Caprylhydroxamic acid could be used as a replacement for traditional preservative in cosmetics. It still has a highly effective anti-bacterial capability in neutral environment. However when under the same circumstances, the others will be weakened.

Application: Caprylhydroxamic acid may be used in emulsion. Anhydrous and surfactant systems. These include creams, lotions, shower gels and make-up. It may be added to the water phase, at ambient or hot temperatures, or may be added post-emulsidication of O/W emulsions. We do recommend avoiding lengthy exposure to elevated temperatures: for example, maximum two hours at 90C, or maximum six hours at 60C.
