FINE PARTICLE DISPERSANT, AND COSMETICS, COATING MATERIALS, INKS, STORAGE MATERIALS AND LUBRICANTS, CONTAINING THE SAME |
摘要 |
<p>The present invention discloses a fine particle dispersant containing at least one member selected from the group consisting of ester compounds of the following general formulae (I) and/or (II) obtained from erythritol and/or its condensate and a fatty acid(s), polycondensates of erythritol and/or its condensate and a polyvalent carboxylic acid(s), polycondensates of erythritol and/or its condensate, the ester compounds and a polyvalent carboxylic acid(s), polycondensates of an ester compound of erythritol and/or its condensate and the polyvalent carboxylic acid(s) and the fatty acid(s), and polycondensates of erythritol and/or its condensate and the fatty acid(s) and/or the polyvalent carboxylic acid(s). <CHEM> wherein R1 to R4 each independently represent a hydrogen atom, a fatty acid residue or a polyvalent carboxylic acid residue, R5 and R6 each independently represent a hydrogen atom, a fatty acid residue or a polyvalent carboxylic acid residue. This fine particle dispersant is excellent in fine particle dispersibility and the properties (smell and color) thereof are scarcely deteriorated in heat stability tests.</p> |
