AI Technical Summary

Technical Problem

In existing oral care compositions, peroxides and pigments are prone to catalytic decomposition when they coexist, leading to product bloating and fading, which affects storage stability and aesthetics.

Method used

Pigment Blue 15, ferrous ferrocyanide, or ammonium ferrous ferrocyanide are used as colorants and encapsulated in a thin film with alkyl cellulose to form a highly compatible oral care composition, thereby improving the stability of peroxides.

Benefits of technology

It significantly reduces the negative impact of pigments on peroxides, improves the storage stability and color retention of products, and avoids problems such as bloating and fading.
