Sunscreen compositions

1. A lip treatment formulation comprising a taste-masked sunscreen composition wherein the taste-masked sunscreen composition comprises at least one organic sunscreen, a spider ester, and at least one ingredient selected from the group consisting of ubiquinone, spilanthes acmella flower extract, hyaluronic acid, a hyaluronic acid salt, and mixtures thereof;

wherein the organic sunscreen and the spider ester are in intimate association;

the intimate association being achieved by mixing together the at least one organic sunscreen and the spider ester, and optionally a photostabilizer, to form a pre-mix prior to combining the pre-mix with any other ingredients of the composition;

wherein the at least one organic sunscreen is avobenzone;

wherein the ratio of the total amount of sunscreen to spider ester is from 0.6 to 2 by weight; and

wherein the spider ester has the common linking group of sorbitol.

2. The lip treatment formulation of claim 1 , wherein a short polyoxyalkene chain is attached to each oxygen atom of the common linking group.

3. The lip treatment formulation of claim 2 wherein the polyoxyalkene chain has oxyalkene units selected from ethylene oxide units, propylene oxide units and mixtures thereof and wherein the number of polyoxyalkene units in each chain is 1 to 5 units.

4. The lip treatment formulation of claim 1 further comprising a photostabilizer.

5. The lip treatment formulation of claim 1 , wherein the lip treatment formulation is an extensible and retractable lip balm stick.

6. The lip treatment formulation of claim 1 wherein the formulation further comprises a structurant selected from paraffin wax, carnauba wax, candelilla wax and mixtures thereof.

7. A method of taste-masking a sunscreen composition comprising:

combining at least one organic sunscreen with a spider ester in an intimate association;

wherein the at least one organic sunscreen is avobenzone;

wherein the ratio of the total amount of sunscreen to spider ester is from 0.6 to 2 by weight;

wherein the spider ester has the common linking group of sorbitol;

the intimate association being achieved by mixing together the at least one organic sunscreen and the spider ester and heating to a temperature of from about 40° C. to about 80° C.; and

optionally a photostabilizer;

to form a pre-mix prior to combining the pre-mix with any other ingredients of the composition; and

at least one ingredient selected from the group consisting of ubiquinone, spilanthes acmella flower extract, hyaluronic acid, a hyaluronic acid salt, and mixtures thereof.

8. The method of claim 7 wherein a short polyoxyalkene chain is attached to each oxygen atom of the common linking group.

9. The method of claim 8 wherein the polyoxyalkene chain has oxyalkene units selected from ethylene oxide units, propylene oxide units or a mixture thereof and wherein the number of polyoxyalkene units in each chain is 1 to 5 units.

10. The method of claim 7 further comprising combining the taste-masked composition with at least one melted structurant wax and forming a stick lip balm therefrom.

11. A lip treatment formulation comprising a taste-masked sunscreen composition wherein the taste-masked sunscreen composition comprises:

(a) at least one spider ester comprising about 5 to about 30% wt/wt of the composition;

(b) at least one skin protectant comprising about 0.15 to about 50% wt/wt of the composition;

(c) at least one organic sunscreen agent comprising about 3 to about 30% wt/wt of the composition;

(d) at least one photostabilizer comprising about 0.1 to about 5% wt/wt of the composition;

(e) at least one viscosity increasing agent comprising about 0.1 to about 30% wt/wt of the composition;

(f) at least one skin conditioning agent comprising about 1 to about 65% wt/wt of the composition;

(g) at least one antioxidant comprising about 0.1 to about 3% wt/wt of the composition;

(h) wherein the at least one organic sunscreen agent is avobenzone;

(i) wherein the ratio of the total amount of sunscreen to spider ester is from 0.6 to 2 by weight;

(j) wherein the spider ester has the common linking group of sorbitol; and

(k) wherein the spider ester and the organic sunscreen agent, and optionally the photostabilizer, are mixed together to form an intimate association prior to combining these ingredients with the other ingredients.

12. The lip treatment formulation of claim 11 wherein the taste-masked sunscreen composition further comprises a flavorant.

13. The lip treatment formulation of claim 11 wherein the taste-masked sunscreen composition further comprises a colorant.

14. The lip treatment formulation of claim 11 wherein the colorant contains titanium dioxide.
