Description

Sunscreen protection means having polyglvceryl-10 stearate and polyclyceryl-2 cap rate

The present invention refers to a cosmetic preparation containing one or more UV-filters, polyglyceryl-10 stearate (INCI Polyglyceryl-10 Stearate) and polyclyceryl-2 caprate (INCI Polyglyceryl-2 Caprate), as well as to a method for increasing the washing-off capacity of UV filters from fabrics, which are contaminated by a cosmetic preparation, which contains said UV-A filters and/or wideband-filters, wherein polyglyceryl-10 stearate (INCI Polyglyceryl-10 Stearate) and polyclyceryl-2 caprate are added to the preparation and to the use of a mixture of polyglyceryl-10 stearate (INCI Polyglyceryl-10 Stearate) and polyclyceryl-2 caprate in cosmetic preparations containing UV-light protection filters for facilitating the washing off of the UV-light protection filters from the fabrics contaminated by said preparations.

The trend away from a posh paleness towards a "healthy, sporty brown skin" is a year-long undisputed tendency. In order to achieve this, people expose their skin to solar radiation, since it causes the formation of pigmentation in the form of melanin. The ultraviolet radiation of solar radiation however also has a damaging effect on the skin. Besides the acute damage (sunburn), also longer lasting damages such as an increased risk of skin cáncer in case of excessive irradiation by light in the UVB range (wavelengths: 280-320 nm) occur. The excessive action of UVB and UVA radiation (wavelengths: 320-400 nm) also causes a weakening of the elastic and collagen fibers of the connective tissue. This in turn causes several phototoxic and photoallergic reactions and a premature skin aging.

In order to protect the skin, a series of light protection filtering substances has been developed, which may be used in cosmetic preparations. These UVA and UVB filters generally are summarized in most industrial countries in positive lists such as in annex 7 of the cosmetic regulation.

The multitude of commercially available sunscreen means should however not hide the fact that these preparations of the state of the art are provided with a series of drawbacks.

Cosmetic preparations such as sunscreen preparations, which are applied on the skin, normally come into contact (whether voluntarily or not) with clothing and laundry articles (such as towels), on which they partially adhere (such as in the form of "abrasión material" or because they are "absorbed" by the fibrous materials). Thus, depending of the substances contained, in particular on bright colored fabrics, stains and discolorations are formed. These discolorations are in particular caused by non-water-soluble UVA- and wideband filters such as 4-(tert-butyl)-4'-methoxybenzobenzoylmethane (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-hydroxyphenyl]-phenyl} -6-(4-methoxyphenyl)-1,3,5-triazine (INCI: Bis-ethylhexyloxyphenol methoxyphenyl triazine). The stains are almost impossible to remove by conventional detergents and get even worse during the washing process due to interactions with ions in the washing water.

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

It was therefore the object of the present invention to elimínate the disadvantages of the prior art and to develop a cosmetic preparation (especially a sunscreen) containing non-water-soluble UV-A filters such as 4-(tert-butyl)-4'-methoxy-bisbenzoylmethane (INCI butyl methoxydibenzoylmethane) and (2-[-4-(diethylamino)-2-hydroxybenzoylj benzoic acid hexyl ester (INCI: diethylamino hydroxybenzoyl hexyl benzoate) and optionally containing wideband filters such as bis-ethylhexyloxyphenol methoxyphenyl triazines, which are easier to wash out from fabrics contaminated with the preparation.

In a first aspect the invention provides a cosmetic preparation containing: a) one or more UV filters, b) polyglyceryl-10 stearate (INCI polyglyceryl-10 stearate), c) polyclyceryl-2 caprate (INCI Polyglyceryl-2 Caprate).

In a second aspect the invention provides a method for increasing the washability of organic, oil-soluble UV-A filters and/or organic, oil-soluble wideband filters from fabrics, which are contaminated by a cosmetic preparation containing these UV-A filters and/or wideband filters, wherein polyglyceryl-10 stearate (INCI polyglyceryl-10 stearate) and polyclyceryl-2 caprate are added to the cosmetic preparation.

In a third aspect the invention provides a method for reducing the textile stains caused by cosmetic preparations containing the UV-protection filters, wherein polyglyceryl-10 stearate (INCI polyglyceryl-10 stearate) and polyclyceryl-2-caprate are added to the cosmetic.

Last but not least, in a fourth aspect the invention provides a mixture of polyglyceryl-10 stearate (INCI polyglyceryl-10 stearate) and polyclyceryl-2-caprate in cosmetic preparations containing a UV light protection filter to facilítate the washability of the UV light protection filter from the fabrics contaminated by the preparations.

Comparative test

By means of the following comparative test, the inventive effect could be confirmed by examples demonstrated. The following compositions were produced and the washability from fabrics was determined.

The following compositions were prepared:

Measurement of washability

The four sunscreen emulsions were tested with respect to the formation of yellow stains on cotton fabrics during an in vitro application/washing cycle. White pre-washed cotton monitors (100% cotton) were used.

To this end, 3 mg/cm2 of the test formulation was uniformly distributed over PMMA Schónberg plates (5.0 x 5.0 cm) and directly transferred by pressing onto the testfabric. The stained cotton specimens were subsequently air-dried under laboratory conditions for 12 hours.

After drying, a colorimetric characterization of the initial staining formed took place by measuring the degree of yellow by means of the DATACOLOR 800 (Datacolor International) color measurement apparatus.

Measurement geometry: d/8°, SCE (gloss component excluded)

Light type/observer; D65/10° (corresponding to average day light) UV-filtering: adapted to D65, Ganz/Griesser Method

Measurement opening: LAV (30 mm diameter)

Specimen background: base paper without optical highlighters, test climatic conditions: 21 °C (±1°C), 41% (±4%) relative humidity.

For evaluation purposes, the change of 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, wherein positive b valúes represent a yellow component increase. The higher the b valué, the stronger the yellowish impression.

After the measurement process, a sepárate washing of the test cloths took place in a washing machine (60°C, 2 hours, Ariel Compact powdery detergent, clean load).

After 12 hours drying under laboratory conditions, a new colorimetric characterization of the formed stains was performed by measuring the color valúes as already described, by using the DATACOLOR 800 (Datacolor International) color measurement apparatus.

The CIE-Lab system or L*a*b* color space is a three-dimensional measurement space in which all perceptible colors are contained. The color space is based on the theory of opposite colors. One of the most important properties of the L*a*b* color model is its apparatus-independence, i.e. colors are defined independently from the type of their production and reproduction technology.

The corresponding EU-directive is DIN EN ISO 11664-4 “Farbmetrik - Teil 4: CIE 1976 L*a*b* Farbenraum.” The coordinates of the CIELAB plañe are formed by red/green valué a and yellow/blue valué b. The luminosity axis L is perpendicular to this plañe. According to DIN 6174, L, a and b have to be written with an *, in order to distinguish them from other systems, such as the "Hunter-Lab" system.

Result

Conclusión: The cotton cloths having the preparations with polyglyceryl-2 caprate showed, after washing, a reduced yellow-coloring with respect to reference cotton cloths.
