier) used in the composition of the present disclosure enhances product reliability, usability, and consumer satisfaction.

[0201] The controlled-release, tablet composition was prepared at a controlled condition of 20 °C and a relative humidity (RH) of 20 %.

[0202] Initially, all the ingredients were checked and sorted prior to starting the preparation process. If, liquid, volatile / unstable ingredients were used in the composition, they were blended with the carrier molecule(s) to obtain a pre-treated mixture. The pre-treated mixture was subjected to drying, if required, using one or a combination of spray drying, vacuum drying, freeze drying. Drying was carried at a temperature below the room temperature (-40 °C to 30 °C) to ensure that volatile ingredients were not degraded. The pre-treated mixture was then blended with other ingredients to obtain the master blend. If, liquid, non-volatile ingredients were used in the composition, they were blended with the carrier molecule(s) to obtain a pretreated mixture. The pre-treated mixture was subjected to drying, if required, using one or a combination of spray drying, and vacuum drying. Drying was carried at a temperature between 30 °C to 100 °C. The pre-treated mixture was then blended with other ingredients to obtain the master blend. The ingredients were blended at 20 °C and 20 % RH to obtain a master blend.

[0203] The master blend was optionally granulated at 20 °C and 20 % RH, followed by optional drying and milling to obtain a milled blend.

[0204] The master blend or the milled blend was then optionally lubricated at 20 °C and 20 % RH using a lubricant to obtain a lubricated mixture.

[0205] The master blend or the milled blend or the lubricated mixture was then compressed by exerting a force in the range of 5 tons to 25 tons at 20 °C and 20 % RH to obtain the controlled release, tablet composition of the present disclosure.

[0206] The specific amounts of the ingredients used for the preparation of the controlled release, tablet compositions of the present disclosure are provided in Experiments 1 to 17.

[0207] Experiment 1: Preparation of the controlled- release, tablet composition for use as an auto air freshener in accordance with the present disclosure

[0208] A composition for use as an air freshener was prepared using the ingredients as disclosed in Table- 1.

[0209] The controlled-release, tablet composition was prepared at a controlled condition of 20 °C and a relative humidity (RH) of 20 %.

[0210] Pre-treatment step:

[0211] A liquid blend was first prepared using HPBCD + C16-C18 Fatty alcohol + a portion (1 g) of the concentrated lemon grass fragrance + mandarin fragrance (2: 1) in a ratio of 1: 1:0.5 in 5 portions of water. This blend was then subjected to freeze drying to obtain a pretreated mixture in the form of freeze dried powder.

[0212] The freeze drying was carried out at a temperature of -40 °C to 30 °C to ensure that the volatile ingredients (fragrances) were not degraded.

[0213] Preparing the master blend:

[0214] The pre-treated mixture was then blended with the other ingredients in an octagonal blender to obtain a master blend. The remaining portion of the concentrated fragrance (lemon grass fragrance + mandarin fragrance (2: 1)) was added during the blending step.

[0215] The master blend was then compressed using a 12-ton tablet compression setup at 20 °C and 20 % RH to obtain the controlled release, tablet composition of the present disclosure.

[0216] 16.05 g of the composition (tablet) was dissolved in 300 ml of water to obtain an aerosol-free auto air freshener having a pH of 7. The tablet composition encapsulates cetyl stearyl alcohol and the fragrance within HPpCD in the form of a dual-guest encapsulation complex, enhancing fragrance stability and enabling controlled release. Upon dissolution, it generates an aerosol-free, CCE-driven mist that disperses fragrance efficiently, ensuring smooth, clog- free use in fine-mist sprayers, providing a clear improvement over conventional air fresheners.

[0217] Comparative evaluation of the air freshener of the present disclosure with marketed air freshener

[0218] The performance of the air freshener obtained in Experiment 1 of the present disclosure comprising HPpCD (carrier molecule) was compared with a marketed product devoid of HPpCD. The results obtained are summarized in Table- la.

[0219] The air freshener tablet (16.05 g) of the present disclosure and the marketed tablet were individually dissolved in 300 ml of water in standard mist sprayer bottles. All the solutions were tested for the following parameters and the results obtained are summarized in Table- la: dispensing efficiency was tested by actuating fine-mist spray dispensers continuously for 500 times to simulate extended consumer usage; fragrance bloom and aroma retention qualitatively was assessed in standard 200 sq. ft. test room, measured hourly by sensory evaluation panel over 24 hours; fragrance release assessed qualitatively by sensory perception of top notes (immediate) and base notes (over extended hours); and safety assessed by noting absence of solvents (verified through MSDS).

[0220] The air freshener of the present disclosure (Experiment 1) comprising HPpCD demonstrated improved fragrance delivery performance, with enhanced initial perception of the top notes, significantly higher fragrance retention specifically base notes, and increased fragrance load compared to the marketed product devoid of HPpCD. HPpCD enabled fragrance release in stages, wherein immediate top-note were released, followed by sustained base-note diffusion, resulting in overall sensory perception. The air freshener of the present disclosure exhibited minimal phase separation and uniform fragrance distribution, indicating strong physical stability and functional reliability. Further, the air freshener of the present disclosure is entirely water-based and solvent-free, mitigating risks associated with conventional solventbased air fresheners.

[0221] Experiment 2: Preparation of the controlled-release, tablet composition for use as a sprayable serum in accordance with the present disclosure

[0222] A composition for use as a fragrance-free sprayable full body serum was prepared using the ingredients as disclosed in Table-2.

[0223] All the ingredients after checking and sorting were directly compressed using a 7-ton tablet compression setup at 20 °C and 20 % RH to obtain the controlled release, tablet composition of the present disclosure.

[0224] 19.15 g of the composition (tablet) was dissolved in 50 ml of water to obtain vitamin C full body serum having a pH of 5.1. The obtained serum was used for application in ultra-fine mist spray dispenser.

[0225] The HPpCD in the composition of the present disclosure stabilized the active agent (vitamin C and niacinamide) and prevented oxidation and hydrolysis resulting in extended potency. The low viscosity xanthan gum ensured smooth, clog-free dispensing through fine foam pumps.

[0226] Comparative evaluation of the vitamin C serum of the present disclosure with a marketed vitamin C serum.

[0227] Consumer-perceived performance of a marketed vitamin C liquid serum (6 months postmanufacture) and a freshly constituted vitamin C tablet serum in accordance with the present disclosure were assessed for a one-month period. The tablet composition (containing derivatized Vitamin C) obtained in Experiment 2 was dissolved in 50 ml of potable water to obtain the vitamin C serum in accordance with the present disclosure. The tablet composition was dissolved in water immediately prior to first use. The marketed product containing derivatized Vitamin C liquid serum used was stored under standard conditions.

[0228] For the study, 10 female participants in the age group of 25 to 45 years and having different skin types were randomly selected. Each participant applied the composition of the present disclosure on one half of the face, and the marketed vitamin C product on the other half of the face. The study was carried out for a duration of 30 days. The observations were recorded on a weekly basis. The participants were instructed to dissolve one tablet (19.15 g) in 50 ml potable water till a clear solution was obtained post complete dissolution of the tablet. This solution was used for the duration of the study by each participant. Both, the serum prepared from the composition of the present disclosure and the marketed vitamin C serum with same concentration of vitamin C were directly applied on each half of the face by the participants. All the participants were instructed to apply 4 drops (~0.2 ml) of the serums evenly to cleansed facial skin, once daily (evening), following standardized skincare routines. All participants used both the products each time on each half of the face. The serums were evaluated on the following parameters and the observations are summarized in Table -2a:

[0229] • skin brightness: perceived increase in skin radiance and brightness.

[0230] • skin texture: smoothness, evenness, and refined appearance of skin texture.

[0231] • reduction in dark spots: visibility reduction of dark spots or pigmentation marks. • skin firmness: improvement in perceived skin elasticity and tightness.

[0232] • product stability: change in serum appearance, color, and texture over usage

[0233] • period.

[0234] • overall satisfaction: aggregate user satisfaction based on overall experience.

[0235] It is seen from Table-2a that the vitamin C serum of the present disclosure was capable of consistently providing a noticeable improvement in skin brightness and texture, reduction in dark spots, improved in skin firmness and skin elasticity, compared to the marketed serum. Further, the vitamin C serum of the present disclosure remained clear indicating no detectable oxidation during the study period. Whereas, the marketed vitamin C serum showed yellowing due to degradation of vitamin C over the 6 months of storage. It is well known that vitamin C is susceptible to oxidative degradation in aqueous solutions resulting in loss in potency. On the other hand, the tablet-based composition of the present disclosure maintained vitamin C in a stable dry form till use. The vitamin C present in the tablet composition of the present disclosure was activated upon dissolution in water, resulting in enhanced performance as compared to the marketed vitamin C serum.

[0236] Experiment 3: Preparation of the controlled-release, tablet composition for use as a disinfecting floor cleaner in accordance with the present disclosure A composition for use as a disinfecting floor cleaner was prepared using the ingredients as disclosed in Table-3.

[0237] Experiment 3 was carried out following a similar process as provided in Experiment 2.

[0238] 19.4 g of the composition (tablet) was dissolved in 10000 ml (10 L) of water to obtain a floor cleaner having a pH of 8.

[0239] The tablet composition encapsulates cetyl stearyl alcohol and the fragrance within HPpCD in the form of a dual-guest encapsulation complex, enhancing fragrance stability and enabling controlled release. The surfactants (cetyl stearyl alcohol and sodium alpha olefin sulfonate) used in the composition provided the cleaning action in the floor cleaner.

[0240] Comparative evaluation of the floor cleaner of the present disclosure with marketed floor cleaners

[0241] The performance of the floor cleaner of the present disclosure comprising HPpCD (carrier molecule) was compared with marketed products devoid of HPpCD. The results obtained are summarized in Table-3a.

[0242] The floor cleaner tablet of the present disclosure and the marketed tablet were individually dissolved in 10000 ml (10 L) of water in regular floor cleaning buckets. All the solutions were tested for the following parameters and the results obtained are summarized in Table-3a:

[0243] - visually, olfactorily and cleansing of pre-existing oil spills (each solution was applied evenly across standardised 100 sq. ft. tiled flooring);

[0244] - fragrance bloom immediately upon application;

[0245] - odour control assessed by sensory panel in test room post-cleaning;

[0246] - absence of harmful phenols (confirmed through MSDS review); and

[0247] - cleaning efficiency assessed visually for residue, cleanliness, and shine post-drying.

[0248] The solutions were classified “Pass” only if: o clear rapid dissolution achieved without sediment; o fragrance bloom and odour control maintained without phenolic odour; and o visually evident cleaning performance on the spill using a touch feel squeaky clean sensorial evaluation and shine without residue.

[0249] It is seen from Table-3a that the HPpCD-based floor cleaner tablet of the present disclosure demonstrated enhanced cleaning efficacy, fragrance delivery, and user safety as compared to the conventional compositions. The composition of the present disclosure dissolved completely within 3 minutes without any visible sediment, providing a quick and convenient solution.

[0250] Further, the composition of the present disclosure delivered strong fragrance bloom and long- lasting odour control without the use of harmful phenols. It effectively removed oil spills, leaving surfaces clean and residue-free. Thus, the composition of the present disclosure is a safer and more effective alternative to conventional phenol-based and tablet floor cleaners.

[0251] A composition for use as a foam spray toilet cleaner was prepared using the ingredients as disclosed in Table-4.

[0252] Experiment 4 was carried out following a similar process as provided in Experiment 2.

[0253] 17.35 g of the composition (tablet) was dissolved in 300 ml of water to obtain a foam spray toilet cleaner having a pH of 1.5. The surfactants (cetyl stearyl alcohol and sodium alpha olefin sulfonate) used in the composition provided the cleaning action in the toilet cleaner. Use of betaine HC1 makes it possible to achieve the extremely low pH of 1.5. Further, the combination of HPpCD and low viscosity xanthan gum helped in stabilizing the surfactant, high loading of fragrance, formation of clinging foam without clogging of the spray dispensers.

[0254] Comparative evaluation of the toilet cleaner of the present disclosure with marketed toilet cleaners

[0255] The performance of the toilet cleaner of the present disclosure comprising HPpCD (carrier molecule) low viscosity xanthan gum (rheology modifier) and betaine HC1 (acid component of the effervescent agent) was compared with marketed products comprising citric acid (acid component of the effervescent agent). The marketed products did not contain HPpCD and low viscosity xanthan gum. The results obtained are summarized in Table-4a.

[0256] The toilet cleaner tablet composition (17.35 g) of the present disclosure and the marketed tablets were individually dissolved in 300 ml of water and poured meanwhile the ready to use marketed toilet cleaner samples were used directly in standard toilet cleaning dispenser bottles. The tablet made solutions were dispensed using standard trigger foam pumps designed for toilet bowl cleaning. All the solutions were tested for the following parameters and the results obtained are summarized in Table -4a: effervescence was assessed by maintaining the solutions in the dispenser bottles for 2.5 hours (dissolution time (DT)); dispensing efficiency was tested by actuating trigger foam pumps continuously for 500 times to simulate extended consumer usage;

[0257] - pH of the solutions was measured using calibrated pH meter; foam cling was assessed visually after application in standard ceramic toilet bowl;

[0258] - vapour release was assessed by observing any pungent vapour emissions during product dispensing and application.

[0259] The solutions were classified “Pass” only if: • optimal pH of 1.5 was achieved for tough scale removal;

[0260] • no oozing or overflow from dispenser was observed;

[0261] • no blockage occurred during continuous actuations; and

[0262] • stable foam cling was maintained without release of pungent vapours.

[0263] It is seen from Table-4a that the toilet cleaner of the present disclosure comprising betaine HC1 and the combination of HPpCD with the low-viscosity xanthan gum of the present disclosure was able to achieve a pH of 1.5 and resulted in efficient scale removal in the toilet bowl. No oozing or overflow from the dispenser was observed for the toilet cleaner of the present disclosure. No blockage / clogging was observed during the continuous actuations and further stable foam cling was maintained without pungent vapours for the toilet cleaner of the present disclosure.

[0264] The use of betaine HC1 makes it possible to achieve the extremely low pH of 1.5 along with controlled fizzing that eliminates spilling, which cannot be achieved by using only citric acid. The use of HPpCD stabilized the high fragrance load and the specialized xanthan gum ensured clinging foam without clogging of the spray dispensers.

[0265] Experiment 5: Preparation of the controlled-release, tablet composition for use as a foam spray dishwash in accordance with the present disclosure

[0267] 21. 1 g of the tablet composition obtained in Experiment 5 was dissolved in 300 ml of water to obtain a manual foam spray dishwash having a pH of 11.

[0268] The surfactants (cetyl stearyl alcohol and sodium alpha olefin sulfonate) used in the composition provided the cleaning action in the dishwash. The tablet composition used a strongly alkaline effervescent system to achieve a high pH (pH=ll). The combination of the specialized xanthan gum and the HPpCD-encapsulated fragrances ensured optimal foam consistency without clogging nozzles which was observed in conventional viscous alkaline cleaning solutions.

[0269] Comparative evaluation of the dishwash of the present disclosure with marketed dishwash

[0270] The performance of the dishwash of the present disclosure comprising HPpCD (carrier molecule) and low viscosity xanthan gum (rheology modifier) was compared with marketed products devoid of HPpCD and comprising regular xanthan gum. The results obtained are summarized in Table-5a. The composition (tablet, 21.1 g) of the present disclosure and the marketed tablet were individually dissolved in 300 ml of water and poured in standard dishwash dispensers. The solutions were dispensed using standard dispensers designed for dishwashing. All the solutions were tested for the following parameters and the results obtained are summarized in Table -5 a: dispensing efficiency was tested by actuating trigger foam pumps continuously for 300 times to simulate extended consumer usage;

[0271] - pH of the solutions was measured using calibrated pH meter; - foam cling and soap residue were assessed visually on standard glass and ceramic dishes, post-cleaning and rinsing;

[0272] - water required for rinsing; and

[0273] - plastic and packaging material used.

[0274] It is seen from Table-5a that the dishwashing composition of the present disclosure comprising HPpCD and the low-viscosity xanthan gum provided better results as compared to the conventional gel and bar-based products. The controlled effervescence and minimized spillage ensured user safety and convenience. The pH of 11 resulted in enhanced grease removal, while also exhibiting strong foam cling and residue-free cleaning without pump blockage. Further, the composition of the present disclosure in the form of a tablet significantly reduced water usage and plastic waste, offering advantages in both consumer performance and environmental impact, supporting its commercial viability.

[0295] The use of HPBCD facilitated a high load of the fragrance along with the active agent (sodium salicylate) in the form of inclusion complex and helped in the prevention of oxidation and hydrolysis of the active agent. Further, the low viscosity xanthan gum provided a clear and low viscosity solution, ensuring a smooth and clog-free dispensing of the composition.

[0296] Experiment 12: Preparation of the controlled- release, tablet composition for use as a pet shampoo in accordance with the present disclosure A composition for use as a pet shampoo was prepared using the ingredients as disclosed in Table-12. The shampoo had a mild fragrance and the use of 3-(N-Butylacetamido)-propionic acid ethyl ester acted as an insect repellent. Experiment 12 was carried out following a similar process as provided in Experiment 2.

[0297] 21.95 g of the composition (tablet) was dissolved in 100 ml of water to obtain a petshampoo having a pH of 7.

[0298] The use of carrier molecule (HPBCD) in combination with the rheology modifier (low viscosity xanthan gum) facilitated a high load of the fragrance along with the active agent (3- (N-Butylacetamido)-propionic acid ethyl ester), helped in the prevention of oxidation and hydrolysis of the active agent and provided a clear and low viscosity solution, ensuring a smooth and clog-free dispensing of the composition.

[0299] Experiment 13: Comparative performance evaluation of the carrier molecule and rheology modifier used in the compositions of the present disclosure The performance evaluation of the carrier molecule (HPpCD) and the rheology modifier (low viscosity xanthan gum) used in the compositions of the present disclosure was carried out on the following parameters and the results obtained are summarized in Table-13:

[0300] 5 - the compositions were individually dissolved in potable water at a ratio of 1:5 to 1: 10; each solution was tested with four common dispenser types: foam pump (palm / fmger type), foam pump (trigger type), fine mist finger sprayer, and trigger mist sprayer; each pump or sprayer was actuated 500 times continuously to simulate consumer usage.

[0301] 10 - a test was classified as “Blocked” if dispensing significantly reduced or completely ceased due to blockage; and a test was classified as “Pass” only if consistent spray performance was maintained throughout all 500 actuations. It is seen from Table- 13 that the composition of the present disclosure comprising a combination of HPpCD with a molar substitution in the range of 3 to 4.5 (7* MS) and a low- viscosity xanthan gum consistently enabled reliable dispensing across all tested mechanisms, including foam and trigger sprayers. The other combinations, such as those using maltodextrin or P-cyclodextrin with the low viscosity xanthan gum, exhibited premature pump blockage (within 15 actuations) or failed to form effective inclusion complexes with volatile active agents, limiting their applicability. The combination of HPpCD and low- viscosity xanthan gum system ensured robust performance and compatibility.

[0302] Experiment 14: Comparative dispensing performance study of final solutions obtained by dissolution of tablet compositions with and without foam pump actuators

[0303] The dispensing performance of the solutions obtained by dissolution of tablet compositions with and without foam pump actuators was studied. The foam pump actuators in accordance with the present disclosure featured internally contoured dual -channel dispersion nozzles.
