Science

Mechanism of Action

This seed butter functions primarily by forming a protective, occlusive barrier on the skin's surface, which significantly reduces transepidermal water loss (TEWL) and locks in moisture. Its rich composition of fatty acids—including stearic, oleic, palmitic, and linoleic acids—along with triglycerides, deeply nourishes the skin. Furthermore, it contains natural antioxidants such as Vitamin E, contributing to skin repair, promoting elasticity, and aiding in the prevention of cellular degeneration and wrinkle formation.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

In 2010, the CIR Expert Panel issued an 'Insufficient Data Announcement' for 'Plant-Derived Edible Oils,' including Shorea Stenoptera Seed Oil, due to incomplete fatty acid profiles within the broader group. However, Shorea Stenoptera Seed Butter itself is generally regarded as safe for topical use in cosmetics. It is typically non-comedogenic, not classified as dangerous under EC 1272/2008, and exempt from restrictions under Regulation (EC) No 1223/2009. It is well-tolerated across most skin types, though a patch test is advisable for individuals with heightened sensitivities.
