摘要:
A novel monophosphate and a novel diphosphate prepared by a phosphatidyl transfer reaction of a phospholipid and an alcohol in the presence of phospholipase D are disclosed. The phosphates can independently or together form small and stable liposomes which can include active components therein. Cosmetic compositions comprising these phosphates or liposomes penetrate well into the hair and the skin, and exhibit long-lasting excellent moisture-retaining, beauty, skin-activation effects.
摘要:
Metal salts of monoalkyl phosphates of the following formula ##STR1## in which each R represents a saturated or unsaturated, linear or branched hydrocarbon group having from 8 to 32 carbon atoms, and M represents an alkaline earth metal or divalent transition metal.The metal salts are particularly suitable as cosmetic powders, fillers for resins, and lubricants, parting agents and pigment dispersants for polymeric compounds. When used as cosmetic powders, the metal salts improve spreadability, moistness, smoothness, adherence, transparency and covering power of cosmetics.Preparation process of the metal salts is also disclosed.
摘要:
An alkali metal monoalkylphosphate having a saturated or unsaturated straight-chain or branched hydrocarbon group having from 8 to 32 carbon atoms is described; also described is a process for preparing particles of said alkali metal zinc monoalkylphosphate and cosmetics containing said particles.

摘要:
Phosphoric acid esters represented by the following formulae (I) and (IX) as well as processes for preparing them are disclosed. ##STR1## wherein R.sub.1 represents a linear or branched, alkyl or alkenyl group having a C.sub.1-36 carbon atom content, with or without the hydrogen atom(s) being substituted with fluorine atom(s), or a phenyl group with substituted linear or branched alkyl group(s) having a C.sub.1-15 carbon atom content, R.sub.2 represents an alkylene group having a C.sub.2-3 carbon atom content, R.sub.3 and R.sub.4 independently denote a hydrogen atom or an alkyl group having a C.sub.1-3 carbon atom content, R.sub.5 and R.sub.6 independently denote a hydrogen atom, or an alkyl, alkenyl, or phenyl group with or without the hydrogen atom(s) being substituted with group(s) containing hetero atom(s), excepting for a mercapto group, R.sub.7 and R.sub.8 independently denote a hydrogen atom, or an alkyl, or alkenyl group, m is an integer of 0-30, n is an integer of 0-5, l is an integer of 0-3, M is a hydrogen atom, an alkali metal, an alkali earth metal, an ammonium group, an alkyl amine group, or an alkanol amine group. The phosphoric acid esters have outstanding surface activity and good foaming capability, and imparts only extremely low irritation to the skin. The detergent composition into which they are formulated is particularly useful as, shampoo, baby shampoo, body shampoo.

A peptide or protein is modified by reacting a phosphoric acid ester represented by the following general formula (I) with a peptide or protein: ##STR1## wherein R.sub.1 means a linear or branched, C.sub.1-36 alkyl or C.sub.2-36 alkenyl group whose hydrogen atom or atoms may be substituted by the corresponding number of fluorine atom(s) or a phenyl group substituted by at least one linear or branched C.sub.1-15 alkyl group, R.sub.2 denotes a C.sub.2-3 alkylene group, m stands for a number of 0-30, and M is a hydrogen atom, an alkali metal ion, an alkaline earth metal ion, an ammonium ion, an alkylamine residue or an alkanolamine residue.
摘要:
A novel method for purifying a sugar phosphate or its salt, in which a sugar-containing mixture of a sugar phosphate or its salt and phosphoric acid or its salt is subjected to electrodialysis to remove the phosphoric acid or its salt from the mixture.According to this method, the phosphoric acid or its salt can be readily obtained in a reusable form. The method is thus quite advantageous in view of the economy.
