| 摘要 |
<p>A pigment (or body) composed of particles having surfaces covered with a high molecular substance containing a group of the formula -COOR, where R stands for a hydrogen or metal atom, and having an acid value of at least 200 when the R in the formula stands for a hydrogen atom. It has a high power of absorbing and holding moisture. The surfaces of the pigment particles are alternatively covered with both such a high molecular substance and a substance which makes the surfaces hydrophobic. This pigment has a good affinity for oil and yet a high power of absorbing and holding moisture. A cosmetic containing any such pigment has a high moisturizing power and provides a long makeup life.</p> |
