Embodiment 1

[0055] To the reaction flask was filled with 78.4g of polyglycerol with an average polymerization degree of 20 and 295.9g of behelpric acid (C22), 25.7g12-hydroxystearic acid (hydroxyC18), 0.8g of potassium hydroxide was added, and then the esterification reaction was carried out at 250 ° C, thereby obtaining a thickening or curing agent composed of polyglyceride fatty acid with a esterification rate of 84%. (In terms of constituent fatty acids, the doping ratio (mass ratio) of (1) is a straight-chain saturated fatty acid with a carbon atomic number of 16 to 24, and (2) is a hydroxy fatty acid and hydroxy fatty acid polypolymer, (1) :(2) is 92:8.) )

Embodiment 2～15、 comparative example 1～7

[0057]The same operation as Example 1, to the mixing ratio (mass ratio) described in Table 1, 2 to the reaction flask into the reaction flask of the average polymerization of polyglycerol and fatty acids (1) ~ (3) recorded in Table 1, 2, adding 0.8g potassium hydroxide, and then esterification reaction at 250 ° C, thereby obtaining a thickening or curing agent composed of polyglycerol fatty acid esters. The esterification rate is shown in Tables 1 and 2. It should be noted that the "hydroxyL C18 2.5 polymer" used in Example 8 is modulated by loading 300.0g 12-hydroxystearic acid into a reaction flask, adding 0.8g of potassium hydroxide, and then dehydration condensation reaction at 250 ° C until the acid value is 77.6. Further, the "hydroxyL C186 polymer" used in Example 9 is modulated by filling the reaction flask with 300.0g 12-hydroxystearic acid, adding 0.8g of potassium hydroxide, and then dehydration condensation reaction at 250 ° C until the acid value is 32.8.

Abstract

The present invention provides a thickening or curing agent which is a thickening or curing agent for an oil agent and contains a polyglycerol fatty acid ester that satisfies the following conditions (A) to (E). (A) The polyglycerol has an average degree of polymerization of 10 or more. (B) at least one straight-chain saturated fatty acid having 16-24 carbon atoms; (C) contains one or more substances selected from the group consisting of hydroxy fatty acids and hydroxy fatty acid polycondensates; (D) the esterification rate is 70% or more; (E) The mass ratio of component (B): component (C) is from 80: 20 to 98: 2. The thickening or curing agent according to the present invention can be used as a raw material for cosmetics, pharmaceuticals, foods and drinks, industry, and the like.

Description

Technical field [0001] The present invention relates to: a thickening or curing agent comprising an oil agent comprising a particular polyglyceride fatty acid ester, an oil company comprising the thickening or curing agent, and cosmetics containing the oil agent. Background [0002] In the field of cosmetics, as a technique for thickening liquid oils, there is a known method of adding 12-hydroxystearic acid, dextrin fatty acid ester. However, they are almost always high melting points, above 75 ° C, and are difficult to dissolve in oil agents. In addition, in order to use these ingredients to thicken the cosmetic oil, it is necessary to mix a lot, and it will become sticky after application and rinse, etc., which cannot meet the sense of use. [0003] As other techniques, there is known to be a method of adding polyglyceride fatty acid esters, which have a low melting point and are easily soluble in oil agents. In addition, there is no need to mix a lot of cosmetic oils for thick...
