PVD-aluminum pigment dispersion and cosmetic formulations

A method of producing an effect pigment dispersion, the method comprising:

• providing a leafing PVD-aluminum dispersion in an organic solvent, the dispersion comprising a PVD-aluminum pigment and a leafing additive,
• adding an oil suitable for cosmetic skin or color cosmetic applications to the PVD-aluminum dispersion, and
• removing the organic solvent,
• wherein the amount of the PVD-aluminum pigment is in a range of 8 to 30 wt.-%, the amount of the oil is in a range of 70 to 90 wt.-%, each based on the total weight of the dispersion, and
• the leafing additive is partly adsorbed on the surface of the PVD-aluminum pigment and partly present in an excess amount dissolved in the oil, wherein the excess amount is in a range of 0 to 25 wt.-%, based on the weight of PVD aluminum pigment.

A method of producing a cosmetic skin or color cosmetic formulation, the method comprising:

• preparing a phase A by mixing formulation ingredients,
• providing a phase B comprising an effect pigment dispersion, the effect pigment dispersion comprising a PVD-aluminum pigment, a leafing additive and an oil suitable for cosmetic skin care or color cosmetic applications, wherein the amount of the PVD-aluminum pigment is in a range of 8 to 30 wt.-%, the amount of the oil is in a range of 70 to 90 wt.-%, each based on the total weight of the effect pigment dispersion, and the leafing additive is partly adsorbed on the surface of the PVD-aluminum pigment and partly present in an excess amount dissolved in the oil, wherein the excess amount is in a range of 0 to 25 wt.-%, based on the weight of PVD aluminum pigment,
• mixing and homogenizing phase A and phase B to prepare a cosmetic formulation, and
• pouring or filling the cosmetic formulation into a container or packaging.
