Esters are common components in cosmetics and skin-care products. They can be synthesized from fatty acids and alcohols using either chemical or enzymatic reactions. The chemical reactions are normally catalysed by acid catalysts. Enzymatic synthesis is carried out under milder conditions and therefore it provides products of very high purity. A range of esters such as isopropyl palmitate and isopropyl myristate are now produced industrially using enzymatic synthesis. The reactions are carried out in solvent-free systems using an immobilised lipase as catalyst. In order to get high yields in the reactions, water is removed continuously. 

The fatty acid methyl esters C16.0, C18.0, and C18.2 indicate the presence of a vegetable oil. However, the detection of isopropyl palmitate (IPP) and isopropyl stearate (IPS) in the Py-GC experiment (not shown) means that there would also be a contribution of their fatty acids to this pyrogram. The methyl ethers of cetyl alcohol (C16-OME) and stearyl alcohol (C18-OME) suggest the presence of the respective free fatty alcohols, and this is confirmed by an inspection of the pyrogram from the Py-GC experiment (not shown). Myristyl alcohol methyl ether (C14-OME) and myris-tic acid methyl ester (CM. 0) originate from myristyl myristate used in the formulation.

Several other solvents are used extensively in topical formulations. Isopropyl myristate (1PM) could be classified as an oily ingredient, which can be grouped within a series of isopropyl fatty acid esters such as isopropyl linoleate and isopropyl palmitate. 1PM has been included in emulsions and gels at around 10%...

Linko et al. 1998). Lipases have been extensively used in the production of surfactants of different chemical nature by esterification of alkyl glycosides and fatty acids, by transesterification of natural oils and alcohols, by transesterification of phospholipids and alcohols, and also by esterification of amino acids and amides (Saxena et al. 1999). Personal care products, hke isopropyl myristate and isopropyl palmitate, have been produced in solvent-free media with immobilized lipase and wax esters (esters from long-chain fatty acids and fatty alcohols) are also being produced with lipases (Hasan et al. 2006).

More recently Webb et al. (1952) reported no isopropyl alcohol in a wine fusel oil sample. They did find 4.1% n-propyl, 1.9% n-butyl, 4.9% ( — )-sec-butyl, 18.3% isobutyl, 9.6% ( —)-2-methyl-l-butanol, 54% isoamyl, trace of n-amyl, 1.5% n-hexyl, 5.6% esters, and traces of acetic and butyric acids and acetal. The esters included 0.19% ethyl caproate, 0.60% ethyl caprylate, 0.52% isoamyl caprylate, 1.32% ethyl caprate, 0.38% isobutyl caprate, 0.58% ethyl laurate, 0.25% ethyl palmitate, a trace of butyrate ester, 0.06% myristate ester. Probably present were methyl salicylate, isoamyl caprate, active amyl caproate, isoamyl caproate, active amyl caprylate, isobutyl caprylate, active amyl caprate, active amyl laurate, and isoamyl laurate. 

Waxes are esters of higher fatty acids and fatty alcohols. Pharmaceutically important examples are the liquid Decyl oleate (unsaturated Cetiol V ), the semisolid Wool fat (Adeps lanae) and the solids Yellow wax (Cera flava). Bees wax, white (Cera alba, white wax) and Cetyl palmitate (Cetaceum). The solid waxes are mainly used to increase the consistency of semisolid skin preparations (see Sect. 12.5.2). Waxy liquid compounds are ethyl oleate, isopropyl myristate and benzyl benzoate. In the first two cases the fatty acid is esterified with a short-chain alcohol.
