Function
1. Caprylhydroxamic acid could be used as a replacement for traditional preservative in cosmetics, still has a highly effective anti-bacterial capability in neutral environment. However when under the same circumstances, the others will be weakened.
2.Caprylhydroxamic Acid can chelate with Fe2+ and Fe3+ excellently. Then, it can stop mold to get Fe.Caprylhydroxamic Acid has the best length(C8) of C chain to promote degradation of cell membrane structures.
3.It can take place of traditional preservatives when applied to the cosmetic.it is still effective when pH is neutral;
4.Caprylhydroxamic Acid is compatible with most cosmetic ingredient.
5.Caprylhydroxamic Acid may be used in emulsion,anhydrous and surfactant systems.these include creams,lotions,shower gels and make-up.
