AI Technical Summary

Technical Problem

Compositions containing both niacinamide and tranexamic acid suffer from severe crystal precipitation, which can adhere to dispensing nozzles or lids, posing a problem in their use.

Method used

Incorporating mucopolysaccharides and amphiphilic polymers into the formulation suppresses crystal precipitation, specifically using components (A) Niacinamide 1-10% by mass, (B) Tranexamic acid 1-7% by mass, (C) Mucopolysaccharide, and (D) Amphiphilic polymers, with defined mass ratios for optimal effect.

Benefits of technology

The composition effectively inhibits crystallization, providing a stable cosmetic or external preparation for the skin with improved crystal precipitation suppression.
