[0003] Description

[0004] Cosmetic preparation for priming before applying make-up.

[0005] The present invention relates to a cosmetic O / W emulsion containing one or more UV filters, an emulsifier system, one or more oils selected from the group consisting of di(propylene glycol) dibenzoate (INCI: Dipropylene Glycol Dibenzoate), benzyl benzoate (INCI: Benzyl Benzoate) and C12-15 alkyl benzoate (INCI: C12-15 Alkyl Benzoate), wherein the preparation is free of polyacrylates, cross-linked acrylate / C10-C30 alkyl acrylate polymers, vinylpyrrolidone / hexadecene copolymers, 3-(4-methylbenzylidene) camphor, 2-hydroxy-4-methoxybenzophenone (INCI: Oxybenzone), 4-methoxycinnamate-2-ethylhexyl ester (INCI: Octylmethoxycinnamate), and ethylhexyl-2-cyano-3,3-diphenyl acrylate (INCI: Octocrylene). Parabens (especially methyl, propyl and butylparaben), methylisothiazolinone, chloromethylisothiazolinone, DMDM ​​hydantoin, mineral oils, mineral waxes and silicone oils, and their use.

[0006] The desire to look beautiful and attractive is rooted in human nature. Even though the ideal of beauty has changed over time, the pursuit of a flawless appearance has always been a human goal. The condition and appearance of the skin plays a significant role in achieving a beautiful and attractive appearance.

[0007] For the skin to fully perform its biological functions, it requires regular cleansing and care. Cleansing the skin removes dirt, sweat, and dead skin cells, which provide an ideal breeding ground for pathogens and parasites of all kinds. Skin care products primarily moisturize and replenish the skin's natural oils. They often contain active ingredients that regenerate the skin or protect it from the harmful effects of UV radiation. A third group consists of decorative cosmetics—that is, makeup products—which influence the appearance of the skin and enhance its visual appeal (e.g., lipsticks, mascara, foundations).

[0008] Difficulties in the application of cosmetics arise particularly when different products from these categories are to be combined.

[0009] Applying makeup to skin areas treated with skincare products presents a particular challenge. This is especially problematic when applying makeup to areas pre-treated with sunscreen, as the makeup does not adhere well to the sunscreen.

[0010] However, even on "untreated" skin, with its unevenness and color variations (for example, from age spots), makeup products often don't adhere evenly. For this reason, so-called "primer" preparations have been offered for several years. These form a kind of base on the skin, even out the complexion, and allow the subsequently applied makeup to truly shine. These "primer" preparations typically contain larger quantities of silicone oils, which enhances their cosmetic effect, but are increasingly viewed critically for environmental and resource conservation reasons. While silicone oils generally prevent the "white cast" of the product on the skin, they are not naturally occurring raw materials but must be synthetically produced. Consequently, they degrade slowly in the environment. For this reason, there is a growing interest in formulating cosmetic preparations without silicone oils.The object of the present invention was therefore to develop a silicone oil-free primer preparation that does not leave a white residue. "White residue" is understood by those skilled in the art to mean the formation of white streaks and residues on the skin during and after the application of a cosmetic preparation.

[0011] Furthermore, incorporating UV filters into primer formulations has proven difficult in the past. When using UV filters, it is desirable for a stable film (containing the UV filters) to remain on the skin. Primers, on the other hand, are intended to be absorbed quickly and completely into the skin. Since most UV filters are also organic compounds, their compatibility with the lipid phase of makeup products is often compromised. As a rule, the use of organic UV filters results in the makeup no longer adhering properly to the skin or flaking off relatively quickly.

[0012] The object of the present invention was therefore to develop a primrose preparation containing UV filters, on which make-up products can be applied well and evenly and adhere significantly more stably than on conventional primer products.

[0013] The tasks are surprisingly solved by a cosmetic O / W emulsion containing a) one or more UV filters,

[0014] b) an emulsifier system,

[0015] c) Di(propylene glycol) dibenzoate (INCI: Dipropylene Glycol Dibenzoate),

[0016] the preparation is free of polyacrylates, cross-linked acrylate / C 10-030 alkyl acrylate polymers, vinylpyrrolidone / hexadecene copolymers, 3-(4-methylbenzylidene) camphor, 2-hydroxy-4-methoxybenzophenone (INCI: oxybenzone), 4-methoxycinnamate-2-ethylhexyl ester (INCI: octyl methoxycinnamate), ethylhexyl-2-cyano-3,3-diphenyl acrylate (INCI: octocrylene), parabens (especially methyl, propyl, and butylparaben), methylisothiazolinone, chloromethylisothiazolinone, DMDM ​​hydantoin, mineral oils, mineral waxes, and silicone oils. The tasks are also surprisingly accomplished by using a cosmetic O / W emulsion containing

[0017] a) one or more UV filters,

[0018] b) an emulsifier system,

[0019] c) one or more oils selected from the group Di(propylene glycol) dibenzoate (INCI:
