LiquaPar
Oil is a 100% active, clear, stable, liquid blend of Isopropyl,
Isobutyl, and n-Butyl esters of Parahydroxybenzoic Acid. This unique
combination of parabens is a very effective preservative against
Gram-positive bacteria, yeast, and mold. The higher alkyl esters
present in LiquaPar Oil are not only more active but also more stable
and resistant to hydrolysis than traditional lower alkyl powder
parabens. It does not contain halo-organic components, formaldehyde, or
formaldehyde releasers. LiquaPar Oil minimizes problems of grittiness
or crystallization often associated with the use of individual powder
parabens and it can be readily incorporated into many types of cosmetic
formulations without heating.
LiquaPar Oil is approved for use worldwide. It is approved for
use in the Americas and permanently listed up to 0.8% without
restriction in the European Union. In Japan, LiquaPar Oil is permitted
up to a maximum total paraben concentration of 1.0%. |
|
| Applications |
 |
Useful in a wide range of cosmetic formulations including anhydrous systems. |
|
Recommended use level of 0.4-0.8%. |
|
For best results, LiquaPar Oil can be added pre- or post-emulsification, in systems with a pH range of 3.0-7.5. |
|
Studies
indicate that many fragrances are miscible in LiquaPar Oil thereby
facilitating their incorporation into finished products. |
|
|
| 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. |
