ANTIMICROBIAL ACTIVITY

MIC [Minimum Inhibitory Concentration]
The preliminary evaluation on Plantaserv Q has been performed by MIC test [Minimum Inhibitory Concentration]. MIC is a turbidimetric evaluation that designed to determine the needed concentration of a preservative to inhibit the microbial growth. This test is extremely important in order to define the efficacy of the preservative and the sensitivity of different microorganisms to a given preservative.
The following are the technical information on the MIC evaluations on Plantaserv Q.

Preservative Efficacy
The antimicrobial activity of Plantaserv Q has been tested in detail by a simulated microbial attack, better known as a \'Challenge Test\'.
The Challenge Test allows the evaluation of the real capacity of not only preventing microbial contamination, but reducing it to where it becomes safe for human health, once contamination has occurred.
The following are the technical information on the Challenge Test on Plantaserv Q.

To determine the microbial survival after 7, 14 and 28 days a total viable count is performed and the results graded as:
Adequate :  Microbial survival < 0.2%
Debatable :  Microbial survival < 1% [ie between 0.2% & 1%]
Insufficient :  Microbial survival < 10% [ie between 1% & 10%]
Inadequate :  Microbial survival > 10%

When used as recommended and correctly blended in skincare products Plantaserv Q adequately preserved all products tested, including shampoos, skin tonics, cleansers, conditioners, body milks, emollient masks, moisturisers, gels, creams, scrubs, serums, etc.
