Description

Polysaccharide-containing sunscreen with reduced tendency to stain textiles

The present invention relates to the use of polysaccharides in cosmetic preparations containing UV filters to reduce the staining and/or discoloration of textiles brought about by the UV filters in the preparation and to make it easier to wash out the staining and/or discoloration of textiles brought about by the UV filters in the preparation, and to corresponding methods to facilitate washing out the stains.

The trend away from a distinguished pallor toward "healthy, sporty tan skin" has continued uninterrupted for years. People expose their skin to solar radiation to achieve it, since this induces the formation of pigment in the sense of melanin formation. However, the ultraviolet radiation in sunlight has a harmful effect on the skin. In addition to acute damage (sunburn), long-term damage occurs, such as an increased risk of contracting skin cancer from overexposure to light in the UVB range (wavelength: 280-320 nm). Moreover, excessive exposure to UVB and UVA radiation (wavelength: 320-400 nm) can weaken of the elastic and collagen fibers of the connective tissue. This leads to numerous phototoxic and photoallergic !0 reactions and results in premature aging of the skin.

For this reason, a number of photoprotective filter substances that can be incorporated into cosmetic preparations have been developed. In most industrialized countries, these UVA and UVB filters are summarized in the form of positive lists, such as annex 7 of the German Cosmetics Regulation.

Nevertheless, the multitude of commercially available sunscreens must not obscure the fact that these prior art preparations have several disadvantages.

Cosmetic preparations, like sunscreen formulations that are applied to the skin, regularly (intentionally or unintentionally) come into contact with clothing and laundry items (e.g. handkerchiefs), onto which they can partly adhere (e.g. by "rubbing off" or because they are "absorbed" into the fibers"). Depending on the contents, stains and discolorations can form in this way, especially on light textiles. These discolorations are produced primarily by water-insoluble UVA and broadband filters, in particular by the UV filters 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI: bis-ethylhexyloxyphenol methoxyphenyl triazine), 4-(tert.-butyl)-4'-methoxydibenzoylmethane

(INCI butyl methoxydibenzoylmethane) and (2-(4'-diethylamino-2'-hydroxybenzoyl)benzoic acid hexyl ester (INCI: diethylamino hydroxybenzoyl hexyl benzoate). The stains are difficult to remove by washing with conventional detergents and are even reinforced during the washing process as a result of interactions with ions in the washing water. The problem is especially prevalent in preparations with a high sun protection factor.

It was therefore the problem addressed by the present invention to eliminate the disadvantages of the prior art and to develop a cosmetic preparation (in particular a sunscreen) containing water-insoluble UVA filters, such as 4-(tert.-butyl)-4'-methoxydibenzoylmethane (INCI butyl methoxydibenzoylmethane) (INCI butyl bethoxydibenzoylmethane) and (2-(4'-diethylamino-2'-hydroxybenzoyl)benzoic acid hexyl ester (INCI: diethylamino hydroxybenzoyl hexyl benzoate), and broadband filters, such as bis-ethylhexyloxyphenol methoxyphenyl triazine, which are easier to wash out of textiles contaminated with the preparation.

According to a first aspect the invention provides the use of a polysaccharide in a cosmetic comprising a UV filter to reduce staining and/or discoloration of a textile brought about by the UV filter in the cosmetic, wherein the polysaccharide is a gum.

According to a second aspect the invention provides the use of a polysaccharide in a cosmetic preparation comprising a UV filter to facilitate washing out of staining and/or discoloration of a textile brought about by the UV filter in the cosmetic, wherein the polysaccharide is a gum.

!0 According to a third aspect the invention provides a method of washing a cosmetic comprising UV filters out of a textile, the method comprising the step of adding one or more polysaccharides to the cosmetic, wherein the one or polysaccharides are gums.

According to a fourth aspect the invention provides a method for reducing discoloration caused by cosmetic preparations comprising UV filters, the method comprising the step of adding one or more polysaccharides to the cosmetic, wherein the one or polysaccharides are gums.

In another aspect the invention also provides a cosmetic comprising a combination of a) 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI:bis-ethylhexyloxyphenol methoxyphenyl triazine) and b) welan gum and/or sclerotium gum.

In another aspect the invention also provides a cosmetic comprising a combination of 4-(tert.-butyl)-4'-methoxydibenzoylmethane (INCI butyl methoxydibenzoylmethane) and

I? welan gum and/or sclerotium gum.

In another aspect the invention also provides a cosmetic comprising a combination of (2-(4'-diethylamino-2'-hydroxybenzoyl)benzoic acid hexyl ester (INCI: diethylamino hydroxybenzoyl hexyl benzoate) and welan gum and/or sclerotium gum.

Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of "including, but not limited to".

The problem is solved in a surprising way by the use of polysaccharides in cosmetic preparations containing UV filters to reduce the staining and/or discoloration of textiles brought about by the UV filters in the preparation and by the use of polysaccharides in cosmetic preparations containing UV filters to make it easier to wash out of the staining and/or discoloration of textiles brought about by the UV filters in the preparation.

The problem is further solved in a surprising way by a method for facilitating washing cosmetic preparations containing UV filters out of textiles, characterized in that one or more polysaccharides are added to the cosmetic, and by a method for reducing the discoloration !0 caused by cosmetic preparations containing UV filters, characterized in that one or more polysaccharides are added to the cosmetic.

Although a person skilled in the art is thoroughly familiar with sunscreen containing polysaccharides, they have heretofore been employed to improve the sensory properties (powder raw materials) in the use of the products on the skin or to stabilize/thicken the formulations. However, the fact that polysaccharides exert an influence on undesirable textile staining and in particular that they lead to easier washability of the sunscreen and its UV filters out of the textiles was previously unknown and not to be expected.

In the context of the present disclosure, the phrases "according to the invention," "claimed preparation" etc. always refer to the claimed preparations, methods and uses, i.e. also to preparations in which the claimed uses are implemented and preparations with which the claimed method is implemented.

Comparative Test

It was possible to exemplify the claimed effect by means of the following test:

In each case, 1% of the claimed polysaccharides were added to a formulation containing butyl methoxydibenzoylmethanes or bis-ethylhexyloxyphenol methoxyphenyl triazine, and the stain-reducing effect (reduction b*) compared to a formulation without the claimed polysaccharides was ascertained by the described method. As evidence of the improved washability and reduced staining of the claimed preparations, in vitro studies were conducted, the results of which are shown in Tables 1 and 2.

Various sunscreen emulsions were tested for the formation of yellow stains over an in vitro application/washing cycle. White, pre-washed cotton monitors (100% cotton) were used for this process. Additionally, 25 mg of the test formulation was distributed evenly onto each of the Sch6nberg PMMA plates (5.0 x 5.0 cm) and transferred directly onto the test textile by pressure. The stained cotton samples were subsequently air-dried for 12 hours under laboratory conditions.

After drying, a colorimetric characterization of the resulting initial staining was carried out by measuring the yellowness with the spectro-color colorimeter (Dr. Lange); color measurement !0 software: spectral-QC, measurement geometry version: d/8°, gloss component excluded, light type: D65 (corresponding to medium daylight), calibration standard: LZM 268, measuring aperture: 10mm, sample background: backing paper without optical brighteners, testing atmosphere: 21 °C (±1°C), 41% (±4%) rel. humidity.

To perform the evaluation, the change in the b value is drawn from the CIE-Lab color-measuring system. The B axis characterizes the yellow-blue color impression in the CIE-Lab system, with positive b values standing for an increase in yellowness. The higher the b value, the greater the yellow impression.

Following the measurement process, the test cloths were washed separately in the Linitest Plus dyeing and color-fastness device (Atlas) (60°C, 1h, 20rpm, Ariel Compact detergent powder, ten metal balls as additional load), and then a rinse cycle was run (20°C, 15min, water from the main).

After drying for 12h under laboratory conditions, a colorimetric characterization of the resulting stains was again carried out by measuring the color values with the spectro-color colorimeter (Dr. Lange), as previously described.

The CIE-Lab system or L*a*b* color space is a three-dimensional measuring space containing all perceivable colors. The color space is constructed on the basis of the color opponent theory. One of the most important properties of the L*a*b* color model is its device independence; in other words, the colors are defined independently of the way in which they were generated and reproduced.

The corresponding EU Guideline is DIN EN ISO 11664-4: "Colorimetry - Part 4: CIE 1976 L*a*b* Colour Space". The coordinates of the CIELAB plane are formed from the red/green value a and the yellow/blue value b. The brightness axis L is on this plane. According to DIN 6174, the designations L, a and b should be written with * in order to differentiate them from other systems, e.g. the Hunter Lab system.
