Abstract

Abstract Method and use to facilitate the washability of cosmetic preparations containing UV filters out of textiles, characterized in that polyvinyl alcohol is added to the cosmetic.

Description

The present invention relates to methods and applications for facilitating the washing of cosmetic preparations containing UV filters out of textiles, characterized in that polyvinyl 5 alcohol is added to the cosmetic.
Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
The trend away from mainly pale skin toward a healthy, athletically tan skin has been uninterrupted for many years. To achieve such a tan, people expose their skin to sunlight because this causes a pigment to form in the skin in the sense of formation of melanin. However, the ultraviolet radiation of sunlight also has a damaging effect on skin. In addition 5 to acute damage (sunburn), there is also long-term damage, such as an increased risk of developing skin cancer from excessive exposure to light from the UVB range (wavelength: 280-320 nm). In addition, excessive exposure to UVB and UVA radiation (wavelength: 320400 nm) results in a weakening of the elastic and collagen fibers of the connective tissue. This results in numerous phototoxic and photoallergic reactions and causes premature aging 0 of skin.
Therefore, to protect skin, a number of sunscreen filter substances have been developed, which can be used in cosmetic preparations. In most industrial countries, these UVA and UVB filters have been compiled in the form of positive lists, such as Annex 7 of the [German]
Cosmetics Regulations.
However, the variety of sunscreens available commercially must not make us overlook the fact that these state-of-the-art preparations have a number of disadvantages.
Cosmetic preparations such as sunscreen preparations that are applied to skin frequently (intentionally or unintentionally) come in contact with items of clothing and laundry items (towels, for example) to which some of them adhere (for example, as abrasion or because they are absorbed by the fiber materials). In this way, depending on the type of ingredients, stains and discolorations are formed on light textiles in particular. These discolorations are caused by non-water-soluble UVA filters and broadband filters in particular. These stains are hard to remove by washing with traditional detergents and may even become more intense during the washing process due to interactions with ions in the wash water.
2017204073 16 Jun 2017
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.
The object of a preferred embodiment of the present invention is to find ways to make it easier to wash a cosmetic preparation (in particular a sunscreen) containing non-watersoluble UVA filters and/or broadband filters out of textiles contaminated with the preparation.
According to a first aspect of the present invention, there is provided a method for facilitating the washing of cosmetic preparations containing UV filters out of textiles, wherein polyvinyl alcohol is added to the cosmetic.
According to a second aspect of the present invention, there is provided a method for reducing the textile staining caused by cosmetic preparations containing UV filters, whereinpolyvinyl alcohol is added to the cosmetic.
According to a third aspect of the present invention, there is provided a use of polyvinyl alcohol in cosmetic preparations containing UV filters to facilitate washing the UV filters out of textiles contaminated with these preparations.
According to a fourth aspect of the present invention, there is provided a use of polyvinyl alcohol in cosmetic preparations containing UV filters to reduce the textile staining caused by the preparation.
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”.
In the technical world, the use of polyvinyl alcohol in sunscreens has been considered repeatedly. Thus, for example, DE 102005059742, WO 2014/102050 and US 2004/0126339 disclose the possibility of incorporating polyvinyl alcohol into sunscreens. Nevertheless, these publications could not have pointed the way to the present invention because the effect of the polyvinyl alcohol on washability was not recognized.
According to the invention, advantageous embodiments of the present invention are characterized in that the polyvinyl alcohol has a degree of hydrolysis (degree of
2017204073 16 Jun 2017 saponification) of 86 to 89 mol%. Therefore, a degree of hydrolysis (degree of saponification) of 86.7 to 88.7 mol% is preferred according to the invention.
In addition, it is advantageous according to the invention if the polyvinyl alcohol has a viscosity of 3 to 50 mPas, measured according to DIN 53015 (4% aqueous solution at 20°C).

Comparative Experiment/Exemplary Embodiment
Comparative Experiment
The effect according to the invention can be documented with the following experiment as an example:
The polyvinyl alcohols according to the invention were added to a formulation containing butyl methoxydibenzoylmethane and bis-ethylhexyloxyphenol methoxyphenyl triazine, and the stain-reducing effect (reduction db) was determined by means of an in vitro washing method in comparison with that of a formulation without the additives according to the invention.
To document the improved washability and reduced staining of the preparation according to the inventions, in vitro experiments were conducted, with the results summarized in Tables 1 and 2.
Various sunscreen emulsions were tested with regard to the formation of yellow stains over an in vitro application/wash cycle. White prewashed cotton monitors (100% cotton) were used. 50-mg portions of the test formulation were distributed uniformly on Schonberg PMMA plates (5.0 x 5.0 cm) and transferred directly to the test textile by means of contact pressure. Next, the stained cotton samples were dried in air for 12 hours under laboratory conditions.
After drying, a colorimetric characterization of the resulting initial staining was determined by measuring the degree of yellowness using the Spectro-color colorimeter (Dr. Lange); color measurement software: spectral QC, version measurement geometry: d/8°, glass component excluded, type of light: D65 (corresponding to average daylight), calibration standard: LZM 268, measurement aperture: 10 mm, sample background: substrate paper without optical brightener, test climate: 21 °C (± 1°C), 41% (± 4%) relative atmospheric humidity.
The change in the b value from the CIE-Lab color measurement system was used for the evaluation. The B axis characterizes the yellow/blue color impression in the CIE-Lab system, where positive b values indicate an increase in the yellow component. The higher the b value, the greater is the impression of yellowness.
A separate washing of the test fabrics was performed in a Linitest Plus (Atlas) colorfastness and washfastness testing device (60°C, 1 h, 20 rpm, Ariel Compact powder detergent,
10 metal balls as an additional load), and following that, a rinsing operation was carried out (20°C, 15 min, tap water).
After drying for 12 hours under laboratory conditions, a colorimetric characterization of the resultant staining was again determined by measuring the color values using the Spectrocolor colorimeter (Dr. Lange) as described above.
2017204073 16 Jun2017
The CIE-Lab system or L*a*b* color space is a three-dimensional measurement space containing all perceptible colors. This color space is constructed on the basis of the theory of opposite colors. One of the most important properties of the L*a*b* color model is that it is independent of the instrument. In other words, the colors are defined independently of how they are produced and the technique by which they are reproduced.
The corresponding EU guideline is DIN EN ISO 11664-4 Colorimetries - Part 4: CIE 1976 L*a*b* Color Space. The coordinates of the CIELAB plane are from the red/green value a and the yellow/blue value b. The lightness axis L is perpendicular to this plane. According to
DIN 6174, L, a and b are to be written with asterisks (*) to differentiate them from other systems, for example, the Hunter Lab system.
