General description

Preservative blend consisting of Methyl Parahydroxy-benzoate, Propyl Parahydroxybenzoate and Benzyl Alcohol.

Nipaguard MPA is a broad spectrum antimicrobial agent comprising a synergistic blend of esters of para-hydroxybenzoic acid (parabens) in benzyl alcohol designed for preservation of a wide range of cosmetics and toiletries.

Applications

Typical use concentrations of Nipaguard MPA are 0.3 -0.8 %. Nipaguard MPA provides activity against gram positive and gram negative bacteria, yeasts and molds.
It retains activity in the presence of most cosmetic ingredients. In the presence of proteins and nonionic surfactants slightly increased use concentrations of 0.4 - 1.0 % might be necessary.
Nipaguard MPA is stable to heat and UV light and active within pH range of 4.5 -8.
It is non-irritating to skin, eyes or mucous membranes at normal use concentrations.
Nipaguard MPA is up to 0.5 % soluble in water, readily soluble in oil phase ingredients and in many organic solvents.

pH stability
Nipaguard MPA remains fully stable over a wide pH range from 4.5- 8.

Temperature stability
Nipaguard MPA should be incorporated during the cooling stage of hot processes to avoid loss of benzyl alcohol. The recommended maximum handling tem-perature is 40°C.

Low Toxicity
LD50 oral (rat) - >8000 mg/kg for the active ingredients i.e. practically non-harmful by ingestion.
