Vitamin E can be a confusing topic. How much should I use? Does it cause rancidity? What is the alpha tocopherol version? Read on to answer some of these questions.
Fatty acids contained in oils are known to undergo autoxidation and eventually become rancid. First these acids form free radicals, the free radicals react with oxygen and produce peroxides, and the reaction terminates in what people recognize as rancid fat.
Vitamin E is not a preservative, it is an antioxidant. Therefore it is effective in preventing the oxidation process mentioned above.
Rancidity can also be caused by using too much Vitamin E. Levels of 0.2-0.8% mixed tocopherol (50%) is a good starting point. Anything over 1% should have accelerated stability testing to verify you won’t have shelf life issues. Monitor your product at 40C and see if it gains weight. If it does, that means your product is going rancid.
Vitamin E also has significant skin benefits, and for this reason we sometimes see high levels in topical formulations. Alpha tocopherol is preferred and has been shown to maintain skin health.

This also helps suspend beads in these formulations. It will actually give you a clear suspension. Some of the characteristics are listed below:
• Easy to use liquid form
• Very compatible with surfactants
• Synergistic with salt
• Improves pearlescent appearance
• High suspending and stabilizing property
• This can be used in sulfate free formulation as well
The specialty silicone of the month is ICM 8014. This one has become our customer’s favorite to formulate with. This silicone is an ingenious creation of high molecular weight specialty silicone elastomer in a low molecular weight dimethicone fluid.
Despite the high molecular weight silicone elastomer, ICM 8014 is non-tacky, ultra-smooth with satin feel, and near perfect haze free clarity. It is being used in skin care products, color cosmetics, sun care, hair care, shower gels, and antiperspirants.
• D4 & D5 free

Each year, bee keepers harvest honey from their hives. As they clean out the hives, they inspect the “wooden ware” for any damage the hives have. Over the years the process for wooden ware repair has been to paint the boxes.
Often times now bee keepers are dipping their wooden ware in a blend of waxes (typically microcrystalline and paraffin). This process will help to seal the seams in a more natural environment and this can last up to 10 years.
We offer the full line of Strahl and Pitsch natural waxes to meet your needs! Give us a call and we’ll help meet your needs too.
