Abstract
Official abstract text for this publication.
The present invention relates to a personal care composition. More particularly the present invention relates to stabilization of UVA sunscreen dibenzoylmethane derivatives or even more particularly Parsol 1789™ (4-t-butyl-4′-methoxydibenzoylmethane) in personal care compositions. It is an object of the present invention to provide a personal care composition with relatively long photoprotection efficiency. It is another object of the present invention to stabilize Parsol 1789 by use of a natural substance or materials derived from plants. Surprisingly the present inventors have found that theaflavin or black tea extract having high levels of theaflavin, can act as a photostabilizer for dibenzoylmethane derivatives or Parsol-1789™.
First claim
Opening claim text (preview).
The invention claimed is: 1. A personal care composition comprising: i) a dibenzoylmethane derivative; ii) 0.1 to 30% by weight theaflavin; and, iii) a cosmetically acceptable base, wherein the cosmetically acceptable base is a water-in-oil emulsion. 2. A composition as claimed in claim 1 comprising 0.3 to 10% theaflavin. 3. A composition as claimed in claim 1 wherein the dibenzoylmethane derivative is 4-t-butyl-4′-methoxydibenzo…
