AI Technical Summary
【0011】 本発明によれば、水系媒体(分散媒)中で分散質を安定的に分散させ、分散状態を安定化することが可能となる。そのため、化粧料全体の粘度を上げることなく、顔料が良好に分散し、顔料の過度な沈降が防止された水性化粧料を得ることができる。また、顔料と併用するスイゼンジノリ由来硫酸化多糖類は藻類由来成分であることから、石油原料からの合成成分と比して安心安全に使用することができる上、スイゼンジノリ由来硫酸化多糖類自体にも保湿効果、肌バリア効果、抗炎症効果等が期待されることから、分散剤、沈降防止剤としてのみならず各種の肌機能や肌状態を向上·改善することができる。

Abstract
Claims
1. A dispersant for aqueous cosmetic compositions containing sulfated polysaccharides derived from Suizenji-nori as an active ingredient, The aforementioned dispersant for aqueous cosmetic compositions is used in aqueous cosmetic compositions containing a coloring pigment or pearl pigment and an aqueous medium. In the aqueous cosmetic composition, the content of the dispersant for aqueous cosmetic composition is 0.03% by mass or more and 0.083% by mass or less. In the aqueous cosmetic composition, the mass ratio of the dispersant for the aqueous cosmetic composition to the coloring pigment or the pearl pigment is 1:1 to 5:
1. A dispersant for aqueous cosmetic compositions, characterized in that the coloring pigment or pearl pigment is not treated to make its surface hydrophilic.
2. An aqueous cosmetic composition comprising the dispersant for aqueous cosmetic compositions according to claim 1, a coloring pigment or pearl pigment, and an aqueous medium, In the aqueous cosmetic composition, the content of the dispersant for the aqueous cosmetic composition is 0.03% by mass or more and 0.083% by mass or less. In the aqueous cosmetic composition, the mass ratio of the dispersant for the aqueous cosmetic composition to the coloring pigment or the pearl pigment is 1:1 to 5:
1. An aqueous cosmetic composition characterized in that the coloring pigment or pearl pigment is not surface-treated to make it hydrophilic.
3. A dispersion method for stabilizing the dispersion state in an aqueous cosmetic composition containing a dispersed phase and an aqueous medium as a dispersion agent, The aqueous cosmetic composition contains a sulfated polysaccharide derived from Suizenji-nori as a dispersant. The dispersed phase is a coloring pigment or a pearl pigment. The content of the dispersant in the aqueous cosmetic composition is 0.03% by mass or more and 0.083% by mass or less. In the aqueous cosmetic composition, the mass ratio of the dispersant to the coloring pigment or pearl pigment is 1:1 to 5:
1. A dispersion method characterized in that the coloring pigment or the pearl pigment is not subjected to a surface hydrophilic treatment.
