Ethylhexylglycerin is a synthetic compound commonly used in cosmetics and personal care products. It acts as a skin-conditioning agent and a preservative, helping to enhance the texture and feel of products while also extending their shelf life. This ingredient is often found in lotions, creams, and serums due to its moisturizing properties. It is considered safe for use in cosmetics and is well-tolerated by most skin types, making it a popular choice for formulators looking to improve product performance without irritating the skin.
