Embodiment

[0010] A typical shampoo formula is compared with a product added with α-carboxy long-chain alkyl dimethyl amine oxide, and the specific implementation ratio is as follows.

[0011] Typical shampoo mass percentage content: sodium lauryl sulfate 15%, sodium fatty alcohol polyoxyethylene ether sulfate 15%, polyquaternium-47 content 4%, ammonium chloride 1%, methyl paraben 1%, and the pH was adjusted to 6.4.

[0012] Control formula: 20% sodium lauryl sulfate, 3% α-tetradecyl long-chain alkyl dimethyl amine oxide, 4% polyquaternium-47, and adjust the pH to 6.3.

[0013] Comparing the two products, there is no significant difference in appearance, and the irritation of the control formula product is obviously improved, and the foam is delicate, rich and stable.

Abstract

The invention discloses an application of alpha-carboxyl long-chain alkyl dimethyl amine oxide in hairdressing hair-care products. An ampholytic surfactant, namely, alpha-carboxyl long-chain alkyl dimethyl amine oxide has compatibility with various surface active agents, not only can effectively reduce the irritation of an anionic surfactant in formula and has fine and abundant foams but also can acquire a shearing diluted rheological behavior and has a sterilizing function. After the alpha-carboxyl long-chain alkyl dimethyl amine oxide is added into the hair shampoo, the dosage of the preservative can be greatly reduced and the tenderness of the product is promoted; the comfortable sensation can be enhanced; the damaged hair can be quickly repaired and can become softer and glossier.

Description

technical field [0001] The invention belongs to the field of daily chemical technology, and in particular relates to the application of α-carboxy long-chain alkyl dimethyl amine oxide in shampoo and hair care products. Background technique [0002] In shampoo and hair care products, in order to achieve the ideal decontamination effect, the surfactant content is generally not less than 15%. Traditional surfactants are irritating and sensitizing to skin and mucous membranes, and have the disadvantages of being too strong in degreasing and irritating to a certain extent. Many products currently on the market are relieved by adding various natural extracts and traditional Chinese medicine extracts, but they need to add an appropriate amount of preservatives to prevent the growth of microorganisms, and most preservatives have potential risks to human health. Therefore, the tensio-active agent of developing mildness is still the main way of producing green non-irritating high-gra...
