Use levels .4-.8%

LiquaparPE

INCI: Phenoxyethanol, Isopropylparaben, Isobutylparaben, Butylparaben.

In complex formulas add .2% EDTA for dual preservation. Proteins, milks, and other additives would qualify for the dual preservation system.

Can be added pre of post emulsification 60-70C (140-158F)

pH restrictions – 3.7-7.5

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

Use levels: .5-1.0%

Liquid Germall Plus

Liquapar Optima

INCI: Phenoxyethanol (and) Methylparaben (and) Isopropylparaben (and) Isobutylparaben (and) Butylparaben.

In aqueous systems, a co-solvent or surfactant may be needed to help solubilize the preservative.

Can be added pre or post emulsification at or below 80°C.

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.

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

Use levels - .5-1.0%

Germaben II-E

INCI: Propylene Glycol, Diazolidinyl Urea, Methylparaben, Propylparaben.

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.

Germaben II

INCI: Propylene Glycol (and) Diazolidinyl Urea (and) Methylparaben (and) Propylparaben

Can be used with no co-preservatives and is compatible with most cosmetic ingredients.

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

Add slowly below 60F (140F) after good stirring just prior to the addition of fragrance.

pH restrictions – 3.0-7.5

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

Usage level - .5-1.0%

Suttocide A

INCI: Sodium Hydroxymethylglycinate

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

No temperature information given from the manufacturer.

Ph restrictions. Stable and active up to 3.5-12!

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

Use level .4-1.0%

Phenonip

INCI: Phenoxyethanol, Methylparaben, Ethylparaben, Butylparaben, Propylparaben, Isobutylparaben.

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.
