    pH restrictions – 3.0-7.5

    Usage levels - between 0.5% - 1.0%. 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.

    Germaben II-E can be used in problem formulations without the need for additional co-preservatives. It is compatible with almost all cosmetic ingredients, including surfactants and proteins.

    Use Germaben II E when making emulsions that have 25% oil or more.

    Add slowly after emulsification and prior to addition of fragrance. Or add to fragrance and add mixture slowly to finished formulation after tempertature has dropped below 60C (140F).

    pH restrictions 3.0-7.5

    Use Level .5- 1%

    Is a complete preservative in that it covers microbial, fungus, and yeast.

    Suttocide A, when used in conjunction with LiquaPar Oil, is particularly effective in complex formulations.

    Deactivated by some PEG compounds.

    Water should be heated to 140 - 158 degrees F to properly dissolve the preservative. Phenonip can be used at higher heat levels without losing effectiveness and with higher oil concentrations than most other preservatives. To ensure a complete preservation, add ½ of the preservative to the water portion and the other ½ to the oils portion before emulsifying.

    pH restrictions – 3-8

    Is a complete preservative in that it covers microbial, fungus, and yeast.

    Recommended Use Level - .5-1.0%

    The Breakdown

    If your formula contains water, you can use:

    Germaben II - less than 25% oil

    Germaben II-E - more than 25% oil

    Germall Plus

    Liquid Germall Plus

    Phenonip

    Liquapar PE

    Liquapar Optima

    Optiphen

    Optiphen Plus

    If your formula contains only oils, butters and waxes and does not contain water but there is a possibility that the consumer could introduce water into the product, you can use:

    Phenonip

    Liquapar PE

    Liquapar Optima

    Liquapar Oil

    Optiphen

    Optiphen Plus

    If your formula contains only oils, butters and waxes and does not contain water, you do not need a preservative, but I would highly recommend one. If the end user stores the product in the bath room or any humid environment, humidity can get in the product and cause bacterial, fungus, or yeast growth.

    General Info

    For cold mixing, add preservative early in the process to ensure adequate mixing.

    Get a ph meter from www.lotioncrafter.com or ph strips from www.thesage.com or a local pool supply!

    Use proper sanitization methods. Does you no good to waste money on preservatives if you are unclean in your storage, mixing, and bottling procedures.
