A broad spectrum, liquid preservative system designed to prevent microbiological contamination in a wide range of personal care products. Applications in aqueous, anhydrous and emulsion type formulas. Stable, non-irritating, non- sensitizing at recommended levels. LPO is an optimized blend of ingredients that distribute within a formula according to their oil or water affinity to provide total antimicrobial coverage of the water phase, oil phase, oil soluble ingredients and emulsion interfaces. Globally approved for harder to preserve formulations at levels up to 1.4%. LiquaPar Optima is recommended at use levels between 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. Appropriate for preserving oil based products like salt scrubs that can have water introduced by the end user. Ingredients: Phenoxyethanol, methylparaben, isopropylparaben, isobutylparaben, butylparaben. Appearance: Clear, pale yellow liquid. Specific Gravity: 1.05 - 1.15 Assay: Phenoxyethanol 66 - 74% Methylparaben 14 - 16% Isopropylparaben 5 - 7% Isobutylparaben 3.5 - 5.5% Butylparaben 3.5 - 5.5%. Note: LiquaPar® is a registered trade mark of the manufacturer ISP / Sutton Laboratories.
