SUNSCREEN COMPOSITIONS HAVING SYNERGISTIC COMBINATION OF UV FILTERS

摘要

The patent describes sunscreen compositions having a synergistic combination of ultraviolet light (UV) filtering agents that provide a high sun protection factor (SPF) without requiring high overall amounts of UV filtering agents. The patent claims various combinations of UV filters, which have been summarised in table 1. All the percentages are by weight relative to the total weight of the sunscreen composition and other combinations are suggested within the patent. It is claimed that such combinations deliver SPF values eight times the total percent of the UV filters, thus the percentage suggested may deliver SPF136.The patent claims ratios of the various UV filters shown in the table with reference to the value for avobenzone to deliver SPF values from 15-137.
