Hydrogenated Soybean Oil

What is Hydrogenated Soybean Oil?

Hydrogenated soybean oil originates from soybean plants, where the natural oil undergoes hydrogenation—a process that adds hydrogen to unsaturated fatty acids, creating a more saturated, solid fat stable against oxidation and rancidity. This makes it ideal for cosmetics like moisturizers, lip products, and creams. In formulations, it acts by depositing a protective layer on the skin surface to reduce water evaporation, while its fatty acid profile closely resembles human sebum for better compatibility. It also modifies product consistency for smoother application and even distribution, and draws moisture to the skin's outer layer. Commonly found in emollient-rich products, it enhances overall sensory feel without greasiness.
