SET OF CLAIMS

1 . A cosmetic composition comprising:

(a) at least 1 % by weight, based on the total weight of the composition, of at least one nonionic surfactant;

(b) at least 0.5% by weight, based on the total weight of the composition of a hydrophobic powder selected from the group consisting of silica aerogel and polylactic acid (PLA);

(c) at least 1 % by weight, based on the total weight of the composition, of at least one water-soluble polysaccharide chosen from starches; and

(d) UV filter system,

wherein the composition is in a soft-solid format.

2. The cosmetic composition, according to claim 1 , comprising from 1 % to 20% by weight of the at least one nonionic surfactant, based on the total weight of the composition.

3. The cosmetic composition, according to claim 1 , comprising from 1 % to 10% by weight of the hydrophobic powder, based on the total weight of the composition.

4. The cosmetic composition, according to claim 1 , comprising from 0.5% to 10% by weight of the at least one water-soluble polysaccharide, based on the total weight of the composition.

5. The cosmetic composition, according to claim 1 , wherein the UV filter system in the soft-solid cosmetic composition ranges from 0.1 % to 50% by weight, based on the total weight of the composition.

6. The cosmetic composition, according to claim 1 , wherein the at least one non-ionic surfactant is selected from the group consisting of steareth-2, steareth-20, glyceryl stearate, PEG-100 stearate and cetearyl alcohol.

7. The cosmetic composition, according to claim 1 , wherein the at least one water-soluble polysaccharide is selected from the group consisting of monostarch phosphates, distarch phosphates and tristarch phosphates.

8. The cosmetic composition, according to claim 7, wherein the at least one water-soluble polysaccharide is hydroxypropyl starch phosphate.

9. The cosmetic composition, according to claim 1 , wherein the UV filter system comprises at least one UV filter selected from the group of inorganic UV filters and organic UV filters.

10. The cosmetic 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; benzalmalonate 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.

1 1 . The cosmetic composition, according to claim 10, wherein the UV filter system comprises at least one organic UV filter selected from the group consisting of butyl methoxydibenzoylmethane, ethylhexyl salicylate, ethylhexyl triazone, octocrylene and homosalate.

12. The cosmetic composition, according to claim 1 1 , 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.

13. The cosmetic composition, according to claim 1 , further comprising fatty compounds selected from the group consisting of waxes, linear or branched C3-C40 hydrocarbons, or mixtures thereof.

14. The cosmetic composition, according to claim 13, wherein the fatty compounds in the soft-solid cosmetic composition ranges from 1 % to 30% by weight, based on the total weight of the composition.

15. The cosmetic composition, according to claim 1 , further comprising at least one anionic surfactant.

16. Use of a cosmetic composition comprising:

(a) at least 1 % by weight, based on the total weight of the composition, of at least one nonionic surfactant;

(b) at least 0.5% by weight, based on the total weight of the composition of a hydrophobic powder selected from the group consisting of silica aerogel and polylactic acid (PLA);

(c) at least 1 % by weight, based on the total weight of the composition, of at least one water-soluble polysaccharide chosen from starches; and

(d) UV filter system,

for the manufacture of a product to be used as sunscreen daily product, wherein the composition is in a soft-solid format.
