What Is Hydrogenated Phosphatidylcholine?
Hydrogenated phosphatidylcholine is used as an emulsifier, emollient, and hydrating agent in cosmetic formulas. Research has also shown hydrogenated phosphatidylcholine can be used as a liposome to help enhance the penetration of other skin care ingredients. Additionally, studies indicate this ingredient offers properties that help support skin’s barrier.
Phosphatidylcholine is the active ingredient in lecithin. The hydrogenated form is noted as having an affinity for skin due to its similar lipid properties that mimic the outermost layer of the epidermis.
Hydrogenated phosphatidylcholine was evaluated by the Cosmetic Ingredient Review Expert Panel in 2020. Their safety assessment noted no qualms with its cosmetic use. It may be synthetic or animal-derived; uses the former.
