Description

STEARIC ACID RSPO

Origin

Stearic Acid RSPO (Roundtable on Sustainable Palm Oil–certified) is a vegetable-derived saturated fatty acid obtained primarily from sustainably sourced palm and palm kernel oils. This ingredient is produced through the fractionation and hydrogenation of natural triglycerides, yielding a high-purity, biodegradable fatty acid. RSPO certification ensures that the palm oil used is ethically harvested under sustainable environmental and social standards, supporting eco-responsible supply chains.

Summary

Stearic Acid RSPO is a versatile structuring and emulsifying agent widely used in cosmetic, skincare, and haircare formulations. It provides excellent thickening, stabilizing, and consistency-enhancing properties in both oil-in-water (O/W) and water-in-oil (W/O) emulsions. Known for its creamy texture and elegant finish, Stearic Acid also acts as an emollient, imparting a smooth, soft feel while reinforcing emulsion stability. Its sustainable RSPO certification makes it an ideal choice for clean, natural, and eco-conscious formulations.
