Yes, cosmetic. They want a “prevents frostbite” claim.

Exact examples would be helpful - but I’ll research the terms you mention also.

I think I saw that one demoed once - good find!

There are a few ways that you can do this on a low budget.
For higher viscosity products, you can fill the product into caulk dispensing tubes, and then use a powered caulk gun to fill your containers. There are even more automated systems that do this - they are primarily designed for filling epoxy.For average lotions and creams, you can use one of these manual, gravity-fed machines: http://cosmeticsmachinery.blogspot.com/2013/10/hand-manual-liquid-filler-equipment.html Or,Going with a little more automation is something like this:Or this:Or this:(We have one of these here at Beaumont - it’s very reliable, but it wasn’t inexpensive)Something like this is probably over-kill:http://www.ebay.com/itm/28-Valve-Bottle-Filler-Federal-Cemac-Stainless-Filling-Machine-/381112006940 -
@MarkBroussard, unfortunately, that thinking has gotten a lot of chemists and companies in a fair amount of hot water, legally speaking.
The door to this is opened by what is called the “Doctrine of Equivalents”, in US patent law.Anyone not a lawyer can see how confusing this is. That’s why we always suggest consulting a lawyer when you run into a patent problem.But…it’s the second part of this issue that’s the real concern. Whether or not you are actually infringing on a patent (and only a judge can determine this), a big company can easily cost you many thousands of dollars in legal bills, at a minimal cost to themselves. That, plus the accompanying hit to the company’s reputation, (no one really wants to be seen as stealing ideas) is what deters most companies from attempting anything questionable. -
@nasrins (and everyone else) - I know I have a tendency to use complicated/technical English. If anyone doesn’t understand, please ask me and I will explain in simpler terms.

You can do a knockout experiment for skin reactions, too.

Almost everything that does this is synthetic - you need oil soluble film formers
-
@Moonie, as a purely theoretical discussion - I would put both oil and water-soluble preservatives into your formulation, especially if you don’t have any emulsifiers in the product, but also if you do.
I think it would be extremely unlikely for an oil-soluble preservative to get anywhere near water incidentally introduced into a product - migration wouldn’t happen at all without a lot of agitation. Water-soluble preservatives might have to be ground into your oils, but I think it would be worth it.Remember, preservation isn’t just a matter of keeping microbes under control - it’s also a matter of legal CYA, and protecting yourself/your employer from lawsuits. -
It makes a nice dusting powder mixed with talc or cornstarch…

When in doubt, start a new thread. In this case, please do.

Talk to the folks at Koster Keunen, they might be able to help http://www.kosterkeunen.com/
The VL-212 is a Japanese material (http://www.sy-kogyo.co.jp/english/sei/1_s.html) I’ve never even heard of it before, and without any technical information on it, I can’t suggest a substitute.This is the only other info I could find: -
If you put the supplier name also, you might be safer.
-
I agree w/ @nasrins - formula you posted is useless w/o INCI names
-
@heraklit - cosmetic preservatives have gotten a hugely bad reputation, largely because of junk science, fear-mongering, and invalid association with food preservatives. Their benefits far outweigh their risks. Aside from marketing claims, it would be an enormous waste of time, effort and money to replace all preservatives. (Which is not to say that people won’t try. Marketing advantage is a powerful thing.)

@lililapomme,
What is your target audience/demographic, and how much of a budget do you have for consultants? -
Precisely right, with two exceptions.1) Ingredients that are known colorants, and that have no possible use or benefit other than coloring a product. You will have a tough time getting this kind of product past the FDA. A good example would be plastic glitter.2) Any ingredient in a color cosmetic (one who’s main purpose is to impart color to the skin or hair) that contributes to the color is going to face a much closer scrutiny by the FDA than that same ingredient would face if it was formulated into a skin care product.

“Heavy metal” has a very specific meaning jn chemistry: http://en.wikipedia.org/wiki/Heavy_metal_%28chemistry%29
It is possible to get tiny amounts of metallic oxides in a raw material as contaminants from the reactor/manufacture/storage, but it’s very unlikely, and it would be even more unlikely for those contaminants to affect performance. -
SCC is a separate ingredient from green tea. You did ask for an alternative to green tea, didn’t you? You can buy a little here (a little goes a long, long way) http://www.ebay.com/itm/like/261450445347?lpid=82 or you can get me a fedex number and I’ll send you a some of the 10% solution in Glycerin that we use.Neither green tea nor SCC (or many other natural colors) are approved colorants.
-
Here’s a point that I don’t try to make nearly often enough - “active”/skin-benefit ingredients in cleansers (skin care/hair care), with very few exceptions, can NOT possibly do anything to help the skin. We do our customers a disservice when we suggest otherwise.
-
Sodium Copper Chlorophyllin is a deodorant. It is NOT an approved colorant for cosmetics or soap/cleansers, so it would be completely illegal in the US to use it to color your facial cleanser green. (It is OK in dental products. Go figure.)My understanding is that if you use it as a deodorant, or for any of it’s other properties, and you are definitely not using it as a colorant, it is legal to use in cosmetics, even if it does happen to have a green color. To be on the completely safe side, I would put a reference to the deodorant properties somewhere on the label.
-
Glyceryl Oleate has no heavy metal content. Neither do any other cosmetic ingredients. Where are you getting your information?
-
Sorry, but the ONLY way to know for sure is for you to have a challenge test done.
It would be irresponsible of us to tell you otherwise, since it might work, and it might not work, depending on what ingredients are used, and what microbiological load they carry to start with. No one can accurately predict preservative performance, even if you reveal your entire formulation.Many beginning formulators/entrepreneurs have a huge problem with this reality, but there is no getting around it.
