2-Ethylhexyl 4-dimethylaminobenzoate

Perfumes, Flavors, Cosmetics, and Soap. Many naturally occurring esters in essential oils and some synthetic esters are important fragrance and flavor compounds (61,62). They are used in perfumes, flavors, cosmetics, soaps, deteigents, and air fresheners. Benzyl, butyl, ethyl, methyl, and phenyl esters of benzoic acid are used as flavors, perfumes, and food preservatives. Glyceryl 4-aminobenzoate [13644-7] and 2-ethylhexyl 4-dimethylaminobenzoate [21245-02-3] are used in cosmetic sunscreen preparations. Alkyl esters of 4-hydroxybenzoic acid, called parabens, have been used under various names for fungus infections of the skin, and as preservatives in lotions and creams (101). Soap and cosmetic fragrances use large amounts of amyl and benzyl salicylate. Benzyl salicylate [118-58-1] is also used in deodorant sprays. 2-Ethylhexyl salicylate [118-60-5] and 2-ethylhexyl 4-methoxycinnamate [5466-77-3] are used in sunscreen formulations (102).

Figure 11.12. Effect of fraction of stoichiometric concentration of 2-ethylhexyl-p-dimethylaminobenzoate used for ionic plasticization of poly(styrene-b-isobuty-lene-b-styrene), having 4.7% sulfonated phenyl units, on glass transition temperature, Tg, and temperature at which tan6=3.

Plasticization of poly(styrene-b-isobutylene-b-styrene) ionomer by 2-ethylhexyl-p-dimethylaminobenzoate causes a decrease in the glass transition temperature, Tg, as the amount of plasticizer increases (Figure 11.12). This lowering of the Tg indicates that there is a slight plasticization of the non-ionic polystyrene phase. A much larger shift is observed in temperature at which tan5 = 3. This indicates a prefererrtial plasticization of the ionic clusters.
