Description
» J3878 (C) CPL wn
The present invention is directed to a hair relaxing composition and a method of relaxing hair. 3 .
Hair relaxers are compositions used to relax or straighten curly or kinky hair. Most hair relaxers straighten hair by disrupting disulfide bonds of the hair fibres with an “alkaline agent or reducing agent. The chemical disruption of disulfide bonds is usually combined with mechanical straightening of the hair (eg by combing). The straightening ~ process is generally terminated by rinsing and/or the : application of a neutralizing composition.
A source of hydroxide ions is usually the preferred alkaline agent used to straighten hair. The term "lanthionizing" is used when referring to hair relaxed or straightened by hydroxide ions, as the straightening reaction sequence with hydroxide ions results in lanthionine residue formation. ~ _ i ~~ Most frequently, commercial relaxing compositions are : in the form of gels or emulsions and contain varying } proportions of strong water- soluble bases, such as sodium hydroxide (NaOH). Also used are slightly-soluble metal . hydroxides, such as calcium hydroxide (Ca(OH).), which can be converted in situ to soluble bases, such as guanidine ’ hydroxide. oo - Hair relaxers leave the hair treated therewith feeling rough, unconditioned and brittle. The present invention
. J3878 (C) CPL
R -2- relates to hair relaxing systems which leave the hair less prone to breakage and feeling smooth.
In one aspect the present invention relates to a method for relaxing hair comprising the following steps: oo i). applying to the hair for a sufficient period of : time to lanthionize the hair a relaxer ‘composition; + ii) terminating the lanthionization process; iii) applying to the lanthionized hair a post- : lanthionization composition comprising a mono : glyceride having an C16 to C22 alkyl ester group. -
A further aspect of the invention is the use of a mono glyceride having an Cl6 to C22 alkyl ester group a post-treatment composition for decreasing hair breakage.
As disclosed above the present invention relates to post-. treatment composition for application after application of a : relaxing composition. In the context of the present invention "relaxing composition” means a composition So Co comprising at least one hydroxide ion generator in an amount sufficient to effect lanthionization of keratin fibres. The : term post-treatment refers to a treatment applied to the 3 hair after the lathionization process, and preferably after any subsequent termination process. :
The hydroxide ion generator may be chosen from those : compositions that produce hydroxide ions appropriate for the lanthionization of hair. As used herein, "hydroxide ion generator" refers to both compounds and compositions that
. J3878 (C) CPL - 3 = generate hydroxide ions, and compounds and compositions that comprise hydroxide ions. Hydroxide ion generators may, for example, be chosen from traditional "lye" and "no lye" hair relaxer compositions and other soluble or slightly soluble hydroxide ion sources. Preferably, the hydroxide ion is ~ generated in situ. Preferred hydroxide ion generators are’ strong water- soluble bases, particularly preferred is sodium hydroxide. :
The post lanthionization composition comprises a : monoglyceride having an C16 to C22 alkyl ester group. . Preferably the mono glyceride comprises a long chain oo unsaturated group, and is more preferably glyceryl oo 15 monololeate. SE "The level of monoglyceride within the post-treatment composition is preferably from 1 to 10 wt%, more preferably from 3.5 to 7.5 wt% of the total composition. oo
The post treatment composition will preferably comprise one ’ or more conditioning surfactants which are cosmetically . . acceptable and suitable for topical application to the hair.
Suitable conditioning surfactants are selected from cationic surfactants, used singly or in admixture.
Cationic surfactants useful in compositions of the invention : contain amino or quaternary ammonium hydrophilic moieties ‘which are positively charged when dissolved in the aqueous composition of the present invention.
. J3878 (C) CPL .
Examples of suitable cationic surfactants are those corresponding ‘to the general formula: [N(R1) (Rg) (R3) (Rg) ]™ (X)°7
E 5 in which Ri, R;, Rs, and Ry; are independently selected from (a) an aliphatic group of from 1 to 22 carbon atoms, or (b) an aromatic, alkoxy, polyoxyalkylene, alkylamido, : hydroxyalkyl, aryl or alkylaryl group having up to 22 carbon atoms; and X is a salt-forming anion such as those selected from halogen, (e.g. chloride, bromide), acetate, citrate, ‘ lactate, glycolate, phosphate nitrate, sulphate, and : alkylsulphate radicals. ~ :
The aliphatic groups can contain, in addition to carbon and hydrogen atoms, ether linkages, and other groups such as amino groups. The longer chain aliphatic groups, e.g., those of about 12 carbons, or higher, can be saturated or unsaturated.
The most preferred cationic surfactants for conditioner compositions of the present invention are monoalkyl quaternary ammonium compounds in which the alkyl chain length is C8 to Cl4.
Suitable examples of such materials correspond to the general formula: : [N(Rs) (Re) (R7) (Rg) 1" (X)~
. J3878 (C) CPL in which Rs is a hydrocarbyl chain having 8 to 14 carbon atoms or a functionalised hydrocarbyl chain with 8 to 14 : carbon atoms and containing ether, ester, amido or amino moieties present as substituents or as linkages in the radical chain, and Rg, Ry and Rg are independently selected
Co from (a) hydrocarbyl chains of from 1 to about 4 carbon atoms, or (b) functionalised hydrocarbyl chains having from 1 to about 4 carbon atoms and containing one or more : aromatic, ether, ester, amido or amino moieties present as substituents or as linkages in the radical chain, and X is a salt-forming anion such as those selected from halogen, . (e.g. chloride, bromide), acetate; citrate, lactate, glycolate, phosphate nitrate, sulphate, and alkylsulphate " radicals. : : ) | | oo
The functionalised hydrocarbyl chains (b) may suitably contain one or more hydrophilic moieties selected from alkoxy (preferably C; — C3 alkoxy), polyoxyalkylene (preferably C; = C3; polyoxyalkylene), alkylamido, hydroxyalkyl, alkylester, and combinations thereof.
Preferably the hydrocarbyl chains R; have 12 to 14 carbon atoms, most preferably 12 carbon atoms. They may be derived from source Qils which contain substantial amounts of fatty acids having the desired hydrocarbyl chain length. For : example, the fatty acids from palm kernel oil or coconut oil can be used as a source of C8 to C12 hydrocarbyl chains. : Typical monoalkyl quaternary ammonium compounds of the above general formula for use in shampoo compositions of the invention include: | :

In the conditioners of the invention, the level of cationic surfactant is preferably from 0.01 to 10, more preferably 0.05 to 7, most preferably 0.5 to 5 wt% of the total Co : composition. og . -
The weight ratio of cationic conditioning agent to : monoglyceride within the post-treatment composition is preferably from 1:10 to 10:1, more preferably from 1:5 to. 5:1.
. J3878 (C) CPL . Cg
Post treatment compositions of the invention preferably : additionally comprise a fatty alcohol material. The combined use of fatty alcohol materials and cationic surfactants in conditioning compositions is believed to be especially advantageous, because this leads to the formation of a lamellar phase, in which the cationic surfactant is dispersed.
By “fatty alcohol material” is meant a fatty alcohol, an : alkoxylated fatty alcohol, or a mixture thereof. : Representative fatty alcohols comprise from 8 to 22 carbon atoms, more preferably 16 to 20. Examples of suitable fatty alcohols include cetyl alcohol, stearyl alcohol and mixtures : thereof. The use of these materials is also advantageous in that they contribute to the overall conditioning properties of compositions of the invention. : ~ Alkoxylated, (e.g. ethoxylated or propoxylated) fatty alcohols having from about 12 to about 18 carbon atoms in the alkyl chain can be used in place of, or in addition to, oo the fatty alcohols themselves. Suitable examples include oo ethylene glycol cetyl ether, polyoxyethylene (2) stearyl ether, polyoxyethylene (4) cetyl ether, and mixtures : thereof. :
The level of fatty alcohol material in conditioners of the invention is suitably from 0.01 to 15, preferably from 0.1 to 10, and more preferably from 0.1 to 5 wt%. The weight ratio of cationic surfactant to fatty alcohol is suitably
. J3878 (C) CPL from 10:1 to 1:10, preferably from 4:1 to 1:8, optimally from 1:1 to 1:7, for example 1:3. :
Post treatment compositions of the invention can also contain a cationic polymer. :
The compositions of the invention can contain, emulsified droplets of a silicone conditioning: agent, for enhancing ++ - conditioning performance. The silicone is insoluble in the aqueous matrix of the composition and so is present in an . emulsified form, with the silicone present as dispersed droplets. : Co
Lo Suitable silicones include polydiorganosiloxanes, in particular polydimethylsiloxanes which have the CTFA designation dimethicone. Also suitable for use compositions of the invention (particularly shampoos and conditioners) are polydimethyl siloxanes having hydroxyl end groups, which have the CTFA designation dimethiconol. Also suitable for use in compositions of the invention are silicone gums having a slight degree of cross-linking, as are described oo for example in WO 96/31188. "These materials can impart : body, volume and stylability to hair, as well as good wet and dry conditioning. oo | | | | | I
The viscosity of the emulsified silicone itself (not the emulsion or the final hair conditioning composition) is : typically at least 10,000 cst. In general we have found that conditioning performance increases with increased viscosity. Accordingly, the viscosity of the silicone itself is preferably at least 60,000 cst, most preferably at
. J3878 (C) CPL least 500,000 cst, ideally at least 1,000,000 cst.
Preferably the viscosity does not exceed 10° cst for ease of formulation. : :
Emulsified silicones for use .in the shampoo compositions of the invention will typically have an average silicone droplet size in the composition of less than 30, preferably less than 20, more preferably less than 10 pum. We have _ found that reducing the droplet size generally improves conditioning performance. Most preferably the average silicone droplet size of the emulsified silicone in the composition is less than 2 pum, ideally it ranges from 0.01 to 1 um. Silicone emulsions having an average silicone droplet size of < 0.15 pm are generally termed microemulsions. Co .
Suitable silicone emulsions for use in the invention are also commercially available in a pre-emulsified form.
Examples of suitable pre-formed emulsions include emulsions
DC2-1766, DC2-1784, and microemulsions DC2-1865 and :
DC2-1870, all available from Dow Corning. These are all emulsions/microemulsions of dimethiconol. Cross-linked silicone gums are also available in a pre-—-emulsified form, which is advantageous for ease of formulation. A preferred - example is the material available from Dow Corning as DC X2- 1787, which is an emulsion of cross-linked dimethiconol gum. : A further preferred example is the material available from } Dow Corning as DC X2-1391, which is a microemulsion of cross-linked dimethiconol gum.
