|
General Information |
PrzvFreeTM 1840 is a complete system for paraben esters-free cosmetic and personal care products. PrzvFreeTM 1840 contains no biocides or typical preservatives. Instead it uses multifunctional agents that have excellent efficacy as biostatic and fungistatic agents. It can be used as an alternative to traditional preservative blends that are seen as undesirable by the consumer. A special benefit of PrzvFreeTM is that it performs superbly at neutral pH, a state where many other alternative materials are ineffective. |
|
Compatibility |
PrzvFreeTM 1840 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. So, Ethylenediaminetetraacetic acid disodium salt (EDTA-2Na) is suggested to be added into formulas as chelating agent. |
|
Application |
PrzvFreeTM 1840 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. The application range of PH value is 2-8.The greater amount of PH value in neutral and alkaline condition, the weaker active constituent.
We do recommend avoiding lengthy exposure to elevated temperatures: for example, maximum two hours at 90°C, or maximum six hours at 60°C.
It may be not transparent at low temperature. Please heat slightly to be transparent before use. |
