Guest guest Posted March 14, 2000 Report Share Posted March 14, 2000 I know that preservatives cause a lot of discussion on these lists. I've given up looking for the perfect " natural " one that will extend shelf live of products for at least a year. I saw a product yesterday offered by someone doing a co-op on a preservative called Uniphen. The price seems reasonable ($12.00) for a pound. She has used ..025 oz in 20 oz of oils and water with no spoilage for many months now. I will be buying 2 pounds of this, and listing it on my ingredient label for those who may be sensitive. I feel that most people don't seem to care about the Preservative that are in thier food they eat, so why should this be an issue for the Joe average consumer in his/her cosmetics??? Just thought I would check to see if anyone else has used this product in lotions or even soap? Thank you, __________________________________________________ Quote Link to comment Share on other sites More sharing options...

She has used >.025 oz in 20 oz of oils and water with no spoilage Hi, It is Uniphen P-23 and is a blend by Induchem. Label should read like this: Phenoxyethanol (and) Methylparaben (and) Ethylparaben (and) Propylparaben (and) Butylparaben. You only need to preserve the water weight. Most preservatives when bought in bulk are in the same price range. HTH, Jen Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 15, 2000 Report Share Posted March 15, 2000 Perhaps most people don't care, but I do. I agree that a preservative like BHT and BHA concern me less when it involves my skin, but I avoid all foods that contain them, and I only eat food that has BHT in the packaging occasionally. There is so much junk in our food that we cannot control, that if I know about it, I will avoid BHT. On the other hand, I don't manufacturer hundreds of pounds of soap, and haven't lost lots of soap to rancidity. So, I think it all depends on your perspective. I am looking for an alternative (a more natural preservative), but then other people have told me that soap cannot turn rancid, it is only the oils that turn rancid prior to making the soap. If your customers don't mind the preservatives, then why not use them? Or perhaps you could have two lines, one with and one without, or even another with more natural preservatives. I too continue to be interested in the preservative issue, because if I make a product now, I may want to give it as a gift at Christmas, and I don't want it to go bad.

This is what I've read. " Used to extend the shelf life of products. Highly toxic, however, still widely used. These ingredients are known to cause allergic reactions and skin rashes.

I am not sure about most of them but this one Uniphen if purchased in 20kg bulk sells for around $12.00 per kilo which is just a little over 2lbs. Making the it around $6.00 per lb.

Guest guest Posted July 6, 2000 Report Share Posted July 6, 2000 >This preservative is a patented combination of olidinyl Urea, the most >active member of the Imidazolidinyl Urea family of preservatives >Anyone heard anything good or bad on it? It's Germall Plus that is made by ISP/Sutton. You can read all the technical data on it on the manufacturer's site. It's made by the same folks that brought us Germaben II and others. Compared to Germaben II, it doesn't have any parabens, it's much more cost effective to use, and it's effective at a lower concentration. I did some research on Medline and other databases on IPBC and the only negative thing I could find was that in one test it was shown to be a skin irritant. However, that test was done with a 1% concentration of IPBC, Germall contains less than 2% and when you do the math, even using Germall at the highest use rate you'd still only have something like 0.00007% IPBC in your product. From all the data I read on this product it seems to be a very good and effective broad spectrum preservative. I've now switched to using it. Warmly, Sherri Oshun Spirit Arts Ltd.

I was exactly where you are not very long ago! You have a fantastic attitude of being open to learning as much as possible--forgive me! There is alot of misinformation around and also controversy, especially with this whole preservative thing and some people refuse to see the obvious gimmicks, etc. I am so glad you are open to learning. I wish the GSE was as harmless AND effective as " they " claim. Research just proves otherwise. Many authors that I admire, the Cavitch book on soapmaking, the Dina Falconi book on making natural cosmetics, and others do recommend GSE. Several reputable suppliers--and one that I buy from and like--will tell you that GSE is an effective preservative. Some other suppliers will tell you that is an endocrine disruptor and is actually dangerous to use! I was very interested in using potassium sorbate/sodium benzoate as a preservative in lotion. There is a website supplier of bulk bath and body products and ingredients for people to purchase that recommend using potassium sorbate, so I decided to investigate what research has to say about that as a preservative for cosmetics. Actually, there seems to be some evidence that is somewhat effective in certain low pH situations in applications other than cosmetic, but not enough that I would feel comfortable selling a lotion with that as the only preservative. I decided to look at whatever research is available and make my own decisions on what science has to say....I did alot of Medline searches on various preservatives, chemicals, etc. and came to the conclusion that there unfortunately NO truly effective natural preservatives for bath and body products that I would feel safe using in products that I give away or sell. I will make something for myself and perhaps not use a preservative if it will be used quickly. Otherwise, I use a commonly recognized preservative that has undergone alot of testing in different situations for safety and effectiveness. There are several to choose from, but I personally like using either the germall plus powder or the germall plus liquid. I will let you know who you can purchase these from if you are interested. Also, one more thought. I highly, highly recommend an accurate scale. Mine measures to .1 for accuracy. It is wonderful and is absolutely necessary since all formulations are done by weight. I am rambling and telling more than you asked for. but I Know how it is when you are first starting out. If you need any info and i can help, let me know.

Guest guest Posted October 31, 2000 Report Share Posted October 31, 2000 Pat, thankyou so much for the information, Angie you too. I have a dilemna going on so maybe you and the others who are far more expert that I am can help. My target market is a group of people like myself who all have the same illness, Fibromyalgia, and who are all on the same medical protocol. Due to this proctocol we must not apply anything to our skin, even the lightest touch, that will contain any form of salicylate. We are trying to find the COMPLETE chemical breakdown for fixed and essential oils and just have been at a dead end. Now lately there is some word that possibly the parabens may contain salicylates! So our search for a skin care and bath product, not to mention makeup, is a lengthy and frustrating one. I want the products I make for my friend to be safe in all ways, so they have to have SOME form of safe preservative but it also must be free of any form of salicylates. Even soap isn't safe many times! So far we are limited to using cocoa butter, soy oil, corn oil, rice bran oil, shea butter, and emu oil or any animal fat for our products. Do you, or does anyone of the wonderful people here, know where I can find the chemical composition of fixed and essential oils and preservatives? I've already tried places like Liberty Oils, Aubrey Organics, and a few professors of chemistry. One other question. Would the addition of some form of alchohol work to preserve a cream or lotion that contains an aquaeous solution? What if it was an all oil/wax solution? Thanks so much.

If there is anything you know of that I can make for her it would mean the world to me. I have been making a goat's milk soap/castille bar for her that seems to be okay. I use absolutely no EO's. Just olive oil, beeswax, lye, goat's milk and water. I would be happy to share it with you if you think it may help.

A good preservative typically has individual components that specifically control both. I think you are referring to Germaben II, which is a good preservative. A couple of other good preservatives are Phenonip and Germall Plus. There are advantages and disadvantages to all of them, but they all are recommended for water soluble formulations. I prefer Germall Plus Liquid for various reasons. Polysorbate 20 is not a preservative....it is a nonionic surfactant that is usually used to solubilize oils and water into solution. You may be thinking of Potassium Sorbate. It is used in the food industry to help preserve certain products. It is not usually a good preservative on its own and requires a very acidic environment (low pH) to be effective---anything higher than 5 or so doesn't work. Most formulations are a higher pH than that so that alone makes it a poor choice. I tried it myself when I first started out. The smell alone is enough to make it undesirable, but it is also an irritant to skin. As far as trying to use eos to preserve your creams and lotions, etc. Been there, done that It does sound reasonable doesn't it? There are studies out there that have demonstrated thyme oil and others have killed bacteria in certain conditions........problem is that even though some eos do have excellent antiviral, antibacterial, and antifungal qualities, they are short-term and will not be very effective in inhibiting mold and bacteria long-term in a cream or lotion. Plus the levels that you would have to use them would likely be toxic or problematic at the least. So, to me our best bet is to use the synthetics and use them properly. Which one you choose is really up to you. Hope this has helped a bit. Most of all have FUN everything!

Guest guest Posted June 12, 2003 Report Share Posted June 12, 2003 I got free samples of preservatives from ISP which is Sutton Laboratories. They are like 4 oz bottles so it’s enough to experiment with. Got a variety. www.the-buying-group.com <http://www.the-buying-group.com/> also carries preservatives at good prices.
