摘要:
The present invention provides a method for producing a purified lipase which comprises steps of: (a) bringing a long chain fatty acid triglyceride and a medium-chain triglyceride into contact with a lipase to purify the lipase; and (b) collecting the purified lipase. According to this production method, the purified lipase can be obtained wherein content of impurity such as silicon is decreased.
摘要:
A method for producing a lipase powder, which comprises the step of spray drying an aqueous solution containing a lipase adjusted to pH 6 to 7.5; the lipase powder which is a 1,3-specific lipase derived from Rhizomucor miehei, spherical, and contains not more than 10% by weight of moisture; and a lipase composition wherein the lipase powder is immersed or impregnated in fatty oil. According to the present invention, a lipase powder of which 1,3-selectivity is improved can be provided.

摘要:
There is provided a lipase composition comprising (a) a powdered lipase which is a lipase derived from Rhizomucor sp. or a powdered lipase which is a lipase derived from Penicillum sp. and (b) a powdered lipase selected from the group consisting of a powdered lipase which is a lipase derived from Alcaligenes sp., a powdered lipase which is a lipase derived from Rhizopus sp. and a powdered lipase which is a lipase derived from Thermomyces sp. When using this lipase composition, a compound(s) having at least one alcoholic hydroxyl group in the molecule can be effectively esterified with a carboxylic acid(s).

摘要:
A branched monoester represented by the formula R.sup.1 COOR.sup.2 acts as a silicone-dissolving or solubilizing agent. In the formula, R.sup.1 is an isoalkyl group having 4 to 17 carbon atoms, and R.sup.2 is an isoalkyl group having 3 to 18 carbon atoms.
摘要:
Diclosed is a lanolin-like synthetic oil produced by esterification of glycerol with a branched fatty acid having 6 to 14 carbon atoms, a linear fatty acid having 15 to 28 carbon atoms and a dibasic acid having 4 to 10 carbon atoms while all the following conditions (a) to (c) are satisfied:(a) molar ratio of the branched fatty acid to the linear fatty acid ranges from 1.7 to 2.3,(b) 0.7 to 0.8 mol of the dibasic acid is used per mol of glycerol, and(c) the number of remaining hydroxyl group ranges from 0.4 to 0.6 for three hydroxyl groups of glycerol.The synthetic ester oil has a color, smell and stability superior to those of lanolin and an adherability, spreadability, gloss and touch very similar to those of lanolin. Such an oil can be suitably incorporated into cosmetics, toiletries and external preparations to overcome the defects of lanolin and also to exhibit the characteristic features of the oil.
