Cetostearyl alcohol is widely used in the cosmetic and pharmaceutical industries due to its emulsifying, stabilizing, and thickening properties. In skincare products, it acts as an emollient, helping to soften and smooth the skin by forming a protective barrier that retains moisture. It is commonly found in creams, lotions, and ointments, where it enhances texture and improves spreadability.

In hair care products, it conditions and adds shine to hair, making it a key ingredient in conditioners and styling creams. Its ability to stabilize formulations makes it valuable in pharmaceutical preparations, such as topical creams and ointments, where it ensures consistent product performance. Additionally, it is used in the production of suppositories and as a lubricant in tablet manufacturing. Its versatility and safety profile make it a popular choice in a wide range of personal care and medical applications.
