I have several surfactant >samples from Ajinimoto that I'd like to try. I guess a lot would depend how you define " a mild surfactant " . Ajinomoto has several different mild surfactants. You should ask them about leaving their surfactants on the skin. Ajinomoto should be the experts for their product. I think Ajinomoto makes many neat, innovative surfactants but I find that Ajinomoto surfactants are too expensive for my formulations. Most Ajinomoto surfactants are single sourced. Have you considered using a simple, inexpensive, multiple sourced nonionic emulsifier? >For preservative issues, I have LiquiPar Optima and Liquid Germall >Plus. Would either of these be suitable? I think that either LiquaPar Optima or Liquid Germall Plus would be excellent choices. The only way to tell if LiquaPar Optima or Liquid Germall Plus are effective is with a challenge test. I would also use Tetrasodium EDTA or Disodium EDTA. And I would also develop a method of processing that would discourage microbial contamination. Use heat wherever possible. >My hydrosols have citric acid and sodium benzoate added. Will these >be suitable, or should I stick with distilled water?

Your " light bulb " moment created the idea. An idea has no dimension. Ideas are not red or blue. Ideas have no weight nor do they occupy space. As the creator, you will give your idea dimension. You will provide the shape and form. I would keep an eye on your costs. Raw material costs have killed many new products. Maurice -------------------------------------------------------- Maurice O.

Guest guest Posted September 13, 2003 Report Share Posted September 13, 2003 Thanks for the info, Maurice. > You should ask them about leaving their surfactants on the skin. Yes, that's exactly what I thought about 5 minutes after sending my email to the list. > I find that Ajinomoto surfactants are too expensive for my formulations. I only have their samples. I didn't get a price list from them yet. It would just be so typical for me to find a material I really like, then find out it's cost prohibitive. I'll send an email to the sales rep to get prices for the samples I have. He's been extremely helpful so far. > Have you considered using a simple, inexpensive, multiple sourced > nonionic emulsifier? That had crossed my mind - however, I contacted another company, Croda, to get a few samples, and have never heard back from them. I told the lady that I was talking to what samples I wanted and what I wanted to use them for. She said she would give the information to their chemists and they would contact me directly to give me more information/guidance. But no call came. > effective is with a challenge test. yes, that will be the next step. Just want to find a lab that's fairly local. > I would also use Tetrasodium EDTA or Disodium EDTA. Hmm, hadn't thought about those. I'll have to order some as I don't have any. I'll play with what I have until I can get some. > Use heat wherever possible. Indeed. I've been reading this list for over a year now (perhaps close to 2?), and I've learned so much. And this is one of the things that I actually remember without having to look in my notes - apply heat whenever possible. > but I would stick with distilled/deionized water. I think I will stick with distilled water, with some aloe vera (I was thinking about 25% of the water phase, but I may reduce that). > Raw material costs have killed many new products. A very good point, Maurice. Thank you for your help. I hope to start playing with this today while my husband is at the theatre watching a shark documentary with the kids.
