SUNSCREEN COMPOSITIONS HAVING SYNERGISTIC COMBINATION OF UV FILTERS

摘要

The disclosure relates to sunscreen compositions having a synergistic combination of ultraviolet light (UV) filtering agents that provide a high sun protection factor (SPF). Compositions according to the disclosure have high SPF values without requiring high overall amounts of UV filtering agents. Furthermore, the disclosure relates to methods of using the described compositions for protecting keratinous substances such as skin and hair from UV radiation.

主权项

1. A sunscreen composition comprising the following combination of UV filters: octocrylene, butyl methoxydibenzoylmethane, bis-ethylhexyloxyphenol methoxyphenyl triazine, ethylhexyl triazone, and terephthalylidene dicampohor sulfonic acid; wherein the ratio of each filter relative to butyl methoxydibenzoylmethane is as follows:
the ratio of octocrylene to butyl methoxydibenzoylmethane is 0.8:1.0 to 1.6:1.0; the ratio of bis-ethylhexyloxyphenol methoxyphenyl triazine to butyl methoxydibenzoylmethane is 0.2:1.0 to 0.6:1.0; the ratio of ethylhexyl triazone to butyl methoxydibenzoylmethane is 0.3:1.0 to 0.6:1.0; and the ratio of terephthalylidene dicampohor sulfonic acid to butyl methoxydibenzoylmethane is 0.01:1.0 to 0.3:1.0.
