Definitions
- the present invention relates to a cosmetic preparation which is in the form of an aqueous preparation or an O / W emulsion containing particulate inorganic UV screening pigments having an average particle size of 10 to 500 nm, particulate organic UV photoprotective pigments in a total amount of at least 5 % By weight, based on the total weight of the preparation.
- UVA and UVB filters are summarized in most industrialized countries in the form of positive lists such as Appendix 7 of the German Cosmetics Regulation.
- the inorganic micropigments represent a special form of UV sunscreen filter substances.
- the UV protection effect of the micropigments is based on the physical effects of reflection and light scattering. In cosmetic preparations are called
- Wz patents-02123 inorganic micropigments usually pigments of titanium dioxide, zinc oxide or mixed oxides used with, for example, iron oxides.
- inorganic micropigments as UV filter substance in cosmetic preparations are mainly due to the fact that the pigments, in contrast to organic sunscreen filters, are physically and chemically very stable. They are not prone to decomposition or photoreactions even with strong UV radiation. Due to the
- a disadvantage of the prior art is the fact that inorganic micropigments are difficult to incorporate stably in cosmetic preparations.
- micropigments are used in higher concentrations (concentrations above 7% by weight, based on the total weight of the preparation), they form pigment agglomerates which precipitate out of the preparation relatively quickly. The storage stability is therefore low.
- W / O emulsion water-in-oil emulsion
- W / O emulsions because their outer phase is formed by the oil phase, usually have a rather oily-greasy skin feel.
- W / O emulsions with an increased content of inorganic micropigments have a ductile effect and are difficult to distribute on the skin.
- the formulations silicone oils must be added, which is often undesirable.
- O / W emulsions In the cosmetically-sensory-attractive oil-in-water emulsions (O / W emulsions), it has hitherto not been possible to incorporate large amounts of inorganic micropigments without avoiding the described disadvantages (for example lack of stability). At best, formulations with a low sun protection factor could be formulated in a stable manner. O / W sunscreen emulsions with a high SPF could, according to the prior art, only be achieved with the aid of liquid or dissolved organic sunscreen filters. In addition to the problem of skin penetration of these filters, the preparations have a greasy-sticky feel on the skin, especially at higher filter concentrations.
- the object of the present invention was therefore to eliminate the disadvantages of the prior art and to develop cosmetic sunscreens having a high SPF on an aqueous basis or on the basis of oil-in-water emulsions (O / W emulsions) whose UV Filter system based on micropigments.
- these preparations should be stable to storage and transport and should effectively suppress agglomeration of the micropigments during storage and use.
- the formulations should also have a stable absorption spectrum with a balanced UV-A / UV-B absorption balance when applied to the skin over a prolonged period of use.
- a cosmetic preparation which is in the form of an aqueous preparation or an O / W emulsion containing a) particulate inorganic UV photoprotective pigments having an average particle size of 10 to 500 nm, b) particulate organic UV photoprotective pigments in a total amount of at least 5% by weight, based on the total weight of the preparation.
