Methyl Glucose Sesquistearate

Methyl Glucose Sesquistearate Description

Methyl glucose sesquistearate is a mixture of the di-esters of simple sugar methyl glucoside and the fatty acid stearic acid. It’s vegetable-derived and is supplied to cosmetics companies as off-white flakes. In skin care products it functions as a skin-softening ingredient as well as an emollient (moisturizer).

When used as an emulsifier (an ingredient that keeps unlike substances like oil and water from separating), it helps stabilize product texture, contribute to how lather in cleansers feels, and enhances product appearance.

The Cosmetics Ingredient Review Panel has determined that methyl glucose sesquistearate is safe as used in skin care and hair care products. Their assessment cited research that found even in amounts up to 100%, methyl glucose sesquistearate did not irritate skin.
