Branched-chain esters of isooctanoic acid for cosmetics

Branched-chain esters of isooctanoic acid for cosmetics.Some chemicals with cas registry numbers like 41669-30-1 and 90453-99-9 are also used. Brunke, Ernst Joachim; Rojahn, Willi (Dragoco Gerberding und Co. G.m.b.H., Fed. Rep. Ger.). Ger. Offen. DE 3231706 A1 1 Mar 1984, 14 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: A61K007-40; A61K007-02; A61K007-48. APPLICATION: DE 82-3231706 26 Aug 1982. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 23, 63 Branched-chain (1-3 Me or Et groups) C8-18 alkyl esters of tech. isooctanoic acid (mixt. of C8 acids with 1 or 2 Me branches) are prepd. for use in cosmetics to improve moisture permeability when applied to the skin and to improve spreadability on the skin. The variations in isooctanoic acid isomer compn. in the com. product had no noticeable effect on the cosmetic properties of a given ester. Thus, isooctanoic acid was esterified with MeOH, 2-ethylhexanol [104-76-7], 3,5,5-trimethylhexanol [3452-97-9] isodecanol [25339-17-7], isotridecanol [27458-92-0] or isooctadecanol [27458-93-1] in toluene soln. contg. H2SO4, and the product was neutralized, washed, and distd. The isomer compn. of Me isooctanoate [68517-10-2] and 2-ethylhexyl isooctanoate [81897-25-8] was detd. by gas chromatog., and the mass spectra of the major isomers of the latter are given. The horizontal spreadability on filter paper of the esters exceeded that of paraffin oil and that of a com. straight-chain aliph. 2-ethylhexanoate, and decreased in the order: 2-ethylhexyl ester, isodecyl isooctanoate [89933-26-6], isotridecyl isooctanoate [89933-27-7], 3,5,5-trimethylhexyl isooctanoate [89933-28-8], and isooctadecyl isooctanoate [41669-30-1]. Formulations are given for a sunscreen, face cream, and ointment base contg. the esters. .

Branch-chained esters of 2-ethylhexanoic acid for cosmetics

Branch-chained esters of 2-ethylhexanoic acid for cosmetics. Brunke, Ernst Joachim (Dragoco Gerberding und Co. G.m.b.H., Fed. Rep. Ger.). Ger. Offen. DE 3231705 A1 1 Mar 1984, 10 pp. (German). (Germany).Several reagents with their cas registry numbers 89933-25-5 and 25339-17-7 are used here. CODEN: GWXXBX. CLASS: IC: A61K007-40; A61K007-02; A61K007-48. APPLICATION: DE 82-3231705 26 Aug 1982. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 23, 63 Branched-chain (1-3 Me or Et groups) C8-18 alkyl esters of 2-ethylhexanoic acid are prepd. for use in cosmetics to improve water vapor permeability on the skin, eliminate rancidification problems, and to improve spreadability. Thus, 2-ethylhexanoic acid was esterified with 3,5,5-trimethylhexanol [3452-97-9], isodecyl alc. [25339-17-7], isotridecyl alc. [27458-92-0], or isostearyl alc. [27458-93-1] in toluene soln. contg. H2SO4, and the ester was neutralized, washed and distd. The spreadability in 20 min when applied to filter paper was: 2-ethylhexyl 2-ethylhexanoate [7425-14-1] 36.7, 3,5,5-trimethylhexyl 2-ethylhexanoate [85118-40-7] 34.8, isodecyl 2-ethylhexanoate [34962-91-9] 27.3, isotridecyl 2-ethylhexanoate [89933-25-5] 24.2, and isostearyl 2-ethylhexanoate [69247-83-2] 19.9 cm2 vs. 19.9 cm2 for paraffin oil. Formulations for a sunscreen, face cream, and ointment base contg. the esters are given. .
