Description

BIODEGRADABLE COMPLEX OF SHIKIMIC ACID AND ARGININE FORMICROREGENERATION AND SMOOTHENING FIBERS OF DELICATE FABRICFIELD OF INVENTIONThe invention refers to household chemicals and is a vegetal - amino acid composition and its application for preparation of liquid care products for delicate fabrics (silk, wool, cashmere), such as environment-friendly liquid detergent and fabric softener. The invention relates to the vegetal - amino acid composition and is composed of components A and B, where:(A) Shikimic acid or its salts, shikimates;(B) Aliphatic basic a-amino acid with two basic centers, in particular, L-arginine, where mass ratio expressed as active agents, is (0, 001-0, 5):(0, 001-0, 5) %wt, correspondingly.The composition is of natural origin, biodegradable and safe for sensitive skin. The use of the composition allows restoring damaged fibers of delicate fabrics based on various protein molecules, smoothing down micropile, maintaining the initial appearance of clothes and preventing fiber discoloration due to restoring effect. Additionally, the use of shikimic acid, included into the system, contributes to the decrease of bacterial and fungal load on the consumer, maintains long-time cleanliness of delicate fibers and provides safe effect on the skin while wearing clothes.STATE OF THE ARTDevelopment of laundry detergents and fabric conditioners with improved qualities is a relevant task due to its everyday interaction with environment and human body [Poll of 1993 peope through Kantar Profiles / Mintel; A year of innovation in fabric and dish care, 2021, Mintel], Searching for effective active components, which would do well with contaminants and provide longevity of expensive delicate fibers without damaging them, is a promising and relevant sector. Substances of natural origin and substances, manufactured by biotechnologies, which combine effective fabric deterging, skin health support and environmental care, are of special interest.Shikimic acid of vegetable origin is one of such substances. It represents small molecule, which can be produced in the result of chemical synthesis, microbial fermentation and extraction from specific plant species, in particular, from star anise seeds (Latin: Illicium verum). Despite the fact that it is present is a large number of microorganisms and fungi, it is an intermediate metabolite of biosynthetic reactions, and in these reactions, it is presented invery low concentrations. Shikimic acid in significant amount can be found in star anise and its allies only [Ghosh S. et al. , Production of shikimic acid / / Biotechnology advances, 2012], The use of shikimic acid in household chemicals has not been disclosed.Another component, which is widely presented in nature and which at the same time can be potentially used in garment care products, is arginine amino acid. It represents small molecule with weak alkaline properties, the use of which, in combination with other amino acids, is widely spread in hair care products, but not in household chemicals. Arginine is widely used in such areas as protein refolding, solubilization of proteins and small molecules, column chromatography and viral inactivation [Arakawa T., Kita Y. Multi-faceted arginine: mechanism of the effects of arginine on protein, 2014]. In conjunction of household chemicals, arginine- based surface-active agents (SAAs) are known. They present more environmentally friendly substitutes of traditional SAAs and have high antimicrobial activity, being biodegradable and less toxic for environment and human beings. There are three classes of arginine-based SAAs: single-chain, dimeric and arginine-based glycerolipidic conjugates. All these classes represent substances, different from monocomponent arginine in their chemical properties [Singh A., Tyagi V. K. Arginine based, novel cationic surfactants: a review, 2014].The authors of the study assumed that combined use of arginine and shikimic acid in care products for delicate fibers can positively impact on their properties due to microregeneration of thin fragile fibers and subsequent maintenance of fabric color and appearance of garments. The use of the system of arginine and pyrrolidone-carboxylic acid salt to maintain the color of treated hair had been previously described in scientific literature [Oshimura et al., Hair and amino acids: the interactions and the effects / / Journal of cosmetic science, 2007], Nonetheless, this article does not emphasize hair restoring impact at the level of hair ultrastructure. The authors of the article mentioned, that the use of hair conditioner, containing alanine, not arginine, improves hydrophobic properties of dyed blond hair, and such amino acids, as histidine and phenylalanine, increase tensile strength of hair. The system of arginine and pyrrolidone-carboxylic acid salt in the composition of hair shampoo (pH=5.8) in this study was described to retain colorants as water-soluble molecules in color treated hair. The authors studies the referred system only at pH=5.8 and stated that arginine has highest affinity for hair at pH>4 (isoelectric point of hair) [Oshimura et al., Hair and amino acids: the interactions and the effects / / Journal of cosmetic science, 2007],Despite the superficially similar construction, human hair and animal hair, from which woolen fabric are made (mainly, sheep hair), they have a number of differences. For example, merino wool, made of wool-producing merino sheep, has hair cuticle one cell layer wide, whilehuman hair cuticle is made of 10-30 layers [Jones L. N Hair structure anatomy and comparative anatomy / / Clinics in dermatology, 2007], Additionally, as opposed to regular arrangement of human hair scales, wool has less regular cuticle structure and looks less smooth than human hair. Medulla, the central part of hair, is merely present in wool, but is expressly evident in human hair. In particular, this is related to differences in hair diameter: human hair is “thicker” than wool. Beside the above-mentioned parameters, wool has significant advantages over human hair in relation to the parameters, critical in fabric manufacturing; it is softer, more elastic, holds water, moisture and colorants better, has larger gloss and is less prone to ignition [Structure of wool and its differentiation from hair fibre, https: / / sites.google.com / site / viveklpm / wool / structure-of-wool-and-its-differentiation-from- hair-fibre] . Due to wool structure (thinner cuticle and medulla), it is not resistant to some components, contained in hair care products, and requires special care https: / / inthewash.co.uk / laundry-and-ironing / can-you-wash-wool-with- shampoo / #:~:text=In%20particular%2C%20wool%20shampoos%20and,they%20can%20con tain%20harsh%20chemi cal s. I .It follows from the above, that, despite the similar type of construction, wool hair and human hair are different. Thus, data, received for human hair, cannot be directly extrapolated to woolen fabric, and vice versa. To get the data on the impact of any system on woolen fabric, separate studies performed directly on fabrics are required, and the data on properties, received for human hair, is not evident for wool. As technologies allowing restoration of woolen fabrics on microstructural level are unknown, the development of products, which would maintain the initial appearance of wool and / or would restore damaged woolen fabrics, is highly relevant.The authors of the present invention assumed that arginine, being the basic amino acid, can be bound to negatively charged molecules not only on hair surface but also on wool surface. Arginine has positive effective charge, i.e. it is in charged state and is able to bind with negatively charged molecules at pH<9, which corresponds to most garment care products [lew's C. et al. Effect of pH on the binding of sodium, lysine, and arginine Counterions to l- Undecyl Leucinate micelles / / Journal of Surfactants and Detergents. - 2016. - T. 19. - No. . 6. - C. 1175-1188 , The authors propose the following hypothesis: arginine forms a special stoichiometric complex with shikimic acid and operates under the “anchor” principle, i.e. it binds negatively charged molecules on wool surface with shikimic acid. Apart from the fact that arginine is able to bind with negatively charged groups on protein surface, it also contributes to protein refolding [Arakawa T, Kita F. Multi-faceted arginine: mechanism of the effects of arginine on protein, 2014], In conformance with the above mentioned, the authors ofthe present invention propose the following hypothesis: a complex of arginine and shikimic acid exhibit synergic activity in relation to woolen fabric restoration at the ultrastructural level by restoring protein molecule structure. Moreover, shikimic acid, being highly hydrophilic, is hygroscopic, i.e. is able to absorb moisture. As the substances used to color fabrics, are water soluble, this refers to additional effect of the complex, which is retaining fabric color, which preserves the initial appearance of fabrics and increases wear period. Earlier, such or similar properties for garment care products in relation to the complex of arginine and shikimic acid, have not been shown, which emphasizes its uniqueness and innovation.Shikimic acid and arginine are declared as one of Michael acceptor junction and linker, correspondingly, in Patent Application US20190240126 (KEMON S P A [IT]). This patent application covers cosmetic composition for topical application, containing 30-95% w / w of active component, to restructure and protect hair and scalp by restoring disulfide bonds, which are broken in damaged hair and scalp, while the specified active agent contains mixture of at least one acyclic terpene and at least two Michael acceptor junctions and 5-30% w / w of at least one linker per the weight of the specified active component and at least one specified linker. It follows from the application, that the composition of the active complex, in addition to shikimic acid and arginine (as one of the linkers), one more acceptor junction (sorbic acid) and one acyclic terpene must be present. This composition is designed especially for hair, which, as it was described earlier, has a significant number of differences from wool. Moreover, despite the fact that the patent application specified the range of working pH from 2 to 10, pH is not specified in the section with the embodiments of the invention. Due to this, it is impossible to certainly decide on the range of working pH values. It is worth mentioning that most shampoos and conditioners have pH<5, which can be the base of interpretation of the use of the given composition in hair care products.Arginine is used not only in hair care products, but also in compositions designed for garment care. In particular, the use of arginine in the composition for stain removal from fabrics with surface active agent is described in Patent Application WO2014095617 (UNILEVER PLC [GB]). Nonetheless, this patent application does not disclose arginine composition to restore fabrics, in particular, delicate fabrics. The effect of the composition is limited to removal of stains of lipid origine, as the embodiments in the patent application included samples of fabrics with beef fat stains as test samples.The use of arginine is also described in Patent Application W02004038084 (international patent application, CLOROX CO [US], ADAIR MARTHA J [US]...) in the composition, where arginine acts as chlorine and / or active oxygen absorbent or neutralizer.The composition is presented in liquid, liquid gel or gel form and is designed for use in fabric care, in particular, to protect fabrics from color damage. The formulation of the declared composition is as follows: (a) from about 0.001% to about 5% by weight of one or more enzymes for fabric care, which are effective in prevention of pilly gameting, stain formation and other damages to fibers during laundry; (b) from about 0.001% to about 20% by weight of one or more UV-screening agents, where one or several UV-screening agents are for bleaching and prevention of photo-discoloration and other damage to fabrics by light; (c) from approximately 0.001% to approximately 60% by weight of one or more surface-active dispersing, emulsifying and / or solubilizing agents; (d) from about 0% to about 20% be weight of one or more dye transfer inhibitors, agents, preventing reprecipitation, or colorant sequestrants; (e) from about 0% to about 20% by weight of one or more colorants, color pigments and fabric color fixer or protector for fabric finish; (f) from about 0% to about 5% by weight of one or more textile lubricants and / or fabric softeners. Arginine, in its turn, is declared as chlorine and / or active oxygen absorbent or neutralizer, which act as agents, contributing to fabric discoloration. The embodiments include the studies of tensile strength, but not fabric discoloration inhibition or fiber restoration of delicate fibers at the microscopic level.The use of arginine is also declared in garment care conditioning products (US6750189 (PROCTER & GAMBLE [US]) and WO2016106362 (international patent application, INTERNATIONAL FLAVORS & FRAGRANCES INC. [US])). In the first patent, arginine is declared not as a separate component, but in the composition of homo- / cocondensate, copolymer of amino acids or cross-linked polymer, the properties of which can be different from unbound arginine due to their physical and chemical nature, in particular, dimension and composition of molecules.In Patent WO2016106362, arginine is declared as a stabilizing agent in the formulation of the composition: from 1 to 30% of conditioning agent for fabrics, from 0.1% to 30% of the capsule, having oil kernel and wall of the capsule, where the oil kernel contains active material and the capsule wall, incapsulating oil kernel, and 20 ppm or more of the stabilizing agent. The active material is flavoring agent, designed to eliminate odor, or a combination of them. The patent application did not include any tests to estimate softening effect, fiber restoration or color maintenance, despite the declared effect in fabric care.Kitchen spray (Kitchen Cleaner, Happy Elephant, SARAYA) is available in the market. Its formulation includes surfactants (1% sophorolipids), arginine (additive), ethanol (stabilizer), citric acid (pH adjustor). In the manufacturer’s website this product is promoted as an effective and safe product, composed of food ingredients, to remove stains of lipid nature,streak-free. Despite the presence of garment care products in the Happy Elephant product line (https: / / happyelephant.info / products / kitchencleaner.html), the formulation of them does not include arginine and shikimic acid, which shows that the manufacturer does not use arginine and shikimic acid as functional additive to restore fabrics. At the same time, the function of arginine in the kitchen spray is not clarified.Thus, it was found out, that the use of shikimic acid and arginine for deep restoration and further color maintenance of delicate fabrics, in particular, wool, is not disclosed. Despite of the fact that arginine is included into the compositions for garment care and household care products, its activity in restoration of delicate fabrics and color maintenance has not been demonstrated earlier. The authors of said invention discovered unique effect of the composition for restoration of delicate fabrics, in particular, decrease of striation of separate fibers, and protection from dye bleeding. The effectiveness of the given complex is evident in the range of concentrations from 0.001% to 0.5% in 1 : 1 ratio pH=3-8.The acquired effect is more probably explained by the formation of stoichiometric complex, composed of arginine and shikimic acid, which is bound with wool surface under the “anchor” principle, fixing these components on hair. Being attached and integrated into wool fibers at the ultrastructural level, the complex contributes to the restoration of woolen fabrics, as well as sustaining colorant molecules on the surface of woolen and other fabrics.Due to the fact that the complex includes shikimic acid and arginine - the substances, which are normally contained in living organisms, the complex is environmentally friendly and safe for skin in stated concentrations. Moreover, arginine and shikimic acid have positive impact on skin; in particular, products, containing these components, contribute to the reduction of atopic dermatitis symptoms [Batory M., Rotsztejn H. Shikimic acid in the light of current knowledge, 2022; Zhang Y. et al. Skin care product rich in antioxidants and. antiinflammatory natural compounds reduces itching and inflammation in the skin of atopic dermatitis patients, 2022 ,Thus, the invention as whole relates to the complex of shikimic acid and arginine and its application in the composition of various household chemicals, allowing such technical results as restoration of delicate fabrics and preservation of fabric color, which are not achieved or achieved insufficiently with modem commercially available products in the art.PURPOSE OF THE INVENTIONIn the first aspect, the invention relates to the vegetal - amino acid composition based on shikimic acid and arginine as a synergist for the use in household chemicals and laundry detergents, active at pH 2.5-9.5.

For this, liquid detergents were prepared (Formula No. 1, 2, 3, 4), in particular, multi-functional laundry detergent for white and colored fabrics with various concentrations of active components, under the invention (Table 1). pH of the product = 8-9.Table 1. Formulation of liquid laundry detergent.Table 2. Formulation of liquid laundry detergent with shikimic acid and arginine.Table 3. Formulation of liquid laundry detergent with shikimic acid and arginine.Table 4. Formulation of liquid laundry detergent with shikimic acid and arginine.The prepared liquid detergents and stain removers provide high efficiency of cleaning and elimination of odor for delicate fabrics with any tap water hardness 0-5 mg-equ / L and at any washing temperature from +15°C to +60°C. The product does not cause discoloration of fabric and dye bleeding, maintains the initial appearance of garment, streak-free, completely washes off fabric surface, suitable for children’s laundry and people with sensitive hand skin.Embodiment 2.Shikimic acid was studied in the composition of various household chemical products. To do this, liquid detergents (Formula No. 5, 6, 7, 8), in particular, laundry and freshener conditioner with different concentrations of shikimic acid and arginine, were prepared within the scope of the invention (Table 2). The pH of the means = 2.5-3.5.Table 5. Formulation of fabric conditioner.Table 6. Formulation of fabric conditioner with shikimic acid and arginine.Table 7. Formulation of fabric softener conditioner shikimic acid and arginine.Table 8. Formulation of fabric conditioner with shikimic acid and argininePrepared laundry conditioner provides softening and easier ironing of various fabrics, in particular delicate fabrics, with any hardness of tap water 0-5 mg-eq / 1 and at any washing temperature from +15°C to +60°C. It does not cause discoloration of fabrics and dye washout, streak-free, is suitable for washing children's laundry and for people with sensitive hand skin.Embodiment 3.The effectiveness of the composition of shikimic acid and arginine in the formulation of multipurpose liquid detergent in restoring woolen fibers was studies in the laboratory. Liquid multipurpose detergent for white and color fabrics, specified in Table 1, and laundry conditioner, specified in Table 5, were used as the basis for the components.Method of scanning electron microscopy (scanning-electron microscope FEI Teneo, 2015) was used for detailed study. Samples of woolen fabric (Fig. 1), cut into squares with 2 cm sides, were used as the study object. The samples were washed in Miele washing machine (W1 with PowerWash, TwinDos, Steam technologies). To estimate the damage ratio of the fibers, the authors of the present invention implemented a 3-point scale, where 1 is the most stippled (the most damaged) wool hair, and 3 is the smoothest (the most restored) wool hair (Fig. 3). The striation ratio of individual wool hair impacts not only the ultrastructure of woolen fabric, but its appearance. Due to the reflective power of wool, the fabric, which includes more stippled wool hair, looks duller, which impacts the appearance of the garment, made of delicate fabric, in whole.Figure No. 3. Microphotography of woolen fabric before treatment with protease, made with scanning electron microscopy, 5000x magnification.For detailed study of the impact of the innovation composition on restoration of wool, the microstructure of the fabric was first screened with a scanning-electron microscope to register the initial (non-damaged) condition of wool. Pictures, presented in Fig. 3, were made. Average striation ratio was 2.44 ± 0.63 c.u. (Table 9).Table 9. Changes in woolen fabric striation after washing with the innovation system.**As a control for samples No. 1-4 the value of striation before treatment is used, for samples No. 5-8 the value of striation after its treatment with protease is used.Next, the fabric was damaged by washing in the “Wool Fabric” mode for 39 minutes with a base wash gel from Table No. 1 (without shikimic acid and arginine) containing protease (EC 3.4.21.14, CAS 9014-01-1, Novozymes) in concentration of 0.25 %wt. After this step, the samples were resubmitted for imaging to record the condition of the wool after fiber damage (Figure 4). The average striation ratio was 2.23 ± 0.63 c.u. (Table 9).Next, to evaluate the recovery effect of the “shikimic acid + arginine” system, the wool fabric samples were washed with laundry and care products presented in Tables 1, 4, 5, 8 in the following pattern:After this step, the ultrastructure of wool samples was again analyzed by scanning electron microscopy to assess the degree of wool tissue recovery after exposure to the innovative system (Fig. 5). The striation ratio of the samples is presented in Table 9.Within additional tests to evaluate fiber recovery at lower component concentrations of 0.01 %wt and 0.001 %wt, 4 samples of untreated wool fabric were taken and washed in“Express Wash” mode for 20 minutes with laundry and care products shown in Tables 1, 2, 3, 5, 6, 7 in the following pattern:Due to the fact that no statistically significant difference (Mann-Whitney criterion, p- value > 0.05) was found between striation ratio of wool before and after protease treatment, further study was conducted without pretreatment with protease and the average striation ratio of untreated wool was used as the control.The obtained samples were then also examined by evaluating the wool microstructure using scanning electron microscopy and the resulting micro-images (Fig. 6) were analyzed using the scale shown in Figure 2. The striation ratio of the samples is presented in Table 9.To compare the effect of fabric recovery after washing with the components of the innovative composition in different variations, the average value in each sample was taken and compared with the control - for wool samples 1-4 - the average striation ratio after protease treatment, for wool samples 5-8 - the average striation ratio of control samples without damage. The results obtained by processing the obtained data are summarized in Fig. 7 and Table 9. The value of the bar represents the reduction of the striation compared to the control, in %.As follows from to the data obtained, the composition with the concentration of arginine and shikimic acid 0.001 %wt and 0.001 %wt reduces striation by 30.9%, with concentrations of 0.01 %wt and 0.01 %wt - by 26.15%, with concentrations of 0.25 %wt and 0.25 %wt - by 19.4%. Thus, the effectiveness in reducing the striation is achieved with both high and low concentrations, so the working range of the components of the composition is in the range from 0.001 %wt to 0.25 %wt of arginine and from 0.001 %wt to 0.25 %wt of shikimic acid, and the composition can be used in both laundry gels and conditioners.It is worth noting that the reduction in recovery ration as compared with the control in the system “laundry gel base + conditioner with shikimic acid 0.25 wt.% and arginine 0.25 wt.%” can be offset by the combined use of conditioner with laundry gel that contains the innovation combination (Sample No. 4). Despite the reduction in recovery ratio as compared with the control, the system “laundry gel base + conditioner with shikimic acid 0.25 wt.% and arginine 0.25 wt.%” also has a restorative effect on wool fabric, remaining in the positive zone.Thus, the authors showed an unexpected technical result: when using a combination of shikimic acid and arginine there occurs restoration of wool fabric at the microstructural level, which in turn improves the appearance of the garment as a whole and makes it more durable. This technical result has not been previously described in the literature and has a practical value for increasing the life of garments made of delicate fabrics, reducing the stress for the environment and allowing the competent use of available resources.Embodiment 4.A laboratory study of the effectiveness of the innovation composition of shikimic acid and arginine in the formulation of multipurpose liquid laundry detergent in preserving the color of fabric was carried out. As the base for the introduction of components laundry conditioner, specified in Table 5, was used with the concentration of shikimic acid and arginine 0.001 wt.% and 0.001 wt.% (Table 6), as well as liquid multipurpose detergent for white and color fabric, specified in Table 1, which does not contain any components of the innovation composition. As comparison objects, 4 commercially available laundry gels were used that were promoted as laundry detergents for black fabrics, which are now and hereinafter designated as:1) Laundry gel for black fabrics No. 12) Laundry gel for black fabrics No. 23) Laundry gel for black fabrics No. 34) Laundry gel for black fabrics No. 4Delicate fabric of blue color, size 50 mm x 100 mm, water hardness 5.35 mg*eq / dm3 was used as test samples; the solution of the test means was prepared according to the method of application for hard water.The essence of the method to determine color retention when using laundry and care products is photometric determination of the changes in the reflection power of the surface of the fabric treated with the test product in comparison with a control sample treated with water.Three fabric samples were taken for testing, two of which were treated with the test agent, the third one was treated with hard water. The fabric samples were washed for 20 min at the temperature of 40°C. After the fabric samples were rinsed, dried, ironed, and the reflection power was measured. This procedure was repeated 10 times, and after 1, 5 and 10 washings, reflection power was measured. In each washing cycle, 50 ml of laundry gel (Table No. 1) containing no shikimic acid and arginine and 30 ml of laundry conditioner (Table No. 6) were used. The results of the study are summarized in the graph below (Figure 8).It follows from the graph that using the base of multipurpose laundry gel together with laundry conditioner containing the components of the innovation composition contributes to significant color retention with a value of 96.15% as compared to the maximum value of 87.8% for black fabric laundry gel No. 1 and No. 2. Commercially available black fabric laundry gels No. 1 and No. 2, which do not contain the innovation composition of shikimic acid and arginine in the composition, do not allow color retention as a color loss of more than 10% is indicative of the visible color loss.Thus, the authors of the invention have shown an unexpected technical result: the innovation composition based on shikimic acid and arginine not only restores the fibers of wool fabric with reduced strength characteristics, but also contributes to the preservation of fabric color. These effects make it possible to preserve the original appearance of the garment and restore the damaged fabric. This technical result has not been previously described in the literature and has practical value for increasing the life of garments made of delicate fabrics, reducing the stress for the environment and allowing the competent use of available resources.
