Butoxyethanol, also known as 2-butoxyethanol, is a colorless liquid chemical that belongs to the group of glycol ethers. It's widely used as a solvent in cosmetics and personal care products to dissolve oils, greases and other substances. It helps maintain the desired texture and consistency of the product and facilitates the even distribution of active ingredients to ensure their effectiveness in the formulation.
Butoxyethanol is a synthetic chemical compound that's created through chemical processes in laboratories.
Butoxyethanol is generally considered safe and is well-tolerated on most skin, but it may cause skin irritation or sensitization in some people, especially at higher concentrations.
Butoxyethanol is not generally used in skincare products for its direct skincare benefits. Instead, it's primarily used as a solvent or co-solvent in formulas to help dissolve and stabilize various ingredients to improve product texture, consistency and efficacy.
