    Microbiological Test Kit

     

    Double sided test kit for DIY testing of total aerobic bacteria, yeasts and moulds

     

    Description:  The microbial test kit is a tube which includes a slide coated with a sterile nutrient surface to allow biobogical testing of your product [like cream, lotion, gel, shampoos] etc. for bacterial and mould growth.  This microbial test kit allows  quick and easy quality control of your finished products.  Our Microbiological Test Kits are manufactured under aseptic conditions and the agar surfaces contain no toxic ingredients that could be transferred to the products being tested. Each dip slide is supplied within a transparent, shatterproof protective tube. Subsequent contamination is therefore prevented, and the results can be evaluated with the tube sealed, thus avoiding any risk of contamination to the end-user.

    The agar coated dip-slide enables simple sampling and quick evaluation of the results; testing can be done by anyone; you don't need any microbiological training or special laboratory equipment.

    The slide can be used for testing

    surfacesurfaces, 

    MTK3semi-solid materials and

    MTK1liquids that contain water.

    (Water is usually the source for bacteria, yeast and mold growth).

     

    The kit contains 2 different agar-type surfaces;  one for testing of total aerobic bacteria count the other; a malt based agar, used for yeasts and moulds.    Every test Kit sent out will be accompanied by a comprehensive brochure with full instructions and illustrations to help you determine the total bacterial or yeast/mould counts. Typical cfu (colony forming unit) counts are:

    MircoTest-Kit-Bacteria

        Bacteria colonies: 100, 1000, 10'000, 100'000, 1 million, and 10 millions

     

     DUE TO THE NATURE OF THIS PRODUCT, ALL SALES ARE FINAL, IT MAY NOT BE RETURNED.

     Whilst there are currently no legal requirement to ongoingly challenge test cosmetic products in Australia, you may want to prove that your own preservative scheme is working,  or simply raise the standards of your production methods. Should you require a more comprehensive challenge testing service for your products, then we suggest that you contact your local Microbiological Consultant Services.

     

     

  • Sorbitol (70%)

     Sorbitol 70%

    Sorbitol is  often used instead of glycerine as it similarly retains moisture and provides that velvety feel to the skin. Sorbitol besides being more resistant to bacteriological degradation is also less vulnerable to mould growth than many other humectants in cosmetic formulations.

    Chemically sorbitol is a water soluble polyhydric alcohol with a sweet taste. It offers high formulating stability in addition to its humectant properties. It is used in the manufacture of pharmaceutical products such as toothpaste, foods such as sweets and chewing gum.

     Sorbitol is typically produced by the hydrogenation of dextrose. The dextrose is derived from starch via an enzymatic process. The resultant clear dextrose solution is then reacted with hydrogen gas in the presence of catalyst in the reactor. The resultant sorbitol is subsequently subjected to a number of purification processes such as carbon treatment ion exchange etc. The final concentration of Sorbitol (70%) is achieved in evaporators.

    Note: this product has a density of 1.29 g/mL thus 1kg is less than a litre! 

    Whilst the products are of the higest standards and we maintain all care and repack under GMP we do not certify that the products are of food grade

       
  • Stabil [ Phenethyl Alcohol and Caprylyl Glycol]

    Stabil [ Phenethyl Alcohol and Caprylyl Glycol]

    Stabil is an unique alternative to the traditional cosmetic preservatives as it is paraben and formaldehyde free.

    Stabil allows for the creation of self-preserving formulations with its non sensitizing / nontoxic broad spectrum antimicrobial activity.  The product has a very reduced irritation potential compared to some systems and is there to provide a paraben and formaldehyde-free system. This combination of Phenethyl Alcohol and Caprylyl Glycol imparts cosmetic benefits such as skin emolliency, improved skin feel, and a mild fragrance.

    As a clear, colorless liquid with a mild rose-like odour, Stabil is an optimized combination of widely accepted and safe cosmetic ingredients which

    • is globally approved
    • does not contain any preservative listed in the EU Annex VI or allergens.
    • exhibits broad spectrum antimicrobial activity. 
    • allows the claim 'preservative-free' for formulated products.
