LiquaPar
Optima, a liquid preservative system, is an optimized blend of
Phenoxyethanol, Methylparaben, Isopropylparaben, Isobutylparaben, and
Butylparaben. This unique blend of parabens is primarily antifungal,
and when combined with Phenoxyethanol, the complete system has broad
spectrum antimicrobial activity. These components partition within a
formula according to their water or oil affinity to provide total
antimicrobial coverage of the water phase, oil phase, oil soluble
components, and emulsion interfaces. LiquaPar Optima is effective
against Gram-positive and Gram-negative bacteria, yeast, and mold. It
does not contain halo-organic components, formaldehyde, or formaldehyde
releasers.
LiquaPar Optima is approved for use worldwide. |
|
| Applications |
 |
For use in a broad range of applications; especially effective in emulsions. |
|
Soluble
in commonly used solvents and can be easily incorporated into most
formulations; in aqueous systems, a co-solvent or surfactant may be
needed to help solubilize the preservative. |
|
Can be used to preserve a wide range of leave-on and rinse-off products. |
|
Can be used in a pH range of 3.0-7.5. |
|
Recommended for use in personal care products at levels between 0.5-1.0%. |
|
Higher
levels of LiquaPar Optima may be required in formulations with higher
levels of non-ionics and proteins since these compounds are known to
interfere with parabens. |
|
Although
Phenoxyethanol is slightly volatile, LiquaPar Optima is stable at
temperatures up to 85°C, but it is always best to add preservatives at
the coolest possible temperature. |
|
For cold mixed systems, add LiquaPar Optima early in the process to allow for adequate mixing. |
|
|
| Every
cosmetic formulation requires a specific preservative system to meet
its individual needs. Therefore, every newly developed or modified
product should be challenge tested to assure
preservative efficacy. |
