Abstract
Description
Technical Field
[0001] The present invention relates to a perfumed consumer product containing a fragrance precursor compound and a trigger, wherein the fragrance precursor compound or the trigger is contained in particles, or the fragrance precursor compound and the trigger are contained in separate particles, or the fragrance precursor compound and the trigger are contained in separate compartments, so that the fragrance precursor compound and the trigger are physically separated, and to the use or method of the perfumed consumer product for imparting, enhancing, improving or modifying the fragrance effect of an article.
Background Art
[0002] Fragrance precursor compounds are known to those skilled in the art, and when triggered by external stimuli such as contact with moisture and / or exposure to light and / or a temperature increase and / or an oxidative environment and / or contact with an activator, they release fragrance components, particularly olfactory fragrance components, and the kinetics of fragrance release for inducing a sensory effect by its continuous release are controlled to a certain extent.
[0003] However, the unstable nature of the fragrance precursor compound with respect to a specific trigger poses problems regarding the stability of the fragrance precursor compound, the controlled release of the fragrance precursor compound by the trigger, and the persistence of the olfactory effect in a specific application. For example, if the contact or reaction between the fragrance precursor compound and its corresponding trigger is too fast, the release of the fragrance component by the fragrance precursor compound becomes too fast, resulting in the provision of the fragrance effect becoming too fast. That is, it cannot be utilized over an extended period until needed or at a specified time point. This is particularly a problem for the application of enzyme-degradable fragrance precursor compounds when enzymes are present, such as in laundry detergents.

Preferred polyurea microcapsules include a polyurea wall which is a reaction product of polymerization between at least one polyisocyanate containing at least two isocyanate functional groups and at least one reactant selected from the group consisting of amines (such as water-soluble guanidine salts and guanidine); a colloid stabilizer or emulsifier; and an encapsulated fragrance precursor compound or trigger. However, the use of amines can be omitted.
[0043] According to a particular embodiment, the colloid stabilizer comprises an aqueous solution of 0.1% - 0.4% polyvinyl alcohol and 0.6% - 1% of a cationic copolymer of vinyl pyrrolidone and quaternized vinyl imidazole (all percentages are defined by mass relative to the total mass of the colloid stabilizer). According to another embodiment, the emulsifier is preferably an anionic or amphiphilic biopolymer selected from the group consisting of gum arabic, soy protein, gelatin, sodium caseinate and mixtures thereof.

[0122] Example 2: Preparation of Low-Aqueous Liquid Detergent Formats in Single-Chamber and Dual-Chamber Pods The model liquid base used was C 12~15 a low-water liquid detergent consisting of Paless 7, MEA-hydrogenated cocoate, MEA-dodecylbenzenesulfonate, propylene glycol, glycerin water, polyvinyl alcohol, polypropylene terephthalate polyoxyethylene terephthalate, sorbitol, sodium diethylenetriamine pentamethylene phosphonate, MEA-sulfate, potassium sulfite, ethanolamine, peptide salt, glycol, subtilisin, fragrance, disodium distyrylbiphenyl disulfonate, talc, amylase, lipase, sodium chloride, disodium benzoate, disubstituted alanine amide, dye, mannanase. This composition contains an anionic surfactant, a nonionic surfactant, soap in the range of 5 - 15% and an enzyme mixture of less than 5%, and does not contain lipase, a fluorescent whitening agent, a fragrance, a phosphonate. The basic pH should be >7.
[0123] 27 g of a single-chamber liquid base detergent formulation was prepared according to the above formulation, and lipase (0.01 g) was added. Fragrance A (0.54 g) and (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate (0.88 g) were added to this formulation. This formulation was introduced into a polyvinyl alcohol pouch.
[0124] A double-chamber liquid-based detergent formulation was also prepared to obtain a 20 g perfumed chamber without lipase and an unperfumed 7 g chamber with lipase (0.01 g). In the 20 g chamber, compared to the single-chamber pouch, fragrance A (0.54 g) and (E)-3,7-dimethylocta-2,6-dienyl hexadecanoate (0.88 g) were added so that the same amount of fragrance and lipase was supplied per wash. These formulations were introduced into double polyvinyl alcohol pouches.
[0125] Example 3: Storage stability of (E)-3,7-dimethylocta-2,6-dienyl hexadecanoate in a low-aqueous liquid detergent format a. Protocol The stability of (E)-3,7-dimethylocta-2,6-dienyl hexadecanoate was tested in a low-aqueous liquid detergent base in the pod under two formats prepared according to Example 2, namely a single-chamber and a double-chamber format for separating lipase from the fragrance precursor compound.
[0126] The amount of 3,7-dimethylocta-2,6-dien-1-ol released by the degradation of (E)-3,7-dimethylocta-2,6-dienyl hexadecanoate induced by lipase was measured over time by GC / MS at both 22 °C and 35 °C, and how (E)-3,7-dimethylocta-2,6-dienyl hexadecanoate was degraded could be determined.
[0127] b. Results These results are summarized in Table 1 below.
[0128] [Table 4]
[0129] c. Conclusion The loss of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate was found to be very high under soft storage conditions (22 °C) and under stressed storage conditions (35 °C) during storage in a single-chamber pod product containing lipase. In fact, in both cases, almost complete decomposition of the fragrance precursor compound occurred after only 3 days. Nevertheless, in the double-chamber pod format where (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate in one chamber was separated from the lipase, the stability of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate was excellent.
[0130] Example 4: Olfactory performance of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate in a liquid-based detergent formulation in a pod The olfactory performance of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate was tested in a low-aqueous liquid detergent base under two formats prepared according to Example 2, i.e., in single and double-chamber pods to separate the lipase from the fragrance precursor compound.
[0131] a. Protocol Single and double-chamber pods prepared in Example A were stored at 37 °C for 2 weeks and then used to wash fabric (2.0 kg of cotton terry towel) at 40 °C in a standard European horizontal-axis machine (Miele Novotronic W900-79CH).
[0132] Pods containing one or two chambers were placed in the washing machine drum at the start of the wash. After washing, the fabric was line-dried overnight and then the odor intensity of the cotton towel was evaluated by a panel of 20 trained panelists. The panelists were asked to rate the odor intensity of the towel on a scale of 1 to 7, where 1 corresponds to no odor and 7 corresponds to a very strong odor.
[0133] b. Results The results are shown in Table 2 below.
[0134]
Table 5
[0135] c. Conclusion (E)-3,7-Dimethyl-2,6-octadienyl hexadecanoate has significantly stronger overall fragrance intensity on dry fabric than on fabric washed in a double-compartment chamber. When the lipase and the fragrance precursor compound are formulated in separate chambers, there is an additional advantage in that the fragrance precursor compound is stable in the product, while when there was only one chamber, it was actually unstable.
[0136] Example 5: Storage Stability of (E)-3,7-Dimethyl-2,6-octadienyl Hexadecanoate in a Liquid-Based Detergent
Table 6
[0137] a. Protocol The stability of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate in a liquid-based detergent formulation as reported in Table 4 was tested. This detergent formulation was added to a single-compartment bottle or a double-compartment bottle. In the case of the single-compartment bottle, lipase and (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate were added to the bottle. In the case of the double-compartment bottle, the detergent was introduced into both compartments by adding lipase to one compartment and (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate to the second compartment.
[0138] (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate concentration was equivalent to 1% in the liquid-based detergent formulation. The amount of geraniol released by lipase-induced degradation of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate was measured over time at both 22 °C and 35 °C by GC / MS, and it was possible to determine the extent to which (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate was decomposed.
[0139] b. Results The results are summarized in Table 4 below.
[0140]
Table 7
[0141] c. Conclusions It can be concluded that the loss of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate during storage in a liquid detergent containing lipase was very high under both soft storage conditions (22 °C) and storage conditions under stress (35 °C). In fact, in both cases, after only 3 days, the fragrance precursor compound was almost completely decomposed. Nevertheless, when the liquid detergent was contained in a double-chamber PET bottle in which (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate in one chamber was separated from the lipase in another chamber, the stability of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate was excellent.
[0142] Example 6: Storage Stability of (E)-3,7-Dimethyl-2,6-Octadienyl Hexadecanoate in a Powder Detergent a. Composition The tests were carried out using a basic powder detergent formulation containing sodium sulfate, sodium carbonate, sodium dodecylbenzene sulfonate, sodium silicate, zeolite, C 12~15 Palex-7, bentonite, citric acid, sodium acrylate / MA copolymer, sodium carbonate, sodium peroxide, tetrasodium etidronate, sodium chloride, sodium bicarbonate, cellulose gum, disodium anilinomorpholinotriazinylaminostilbenesulfonate, phenylpropyl dimethicone, enzyme (not containing lipase), and dye in the following amounts.
[0143] [Table 8]
[0144] 0.7% of fragrance B and 0.5% of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate were added to the powder detergent formulation, and the mixture was mixed. Then, 0.4% of either liquid lipase or granular lipase was added to the flavored powder detergent base, and the mixture was mixed.
[0145] b. Protocol 24 cotton terry towels were washed at 40 °C in a standard European horizontal axis machine (Miele Novotronic W900-79CH) in the presence of 80 g of a perfumed bio powder detergent. The powder was supplied via the drawer of the washing machine. After washing, the fabric was line dried overnight and then the odor intensity of the cotton towels was evaluated by a panel of 10 expert panelists. The panelists were asked to rate the odor intensity of the towels on a scale of 1 to 7, where 1 corresponds to no odor and 7 corresponds to a very strong odor.
[0146] c. Results The results are shown in Table 5 below.
[0147]
Table 9
[0148] d. Conclusions After drying, the powder detergent base containing granular lipase was perceived more strongly than an equivalent base without lipase or a base containing lipase that was in direct contact with the perfume precursor compounds in the powder detergent, regardless of the evaluation stage (fabrics dried for 1 day, 3 days, and 7 days). Liquid lipase was in direct contact with the perfume precursor compounds in the powder detergent, and as a result, its performance was lost after storage at 37 °C for 2 weeks due to the decomposition of the perfume precursor compounds by the trigger. Similar to the liquid enzyme, when granular lipase was used in combination with a powder detergent containing perfume precursor compounds, the stability and performance of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate remained good even after a concentrated storage test at 37 °C for 2 weeks.
[0149] Example 7: Olfactory Performance of (E)-3,7-Dimethyl-2,6-Octadienyl Hexadecanoate in a Urea-Based Granular Base a. Composition A urea-based granular base formulation having the following final composition was prepared.
[0150]
Table 10
[0151] To the urea beads, 6% of fragrance B and 5% of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate were added, and the mixture was tumble-mixed. Then bentonite was added to the flavored urea beads, and the mixture was tumble-mixed. Finally, the lipase was added in either granular or liquid form, and the mixture was tumble-mixed so that the urea and bentonite surfaces were completely coated with the fragrance (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate and the lipase.
[0152] b. Protocol In the presence of 36 g of unflavored non-bio powder detergent and 18 g of the granular base formulation prepared in Example 7a) and aged in an oven at 37 °C for 2 weeks, 24 cotton terry towels were washed at 40 °C in a standard European horizontal-axis machine (Miele Novotronic W900 - 79CH). The powder was supplied through the drawer of the washing machine, while the granular base formulation was placed inside the drum of the washing machine at the start of the wash. After washing, the fabric was line-dried overnight, and then the odor intensity of the cotton towels was evaluated by a panel of 10 expert panelists. The panelists were asked to evaluate the odor intensity of the towels on a scale of 1 to 7, where 1 corresponds to no odor and 7 corresponds to a very strong odor.
[0153] c. Results These results are shown in Table 6 below.
[0154]
Table 11
[0155] d. Conclusion In the case of the granular urea base, the performance in a single dry fabric with (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate was slightly stronger than that of a base without lipase or a base containing free liquid lipase even after a very severe storage test at 37 °C for 2 weeks when the base contained granular lipase. This again indicates that the flavor precursor compound was separated from the granular lipase trigger and withstood a very severe storage test at 37 °C for 2 weeks.
[0156] Example 8: Olfactory performance of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate in a granular PEG base a. Composition A granular PEG base formulation having the following final composition was prepared.
[0157] [Table 12] 1) DETE-2624, an alkaline lipase for detergents, in powder form, obtained from Creative Enzyme.
[0158] 26% dextrose was added to the PEG base and the mixture was melted at 80 °C. Then 6% flavor B and 5% (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate were added and mixed. Finally, lipase was added in either granular or liquid form and gently mixed to maintain the integrity of the lipase granules. The mixture was then pelletized while cooling by pouring a thin film of the molten mixture onto a flat surface and cutting into small pieces after solidification.
[0159] b) Protocol 24 cotton terry towels were washed at 40 °C in a standard European horizontal-axis machine (Miele Novotronic W900-79CH) in the presence of 36 g of an unscented non-bio powder detergent and 18 g of a granular base formulation prepared in Example 8 and aged in an oven at 37 °C for 2 weeks. The powder was supplied via the drawer of the washing machine, while the granulated base formulation was placed in the drum of the washing machine at the start of the wash. After washing, the fabric was line-dried overnight, and then the odor intensity of the cotton towels was evaluated by a panel of 10 expert panelists. The panelists were asked to evaluate the odor intensity of the towels on a scale of 1 to 7, where 1 corresponds to no odor and 7 corresponds to a very strong odor.
[0160] c) Results These results are shown in Table 7 below.
[0161]
Table 13
[0162] d) Conclusions After drying, the granulated PEG-based product containing granular lipase outperformed an equivalent base that either did not contain lipase or contained lipase that was in direct contact with the fragrance precursor compound in the PEG granules at all stages evaluated (fabrics dried for 1 day, 3 days, and 7 days). When lipase was in direct contact with the fragrance precursor compound in the PEG granules, all performance was lost during storage because the fragrance precursor compound was decomposed by the trigger. In contrast, when granular lipase was used in combination with PEG granules containing the fragrance precursor compound, the stability and performance of (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate were not affected even after a very severe storage test at 37 °C for 2 weeks, even when (E)-3,7-dimethyl-2,6-octadienyl hexadecanoate was present in the same product.
[0163] Example 9: Storage Stability of Non-2,6-dien-1-yl Palmitate in a Liquitab Formulation a) Protocol The stability of non-2,6-dien-1-yl palmitate was tested in a liquitab base under two formats: single and double chambers to separate lipase from the fragrance precursor compound.
[0164] The model liquitab base used was C 12~15 a low-water liquid detergent consisting of Paless 7, MEA-hydrogenated cocoate, MEA-dodecylbenzenesulfonate, propylene glycol, glycerin water, polyvinyl alcohol, polypropylene terephthalate polyoxyethylene terephthalate, sorbitol, sodium diethylenetriaminepentamethylenephosphonate, MEA-sulfate, potassium sulfite, ethanolamine, peptide salt, glycol, subtilisin, fragrance, disodium distyryl biphenyl disulfonate, talc, amylase, lipase, sodium chloride, disodium benzoate, disubstituted alanine amide, dye, mannanase. This composition contains an anionic surfactant, a nonionic surfactant, soap in the range of 5 - 15% and less than 5% enzyme, fluorescent brightener, fragrance, phosphonate. The basic pH should be 7 or more.
[0165] The concentration of non-2,6-dien-1-yl palmitate in the liquitab corresponded to 1%. The amount of 2,6-nonadien-1-ol released was measured by GC / MS at room temperature.
[0166] b) Results These results are shown in Table 8 below.
[0167] [Table 14]
[0168] c) Conclusion Single-chamber liquid tablets containing lipase showed poor stability of nona-2,6-dien-1-yl palmitate. In the formulation, degradation started after just a few minutes, and already about 70% of 2,6-nonadien-1-ol was released after only 1 hour. However, no instability was observed in double-chamber liquid tablets where nona-2,6-dien-1-yl palmitate was physically separated from lipase in two different chambers.
[0169] Example 10: Olfactory performance of nona-2,6-dien-1-yl palmitate in liquid tablets a. Composition Same as Example 9 above.
[0170] b. Protocol Using samples stored at 37 °C for 2 weeks, fabric (2.0 kg of cotton terry towel) was washed at 40 °C in a standard European horizontal-axis machine (Miele Novotronic W900-79CH). 27 g of single-chamber liquid tablets were prepared into polyvinyl alcohol pouches according to the above formulation and flavored with 2% by weight of fragrance A and 3.24% by weight of nona-2,6-dien-1-yl palmitate. Double-chamber liquid tablets were also prepared to obtain a 20 g flavored compartment without lipase and a 7 g unflavored compartment containing lipase. The applied amounts were adjusted accordingly so that the same amounts of fragrance and lipase were supplied per wash (fragrance A was 2.7% by weight and nona-2,6-dien-1-yl palmitate was 4.4% by weight).
[0171] At the start of the wash, the pod was placed in the drum of the washing machine. After washing, the fabric was line-dried overnight, and then the smell intensity of the cotton towel was evaluated by a panel of 20 trained panelists. The panelists were asked to evaluate the smell intensity of the towel on a scale of 1 to 7, where 1 corresponds to no smell and 7 corresponds to a very strong smell.
[0172] c. Results These results are shown in Table 9 below.
[0173]
Table 15
[0174] d. Conclusion The overall fragrance intensity in the dry fabric with nona-2,6-dien-1-yl palmitate was significantly stronger with respect to the fabric laundered using a double-compartment chamber. Having lipase and the fragrance precursor compound formulated in a separate chamber provided an additional benefit due to the stability of the fragrance precursor compound in the product, while on the other hand, the fragrance precursor compound was actually unstable when there was only one chamber.
[0175] Example 11: Olfactory Performance of (E)-3,7-Dimethyl-2,6-octadienyl Hexadecanoate in a Single-Chamber Liquid Tab a. Composition Same as Example 9 above.
[0176] b. Capsule Preparation
Table 16
[0177] An oil phase was prepared by mixing a core oil consisting of a polyisocyanate (trimethylolpropane adduct of xylylene diisocyanate, Takenate® D-110N, obtained from Mitsui Chemicals) and a perfume oil. The oil phase consisted of 2% Takenate® D-110N and 98% core oil. After encapsulation and crosslinking the melamine-formaldehyde wall using Takenate® D-110N, the residual level of unreacted polyisocyanate in the core oil was very low, and thus the inner core of the capsule consisted only of the core oil which was the perfume oil.
[0178] To produce the capsule slurry, an acrylamide and acrylic acid copolymer and a blend of two types of melamine-formaldehyde resins were dissolved in water to form an aqueous phase. Then, the perfume premix oil was added to this solution and the pH was adjusted to 5 with acetic acid. The temperature was raised to 90 °C over 2 hours to cure the capsules. At this point, the capsules were formed, crosslinked, and stabilized. In the case of cationic polymer-coated capsules B, a 3% aqueous solution of Salcare SC60 (acrylamide propyltrimonium chloride / acrylamide copolymer) was added to the mixture at 90 °C and reacted at 90 °C for 1 hour. In the case of uncoated capsules A, only water was added at 90 °C, and then this slurry was left at 90 °C for an additional 1 hour. Then, a solution of ethylene urea (50% by mass in water) was added as is normally done using aminoplast capsules as a scavenger for residual free formaldehyde. The final slurry contained approximately 3% w / w ethylene urea based on the mass of the slurry, and this mixture was left to cool to room temperature. The final pH was adjusted to 7 with sodium hydroxide.
[0179] c. Protocol Using the samples stored at 50 °C for one week, the fabric (2.0 kg cotton terry towel) was washed at 40 °C in a standard European horizontal axis machine (Miele Novotronic W900-79CH). According to the above formulation, 27 g single chamber liquid tablets were prepared into polyvinyl alcohol pouches and the same amount of fragrance was used per wash with 2.4% fragrance C or 8.3% of the capsules prepared as described above.
[0180] The pods were placed in the washing machine drum at the start of the wash. After washing, the fabric was line dried overnight and then the odor intensity of the cotton towel was evaluated by a panel of 20 trained panelists. The panelists were required to evaluate the odor intensity of the towel before and after gently rubbing the fabric by hand on the first day to assess the intensity of the fragrance precursor, and then only before rubbing on the third and seventh days, on a scale of 1 to 7 corresponding to odorless 1 and very strong odor 7.
[0181] d. Results These results are shown in Table 10 below.
[0182]
Table 17
[0183] e. Conclusions The overall fragrance intensity in the dry fabric was significantly stronger for the fabric washed with microcapsules. A protective effect of the capsules on the fragrance was observed on the first day when evaluated before and after rubbing the fabric.
