Hydrogenated Lecithin

Hydrogenated lecithin is a phospholipid that is produced by controlled hydrogenation of the skin-restoring ingredient lecithin. It can be manufactured synthetically or may be derived from animals (egg yolk is a source) or plants. Reported functions of hydrogenated lecithin in skin care and other personal care formulations include dispersing agent, skin-conditioning emollient, and emulsifier. As with other phospholipids, research shows it can enhance the penetration of other skin care ingredients in a formulation for greater efficacy. It is used in advanced active ingredient dlivery systems like liposomes and micelles, which improve adsorption and penetration through the skin’s lipid barrier. As a raw material, the appearance of hydrogenated lecithin can vary depending on the source. Descriptions range from a white to beige-gray powder appearance. According to the Cosmetic Ingredient Review (CIR) Expert Panel’s 2020 safety assessment, the maximum reported concentration of use was 5% (for face and neck products). Any amount 15% or below was deemed safe for rinse-off and leave-on products. The CIR Expert Panel concluded that the safety data is insufficient for products containing hydrogenated lecithin that may be inhaled (such as sprays). As such, it is uncommon to find this ingredient in those types of products.
