Pregnenolone Acetate
What is Pregnenolone Acetate?
Pregnenolone Acetate is a lipophilic ester derivative of pregnenolone, a naturally occurring C21 steroid alcohol that acts as a biosynthetic precursor to progesterone, corticosteroids, and androgens in human physiology. Synthesized for stability and solubility, it belongs to the pregnane class of compounds with a characteristic steroid backbone and acetate moiety at the 3-position. In cosmetic products like creams and lotions, it serves in the skin conditioning category. It functions by depositing a thin emollient layer on the skin surface, aiding moisture retention and enhancing the barrier to promote suppleness. This interaction with cutaneous lipids helps mitigate roughness, fostering a smoother feel without altering deeper structures. Commercial use draws from its biochemical similarity to endogenous compounds, optimized for topical delivery in low amounts.
