The present invention also relates to a method for inhibiting damage due to UV radiation on a keratinous substrate, in particular on the skin, by applying the photoprotective composition disclosed above to a surface of the keratinous substrate.

Detailed description of the invention

The present invention provides a sunscreen composition with high UV protection, SPF with water resistance, and broad spectrum protection with an SPF between about 30 and about 55. The sunscreen composition employs a hybrid UV filter system which features inorganic/mineral and organic UV filters, and features film forming agents and dispersing agents to achieve water resistance, and emulsifiers, solvents and structuring agents which provide the consumer with spreading properties and sensory acceptable to the user, including non-bleaching characteristics. The photoprotective composition is temperature stable with a fluid or cream-like water-in-oil emulsion structure, which after a while may have a slight separation on the surface, and is homogeneous after shaking at the time of application. application.

The term “keratinous tissue” includes, in particular, the skin, the hair and the nails.

The term "water-in-oil emulsion" or "W/O emulsion" comprises a water phase dispersed in an oil phase, where the oil phase is a continuous phase.

The term “homogeneous” means, in reference to the composition, to have an essentially uniform visual appearance, that is to say that visually there is no separation and accumulation of the fluid.

The term “sun protection index” or SPI is a value expressed mathematically by the ratio of the duration of irradiation necessary to reach the erythemogenic threshold with the anti-UV agent to the time necessary to reach the erythemogenic threshold without anti-UV agent. UV. the IPS generally gives information on the resistance of the skin to ultraviolet B (UVB) radiation emitted by the sun. The IPS Rating System was developed to provide consumer guidance on sunscreen selection. The photoprotective composition according to the present invention can be formulated to achieve a variety of different SPIs. For example, the photoprotective composition can have an in vitro SPF or in vivo SPF of at least 30, 35, 40, 45, 50, or 55 or more (or in a range between any two of these values).

The term “critical wavelength” is an absorption spectrum of a photoprotective composition characterized by an index, namely a wavelength, in which the integral of the spectral absorption curve has reached 90% of the integral between 290 nm and 400 nm. The critical wavelength is used to determine the width of UV protection. In some embodiments, the photoprotective composition has a critical wavelength that is at least 370 nm.

The terms "water-resistant broad-spectrum UV protection" and "water-resistant IPS" and "WR" generally refer to the preservation property of UV protection, for example, stable retention of IPS, after exposure to water under conditions with predetermined water exposure times. A composition exhibits SPF or UV protection with water resistance when the Water Resistant SPF maintains SPF after being submerged in a water base for 40-80 minutes. So, for example, a sunscreen composition can carry the WR designation if the sunscreen exhibits an SPI that has not diminished by more than 10% after application to a substrate and submersion in water for about 40 minutes and up to about 80 minutes.

The term "structural emulsion stability" means that a sunscreen composition exhibits the original aesthetic appearance, including the absence of a grainy texture and no visually perceptible separation of phases and exhibits no accumulation of fluid. Further, a photoprotective composition retains its stability during prolonged storage, including storage of up to four weeks or up to eight weeks, including exposure to temperatures of up to about 45°C. For example, a sunscreen composition is considered to exhibit structural emulsion stability if the composition does not show signs of phase separation and/or does not become inhomogeneous, particularly after exposure to about 45°C for about four at eight weeks and/or any inhomogeneity is easily resolved by shaking or shaking the composition. In certain embodiments of the photoprotective composition comprising powders, the photoprotective composition demonstrates structural stability of the emulsion in which it does not show any signs of phase separation, and/or does not become non-homogeneous, in particular after exposure at room temperature of about 5°C, about 25°C, or about 37°C or about 45°C for up to eight weeks and where any inhomogeneity is easily resolved by shaking or buying composition. In contrast, an emulsion that lacks structural stability exhibits inhomogeneity and phase separation either initially or after exposure to ambient temperatures of about 45°C for about four to eight weeks, and where the non-homogeneity is not easily resolved by shaking or agitating the composition.

The term "SPI enhancer" refers to a material that increases the UV absorption of another material when the two are mixed in a composition by refracting the UV radiation, thereby increasing the effective wavelength of the UV radiation through the photoprotective composition.

In the various embodiments, the photoprotective composition comprises

1. at least one mineral UV filter, present from about 10% to about 14%;
2. a mixture of organic UV filters, present from about 15% to about 45%;
3. at least one film former, present from about 2% to about 5%;
4. one or a combination of dispersing agents;
5. one or a combination of emulsifiers;
6. one or a combination of structuring agents;
7. one or a combination of solvents and
8. optionally one or a combination of SPI enhancers, a combination of sensory fatty compounds or feel modifying powders or one or a combination of active products.

While the invention has been described with reference to a preferred embodiment, those skilled in the art will understand that various changes may be made and equivalents may be substituted for elements herein without departing from the scope of the invention. . Furthermore, many modifications can be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope of the latter. Accordingly, it is understood that the invention is not limited to the particular embodiment disclosed as the best mode contemplated for carrying out the invention but that the invention shall include all embodiments falling within the scope of the appended claims.

The use of "a" and "an" does not limit the meaning to a single characteristic unless a limit is specifically stated. The article "the" preceding singular or plural nouns or nouns denotes a particular specified characteristic or particular specified characteristics and may have a singular or plural connotation depending on the context in which it is used. The adjective "all" denotes one, some or whatever quantity.

"At least one" or "one or more" "a combination of" or "more than one" as used herein means that there may be 1,2, three or more and therefore includes the individual components as well as mixtures/combinations of components.

The transitional terms "comprising", "consisting essentially of" and "composed of", when used in the appended claims, in original and amended form, define the scope of the claim with respect to the elements or steps of additional claims not cited, where appropriate, are excluded from the scope of the claim(s). The term "including" is intended to be inclusive or open-ended and does not exclude any additional, unlisted elements, methods, steps, materials. The term "consisting of" excludes any element, step or material other than those specified in the claim and, ultimately, impurities ordinarily associated with the specified material(s). The phrase "consisting essentially of" limits the scope of a claim to specified elements, steps or materials and to those that do not significantly affect the basis and innovative features of the claimed invention. All materials and methods described herein that embody the present invention may, in other embodiments, be more specifically defined by any transitional terms such as "comprising", "consisting essentially of", and "composed of". .

The terms "free from" and "free from" indicate that no reliably measurable excluded material is present in the sunscreen composition, generally 0% by weight, based on the total weight of the sunscreen composition. The term "substantially free of" means that, while it is preferred that no excluded material be present in the sunscreen composition, it is possible that there are very small amounts of the excluded material in the sunscreen composition of the invention, provided that these amounts do not significantly affect the advantageous properties of the photoprotective composition. In particular, "substantially free of" means that the excluded material may be present in the photoprotective composition in an amount less than about 0.1% by weight, based on the total weight of the photoprotective composition.

Other than in the working examples, or unless otherwise indicated, all numbers expressing quantities of ingredients and/or process conditions must be understood as being modified, in all cases, by the term "approximately", at 10% near the number shown (for example, about 10% means 9-11% and about 2% means 1.8-2.2%.

All percentages and ratios are calculated, unless otherwise stated, by weight. All percentages are calculated based on total composition, unless otherwise stated. In general, except as expressly provided herein, "weight" or "quantity" as used herein in relation to a percentage of ingredients refers to the quantity of raw material comprising the ingredient or the material The first can be described herein as having less than and up to 100% activity of the ingredient. Therefore, the weight percentage of an active in a composition is represented as the amount of raw material containing the active that is used and may or may not reflect the final percentage of the active; in which the final percentage of the asset depends on the weight percentage of the asset in the raw material.

All ranges and amounts given herein are understood to include sub-ranges and amounts using any point disclosed as an end point. Accordingly, a range of "1% to 10%, such as 2% to 8%, such as 3% to 5%," is intended to encompass the ranges of "1% to 8%", "1% to 5% », « 2% to 10% », etc. All numbers, quantities, ranges etc. are understood to be modified by the term “approximately” whether or not expressly stated. Similarly, a given range of "about 1% to 10%" is understood to have the term "about" modifying both endpoints by 1% and 10%. Furthermore, it is understood that when a quantity of a component is indicated, it is understood to mean the quantity of active material, unless otherwise indicated.

Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, unless otherwise indicated, the numerical values given in the specific examples are given as accurately as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective measurements. The following example serves to illustrate embodiments of the present invention; however, being limited in nature.
