Recommended Uses

Geogard® Boost PHC delivers a broad spectrum of microbial protection with reduced levels of Phenoxyethanol for creams, lotions and moisturizers and conditioners. A single dose liquid solution which simplifies manufacturing logistics.

The product is easily formulated into lotions and conditioners and is effective at a pH range of 5-8.

Formulation Guidance

Geogard® Boost PHC should be used in the range 0.3 – 1.6%.
It is dispersible in cosmetic emulsions such as skin creams, lotions and hair conditioners.

Geogard® Boost PHC can be added at any stage of production and temperatures of up to 75°C are well-tolerated, however it is more normal to add preservatives at the end of the hot process when the temperature has reduced to around 40°C.

Stirring is required to ensure uniform dispersal of the preservative ingredients.

Technical Details & Test Data

Microbial Protection Performance

Method overview

The Lonza Preservation Efficacy Test method was performed to evaluate antimicrobial performance. The study was performed over 28 days, with sampling performed every 7 days and an additional bacterial sampling point at 2 days.

  • Formulations were inoculated with single cultures containing either a bacterial load of 1.0x106 to 1.0x107 CFU/g or a yeast and fungi microbial load of 1.0x105 to 1.0x106 CFU/g.
  • Challenge microorganisms are depicted in table below.
  • Formulations were sampled at each time interval and recovered using the quantitative pour plate technique.
  • The microbial recoveries of each sample were calculated. Counting limits of >330 CFU/g and <10 CFU/g were employed.
    (Minimum reportable value <100 CFU/g)
