Although Polyhydroxystearic Acid is a widely used ingredient in skin care, beauty and cosmetic products, very little information is available regarding its properties.

Conditioning shampoo composition free of sulfates and dioxan

The invention relates to a conditioning shampoo composition free of sulfates and dioxan. The conditioning shampoo composition is characterized in that the conditioning shampoo composition comprises 4.5%-15% of an amino acid type anionic surfactant and a thickening composition; the amino acid type anionic surfactant is one of a cocoyl alaninate, a lauroyl glutamate, a cocoyl glycinate, a lauroyl sarcosinate, a methyl cocoyl taurate or a mixture thereof; the above mentioned salts are potassium salts or sodium salts or triethanolamine salts; the thickening composition comprises 0.2-4.0% of glyceryl cocoate, 0.05%-1.00% of trihydroxystearin, 0.05-1.50% of polyhydroxystearic acid and 0.2-3.0% of an acrylic (acrylate) copolymer; and the above percentages are both weight percentages. The conditioning shampoo composition is advantageous in that the conditioning shampoo composition has a viscosity range of 3000-30000 cps and is shown as long flowing deformation; the conditioning shampoo composition can be poured out easily from a container; the conditioning shampoo composition is liable to spread on hair; foams of the conditioning shampoo composition are uniform and comfortable; the conditioning shampoo composition is free of the sulfates and the dioxan, and the conditioning shampoo composition has beneficial effects of safety and little irritation.

External preparations for skin

The present invention is a skin treatment composition that characteristically contains an alkyl benzoate represented by the following general formula (1). This provides a skin treatment composition that gives a refreshing sensation at the time of application and can contain drugs and ultraviolet absorbents in a stable manner. Also, the present invention is a sunblock water-in-oil type emulsified cosmetic characteristically comprising an ester bond product of polyhydroxystearic acid represented by the following general formulas (2) or (3), alkyl benzoate represented by the following general formula (1), and an ultraviolet absorbent.
This provides a sunblock cosmetic consisting of a water-in-oil type emulsified composition that can contain an ultraviolet absorbent in a stable manner and exhibits a superior usability.
(In this formula, R denotes a branched or straight chain alkyl group having 8-15 carbon atoms.)
(In this formula, R1 and R2 denote, independently of each other, a hydrogen atom or a lower alkyl group having 1-6 carbon atoms, a+b denotes an integer 1-30, and m denotes an integer 10-200.)
(In this formula, R1 and R2 denote, independently of each other, a hydrogen atom or a lower alkyl group having 1-6 carbon atoms, a+b denotes an integer 1-30, and n denotes an integer 1-30.)

Polyester dispersing agent and preparation method thereof

The invention discloses a polyester dispersing agent shown as a formula I in the specification, wherein PW is polyethyleneimine residue, W represents the number of amino which is not reacted with phthalic anhydride, and W is greater than 10 but less than 600; m represents the number of amino which is reacted with phthalic anhydride in polyethyleneimine, and m is greater than 1 but less than W; B is poly epsilon-caprolactone, poly 12-hydroxystearic acid or a residue after reaction of poly epsilon-caprolactone and poly 12-hydroxystearic acid; P and B are coupled by an amido bond and Y and B are coupled by an ester bond; Y is a residue R-CO- of stearic acid; n represents the number of ester bonds in B and n is an integer ranging from 4 to 20. A preparation method of the polyester dispersing agent shown as the formula I is characterized by comprising the following steps: 1) carrying out a reaction on phthalic anhydride and polyethyleneimine; 2) introducing poly epsilon-caprolactone or poly 12-hydroxystearic acid or a mixture of the poly epsilon-caprolactone and the poly 12-hydroxystearic acid to form a grafted polyester chain; and 3) blocking by stearic acid to obtain the polyester dispersing agent. The polyester dispersing agent disclosed by the invention is wide in range of solvent polarity, so that the application range of the polyester dispersing agent in organic solvents is effectively expanded.
