Liquapar Optima is a broad spectrum, liquid antimicrobial that can be used in a wide range of personal care products. It is recommended for anhydrous and emulsion type formulas. It is stable, non-irritating, non- sensitizing at recommended levels.
Recommended Usage: 0.5% - 1.0%.
Can be added pre or post emulsification at or below 80°C. If pH of the water is above pH 8 before neutralization, LPO must be added post emulsification. In alkaline conditions ionization and/or hydrolysis can occur.
For non emulsified products, LPO may be incorporated directly into the formula during manufacturing. Can be added to cold systems or at elevated temperatures at a pH range of 3 - 8. May be required in higher levels in formulas with high levels of non-ionics and proteins as these compounds are known to interfere with parabens.
Can be combined with Liquid Germall® Plus or other Germall® brand preservatives in very difficult to preserve formulations like silicone in water emulsions. Every new or modified formula should be challenge tested to ensure adequate preservation. LiquaPar Optima is similar in some ways to the widely known Phenonip product. Appropriate for preserving oil based products like salt scrubs that can have water introduced by the end user.
