- n. An alcoholic radical (C16H33) supposed to exist in a series of compounds obtained from spermaceti and beeswax.
Thus the fat or oil of dozens of different nuts and plant-products and of lower animals and fishes, and of sheep, oxen, pigs, dogs, elephants, and men contain different and special chemical substances, corresponding to the "cetyl" which is present in the fat of the sperm whale's head.
It is a combination of palmitic acid and a peculiar hydrocarbon, called (after the whale) "cetyl," and easily forms pure crystals.
For instance, cetyl and cetearyl alcohol are waxy, solid emollients that act as thickeners and emulsifiers in a product, and they moisturize the skin as a by-product.
Palmitates ethylhexyl, isopropyl, and cetyl palmitates are also emollients
Cornstarch acts as a thickener and binder in cooking, just as an emulsifier such as stearic acid or cetyl alcohol in a cosmetic makes the texture smoother and holds oil and water together.
Cetearyl, cetyl, and stearyl alcohol also a waxy emollient that adds opacity to color
When choosing a toner, avoid potentially drying or disruptive ingredients, like fragrance, propylene glycol, sulfates, and alcohols other than ceteryl or cetyl.

As examples may be cited beeswax, containing myricin or myricyl palmitate, and spermaceti, consisting chiefly of cetin or cetyl palmitate, and herein lies the essential difference between fats and waxes, but as these substances are not soap-making materials, though sometimes admixed with soap to accomplish some special object, they do not require further consideration.
