Science
Mechanism of Action
Functioning primarily as an emulsifying surfactant, Dextrin Myristate effectively reduces the interfacial tension between immiscible substances like oil and water, enabling them to form stable, homogenous emulsions. On the skin's surface, it forms a delicate film on the stratum corneum, enhancing moisture retention and providing a smooth, non-tacky after-feel. As a derivative of hyperbranched dextrin, it also offers potential soothing and protective benefits, aligning with microbiome-friendly principles.

Formulation
Stability
Dextrin Myristate exhibits robust solubility in organic solvents such as xylene, benzene, chloroform, and carbon tetrachloride, confirming its oil-soluble nature. It is notably insoluble in water, methanol, and ethanol. While specific optimal pH ranges for its stability are not defined, the general dextrin component may degrade in alkaline environments, with α-amylase enzyme activity (which can degrade dextrin) optimal at pH 6.7-7.0, suggesting consideration for pH in highly alkaline formulations.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Dextrin Myristate as safe for use in cosmetic applications. Comprehensive animal studies demonstrated no skin irritation in rabbits and no skin sensitization in guinea pigs. Furthermore, dextrin, its base component, is recognized as Generally Recognized As Safe (GRAS) by the FDA for food applications.
