- the present invention is also directed to a use of a cosmetic composition for providing dark color shades, and to processes for manufacturing a cosmetic composition for providing dark color shades.
- the composition for providing dark color shades of the present invention is suitable for skin phototypes 5 and 6.
- a phototype 1 of said scale is associated with very light skin, red or blonde hair, blue or green eyes, and a skin that always burns and/or never tans in the sun
- phototype 5 is commonly associated with dark brown skin, dark brown or black hair, brown eyes and tan easily and a skin that rarely burns when exposed to the sun
- phototype 6 is commonly associated with black skin, black hair, dark brown eyes and a skin that does not burn when exposed to the sun.
- UVA/UVB cosmetic sunscreen compositions used to accomplish photoprotection, namely, inorganic UV filters and organic UV filters.
- the degree of UV protection afforded by a cosmetic composition is directly related to the amount and type of UV filters contained therein.
- cosmetic sunscreen compositions must provide good protection against the sun, a measure of which is the Sun Protection Factor (SPF) value, a desirable balance between UVA and UVB protection, particularly a minimum UVA protection factor, yet have satisfactory sensory perception, such as a smooth and dry touch but not greasy feel upon application.

- additional mineral pigments that are useful in the present invention, mention may be made of zirconium oxide or cerium oxide, and also zinc oxide, additional iron oxides (i.e. , different than yellow, red and black iron oxides) or chromium oxide, manganese violet, ultramarine blue, chromium hydrate and ferric blue, and metal powders, for instance aluminium powder and copper powder.
- the following mineral pigments may also be used: Ta2Os, TisOs, Ti20s, TiO, ZrC as a mixture with ZrC , Nb20s, CeO2, ZnS.
- titanium dioxide used as a pigment
- UV-filter titanium dioxide the titanium dioxide used as a UV filter
- Titanium dioxide can form several different shapes, which have different properties. Particularly, the main difference between the pigment titanium dioxide and the UV-filter titanium dioxide is their particle size, being the pigment bigger than the UV-filter. At small sizes and at low concentrations, titanium dioxide appears as a minimal or nonwhite residual, allowing for effective sunscreens that do not appear white.
- Pigment titanium dioxide is the most widely used white pigment because of its brightness and very high refractive index, in which it is surpassed only by a few other materials. Pigment titanium dioxide crystal size is ideally bigger than 220 nm, even reaching a micrometric scale, such as about 7.000 nm (measured by electron microscope) to optimize the maximum reflection of visible light. Pigment titanium dioxide is also an effective opacifier in powder form, where it is employed as a pigment to provide whiteness and opacity to products such as paints, coatings, plastics, papers, inks, foods, medicines (i.e. pills and tablets), and most toothpastes. Pigment titanium dioxide is able to scatter the light, making it of more use for pigments.
- nanosized titanium dioxide which should herein also be considered as a synonym to “UV-filter titanium dioxide”, is found in the majority of physical sunscreens because of its strong UV light absorbing capabilities and its resistance to discoloration under ultraviolet light. This advantage enhances its stability and ability to protect the skin from ultraviolet light. Nano-scaled (particle size smaller than 200 nm) titanium dioxide particles are primarily used in sunscreen compositions because they scatter visible light much less than titanium dioxide pigments and can give UV protection.
- the cosmetic composition for providing dark color shades is substantially free of pigment titanium dioxide, but the composition may comprise titanium dioxide as a UV filter.
