Croda answers this market need with its U.S. launch of Chromaveil, a patented broad spectrum UV absorber offering excellent color protection as well as preservation of the integrity (strength) of the hair fiber itself.
According to Croda, Chromaveil is a UV absorbing quaternium compound that offers excellent UVA and UVB protection to the hair due to its superior substantivity. Broad spectrum protection is key to preserving the healthy appearance of the hair as UV radiation affects the hair in different ways. UVB rays inflict more damage to the structure of the hair fiber itself, presenting as a roughening of the cuticle, a change in texture and a loss of strength. The damage from UVA rays displays as a loss in color or a change in the color of the hair.
Extensive laboratory studies were conducted to evaluate the ability of Chromaveil to absorb radiation in both the UVA and UVB spectra. Three sets of shampoo evaluations, on both medium-brown and auburn dyed hair tresses, showed, through spectrocolorimeter readings, the tresses treated with the shampoo formulation containing Chromaveil far outperformed the control and competitor treated hair after being subjected to the equivalency of two weeks of sun exposure, according to Croda.
