High chroma glitter pigments combine large particle interference pigments and absorption colorants to bring about a unique look. Unlike traditional glitter pigments, the high chroma glitter pigment does not exploit metallic coatings to achieve the sparkle effect. These high chroma glitter pigments produce optical effects and coloration without the need for incorporating additional pigments which, in turn, is a benefit from both a formulation and cost standpoint. In addition to a sparkle effect, the present invention provides high chroma over both dark and light backgrounds, which has been thus far unrealized in prior art. Materials used in the present invention are ethically sourced, environmentally friendly, free of plastic, free of heavy metals, and regulated for cosmetic applications.
A high chroma glitter pigment comprising an ultra large flaky substrate, one or more absorption pigments or dyes, and an optional adhesion layer.
