preparation example Construction

[0044] In the preparation of the emulsion, surfactants and water are used. As the surfactant, any one of anionic surfactants, cationic surfactants, nonionic surfactants and amphoteric surfactants may be used alone or as a mixture of two or more.

[0045] Examples of anionic surfactants include dodecylbenzenesulfonic acid, octylbenzenesulfonic acid, polyoxyethylene lauryl sulfate, lauryl sulfate, tetradecenesulfonic acid, hydroxytetradecene Sulfonic acids, and their sodium salts, potassium salts, triethanolamine salts, etc.

[0046] Examples of cationic surfactants include lauryl trimethyl ammonium hydroxide, stearyl trimethyl ammonium hydroxide, dioctyl dimethyl ammonium hydroxide, distearyl dimethyl ammonium hydroxide, lauryl trimethyl ammonium hydroxide, Methylammonium Chloride, Stearyltrimonium Chloride, Cetyltrimonium Chloride, Dicocodimonium Chloride, Distearyldimonium Chloride, Chlorine Benzyl ammonium chloride, stearyl dimethyl benzyl ammonium chloride, and the like. ...

Embodiment

[0065] Emulsion of aminosilicone 1 (E1):

[0066] Aminosiloxane modified at both ends is represented by formula I, wherein x=650, y=3.5, R 1 is an alkyl group containing 16 to 18 carbon atoms, R 2 is methyl, R 3 is N-(2-aminoethyl)-3-aminopropyl.

[0067] The aminosilicone was emulsified with Tergitol TMN-6, a nonionic surfactant available from Dow.

[0068] 100 g of the emulsion were prepared according to the following protocol. 20 g of aminosilicone and 12 g of Tergitol™ N-6 were mixed in a flask equipped with a high shear paddle at 800 rpm while heating the mixture to 65°C. After obtaining a homogeneous blend, 10 g of deionized water was added slowly under shear. Acetic acid was slowly added. Immediately add the remaining water while mixing under high shear. The flask was removed from the heat and the emulsion mixed by shearing for an additional 30 minutes. A transparent microemulsion was obtained.

[0069] Emulsion of aminosilicone 2 (E2):

[0070] Aminosiloxan...

Abstract

There is provided herein a method of treating thermally and / or chemically damaged including the following steps: contacting thermally and / or chemically damaged Ii air with a hair treating composition comprising a aminosilicone of the general formula (I): MDxD'yM (I) wherein: M = R1R2 2SiO1 / 2 D = R2 2Si02 / 2, and D' = R2R3SiO2 / 2, and where R1 is an alkyl group having 12 to 50 carbon atoms, R2 is a substituted or un- substituted hydrocarbon group having 1 to about 6 carbon atoms, R3 is 3-aminopropyl group and / or a N-(2-aminoethy])-3-aminopropyl group, x has a value of 1 to about 2,000, and y has a value of 1 to about 50.

Description

technical field [0001] The present invention relates to a method of treating hair using a hair treatment composition, in particular a silicone hair treatment composition, which method imparts excellent thermal protection and lubrication properties to the hair, which makes the hair shiny and non-greasy. Background technique [0002] Hair is thermally damaged during drying of the hair, such as repeated blow dryer actions, and during curling or straightening of the hair with flat irons. The thermal damage is enhanced in the presence of moisture and tensile stress which cause distortion of the hair cuticle. Wrinkling of the cuticle makes the hair duller and smoother to the touch. [0003] The surface of virgin hair is hydrophobic and less susceptible to heat damage than bleached hair (which is usually hydrophilic). It is also desirable to restore the hydrophobicity of the hair (which can tolerate multiple wash cycles) to help protect the hair when heated in the presence of moi...
