AI Technical Summary

Technical Problem

While existing non-transferable lipsticks maintain a long-lasting, non-transferable finish, they often fail to provide good moisturizing effects and suffer from poor stability.

Method used

By adding polyols and water-in-oil emulsifiers to the all-oil system, an oil-in-alcohol emulsion system is constructed, forming a stable oil-in-alcohol microstructure. The hydrophilic groups of the polyols adsorb moisture from the air to form a water-locking film, and the cohesive strength of the paste is improved by combining wax and filler powder.

Benefits of technology

It achieves a long-lasting, non-sticky finish and provides extended hydration, improving lip dryness, enhancing product stability and firmness, reducing production difficulty, and ensuring color consistency and even makeup application.
