Description

COSMETIC SUNSCREEN COMPOSITIONS AND USE OF A COSMETIC SUNSCREEN COMPOSITION FIELD OF THE INVENTION The present invention is directed to a cosmetic sunscreen composition with light sensation and improved SPF, comprising (a) at least one polymer; (b) at least one filler; (c) at least one surfactant; (d) at least one fatty compound; and (e) at least one organic UV filter. The invention is also related to the use of the cosmetic sunscreen composition. BACKGROUND OF THE INVENTION The photoprotection of keratinous materials, is considered of great importance in order to protect from sun-damage, sunburn, photo-aging, as well as to decrease the chances of skin cancer development caused by exposure to ultraviolet (“UV”) radiation. There are typically two types of UVA/UVB sunscreen compositions used to accomplish photoprotection, namely, inorganic UV filters and organic UV filters. Consumers are concerned with the negative effects of the sun exposition, particularly the hazardous effects of exposure to ultraviolet (“UV”) light. Prolonged exposure to sunlight causes damage, such as sunburn, to the skin. When skin is exposed to UV light having a wavelength of from about 290 nm to about 400 nm, longterm damage can lead to serious conditions, such as skin cancer. UV light also contributes to aging by causing free radicals to form in the skin. Free radicals include, for example, singlet oxygen, hydroxyl radical, the superoxide anion, nitric oxide and hydrogen radicals. Free radicals attack DNA, membrane lipids and proteins, generating carbon radicals. These in turn react with oxygen to produce a peroxyl radical that can attack adjacent fatty acids to generate new carbon radicals. This cascade leads to a chain reaction producing lipid peroxidation products. Damage to the cell membrane results in loss of cell permeability, increased intercellular ionic concentration, and decreased ability to excrete or detoxify waste products. The end result is a loss of skin elasticity and the appearance of wrinkles. This process is commonly referred to as photo-aging. In this sense, in a skin care regimen, consumers apply cosmetic sunscreen compositions to protect the skin and the perception of the product on the skin is very important. Consumers are increasingly looking for cosmetic sunscreen products that are easy to apply, preferably with fluid/light properties that fit into their photoprotection routing while protect the skin with high degree of UV protection (UVA/UVB). This degree of UV protection of a cosmetic sunscreen composition is directly related to the amount and type of UV filters contained therein. The higher the amount of UV filters, the greater the degree of UV protection (UVA/UVB). Particularly, sunscreen compositions must provide good protection against the sun, a measure of which is the Sun Protection Factor (SPF) value, yet have satisfactory sensory perception, not greasy feel upon application. For said reasons, there is a need to develop new fluid/light cosmetic sunscreen compositions having the properties: high stability, greener ingredients, having good sensory properties, dry effect, having good absorption and spreadability and delivering high SPF. The inventors of the present invention have overcome the drawbacks of the state of the art and surprisingly achieved a fluid/light cosmetic sunscreen composition, comprising the properties mentioned above, with high SPF, good sensorial attributes, easy spreadability, light film, right level of radiance and skin feel, more sustainable ingredients and stability comprising: (a) at least one polymer; (b) at least one filler; (c) at least one surfactant; (d) at least one fatty compound; and (e) at least one organic UV filter. SUMMARY OF THE INVENTION The present invention is directed to new cosmetic sunscreens compositions with light sensation and improved SPF, comprising (a) at least one polymer; (b) at least one filler; (c) at least one surfactant; (d) at least one fatty compound; and (e) at least one organic UV filter, which surprisingly provides an unique lighter and faster absorbing and right level of radiance and skin feel, as well as an increase in the SPF properties in cosmetic sunscreen compositions. The present invention is also related to the use of the cosmetic sunscreen composition as sunscreen daily product. Other features and advantages of the present invention will be apparent from the following more detailed description of the desirable embodiments which illustrates, by way of example, the principles of the invention.
