Abstract
Disclosed herein are ultraviolet (UV) filter compositions and methods relating to their preparation and use. The compositions and related method of preparation may include combining at least one or at least two UV filters with at least one other ingredient, wherein each of the UV filters is selected to have an overall environmental hazard score of 1.5 to 7.0, and determining an ecotoxicological value of the composition, wherein the ecotoxicological value ranges from 0 to 350.

A method of formulating a composition, comprising:
- combining at least one or at least two ultraviolet (UV) filters with a at least one other ingredient, wherein each of the UV filters is selected to have an overall environmental hazard score of 1.5 to 7.0;
- and
- determining an ecotoxicological value of the composition, wherein the ecotoxicological value ranges from 0 to 350.
A method of formulating a composition, comprising:
- determining an environmental profile of each of a plurality of ultraviolet (UV) filters;
- determining an overall environmental hazard score of each UV filter;
- preparing the composition comprising at least two of the UV filters;
- and
- determining an ecotoxicological value of the composition.
A method of determining an ecotoxicological value of a composition, comprising:
