AI Technical Summary

Technical Problem

In the prior art, the self-thickening gel formation of N-long-chain acyl amino acids and basic amino acids/inorganic bases requires a high content, resulting in high cost and limited use in cosmetics. Furthermore, the low natural source index of betaine limits the natural source content of the formulation.

Method used

A gel is formed by increasing the amount of salts of N-long-chain acyl amino acids and unneutralized free N-long-chain acyl amino acids, and by adding a specific type of hydrophilic nonionic surfactant, such as PEG-150 pentaerythritol tetrafatty acid ester.

Benefits of technology

A highly efficient gel was formed without relying on betaine, increasing the natural source content of the formula, and the amount of N-long-chain acyl amino acids used did not exceed the cosmetic limit, achieving low-cost gel formation.
