Conditioning shampoo composition free of sulfates and dioxan

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of shampoo cosmetics, in particular to a conditioning shampoo composition free of sulfate and dioxane. Background technique [0002] Conditioning shampoos that clean the hair and have a certain after-wash conditioning performance are the mainstream in the market. These products mostly use anionic surfactants such as sodium lauryl polyether sulfate (ammonium) and sodium lauryl sulfate. The main cleaning and foaming ingredients, because this kind of surfactant has good cleaning power and foam, and low cost, it has been widely used at present. However, this anionic surfactant with a sulfate structure has the disadvantages of strong degreasing power and relatively large irritation to the scalp and hair. Some sensitive people will have itchy scalp after washing and the phenomenon of too dry hair. If it is dyed and permed hair, use this kind of shampoo with strong degreasing power, and the color of permed hair wi...

Problems solved by technology

However, there is a difficult problem in the system using amino acid anionic surfactant, that is, it is very difficult to thicken

Among the existing thickening materials, polymer thickeners are sensitive to salts, are not efficient, are not economical, and have a bad feeling of use. If only amino acid-based anionic surfactants are used in conditioning shampoos Using a polymer type thickener, when the desired minimum viscosity of the conditioning shampoo is 3000cps, the product will appear as a jelly that is not easy to open. If you pursue a higher viscosity conditioning shampoo, the jelly situation will be more serious, and the feeling of use will be greatly reduced. ; If some other hydrophilic polyethylene glycol thickeners are compounded, they will contain a certain amount of ethylene oxide groups, which cannot avoid the risk of dioxane, and it is easy to appear in a jelly state in winter and is not easy to squeeze out of the container out
