SET OF CLAIMS

1 . An anhydrous sunscreen composition, comprising:

(a) silica aerogel;

(b) liquid carnauba wax; and

(c) UV filter system.

2. The anhydrous sunscreen composition, according to the preceding claim, wherein the amount of silica aerogel in the sunscreen composition is from 1 % by weight to 10% by weight, relative to the total weight of the composition.

3. The anhydrous sunscreen composition, according to the preceding claim, wherein the amount of carnauba wax liquid emulsion in the sunscreen composition is from 1 % by weight to 10% by weight, relative to the total weight of the composition.

4. The anhydrous sunscreen composition, according to any one of the preceding claims, wherein the amount of UV filter system in the sunscreen composition is from 0.1 % by weight to 50% by weight, including all ranges and sub ranges there between, relative to the total weight of the composition.

5. The anhydrous sunscreen composition, according to any one of the preceding claims, wherein the silica aerogel is a hydrophobic silica aerogel.

6. The anhydrous sunscreen composition, according to any one of the preceding claims, wherein the UV filter system comprises at least one UV filter selected from the group of inorganic UV filters and organic UV filters.

7. The anhydrous sunscreen composition, according to claim 8, wherein the UV filter system comprises at least one organic UV filter selected from the group consisting of anthranilic compounds; dibenzoylmethane compounds; cinnamic compounds; salicylic compounds; camphor compounds; benzophenone compounds; b,b-diphenylacrylate compounds; triazine compounds; benzotriazole compounds; benzalrmalonate compounds; benzimidazole compounds; imidazoline compounds; bis-benzoazolyl compounds; p-aminobenzoic acid (PABA) compounds; methylenebis(hydroxyphenylbenzotriazole) compounds; benzoxazole compounds; screening polymers and screening silicones; dimers derived from a-alkylstyrene; 4,4-diarylbutadienes compounds; guaiazulene and derivatives thereof; rutin and derivatives thereof; flavonoids; bioflavonoids; oryzanol and derivatives thereof; quinic acid and derivatives thereof; phenols; retinol; cysteine; aromatic amino acids; peptides having an aromatic amino acid residue; and mixtures thereof.

8. The anhydrous sunscreen composition, according to claim 6, wherein the UV filter system comprises at least one inorganic UV filter selected from the group consisting of silicon carbide, coated or uncoated metal oxides, and mixtures thereof.

9. The anhydrous sunscreen composition, according to any one of the preceding claims, further comprising fatty compounds in an amount ranging from 10% by weight to 95% by weight, based on the total weight of composition.

10. The anhydrous sunscreen composition, according to claim 9, wherein the fatty compounds are selected from the group of oils, waxes, fatty acids, fatty alcohols, and mixtures thereof.

1 1 . The anhydrous sunscreen composition, according to any one of the preceding claims, wherein the composition is in the form of a stick.

12. A process of manufacturing an anhydrous sunscreen composition, comprising the steps of:

(a) melting and mixing of the fatty compounds, the UV filter system and the silica aerogel at a temperature ranging from 60 to 100°C;

(b) adding liquid carnauba wax to the mixture of step (a) at a temperature ranging from 60 to 100°C;

(c) optionally, incorporate additional ingredients to the mixture of step (b) at a temperature ranging from 60 to 100 °C.

13. An anhydrous sunscreen composition, obtained by the process as defined in claim 12.

14. Use of the anhydrous sunscreen composition, as defined in any one of claims 1 to 1 1 or 13, for the manufacture of a product to be used as sunscreen daily product.

15. Use, according to claim 14, wherein the sunscreen daily product is in the form of a stick.

16. Use of a liquid carnauba wax for manufacturing the anhydrous sunscreen composition as defined in any one of claims 1 to 1 1 and 13.
