A dextrin fatty acid ester is provided in which the dextrin has an average degree of glycopolymerization of 3 or more and 100 or less. The fatty acid comprises one or more linear saturated fatty acids having 14 or more and 18 or less carbon atoms, and one or more branched saturated fatty acids having 14 or more and 18 or less carbon atoms. The molar fraction of the linear saturated fatty acid in the fatty acid is 0.75 or more and 0.95 or less. The average degree of substitution of the fatty acid per glucose unit is 1.5 or more and 2.0 or less.

Dextrin fatty acid ester and cosmetic

An object of the present invention is to provide novel dextrin fatty acid ester that is excellent in tackiness and useful as a base for cosmetics and the like. The novel dextrin fatty acid ester is prepared by esterification between dextrin and fatty acids, wherein the dextrin has an average degree of glucose polymerization of 3 to 150; the fatty acids comprise more than 50 mol % and 100 mol % or less, based on the total amount of the fatty acids, of one or more saturated branched fatty acids having 4 to 26 carbon atoms, and 0 mol % or more and less than 50 mol %, based on the total amount of the fatty acids, of one or more fatty acids selected from the group consisting of saturated linear fatty acids having 2 to 22 carbon atoms, unsaturated linear or branched fatty acids having 6 to 30 carbon atoms, and saturated or unsaturated cyclic fatty acids having 6 to 30 carbon atoms; and the degree of substitution by the fatty acids is 1.0 to 3.0 per glucose unit.

Dextrin fatty acid ester that does not cause gelation of liquid oil, and uses thereof

A modified organopolysiloxane in which a carboxyl group of a heterocyclic compound having a carboxyl group and containing a nitrogen atom as a heteroatom is combined with an amino group of an amino-modified silicone is used as a gelling agent for low-viscosity silicone oil, which can allow the low-viscosity silicone oil to stably gel without losing the characteristics thereof.

Modified organopolysiloxanes, production thereof and compositions

Disclosed are amino silicone derivatives having triazinyl groups or pyrimidinyl groups bound to amino groups of amino silicones, their production and use, said silicone derivatives being able to gel silicone oil or to increase the viscosity thereof stably and homogeneously, and therefore being useful as bases for cosmetics, pharmaceutical preparations and industrial materials.

Silicone derivatives, their production and use

Disclosed are a dextrin ester of fatty acids in which dextrin has an average saccharide polymerization degree of 3 to 150, the fatty acids comprise a straight chain fatty acid having 8 to 22 carbon atoms and at least one fatty acid selected from the group consisting of branched fatty acids having 4 to 26 carbon atoms, unsaturated fatty acids having 6 to 30 carbon atoms and straight chain saturated fatty acids having 6 or less carbon atoms, and the substitution degree of fatty acids per glucose unit is 1.0 to 3.0; and a gelling agent, a composition and a base comprising the ester, the ester being excellent in thixotropic property, moisture retaining property, emulsifiability, adhesion and dispersibility, and therefore suitably used for cosmetics, printing ink, coatings, etc.

Dextrin ester of fatty acids and use thereof

An oligosaccharide lipid is provided which has 2 to 20 saccharide units, and has a hydrophobic group linked by an ether linkage to an anomer carbon on a reducing end group. A stabilizer for a phospholipid vesicle is also provided which comprises an oligosaccharide derivative having 2 to 20 saccharide units, and having a hydrophobic group linked by an amide linkage or an ether linkage to an anomer carbon on a reducing end group constituted of an aldose.

Stabilizer for phospholipid vesicles
