Octanohydroxamic acid is for preservative-free cosmetic and personal care products. It is not typical preservative, but has excellent efficacy as biostatic and fungistatic agents.
Octanohydroxamic acid is ideal for personal care products where a paraben-free or preservative-free claim is needed. It can be used as an alternative to traditional preservative blends that are seen as undesirable by the consumer. A special benefit of octanohydroxamic acid is that it performs superbly at neutral pH, a state where many other fungistatic materials are ineffective.
Octanohydroxamic acid is compatible with most cosmetic ingredients. However, it can interact with residual iron found in some clay-type compounds (e.g., bentonite, silicates, etc). This interaction with iron may produce a very mild orange color or color shift that is barely perceivable to the eye in most formulations. In cases where the clays are high in iron, the colored compounds may be more perceivable. |

| Application |
Octanohydroxamic 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-emulsification of O/W emulsions.
We do recommend avoiding lengthy exposure to elevated temperatures: for example, maximum two hours at 90°C, or maximum six hours at 60°C. |
