Hevey > Convergent Cosmetics, Inc. > http://www.ConvergentCosmetics.com > ------------------------------------------------------- I have a similar problem with my customer base not wanting to see those ingeredients. Can you tell me what percentages you used? i realise each formula is different and requires testing to guarantee the preservatives efficacy, but if you could just give me an average % for a cream or lotion containing basic oils, butters, and water?

PS: Proper processing/ is very important. You have to start with a clean product if you want to give your preservative system a chance. Preservative systems are suppose to prevent the growth of microorganisms. Quoting from Principles of Preservation: http://health.groups.yahoo.com/group/Cosmeticinfo/files/Preservative_Info/Princi\ ples_of_Preservation.pdf " A preservative is defined as a material that will prevent the growth of or react with and destroy microorganisms that might damage the product or create a health hazard by growing on or in the product. An antiseptic is a material that prevents the growth of and/or destroys microorganisms when applied to living tissue. An example of an antiseptic would be hydrogen peroxide. Disinfectants are materials that destroy disease-producing microorganisms on inanimate objects. Germicide is a general term used to refer to products that kill microorganisms. Two common suffixes used in microbiology are the terms cidal meaning kill and the term stasis meaning inhibition of growth.
