A) at least one substance selected from the group consisting of desferrioxamines and acid addition products of a desferrioxamine or salt thereof, and

B) at least one UV light protection filter substance,

wherein component B) is present in an amount of 6.0% by weight to 60% by weight, the percentages by weight being with respect to a total composition.

2 : The composition according to claim 1 , wherein the desferrioxamine is selected from the group consisting of desferrioxamine A 1A , desferrioxamine A 1B , desferrioxamine A 2 , desferrioxamine B, desferrioxamine D 1 , desferrioxamine D 2 , desferrioxamine E, desferrioxamine Et 1 , desferrioxamine Et 2 , desferrioxamine Et 3 , desferrioxamine G 1 , desferrioxamine G 2A , desferrioxamine G 2B , desferrioxamine G 2C , desferrioxamine H, desferrioxamine N, desferrioxamine P 1 , desferrioxamine T 1 , desferrioxamine T 2 , desferrioxamine T 3 , desferrioxamine T 7 , desferrioxamine T 8 , desferrioxamine Te 1 , desferrioxamine Te 2 , desferrioxamine Te 3 , desferrioxamine X 1 , desferrioxamine X 2 , desferrioxamine X 3 , and desferrioxamine X 4 .

3 : The composition according to claim 1 , wherein the acid addition product of the desferrioxamine or salt thereof is an acid addition product of an acid selected from the group consisting of formic acid, aminooxyacetic acid, amino acids, anthraquinonecarboxylic acid, succinic acid, aqueous hydrochloric acid, acetic acid, folic acid, glutaric acid, hydroxamic acid, malonic acid, methanesulfonic acid, nalidixic acid, N-(methylamino)benzoic acid, phenylsuccinic acid, phenylglutaric acid, phosphorous acid, phosphoric acid, sulfurous acid, sulfuric acid, tartaric acid, and citric acid.

4 : The composition according to claim 1 , wherein component A) is present in an amount of 0.005% by weight to 10.0% by weight, the percentages by weight being with respect to the total composition.

5 : The composition according to claim 1 , wherein component B) comprises at least two UV light protection filter substances.

6 : The composition according to claim 1 , wherein component B) comprises an organic UV light protection filter substance.

7 : The composition according to claim 1 , wherein component B) comprises a UV light protection filter substance selected from the group consisting of

2,2′-[6-(4-methoxyphenyl)-1,3,5-triazine-2,4-diyl]bis{5-[(2-ethylhexyl)oxy]phenol},

2-ethylhexyl salicylate,

2,4,6-trianilino(p-carbo-2-ethylhexyl-1-oxy)-1,3,5-triazine,

hexyl 2-(4-diethylamino-2-hydroxybenzoyl)benzoate, and

1-(4-methoxyphenyl)-3-[4-(2-methyl-2-propanyl)phenyl]-1,3-propanedione.

8 : The composition according to claim 1 , wherein at least one further additional component is present, selected from the group consisting of emollients, emulsifiers, coemulsifiers, thickeners/viscosity regulators/stabilizers, antioxidants, hydrotropes (or polyols), solids, fillers, pearlescent additives, insect repellents, self-tanning agents, preservatives, conditioners, perfumes, colourants, cosmetic active substances, care additives, superfatting agents, and solvents.

9 : A process for decreasing discolourations of a textile caused by a sunscreen formulation, the process comprising:

forming the sunscreen formulation in the form of a composition containing

A) at least one substance selected from the group consisting of desferrioxamines and acid addition products of a desferrioxamine or salts thereof, and

B) at least one UV light protection filter substance,

and/or

in the form of the composition according to claim 1 .

10 : A method for decreasing discolouration of a textile caused by a sunscreen formulation containing at least one UV light protection filter substance, the method comprising:

adding at least one substance selected from the group consisting of desferrioxamines and acid addition products of a desferrioxamine or salts thereof, to the sunscreen formulation.

11 : A method for improving ability to wash out at least one UV light protection filter substance from a textile, the method comprising:

combing at least one substance selected from the group consisting of desferrioxamines and acid addition products of a desferrioxamine or salts thereof, with the at least one UV light protection filter substance.

12 : The composition according to claim 1 , wherein component B) is present in an amount of 10.0% by weight to 30% by weight.

13 : The composition according to claim 2 , wherein the desferrioxamine is selected from the group consisting of desferrioxamine B, desferrioxamine D 1 , desferrioxamine D 2 , desferrioxamine E, and desferrioxamine H.

14 : The composition according to claim 2 , wherein the desferrioxamine is selected from the group consisting of desferrioxamine B and desferrioxamine E.

15 : The composition according to claim 4 , wherein component A) is present in an amount of 0.1% by weight to 1.0% by weight.

16 : The composition according to claim 5 , wherein component B) comprises at least four UV light protection filter substances.

17 : The composition according to claim 6 , wherein the organic UV light protection filter substance is a triazine derivative.

18 : The process according to claim 9 , wherein the at least one substance is desferrioxamine B.

19 : The method according to claim 10 , wherein the at least one substance is desferrioxamine B.

20 : The method according to claim 11 , wherein the at least one substance is desferrioxamine B.
