Description

[Technical Field]

[0001] The present invention relates to a hair cleansing agent, in particular to a hair cleansing agent comprising a dermatologically acceptable vehicle, a dermatologically acceptable hair care cleansing surfactant, a dermatologically acceptable silicone, and a deposition aid polymer, wherein the deposition aid polymer is a dextran polymer crosslinked with a dextran crosslinker of formula (I):

[0002] [ka] wherein X is a halogen and each R 1 are independently substituted or unsubstituted C 1~6 alkyl groups, and each R 2 independently, C 1~6 The deposition aid polymer is selected from the group consisting of alkanediyl groups, and Y is a divalent bridging group, which enhances the deposition of dermatologically acceptable silicone from the hair cleanser onto mammalian hair.

[0003] Silicone deposition is of particular interest for a variety of personal care compositions, especially personal care cleansers (e.g., body washes, face washes, hand washes, soaps, shampoos, shampoo conditioners, and hair conditioners) that provide moisturizing / conditioning benefits in addition to cleansing benefits.

[0004] Hair cleansing has become a ubiquitous element of personal hygiene. Hair cleansing facilitates the removal of dirt, bacteria, and other substances that are perceived as harmful to hair or individuals. Cleansing formulations usually contain surfactants to facilitate the removal of substances attached to hair. Unfortunately, cleansing formulations remove both undesirable and desirable substances from hair. For example, undesirably, cleansing formulations often remove oils from hair, which act to protect hair from moisture loss. Removing excessive oils from hair can make hair prone to dryness and damage. One solution to this concern is to select a mild surfactant. Another approach is to incorporate additives that help replace the removed oils with deposits; however, this approach has proven difficult to implement, especially in rinse-off applications.

[0005] In U.S. Pat. No. 7,067,499, Erazo-Majewicz et al. disclose personal and household care product compositions comprising at least one cationic polygalactomannan or derivative of a cationic polygalactomannan, wherein the derivative moiety on the cationic derivatized polygalactomannan is selected from the group consisting of alkyl, hydroxyalkyl, alkylhydroxyalkyl, and carboxymethyl, where the alkyl has a carbon chain containing 1 to 22 carbons and the hydroxyalkyl is selected from the group consisting of hydroxyethyl, hydroxypropyl, and hydroxybutyl, and the at least one cationic polygalactomannan or derivative of a cationic polygalactomannan has a mean average molecular weight (Mw) with a lower limit of 5,000 and an upper limit of 200,000, has an optical transmittance of greater than 80% at a light wavelength of 600 nm in a 10% aqueous solution, has a protein content of less than 1.0% by weight of the polysaccharide, and has an aldehyde functional group content of at least 0.01 megahertz / gram.

[0006] Conventionally used deposition aids, such as soluble cationically modified cellulose (e.g., polyquaternium-10), guar hydroxypropyltrimonium chloride, and other cationic polymers (e.g., polyquaternium-6, polyquaternium-7), provide a certain level of deposition in personal care detergents, but nevertheless exhibit low efficiency and require the incorporation of relatively high levels of active ingredients into personal care detergent formulations to promote the desired results. However, such high levels of active ingredients (e.g., silicones) adversely affect the foaming / lather feel and cost of the formulations when used by consumers.

[0007] Thus, there remains a need for deposition aids that promote improved efficiency of silicone deposition from hair cleansing formulations.

[0008] The present invention provides a hair cleansing agent comprising a dermatologically acceptable vehicle, a dermatologically acceptable hair care cleansing surfactant, a dermatologically acceptable silicone, and a deposition aid polymer, wherein the deposition aid polymer is a dextran polymer crosslinked with a dextran crosslinker of formula (I):

[0009] [ka] wherein X is a halogen and each R 1 are independently substituted or unsubstituted C 1~6 alkyl groups, and each R 2 independently, C 1~6 The deposition aid polymer is selected from the group consisting of alkanediyl groups, and Y is a divalent bridging group, which enhances the deposition of dermatologically acceptable silicone from the hair cleanser onto mammalian hair.

[0010] The present invention provides a method for cleansing mammalian hair and simultaneously depositing silicone on the mammalian hair, the method comprising selecting a hair cleanser of the present invention and applying the hair cleanser to the mammalian hair.

[0043] Some embodiments of the present invention are described in detail in the following examples.

[0044] Example S1: Synthesis of dextran crosslinker Bis[2-(N,N-dimethylamino)ethyl]ether (10.84 g) and water (23.12 g) were mixed together in a vessel. The pH of the vessel contents was adjusted to 8.5 with concentrated hydrochloric acid. 99.9% epichlorohydrin (20.84 g) was added to the vessel over 60 minutes while maintaining the vessel contents' set-point temperature at 25°C. After maintaining the vessel contents' set-point temperature at 25°C for an additional 2 hours, the set-point temperature was increased to 50°C and maintained at that temperature set-point for 2 hours. The pH of the vessel contents was then reduced to <2.0 with concentrated hydrochloric acid, and the set-point temperature was increased to 70°C and maintained at that temperature set-point for 1 hour. The vessel contents were then cooled. After the vessel contents' temperature had decreased below 50°C, the pH of the vessel contents was adjusted to 4-6 with 50% sodium hydroxide solution. The vessel contents were then extracted seven times (1 vol:1 vol) with methylene chloride, after which the residual methylene chloride was removed by conventional methods. The recovered material contained 39.4% by weight of product solids. 13 Analysis by C NMR showed that the product

[0045] [ka] The compound was identified as N,N'-(oxybis(ethane-2,1-diyl))bis(3-chloro-2-hydroxy-N,N-dimethylpropan-1-aminium) chloride.

[0046] Example S2: Synthesis of cross-linked dextran polymer Dextran (23.23 g; Aldrich product number D4876) and deionized water (120 g) were added to a 500 mL four-neck round-bottom flask equipped with a rubber ceramic cap, a nitrogen inlet, a pressure-equalizing addition funnel, a stirring paddle and motor, a subsurface thermocouple connected to a J-KEM controller, and a Friedrich condenser connected to a mineral oil bubbler. The weight-average molecular weight of the dextran was 100,000-200,000 daltons. While stirring the contents, the apparatus was purged with nitrogen to displace any oxygen trapped in the system. The nitrogen flow rate was approximately 1 bubble per second. The mixture was stirred for 1 hour while purging with nitrogen. Using a plastic syringe, 50% aqueous sodium hydroxide (14.9 g) was added to the flask contents over several minutes while stirring under nitrogen. The flask contents were then stirred under nitrogen for 30 minutes. A 47% aqueous solution (74.45 g) of dextran crosslinker prepared according to Example S1 was then added to the flask contents and stirred for 5 minutes before heating. Heat was then applied to the flask contents with a heating mantle controlled using a J-KEM controller set at 55°C. The flask contents were heated to 55°C and maintained for 90 minutes. The flask contents were then cooled to room temperature while maintaining positive nitrogen pressure within the flask. Once the flask contents reached room temperature, the flask contents were neutralized by adding glacial acetic acid (3.0 g), and the flask contents were stirred for 10 minutes. The flask contents were then diluted and transferred for use without further purification; the diluted product solids content was 11.1 wt%. An aliquot of the solution was precipitated from methanol and dried under reduced pressure at 50°C. The total Kjeldahl nitrogen content (TKN) of the dried precipitate was measured as 2.72 wt% using a Buchi KjelMaster K-375 automated analyzer.

[0047] Comparative Examples CF1-CF3 and Example F1: Hair Cleansing Formulation Hair wash formulations were prepared using the general hair wash formulations set forth in Table 1 for each of Comparative Examples CF1-CF3 and Example F1.

[0048] [Table 1]

[0049] The hair wash formulations for each of Comparative Examples CF1-CF3 and Example F1 were prepared using the following process: In a container, a 30 wt% aqueous solution of sodium lauryl sulfate was dissolved in deionized water and heated to 70°C with constant stirring. The polymers listed in Table 1 were then added to the container with stirring (i.e., polyquaternium-10, guar hydroxypropyltrimonium chloride, unmodified branched dextran, and cross-linked dextran prepared according to Example S2). Once the polymers were dissolved, tetrasodium EDTS was then added to the container. Once the contents of the container reached 70°C, a 45 wt% aqueous solution of PEG-150 pentaerythrityl tetrastearate and a 30 wt% aqueous solution of cocamide MEA were added to the container. A 30 wt% solution of cocamidopropyl betaine was then added to the container. The contents of the container were then allowed to cool. Once at room temperature, phenoxyethanol and methylisothiazolinone preservatives, and a 50% by weight solids aqueous emulsion of dimethiconol and TEA-dodecylbenzenesulfonate were added to the container. The final pH of the product shampoo formulation was then adjusted to pH 5.5 using citric acid, if necessary, and sufficient water was added to bring the total weight of the formulation to 100 g.

[0050] Silicone Deposition Analysis Silicone deposition onto hair from hair wash formulations prepared according to Comparative Examples CF1-CF3 and Example F1 was quantified using X-ray photoelectron spectroscopy (XPS), which provides quantitative elemental and chemical state information from the top 10 nm of the hair sample.

[0051] Hair tresses (2 g, European Virgin Brown, available from International Hair Importers) were first washed with a 9 wt. % sodium laureth sulfate (SLES) solution and rinsed with water flowing at 0.4 L / min for 60 seconds. After the initial washing step, the tresses were then washed with the hair wash formulations of Comparative Examples CF1-CF3 and Example F1 by applying 0.8 g of the hair wash formulation to the tress, massaging on both sides for 30 seconds, and then rinsing with water flowing at 0.4 L / min for 60 seconds. The hair tresses were then evaluated using XPS. XPS data was obtained from 1 cm 2 Measurements were taken from four areas per tress over a range of 100-150°C. The instrument parameters used are provided in Table 2. The mole % of silicon from the hair wash formulation deposited on the hair is reported in Table 3.
