Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silicone emulsion-based cosmetic raw material, and more particularly, it has excellent storage stability.
The present invention also relates to a silicone emulsion-based cosmetic raw material which has excellent compounding stability with other cosmetics and is suitable as a raw material for hair cosmetics and skin cosmetics.

2. Description of the Related Art Organopolysiloxanes are widely used as raw materials for cosmetics, release agents, fiber treatment agents and the like.
When such an organopolysiloxane is used as a raw material for cosmetics, it is usually used by blending it with other organic cosmetic raw materials such as animal and vegetable oils, mineral oils, hydrocarbon oils, fatty acid esters, waxes and alcohols. For this reason, organopolysiloxanes used in cosmetic raw materials are required to have stable blending or dispersion with other organic cosmetic raw materials and dilution stability of mixed liquids. However,
In general, organopolysiloxane is inferior in compounding stability to other organic cosmetic raw materials, and after compounding, the compounded liquid thickens, creaming occurs in the compounded liquid, and the organopolysiloxane component is removed from the compounded liquid. There has been a problem that separation may occur. For this reason, the organopolysiloxane is previously dispersed in water with a specific emulsifier,
Attempts have been made to improve the stability of blending with other cosmetic ingredients. For example, Japanese Patent Publication No. 58-7335 proposes an emulsion of an organopolysiloxane using sucrose fatty acid ester, sorbitan fatty acid ester and glycerin fatty acid ester as emulsifiers. JP-A-60-126209 proposes an emulsion of an organopolysiloxane using a lipophilic emulsifier and a polyglycerin fatty acid ester as an emulsifier. However, these silicone emulsions are inferior in storage stability and incorporation stability to other cosmetic raw materials, for example, insufficient in terms of dilution stability when diluting the mixture and stability against mechanical share. Met. Further, a silicone emulsion composition using polyoxyethylene alkylphenyl ether phosphoric acid as an emulsifier has been proposed (see JP-A-4-134017). Although this emulsion composition has considerably improved the stability at the time of dilution of the blended liquid, polyoxyethylene alkyl phenyl ether phosphoric acid may cause low molecular weight and re-equilibrium due to the main chain scission of the organopolysiloxane. In addition, there is a problem that the washing ability of polyoxyethylene alkyl phenyl ether phosphoric acid is too strong, so that the effect of improving the feel is reduced, and it is not always satisfactory.

After one month, the silicone emulsion was taken out, and the appearance, nonvolatile content, and viscosity of the silicone component of the silicone emulsion were measured.

Evaluation of feel of hair and improvement in combability of shampoo composition 10 g of a hair bundle having a length of 20 cm was washed with a 2.5 wt% aqueous solution of sodium polyoxyethylene lauryl ether sulfate, and then rinsed with warm water. The hair was dried under a condition of 25 ° C. for 12 hours (hereinafter, the obtained hair is referred to as pre-treated only hair).
This pre-treated hair was immersed in water for 30 seconds, drained, washed with 1 g of the shampoo composition for 1 minute, rinsed twice with warm water for 20 seconds, and then drained, and then at 25 ° C. For 12 hours. For this shampooed hair, the improvement in the feel and combability of the hair was measured. These evaluations were performed by five panelists. In addition, the evaluation of combability was measured as follows. One end of the hair bundle was fixed to a universal tensile tester (manufactured by Tester Sangyo Co., Ltd.), and the maximum value of the tensile force when the hair bundle was moved at a speed of 200 mm / min by passing the hair bundle through a comb of a moving table was read. This was measured for the hair that had only been pre-treated and the hair that had been shampooed, and the combability improvement rate was calculated by the following formula. Combability improvement rate (%) = (tensile force of hair treated only with pretreatment−tensile force of hair treated with shampoo composition) / tensile force of hair treated only with pretreatment ○ Tactile evaluation of hair with hair rinse composition and 10 g of hair bundle having a length of 20 cm was washed with a 2.5% by weight aqueous solution of sodium polyoxyethylene lauryl ether sulfate, rinsed with warm water, and dried at 25 ° C. for 12 hours (hereinafter, the resulting product was obtained). Is called pre-treated only hair).
This pretreated hair was immersed in the hair rinse composition for 1 minute, immersed in warm water for 30 seconds, drained, and dried at 25 ° C. for 12 hours. With respect to the hair treated with the hair rinse composition, the feel of the hair was evaluated, and the improvement in combability was measured.
