Abstract:
A hair and scalp protective formulation containing a peroxidase enzyme with standardized peroxidase activity and a synergistic compound which enhances the peroxide-reducing activity of the enzyme by inhibiting the deleterious effects of any organic compounds, or heavy metals that would normally inhibit the enzyme, consisting essentially of a water dispersible formulation, consisting essentially of:(a) a yeast extract adapted to enhance the peroxidase activity of the peroxidase, such yeast extract being known as live yeast cell extract;(b) a chemically-inert carrier material for the enzyme selected from the group consisting of polyvinylpyrrolidone, aqueous medium-dispersible cross-linked polysaccharides, guar gums, xanthine gums, alginic acid, chitin, acrylate, imidozolidnyl ureas, phenoxyethanols, and chloroxylenols;(c) a germicide/preservative agent selected from the group consisting of 2-bromo-2-nitropropane-1,3-diol, quanternium-15, benzoisothiazide, and parabens esters; and,(d) a metal chelating agent selected from the group consisting of phytic acid, sodium phytate, and a hydroxylated benzoic acid.
