Problems solved by technology

However, perfluoropolyether has a high density and extremely low surface tension, and it is difficult to form a stable emulsion directly with the water system, which greatly limits the application of perfluoropolyether in cosmetics
In the previous literature or patents, similar perfluoropolyether emulsion compositions were studied. However, these perfluoropolyether emulsion compositions are not stable after being mixed with cosmetic compositions, and it is difficult to meet the needs of practical applications.

Abstract

The present invention discloses a perfluoropolyether emulsion composition and a preparation method thereof, wherein polyol, fluorintaed alcohol, water and an auxiliary agent are utilized to prepare a stable perfluoropolyether emulsion composition, and the perfluoropolyether emulsion composition comprises 10-80 wt% of perfluoropolyether. The perfluoropolyether emulsion composition can be uniformly mixed with a variety of emulsions and pastes.

Description

technical field [0001] The invention relates to a stable emulsion formed by perfluoropolyether oil, polyhydric alcohol and water. The emulsion can be easily mixed with various emulsions and pastes to form stable emulsions and pastes containing perfluoropolyether. Background technique [0002] Perfluoropolyether is a unique liquid material, colorless, odorless, non-toxic, non-irritating, with excellent hand feeling, good chemical environment stability, low viscosity, excellent film-forming properties, so It can be well applied to the field of cosmetics. At the 14th International Federation of Cosmetic Chemists' Societies Conference held in Barcelona in 1986, perfluoropolyether was first approved by the conference delegates as an additive in cosmetics. The function of perfluoropolyether is that it can form a thin protective film to prevent the corrosion of various harmful substances, and perfluoropolyether has a strong oxygen dissolving ability, which can enhance the oxygen c...
