Attention cosmetic chemists We think hexadecyl alcohol offers a combination of properties that make it a natural for use in creams, lotions, bath oils, shampoos and more. In fact, we have six good reasons why hexadecyl alcohol deserves a try in your cosmetic and toiletry formulations. Here they are: it is an excellent emollient without a "greasy" feel; it is non-toxic systemi- cally when applied to the skin; it is non- irritating topically at use levels; it is sta ble; it is colorless, and it is a relatively inexpensive compound. Any takers? The fatty acid esters of hexadecyl alcohol look promising for topical prep- arations, too. The laurate, myristate, stéarate, and oleate are all stable, light- colored liquids and excellent emollients. Enjay doesn't make the esters but we can steer you to someone who does. Or you can make them yourself; there's no great hick to it. And surfactant specialists If you use surfactants or if you make them, here's something of interest to you. Hexadecyl alcohol is a starting material for fast-acting wetting agents that are already being used in textile wet processing, and other derivatives look very "promising indeed. Take so- dium hexadecyl sulfate, for example. This compound is a remarkably fast wetting agent when evaluated in a modified Draves test. It gives sinking times of 3.5 seconds compared to 3.0 seconds for the same concentration of di-(2-ethylhexyl) sulfosuccinate, which is probably the fastest anionic wetting agent in general use today. And sodium hexadecyl sulfate will not hydrolyze in alkaline solutions such as are used in kier boiling cotton. It's quite stable in dilute acid solutions, too. What's more, sodium hexadecyl sulfate has some solu- bility in kerosene, Varsol®, linseed oil, and aromatic solvents. So if you are looking to add wetting power to non- aqueous media, you know what to try. Hexadecyl alcohol will add ethylene oxide to give a series of adducts with outstanding wetting, foaming and de- tergency properties, especially in the 10-15 mole range. The properties of these non-ionic surfactants may be varied depending on the extent of the reaction, which goes smoothly and in good yield. Sulfation of the ethylene oxide ad- ducts of hexadecyl alcohol gives another series of surface active compounds which are extremely effective emulsify- ing agents. The sulfate of the four-mole ethylene oxide adduct is a superior foaming agent. Enjay does not produce any of the surface active compounds derived from hexadecyl alcohol. But we can tell you where to get some of them, and how to make the others; just write us. A little blue-sky stuff We have a few choice fields of applica- tion (some a little speculative) left for hexadecyl alcohol. For instance, a thin film of hexadecyl alcohol (it spreads it- self), will retard the rapid evaporation of water. Put it on or near vegetation and it should help cut down water loss; at high levels it even seems to have a gen- eral growth retarding action on plants. Hexadecyl alcohol looks good in for- mulations for textile lubricants, lubri- cants for machine picking of cotton, and in lubricant formulations for cold rolling of non-ferrous metals, especially alu- minum. The long chain fatty acid esters are promising synthetic lubricants; the alcohol helps improve printing inks. You might try hexadecyl alcohol as a leather softener, (it is an excellent emollient), or as a mold release agent since it has good lubricating properties.
