and the use of fatty alcohols to reduce textile stains caused by the sunscreen.

The trend away from the elegant pallor towards "healthy, sporty brown skin" has been going on for years. In order to achieve this, people expose their skin to the sun's radiation, since this causes pigment formation in the sense of melanin formation. However, the ultraviolet radiation from sunlight also has a damaging effect on the skin. In addition to acute damage (sunburn), long-term damage such as an increased risk of developing skin cancer occurs with excessive exposure to light from the UVB range (wavelength: 280-320 nm). The excessive exposure to UVB and UVA radiation (wavelength: 320-400 nm) also leads to a weakening of the elastic and collagen fibers of the connective tissue. This leads to numerous phototoxic and photoallergic reactions and results in premature skin aging.

To protect the skin, a number of light protection filter substances have therefore been developed that can be used in cosmetic preparations. These UVA and UVB filters are summarized in most industrialized countries in the form of positive lists such as Appendix 7 of the Cosmetics Regulation.

However, the large number of commercially available sunscreens must not hide the fact that these preparations of the prior art have a number of disadvantages.

Cosmetic preparations such as sunscreen preparations which are applied to the skin come into regular contact (intentionally or unintentionally) with items of clothing and laundry items (for example towels) on which they are applied (for example as “abrasion” or because they are “sucked up” by the fibers). partly stick. In this way, depending on the type of ingredients, stains and discolouration occur, especially on light textiles. These discolorations are caused in particular by non-water-soluble UVA and broadband filters such as 4- (tert-butyl) -4'-methoxydibenzoylmethane (INCI butyl methoxydibenzoylmethane), (2 - [- 4- (diethylamino) -2-hydroxybenzoyl] benzoic acid hexyl ester (INCI : Diethylamino hydroxybenzoyl hexyl benzoate) and 2,4-bis - {[4- (2-ethylhexyloxy) -2-hydroxy] phenyl} -6- (4-methoxyphenyl) -1,3,5-triazine (INCI : Bis-Ethylhexyloxyphenol Methoxyphenyl Triazin) The stains can hardly be removed by washing with conventional detergents and are even increased during the washing process due to interactions with ions in the washing water.

A number of solutions have been developed recently to get this textile staining problem under control by selecting certain ingredients for sunscreens. However, a disadvantage of these solutions is the fact that they are only effective in emulsion systems, but fail with gels and sprays based on ethanol. However, since these mostly transparent sunscreens are becoming increasingly popular with consumers, it was the object of the present invention to develop such an ethanolic sunscreen with a reduced tendency to stain textiles. In particular, the task was to develop an ethanol-based sunscreen with reduced textile staining, which one or more UV filters selected from the group of compounds 4- (tert-butyl) -4'-methoxydibenzoylmethane (INCI butyl methoxydibenzoylmethane), ( 2 - [- 4- (Diethylamino) -2-hydroxybenzoyl] benzoic acid hexyl ester (INCI: Diethylamino Hydroxybenzoyl Hexyl Benzoate) and 2,4-bis - {[4- (2-ethylhexyloxy) -2-hydroxy] phenyl} - 6- (4-methoxyphenyl) -1,3,5-triazine (INCI: bis-ethylhexyloxyphenol methoxyphenyl triazine).

2. b) Ethanol in einer Mindestmenge von 10 Gewichts-%, bezogen auf das Gesamtgewicht der Zubereitung,
3. c) einen oder mehrere Fettalkohole.

The task is solved by an ethanolic cosmetic sunscreen

1. a) one or more UV filters selected from the group of compounds 4- (tert-butyl) -4'-methoxydibenzoylmethane (INCI butyl methoxydibenzoylmethane), (2 - [- 4- (diethylamino) -2-hydroxybenzoyl] benzoic acid hexyl ester ( INCI: Diethylamino Hydroxybenzoyl Hexyl Benzoate) and 2,4-bis - {[4- (2-ethylhexyloxy) -2-hydroxy] phenyl} -6- (4-methoxyphenyl) -1,3,5-triazine ( INCI: bis-ethylhexyloxyphenol methoxyphenyl triazine),
2. b) ethanol in a minimum amount of 10% by weight, based on the total weight of the preparation,
3. c) one or more fatty alcohols.

The object is also achieved by the use of fatty alcohols in ethanolic, cosmetic sunscreens containing one or more UV filters from the group of compounds 4- (tert-butyl) -4'-methoxydibenzoylmethane (INCI butyl methoxydibenzoylmethane), (2- [ -4- (diethylamino) -2-hydroxybenzoyl] hexanoate (INCI: diethylamino hydroxybenzoyl hexyl benzoate) and 2,4-bis - {[4- (2-ethylhexyloxy) -2-hydroxy] phenyl} -6- ( 4-methoxyphenyl) -1,3,5-triazine (INCI: bis-ethylhexyloxyphenol methoxyphenyl triazine), to make it easier to wash out the UV light protection filter from textiles contaminated with the sunscreen.

The problem is also solved by the use of fatty alcohols in ethanolic, cosmetic sunscreens containing one or more UV filters from the group of compounds 4- (tert-butyl) -4'-methoxydibenzoylmethane (INCI butyl methoxydibenzoylmethane), (2- [-4- (Diethylamino) -2-hydroxybenzoyl] benzoic acid hexyl ester (INCI: diethylamino hydroxybenzoyl hexyl benzoate) and 2,4-bis - {[4- (2-ethylhexyloxy) -2-hydroxy] phenyl} -6- (4-methoxyphenyl) -1,3,5-triazine (INCI: bis-ethylhexyloxyphenol methoxyphenyl triazine), to reduce textile stains caused by the sunscreen.

The problem is solved not least by a process to facilitate the wash-out of UV filter residues from textiles which have been contaminated with an ethanolic, cosmetic sunscreen, the ethanolic sunscreen comprising one or more UV filters from the group of compounds 4- (tert-Butyl) -4'-methoxydibenzoylmethane (INCI butyl methoxydibenzoylmethane), (2 - [- 4- (diethylamino) -2-hydroxybenzoyl] hexanoate (INCI: diethylamino hydroxybenzoyl hexyl benzoate) and 2,4-bis - {[ 4- (2-ethyl-hexyloxy) -2-hydroxy] phenyl} -6- (4-methoxyphenyl) -1,3,5-triazine (INCI: bis-ethylhexyloxyphenol methoxyphenyl triazine), one or more fatty alcohols can be added.
