It is only partially soluble in water-based products whilst more soluble in oil based products. It is best used in creams, lotions and serums.
It is fully effective in anionic, nonionic and cationic formulations. It is effective on gram negative and gram positive bacteria, yeasts, and mould fungi.

Store in a cool dry place out of direct sunlight.
HOW TO USE IT
Use in formulations at 0.5% to 1%. In our formulations, we always use 1% unless part of the formulation includes herbal materials such as a tea infusion or decoction, then we use 1.1% which is also the maximum recommendation. Higher amounts than this have the potential to cause skin irritation.
It is not fully oil or water soluble so is best used with creams and lotions. When used in a water based product like a toner, it is more soluble if added to glycerin or sorbitol before being added to the toner. It can also be solubilised with Emulsifan.

It is stable at variable temperatures. We recommend adding it in Stage 3 in creams and lotions, or when the product temperature is under 40°C.
The ethyhexylglycerin content can destabilise weak emulsions. To avoid this, make sure your cream and lotions emulsions are stable before the preservative is added.
As it is colourless, it will not change the colour or affect the clarity of gels. It also has a very mild smell compared to some other preservartives, making it the preferred choice for unscented products.
The best method for measuring the preservatives (and all other raw materials) when adding to your products is to weigh them on an accurate scale that weighs down to 0.1 grams. You will find older formulations that use drops, but this is no longer accurate enough.
Skin Care
Use in treatment gels such as Aloe Vera or Hyaluronic Acid serums as well as all types of creams and lotions.
It can tolerate high salt content so is suitable for use in salt body scrubs. Body scrubs may be anhydrous and not be thought to need a preservative, but when they are used with wet hands in the bathroom environment, they should be preserved and Preservative 12 is an excellent choice for this.

Hair Care
Do not use with shampoos and body washes as it will not work. It works well with non-ionic, anionic and cationic materials that are used in hair care products like conditioners.
Hair care products often use a lot of herbs which are more prone to microbial contamination, so remember to increase the percentage of Preservative 12 if using infusions and decoctions to 1.1%.
CAUTIONS / CONTRAINDICATIONS
Do not blend different preservatives with each other unless you are experienced in this area and can have the result tested for efficacy. If you are adding extra materials to a base product, you may need to add extra preservative as well. Ensure the same preservative as the base product is used.
We do not recommend this preservative for use with clays. We found in our tests, that the clay absorbed the preservative leaving the water element vulnerable to contamination.
NOTE: PRESERVATIVES & ANTIOXIDANTS
Preservatives are needed for most cosmetic formulations that include water. There are some companies that have very stringent manufacturing procedures to ensure the hygiene of the product and the ratio of some of the materials may make the product quite stable against contamination. Shampoos can sometimes do this as they are often very alkaline, However, that alkalinity is not very comfortable on the scalp.
Vitamin E used to be referred to as a preservative because it preserved the shelf life of the product. However, Vitamin E only acts as an antioxidant for the oils in the product, preventing them from going rancid too quickly. It is not a preservative by today's accepted standards.
