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. .

CODEN: FRXXBL. CLASS: IC: C10M003-20. APPLICATION: FR 74-29459 22 Aug 1974. DOCUMENT TYPE: Patent CA Section: 76 (Electric Phenomena) Conventional wound capacitor was fabricated, and impregnated with the liq. mixt. 2-ethylhexyl 2-ethylhexanoate (I) 75 + p-phenoxybenzonitrile 25% that has, due to I, a significantly greater thermal and chem.Several reagents with their cas registry numbers 3096-81-9 and 7425-14-1 are used here. stability of its dielec.-loss characteristics on aging (e.g., in air at 110.degree. for .ltoreq.1500 h) than other known dielec. liqs. (e.g., dioctyl phthalate). A convential high-voltage transformer was also fabricated, and impregnated with pure I. Other stabilized dielec. liqs. can also be prepd. by mixing .gtoreq.10% of I with other known liq. dielecs. .
