Claims (31)

1. A composition comprising a sunscreen composition, the sunscreen composition comprising:

a. first flexible cellulose derived capsules encapsulating a first sunscreen composition comprising octocrylene and avobenzone;

b. second flexible cellulose derived capsules encapsulating a second sunscreen composition comprising octinoxate;

c. at least 10% (w/v) of one or more anionic surfactant that includes a sulfate;

d. about 1% (w/v) to about 10% (w/v) of a zwitterionic surfactant that includes a betaine; and

e. about 0.1% to about 10% of a polyquaternium;

wherein the first and second flexible cellulose derived capsules consist of i) cellulose, ethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, carboxymethylcellulose, a derivative of cellulose, a derivative of hydroxypropylcellulose, a derivative of hydroxypropylmethylcellulose, a derivative of ethylcellulose, a derivative of carboxymethylcellulose, or any combination thereof, and ii) the encapsulated first or second sunscreen composition, respectively; and

wherein the first and second flexible cellulose derived capsules have a mean diameter of about 200 nm to about 750 nm; and

wherein the composition has an SPF of at least about 20.

2. The composition of claim 1 , wherein the amount of octinoxate is from about 2% (w/v) to about 10% (w/v).

3. The composition of claim 1 , wherein the amount of octinoxate is about 10% (w/v).
