Definitions
- 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 is primarily understood as strengthening or restoring the skin's natural function as a barrier against environmental influences (e.g., dirt, chemicals, microorganisms) and against the loss of endogenous substances (e.g., water, natural fats, electrolytes).
- environmental influences e.g., dirt, chemicals, microorganisms
- endogenous substances e.g., water, natural fats, electrolytes
- UV-B filters UV-A filters and broadband filters (which have a filtering effect over the entire range of UV-A and UV-B).
- UV-A filters UV-A filters
- broadband filters which have a filtering effect over the entire range of UV-A and UV-B.
- the absorbance values can at best provide orientation, since interactions with ingredients of the formulation or of the skin itself can lead to imponderables.
- UV filter 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.
- IPD immediate pigment darkening
- 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.
- 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 protection balance should apply.
- UVA protection 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 derived statements are made on the packaging (UVA protection according to
- 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".
- 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
- the COLIPA ratio is the standard for determining UVA protection.
- EP 0887069, EP 0887068 and EP 935959 disclose UV-A boosting
- Boosting means an increase in performance over preparations without
- 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.
- 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.
- An object of the present invention was therefore to remedy the disadvantages of the prior art.
- 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 tartrates in cosmetic or dermatological light protection preparations for improving the sun protection performance compared to the
- 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.
- UV filter-containing preparations which comprise one or more of the SPF boosters according to the invention, such as, for example, DE 102007005336 A1, DE 102007005335 A1, DE 102007005334 A1, EP 1728501 A1, EP 1342463 A1, WO 2006125676 A1 or WO 02/17873.
- DE 102007005336 A1, DE 102007005335 A1, DE 102007005334 A1, EP 1728501 A1, EP 1342463 A1, WO 2006125676 A1 or WO 02/17873 discloses the increase in light protection performance according to the invention on account of these individual substances.
- 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 due to their
- Increased performance also known as a booster, SPF booster and the "increase" of sunscreen performance as boosting or SPF boosting.
- 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 proportion of water.
- UVA-SPF column UVAPF Colipa after 13.3 4.4
- a colipa ratio of less than 2.3 means an increase in light protection performance over comparison preparation A.
- the compounds lead to SPF boosting (increase in the sun protection power), in the case of the substances from the group of lipids:
- Grapeseed oil-> SPF boosting by 46% For the substances from the group of waxes / stabilizers:
- SPF boosters show preparations in UV filter compositions in at least one measuring range selected from Colipa ratio, in vitro SPF or UVA-SPF, an increase in the sun protection power compared to the preparations without the SPF booster. It is advantageous to select those compounds, SPF boosters, which have an increased light protection performance in two or three measuring ranges. These are in particular Glycine Soy, Ceramide 3, Caprylic / Capric Glycerides, Polysorbate 65, Polysorbate 40, Tale and Sodium Polystyrene Sulfonate.
- the substances according to the invention for improving the sun protection performance are:
- SPF boosters increase the sun protection performance of UV filter-containing preparations by more than 8%, compared to the preparation without the SPF booster.
- the cosmetic or dermatological preparations contain UV filter substances.
- the proportion of UV-A filters is preferably 0.5 to 10 wt.%, Based on the total mass of the preparation.

- Color pigments, thickeners, moisturizing and / or moisturizing substances, fats, oils, waxes or other customary constituents of a cosmetic or dermatological formulation such as alcohols, polyols, polymers, foam stabilizers, electrolytes, organic solvents or silicone derivatives.
- Waterproof sunscreen formulations are usually achieved by using film formers.
- Film formers are characterized by the following property: If a film former is dissolved in water or other suitable solvents and the solution is then applied to the skin, then after the solvent has evaporated, a film is formed which essentially serves the light protection filter substances on the skin fix and above all to ensure or increase the water resistance of the preparation on the skin.
- Known film formers are, for example, polymers based on PVP (Antaron V216, V220 of GAF ChemiecalsCooperation), sodium polystyrene sulfonate (Flexan 130 of National Starch) or polyisobutene (Rewopal PIB 1000).
