A lip treatment formulation comprising a taste masked sunscreen composition wherein the taste-masked sunscreen composition comprises at least one organic sunscreen and a spider ester 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 about 0.6 to about 2 by weight;
- wherein the spider ester has the common linking group of sorbitol;
- and
- at least one ingredient selected from ubiquinone, spilanthes acmella flower extract, hyaluronic acid, a hyaluronic acid salt, and mixtures thereof.
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 about 0.6 to about 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 ubiquinone, spilanthes acmella flower extract, hyaluronic acid, a hyaluronic acid salt, and mixtures thereof.
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 about 0.6 to about 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.
