"Is this the right preservative for me to use for my rose water toner? "

Click Here To View 1 answer(s)

Email Me When This Question Gets Answered

Staff Answer This preservative is for products containing over 25% oils and butters. Toners are mostly water so this probably is not the correct preservative to use. You may want to look at the ones that are water-soluble and check the ingredients for each. Some contain parabens which some people prefer to stay away from.

"I bought Germaben IIE per Anne Watson's instructions, to make a lotion that includes goat milk. Can I also use this product in other lotions that don't have the high oil content, or do I need to buy an additional preservative for lower-oil products? Meaning, is Germaben IIE merely overkill on a lower-oil product, or will it actually be ineffective in such a product?"

Click Here To View 1 answer(s)

Email Me When This Question Gets Answered

Staff Answer It is best to use preservatives appropriate for the product. Germaben II, as you know, is for products with at least 25% oils. This also works great in scrubs. It is fine to use in a lotion without milk products or high oil content but it is always important to test any product/preservative for compatibility.

Click Here To View 1 answer(s)

Email Me When This Question Gets Answered

Staff Answer Since your product contains no water and is not a product that will be used in the bath or shower, you do not need a preservative. You should use an anti-oxidant such as Vitamin E or ROE (Rosemary Oleoresin) to help keep the oils and butters from going rancid. The Aloe Vera Gel does contain water but has its own preservative added.

Staff Answer This preservative is for products using more than 25% oils. We are assuming your body spray is water based and would work well with Preservative-Water Soluble PF. The directions state this should be used at 0.1-0.5%. This can also be used for the face mask.

Staff Answer We would recommend using Preservative-Water Soluble PF. The Preservative-Water Soluble/O25 is for products containing over 25% fixed oils/butters. You would need to decide which one works best for your product according to the actual recipe.

Staff Answer Preservatives are necessary when incorporating water into a product. I do not believe that adding a preservative will help combat mold or fungus if you intend to use fresh or dried fruit. It would be best to use a fruit scented fragrance oil and botanicals such as orange peel pieces to enhance your product.

"I'm confused...it says to use this product as a preservative in any products containing more than 25% butters/oils, but reading some of the other Q&As, it seems to only be necessary when water is also added to a product. Say I'm making a body cream, primarily consisting of butters and oils, and no actual H2O is added, would I still need to use this preservative?"

Staff Answer Germabem II E can be added to a lotion that has more than 25% oils and butter. This will prevent the lotion from spoiling too fast. If your recipe does not contain any water or water based additives and your customers will not be introducing water through use then you do not need a preservative at all. Preservatives such as Germaben II E will not prevent oils and butters from going rancid. You can add an antioxidant such as Vitamin E or Rosemary Oleoresin Extract to extend the shelf life of oils

Staff Answer This preservative is recommended for formulas that contain more than 25% oil. Whether this preservative will work will depend on if any other ingredients will be in your formula. This product has not been tested in a recipe of only honey and ground oats and, unfortunately, we cannot be sure how it will react if added.

Hello, Yes you would calculate the ewax and stearic acid into your total batch weight. Fixed oils are your base oils that you use in your recipe( also known as carrier oils too). Thank you for your question Erin

Hi, yes the ewax and stearic acid amounts should included when calculating the percentage of the oils portion in your lotion recipe. Fixed oils refer to the oils and butters such as soybean oil or shea butter.

Staff Answer Germaben II E is a preservative and preservatives only help inhibit the growth of mold and bacteria when water is introduced to a product. To extend the shelf-life of an oil, you would need an antioxidant like Vitamin E or Rosemary Oleoresin Extract.
