Esters

What Esters is & what it does

Esters are a broad chemical class formed by reacting an acid with an alcohol, and on cosmetic labels the generic term usually points to a blend of emollient ester oils. In formulas they spread easily and give a light, silky slip, softening skin and helping other ingredients glaze evenly over the surface. Ester emollients are a workhorse of sunscreen and moisturizer textures because they can dissolve oil-soluble UV filters and cut greasiness. The exact feel depends on which specific esters are used.

What do esters do in sunscreen?

In sunscreen, ester emollients help spread the product smoothly, dissolve oil-soluble UV filters, and cut greasiness for a lighter feel. They are not UV filters themselves, so they support the texture rather than the protection.

Are esters safe in cosmetics?

Cosmetic ester emollients are widely used and generally considered well tolerated. The exact profile depends on which specific esters are in the blend.
