Sucrose Myristate

Sucrose myristate is an ester formed from sucrose (a natural sugar) and myristic acid (a fatty acid). It functions as a hybrid ingredient—part emollient, part emulsifier—which makes it useful in both the texture and stability of skincare products.In formulations, it helps bind water and oil phases together whilst also conditioning the skin surface. It's a gentler alternative to some synthetic surfactants, which is why it appears in products marketed toward sensitive or barrier-conscious consumers.

Sucrose myristate works through two mechanisms. As an emollient, its fatty acid chain adheres to the outer skin layer, reducing transepidermal water loss and creating a smoother surface. As an emulsifier, the sugar portion is water-loving whilst the myristic acid portion is oil-loving, allowing it to bridge incompatible ingredients and stabilise the formula.This dual role means the ingredient can improve both the sensory experience of a product and its ability to deliver active ingredients effectively.

Sucrose myristate is typically incorporated into finished products by manufacturers rather than used as a standalone ingredient by consumers. If using a product containing it, apply as directed on the label. It works well in both morning and evening routines and combines readily with most other skincare ingredients, though patch testing is always sensible when introducing any new product.

Sucrose myristate is generally well-tolerated and considered safe for cosmetic use across skin types. Allergic contact dermatitis is rare but possible; discontinue use if irritation develops.
