Recommended Usage Guidelines
One very frequent question among crafters is how much of a given ingredient to use. Here are some guidelines I like to follow. All measurements are by weight:
Antioxidants:Rosemary Oleoresin Extract (ROE): 0.5% Vitamin E (including low alpha tocopherols): 2% Approved for cosmetics; don’t use ROE in lip products due to danger of ingestion.
Botanical additives (including clays, seeds, scrubs and plant parts): Amount as desired. Approved for cosmetics; don’t use in lip products due to danger of ingestion.
Cosmetic colors: As desired, but bubbles should always be white, and lotion should be white when rubbed into skin without leaving coloring behind.
Cosmetic waxes –Emulsifying wax –up to 15%. Stearic acid up to 3%. Beeswax and candelilla wax –as desired, depending on product being manufactured.
Fixed oils and butters –Add as desired to CP soap (include in SAP calculations) and MP soap (up to 3-5%. If your finished soap is soft to the touch or excessively slippery, you’ve added too much.
Flavor oils/sweeteners: 1% in leave-on lip products such as balms and glosses. If it tastes bitter, you have used too much
Fragrance oil: 2-3% in both melt and pour and cold process soaps. 1% in liquid soaps.
7% in bath oils
1% in massage oils, lotions and other “leave on” skincare products
Moisturizing additives: Aloe Vera: 1%. All others up to 3-4%. Approved for cosmetics; don’t use in lip products due to risk of ingestion
