Stearyl Citrate

What is Stearyl Citrate?

Stearyl Citrate is a diester compound produced from citric acid, a naturally occurring tricarboxylic acid, and stearyl alcohol, a long-chain fatty alcohol derived from stearic acid found in vegetable fats. It falls into the emollient and skin conditioning category for cosmetics, appearing in moisturizers, lotions, creams, and lip care products. Functionally, it lubricates the skin's surface, reducing friction and filling minor irregularities for a smoother feel. This action enhances product application and spreadability while mimicking natural skin lipids to bolster the barrier against moisture evaporation, especially alongside occlusive agents. Its lightweight profile avoids heaviness, making it versatile for daily use across various formulations.
