Description

The invention encompasses the use of at least one compound selected from a group of compounds in order to improve the sun protection performance of cosmetic sunscreen preparations.

The skin is the largest organ in humans. Among its many functions (for example, for heat regulation and as a sense organ) is the barrier function, which prevents the drying of the skin (and thus ultimately the entire organism), probably the most important. At the same time, the skin acts as a protective device against the penetration and absorption of substances coming from outside.

Cosmetic skincare primarily means that the natural function of the skin acts as a barrier against environmental influences (eg dirt, chemicals, microorganisms) and against the loss of endogenous substances (eg water, natural fats, electrolytes) strengthened or restored.

In general, the light absorption behavior of sunscreen filter substances is very well known and documented, especially as in most industrialized countries there are positive lists for the use of such substances, which apply quite strict standards to the documentation. Depending on the area in which the UV light is absorbed, a distinction is made between UV-B filters, UV-A filters and broadband filters (which have a filtering effect over the entire range of UV-A and UV-B). By appropriate selection of the UV filter and its concentration in the sunscreen one has the opportunity to influence the degree of shielding of the UV light. For the dosage of the substances in the finished formulations, however, the absorbance values can at best provide orientation, since interactions with ingredients of the formulation or of the skin itself can lead to imponderables. Furthermore, it is usually difficult to estimate in advance how uniformly and in which layer thickness the filter substance is distributed in and on the horny layer of the skin.

In addition to the influence of the binding ability of the UV filter in or on the skin is of great importance for the water resistance of the formulation. It is understandable that oil-soluble UV filters are better bound to the (lipophilic) surface of the skin or are more difficult to wash off this than water-soluble UV filters.

The effectiveness of sunscreen or the underlying UV filter is usually determined in biological efficacy tests under standardized conditions.

The sun protection factor (SPF, often also called SPF (sun protection factor)) indicates the extension of the sun's rays, which is made possible by using the sunscreen. It is the ratio of erythema threshold with sunscreen and erythema threshold without sunscreen.

To test the UV-A protection performance, the IPD method is usually used (IPD immediate pigment darkening). Here, similar to the determination of the sun protection factor, a value is determined which indicates how much longer the skin protected by the sunscreen can be irradiated with UV-A radiation until the same pigmentation occurs as with the unprotected skin.

Another, Europe-wide established testing method is the Australian Standard AS / NZS 2604: 1997 , The absorption of the preparation in the UV-A range is measured. To meet the standard, the formulation must absorb at least 90% of the UV-A radiation in the 320-360 nm range.

UV radiation of different frequency / wavelength penetrates the tissue at different depths. Therefore, the type of damage is wavelength dependent. The UV-A protection is of particular importance here, since this UV radiation (UV-A (wavelength 315-400 nm), is essentially responsible for skin aging

UVA filters are among the chemical sunscreen filters. They penetrate the skin, absorb the high-energy UV radiation there and convert it into heat or light energy, which can no longer cause any damage. Although there is currently no approved test method for the determination of the UVA protective effect (in contrast to the COLIPA method for UVB filters), in practice the so-called UVA / UVB protective balance should apply.

In order to provide information on the UVA protection performance of a sunscreen product, various experimental models, both in vivo and in vitro, are used and statements derived therefrom met on the packaging (UVA protection to Australian standard, Persistant Darkening Factor & a). However, these figures are not comparable with each other. For this reason, the European Commission published a recommendation on September 22, 2006, which aims to increase the safety and transparency of sunscreen products. The EU recommendation provides 1/3 UVA protection in relation to UVB protection. So far, only the protection of sunburn-causing UVB rays was regulated in the Cosmetics Regulation. With the new EU recommendation, each sunscreen should simultaneously protect against UVA radiation. The consumer should assume that UVA protection is guaranteed, which increases with increasing SPF value. For ethical reasons, an in vitro method is proposed. Beiersdorf AG developed an in-vitro method for UVA determination as a function of the sun protection factor: the UVA / UVB balance. In February 2005, the UVA / UVB balance was declared as DIN 67502 published, making it the first official method for determining UVA protection in Europe. A method for measuring the UVA protection performance is also currently being worked on at COLIPA because the industry demands a uniform method. The COLIPA is the umbrella organization of the European cosmetics industry, it gives, among other things, recommendations regarding the execution of the measurement method. The UVA / UVB balance is the basis of the method discussed there. It is modified to include a pre-irradiation with UV light to include some special UV filter systems. So far, the products have been tested without pre-irradiation. As a result, no information could be provided as to whether the protective effect of the product under real conditions is given by sun exposure. This advanced measurement method is called "COLIPA Ratio".

This means that UVA filters are used in relation of 1: 3 to UVB filters and thus the UVA protection is raised with increasing light protection. The EU recommendation provides 1/3 UVA protection in relation to UVB protection. This measurement method is called "COLIPA Ratio". The COLIPA ratio must be according to the formula UVB / UVA <3

The COLIPA ratio is the standard for determining UVA protection.

EP 0887069 . EP 0887068 and EP 935959 reveal a UV-A boost through synthetic beeswax or natural beeswax. Boosting means an increase in performance over preparations without beeswax.

EP 1965871 discloses cosmetic preparations having a UV-A balance of greater than 35 containing one or more merocyanines.

Sunscreen formulations on the market often achieve adequate UV protection only by increased addition of UV filter substances.

This increased proportion of UV filter substances in turn leads to skin-friendlier preparations that feel dull and sticky, difficult to rub, more problematic to formulate and are not long-term stability.

It is desirable to provide preparations which, with the same UV filter content, provide improved sun protection without any disadvantages in other effects of the preparations.

An object of the present invention was therefore to remedy the disadvantages of the prior art.

Surprisingly, it has been found that selected active ingredients, lipids, waxes and emulsifiers are particularly effective UV-A SPF boosters. These substances significantly enhance the UV-A absorbing effect.

The invention is the use of at least one substance selected from the group Vitis vinifera seed oil (grapeseed oil), trimethylsiloxysilicate, talc, stearoxytrimethylsilane with stearyl alcohol, sodium polystyrene sulfonate, sodium hyaluronate, polysorbate 65, polysorbate 40, polymethylsilsesquioxane, phenethyl benzoate, ginkgo biloba Extract, Oenothera biennis (Evening Primrose Oil), Octadecenedioic Acid, Methyl Palmitate, Glycyrrhiza Inflata Root Extract, Glycine Soy (Isoflavone), Arctium Lappa Extract (VINYL), Diethylhexyl 2,6-Naphthalate, Ceramide 3, Caprylic / Capric Glycerides, Di-C12 -13 alkyl tartrate in Cosmetic or dermatological sunscreen preparations for improving the sun protection performance compared to the same preparations without this substance.

According to the invention, the improvement of the sun protection performance is understood to be the increase of the in-vitro SPF, UVA-SPF and / or Colipa Ratio measurement values.

In summary, from a number of different cosmetic ingredients, only the substances listed in the list have been identified to provide an effective increase in UV protection performance without increasing the level of UV protection filters. This common feature of enhancing the UV protection performance combines the selected fabrics without showing chemical or structural relationships.

The substances increase, increase the sunscreen of cosmetic or dermatological preparations. Although the preparations per se have a UV protection due to the UV filter contained, but this sunscreen is increased without increasing the proportion of the UV filters. The substances according to the invention are also referred to as boosters, SPF boosters due to their increase in performance, and the "increase" in light protection performance is also referred to as boosting or SPF boosting.

The following formulations A, B and C were prepared and their in-vitro SPF, UVA-SPF and Colipa ratio were measured or determined.

Preparation A is a preparation with corresponding UV filters but without the SPF booster according to the invention, B is the same preparation without UV filter and without SPF booster, preparations C are the respective preparations according to the invention with UV filter and SPF booster to a proportion of X. The differences in shares are each compensated by the share of water.
