    Abstract: An alkyd type novel branched polycondensate is provided to be formulated into a nail vanish composition which is able to maintain improved covering property and gloss. A cosmetic or pharmaceutical composition comprises at least one polycondensate in a cosmetically or a pharmaceutically acceptable medium, wherein the polycondensate is obtained by reacting 15-30 wt.% of at least one polyol having 3-6 hydroxyl groups; 5-40 wt.% of at least one C6-20 saturated or unsaturated, linear, branched and/or cyclic non-aromatic monocarboxylic acid; 10-55 wt.% of at least one C7-11 aromatic monocarboxylic acid(which may be substituted with one to three C1-32 saturated or unsaturated, linear, branched and/or cyclic alkyl radical(s)); and 10-25 wt.% of at least one saturated or unsaturated, or aromatic, linear, branched and/or cyclic polycarboxylic acid having 2-4 COOH(s) or a cyclic anhydride thereof. A method for preparing the polycondensate comprises the steps of: (a) mixing a polyol with aromatic and non-aromatic monocarboxylic acid; (b) heating the mixture under inert atmosphere to a melting point and then heating it to a temperature of 150-220 deg.C to completely consume the mono-carboxylic acid; (c) cooling the mixture down to 90-150 deg.C; (d) adding polycarboxylic acid and/or cyclic anhydride thereof, and optionally silicone having hydroxyl or carboxyl to the mixture; and (e) heating it to a temperature of 220 deg.C or less.

    Abstract translation: 提供醇酸型新型支链缩聚物以配制成能够保持改善的覆盖性和光泽的指甲消失剂组合物。 化妆品或药物组合物在化妆品或药学上可接受的介质中包含至少一种缩聚物，其中所述缩聚物通过使15-30重量％的至少一种具有3-6个羟基的多元醇反应而获得; 5-40重量％的至少一种C6-20饱和或不饱和的直链，支链和/或环状的非芳族一元羧酸; 10-55重量％的至少一种C 7-11芳族单羧酸（其可以被一至三个C1-32饱和或不饱和的直链，支链和/或环状烷基取代）; 和10-25重量％的至少一种具有2-4个COOH或其环状酸酐的饱和或不饱和或芳族，直链，支链和/或环状多元羧酸。 制备缩聚物的方法包括以下步骤：（a）将多元醇与芳族和非芳族一元羧酸混合; （b）将混合物在惰性气氛下加热至熔点，然后将其加热至150-220℃，以完全消耗单羧酸; （c）将混合物冷却至90-150℃; （d）向混合物中加入聚羧酸和/或其环状酸酐，和任选具有羟基或羧基的硅氧烷; 和（e）将其加热至220℃或更低的温度。
