Thus, it is important to develop new non-cationic conditioning agents and formulations that offer similar aesthetic properties to silicones. Likewise, there is a need for a conditioning shampoo that can clean, condition and increase manageability; for example, exhibit improved curl retention and frizz control. Tests of formulas incorporating these compositions show they act as efficient conditioning materials and have equal or better performance, compared with leading conditioning ingredients.

Black, bright pigment in cosmetic, coating, resin and ink compositions
European Patent EP1666541
Publication date: Dec. 21, 2011
Assignee: Nippon Sheet, Glass Co., Ltd.

This patent relates to a flaky, black, bright pigment to be added to a cosmetic, coating material, coating film, etc. With respect to metallic pigments comprising glass flakes coated with a nickel alloy with a thickness of 0.04 µm or less and showing black appearance, there is a problem in that the hiding power is low and the coloration is weak. If the thickness of the coating is thick, the metallic gloss becomes intense and the color that appears becomes glossy white gray to gray, which does not produce a glossy black color tone. However, this pigment provides for a flaky, black, bright pigment having a high hiding power that is excellent in skin feel, smoothness and spread when applied in cosmetics.
