Description

Sunscreen having reduced tendency to stain textiles III

The present invention relates to methods and uses for facilitating the ability of cosmetic preparations comprising UV photoprotective filters to be washed out from textiles, characterized in that one or more complexing agents are added to the cosmetic.

The trend away from pale complexion towards "healthy, athletic tanned skin" has continued for many years. To achieve this, people expose their skin to solar radiation since this causes pigment formation in terms of melanin formation. However, the ultraviolet radiation of sunlight also has a harmful effect on skin. In addition to the acute damage (sunburn), long-term damage, such as increased risk of suffering from skin cancer, occurs on excessive irradiation with light from the UVB region (wavelength: 280-320 nm). Excessive exposure to UVB and UVA radiation (wavelength: 320-400 nm) additionally 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 aging of the skin.

To protect the skin, a series of photoprotective filter substances have therefore been developed which may be used in cosmetic preparations. In the majority of industrialized countries, these UVA and UVB filters are compiled in the form of positive lists, such as annex 7 to the German Cosmetics Regulation.

The plethora of commercially available sunscreens should not however obscure the fact that these preparations from the prior art have a series of disadvantages.

Cosmetic preparations, such as sunscreen preparations which are applied to the skin, regularly come into contact (intentionally or unintentionally) with clothing and linen (e.g. towels) to which they remain partly adhered (e.g. by "abrasion" or because they are "absorbed" by the fibrous material). In this manner, depending on the type of ingredients, stains and discolorations are formed, especially on light-colored textiles. These discolorations are particularly caused by non-water-soluble UVA and broadband filters. The stains are difficult to remove by washing with conventional detergents and reinforced even more during the washing process by interactions with ions in the washing water.

The object of the present invention, therefore, was to overcome the disadvantages of the prior art and to develop a cosmetic preparation (especially a sunscreen) comprising non- water-soluble UVA filters and/or broadband filters, which can be more easily washed out of textiles contaminated with the preparation.

Surprisingly, the object is achieved by a method for facilitating the ability of cosmetic preparations comprising UV photoprotective filters to be washed out from textiles, characterized in that one or more complexing agents are added to the cosmetic.

Surprisingly, the object is achieved by a method for reducing the textile staining caused by cosmetic preparations comprising UV photoprotective filters, characterized in that one or more complexing agents are added to the cosmetic.

Surprisingly, the object is achieved by the use of complexing agents in cosmetic preparations comprising UV photoprotective filters for facilitating the ability of UV photoprotective filters to be washed out from textiles contaminated with the preparations.

Surprisingly, the object is achieved by the use of complexing agents in cosmetic preparations comprising UV photoprotective filters for reducing the textile staining caused by the preparation.

O It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.

Although W02011/101250 is known to those skilled in the art, this document could not have indicated the approach of the present invention.

The preparation according to the invention may also comprise the customary ingredients and have been combined as a customary preparation.

Comparativeexperiment

The effect in accordance with the invention can be substantiated with the following experiment by way of example: In each case, 1% auxiliary according to the invention was added to a formulation comprising 4-(tert-butyl)-4'-methoxydibenzoylmethane (INCI Butyl Methoxydibenzoylmethane) and the stain-reducing effect (reduction b*) compared to a formulation without complexing agent according to the invention was determined by the methods described.

As evidence of the improved ability to be washed out and reduced stain formation of the preparations according to the invention, in vitro investigations were conducted of which the results are presented in Figure 1 and Table 1. Various sunscreen emulsions were investigated with respect to the formation of yellow stains by means of an in vitro application/wash cycle. White pre-washed cotton monitors (100% cotton) were used here. For this purpose, 25 mg of the test formulation were distributed uniformly on PMMA Sch6nberg plates (5.0 x 5.0 cm) and transferred directly to the test textile by pressure. The stained cotton samples were then dried in air under laboratory conditions for 12 h. After drying, a colorimetric characterization of the resulting initial staining was carried out by measuring the degree of yellowing using the spectro-color colorimeter (Dr. Lange); color measurement software: spectral-QC, version measurement geometry: d/8 0 , gloss component excluded, type of light: D65 (corresponding to average daylight), calibration standard: LZM 268, measurement aperture: 10mm, sample background: substrate paper without optical brightener, test climate: 21C (±1°C), 41% (±4%)rel. atmospheric humidity. For the evaluation, the change in the b value from the CIE-Lab color measurement system was used. The B axis in the CIE-Lab system characterizes the yellow/blue color impression, where positive b values stand for an increase in the yellow fraction. The higher the b value, the greater the yellow impression. After the measurement procedure, a separate washing of the test cloths was carried out in the dye- and washing-fastness device Linitest Plus (Atlas) (600C, 1 h, 20 rpm, Ariel Compact powder detergent, 10 metal balls as ballast) and then a rinsing procedure (20°C, 15 min, tap water). After drying for 12 h under laboratory conditions, a colorimetric characterization of the resulting staining was carried out again by measuring the color values as already described using the spectro-color colorimeter (Dr. Lange).

The CIE-Lab system or L*a*b* color space is a three-dimensional measurement space in which all perceivable colors are contained. The color space is constructed on the basis of the opponent color theory. One of the most important properties of the L*a*b* color model is its instrument independence, i.e. the colors are defined independently of the nature of their production and display technology. The corresponding EU guideline is DIN EN ISO 11664-4 "Colorimetry - part 4: CIE 1976 L*a*b* color space". The coordinates of the CIELAB plane are formed from the red/green value a and the yellow/blue value b. The lightness axis L stands perpendicular to this plane. According to DIN 6174, L, a and b should be written with * in order to differentiate them from others, e.g. the "Hunter-Lab" system.
