What Silybum Marianum Ethyl Ester is & what it does
Silybum Marianum Ethyl Ester is an ester derived from milk thistle (Silybum marianum), typically by reacting the plant's fatty acids with ethanol. In cosmetic and sunscreen formulas an ethyl ester of this kind is used as an emollient and skin-conditioning agent that improves spreadability and skin feel. Milk thistle is notable for its silymarin-related antioxidant compounds.
What does Silybum Marianum Ethyl Ester do in skincare?
Silybum Marianum Ethyl Ester, derived from milk thistle, is used as an emollient and skin-conditioning agent. It helps improve spreadability and leaves a softer skin feel, and milk thistle is also associated with antioxidant compounds. It is a supportive ingredient rather than a sunscreen filter.
Is Silybum Marianum Ethyl Ester comedogenic or does it clog pores?
Specific comedogenic data for this milk thistle ester is limited. As a lipid-based emollient it could feel rich on the skin, but its effect on pores depends on the overall formula and your skin type. If you are acne-prone, monitoring how a product suits you is advisable.
Is Silybum Marianum Ethyl Ester natural or synthetic?
It is best described as plant-derived but processed. It starts from milk thistle (Silybum marianum) and is converted into an ethyl ester through a chemical reaction with ethanol. The plant origin means it is generally suitable for vegan formulations.
