Science
Mechanism of Action
On the skin, Methyl Isostearate functions by forming a conditioning layer that smooths the skin's surface and helps to maintain its moisture balance, keeping it in good condition. As a surfactant and emulsifying agent, it stabilizes oil-in-water mixtures, preventing separation of phases and ensuring a uniform product texture and delivery.

Stability
As an ester, Methyl Isostearate is susceptible to vigorous exothermic reactions when exposed to strong acids, particularly oxidizing ones, and caustic solutions. Interactions with alkali metals or hydrides can lead to the generation of flammable hydrogen. It demonstrates negligible water solubility (0.001354 mg/L at 25 °C) but is highly soluble in various organic solvents, including ethanol (101.1 g/L), ethyl acetate (829.31 g/L), and chloroform (1710.53 g/L).
