Cosmetic compositions with encapsulated pigments and a method for using
View Patent ↗There is a pigmented cosmetic composition. The composition has a cosmetically acceptable vehicle, a cosmetic active, and a plurality of encapsulated pigment particles. The particles have an encapsulant and an entrapped pigment within the encapsulant. The encapsulant has silicon dioxide and exhibits a refractive index of about 1.4 to about 1.6.
1. A method of imparting a cosmetic effect of a natural-looking cosmetic effect to skin or lips, comprising topically applying to the skin or lips a cosmetic composition comprising:
a cosmetically acceptable vehicle and a plurality of spherical iron oxide pigment particles encapsulated by a layer of silicon dioxide enclosing the iron oxide pigment particle, wherein the silicon dioxide encapsulant is about 3 wt % to about 12 wt % by weight of the encapsulated iron oxide pigment particles.
2. The method of claim 1 , wherein the encapsulated spherical iron oxide pigment particles are present from about 1 wt % to about 15 wt % by weight of the composition.
3. The method of claim 1 , wherein the spherical iron oxide pigment particles are present in an amount of from about 1 wt % to about 15 wt % by weight of the composition.
4. The method of claim 1 , wherein the composition is applied to lips.
5. The method of claim 1 , wherein the composition is applied to the skin.
6. The method of claim 1 , wherein the composition is non-pearlescent.
7. The method of claim 1 , further comprising an active ingredient.
8. The method of claim 7 , wherein the active agent is selected from the group consisting of anesthetics, anti-allergenics, anti-inflammatories, botanical agents, de-pigmenting agents, de-wrinkling agents, emollients, exfoliants, fragrances, humectants, lubricants, moisturizers, skin penetration enhancers, sunscreen agents, surfactants, vitamins, and combinations thereof.
9. A method of imparting a cosmetic effect of a natural-looking cosmetic effect to skin or lips, comprising topically applying to the skin or lips a cosmetic composition comprising:
a cosmetically acceptable vehicle and a plurality of spherical iron oxide pigment particles encapsulated by a layer of silicon dioxide enclosing the iron oxide pigment particle, wherein the silicon dioxide encapsulant is about 3 wt % to about 12 wt % by weight of the encapsulated iron oxide pigment particles,
wherein the spherical iron oxide pigment particles have a mean average particle size of from about 1 micron to about 10 microns.
