Preparation of Cetyl alcohol: With the demise of commercial whaling, cetyl alcohol is no longer primarily produced from whale oil but instead either as an end-product of the petroleum industry, or produced from vegetable oils such as palm oil and coconut oil.

Uses of Cetyl alcohol: it is used in the cosmetic industry as a surfactant in shampoos, or as an emollient, emulsifier or thickening agent in the manufacture of skin creams and lotions. It is also employed as a lubricant for nuts and bolts.

When you are using this chemical, please be cautious about it as the following:
This chemical may cause inflammation to the skin or other mucous membranes. It is irritating to eyes, respiratory system and skin. You should not breathe its dust. What's more, you must avoid contact with skin and eyes. Whenever you will contact it, please wear suitable gloves.

You can still convert the following datas into molecular structure:
