The present invention provides a substantially spherical composition comprising about 60 to 80 percent by weight pearlescent pigment, 14 to about 38 percent by weight wax, and about 2 percent to 6 percent surfactant. This composition is particularly useful for extrusion into any polymer used for masterbatching. The masterbatch is then typically blow or injection molded or extruded into a finished part.

L'invention concerne une composition sensiblement sphérique qui comprend entre 60 et 80 % en poids d'un pigment perlé ; entre 14 et environ 38 % en poids de cire ; et entre environ 2 et 6 % en poids de tensioactif. Cette composition s'avère particulièrement utile pour l'extrusion de tout polymère utilisé pour la préparation de mélange maître. Le mélange maître est ensuite généralement moulé par soufflage ou par injection ou extrudé en pièce finie.
