You can use SLS, ALS, ALES, or SLES in combination with Cetyl and Stearyl Alcohol.
e.g Here’s an ingredient list for M.D. Forte’s product.Water (Purified), Ammonium Glycolate, Glycolic Acid, Cetyl Alcohol, Stearyl Alcohol, Sorbitol, Ammonium Lauryl Sulfate, Methylparaben, Propylparaben -
to figure out what is causing the color change, we’d need to know all the ingredients in your formula.

Yes, if you thicken with an acid/base you need less salt.
I don’t think you will get much advantage from MgCl versus NaCl.Downside of MgCl is it makes it like you are washing your hair in hard water. This has the potential to be dulling to your hair. Although maybe there wouldn’t be enough of an effect to notice.You can probably use 2% or less of MgCl without a problem.You should do a salt curve analysis. -
Not at the moment. I will have to find/write something.

Interesting. Our RT was always 25C +/- 2C
-
Just curious, how is RT different than 25 C?
-
In the US at least, the term ‘hypoallergenic’ doesn’t have any legal meaning and pretty much anyone can use it.
I’m not sure how you would say your fragrance is phthalate free when the “free from” claims are being banned. In the US you could still say it. -
You could also try using different surfactants that aren’t as good at cleaning. What is the surfactant that you are using?
-
Our stability test decisions were made after 8 weeks for formulas in which just the fragrance was changed. 12 weeks was always the official decision on pass/fail. Storage temp was 4C, RT, 37C, 45C

According to the C&T article, their idea of pollution is UV rays and dryness.

@mikebavington - for a small company, a higher price is better than a lower one.
-
Great question. For Chemists Corner products, I have just used Paypal, a hosted blog, and WordPress. If that doesn’t work for you, you can take a look at Amazon. They have an order fulfillment system.

Yeah, there is nothing special about lactic acid. In fact, we used citric acid in our conditioner formulas. It’s possible their purchasing agent got a good deal on lactic acid.

I can verify that big box stores like Walmart and Target have a big say in what type of personal care product gets launched. At my former company, nearly 40% of sales came from Walmart. So, if Walmart didn’t take our new product offering it would automatically fail in the marketplace. Therefore, when Walmart said they wanted something done a certain way, we almost invariably did it.

@Herbnerd - we are working on getting back the old information. Hopefully, in early 2014.
-
@Herbnerd - thanks for the clarification!
It’s good to hear some countries take dietary supplement regulation seriously. In the US, it’s pretty much anything goes as long as no one can prove you’ve killed someone. -
Welcome aboard everyone!
-
You started selling a product before you knew it was stable and possibly with a compromised preservative system?
The lack of regulation in the dietary supplement industry in the US unsettling.
-
@milliachemist - great points. Saying something is “anti-pollution” is a puffery claim so it’s fairly easy to prove your product does whatever you’re saying it does.
-
Staying under the radar is one method. It is up to patent holders to track down infringers if they want to collect damages. As you can imagine, this could be costly.
More reputable companies just use amounts of the ingredient outside the concentration range. -
The silica would be my guess.

@pma - Interesting studies. They were pretty small though <20 subjects in them all and they didn’t provide an adequate control in my view.
They did what many people do when investigating cosmetic products / ingredients. They missed the most important control.In these studies, the question isn’t whether Vitamin C can protect skin from the sun, the question is can Vitamin C protect skin from the sun better than the best technologies (e.g. traditional sunscreens). Since they didn’t include them, I’m guessing the answer is ‘no’.Therefore, for a formulator the best strategy would be to create a sunscreen using traditional sunscreens and add a drop of Vitamin C to make the claim that it is in there. -
Ah. Well, 20% and 10% seem pretty high but not unreasonable. You might get an even better product if you used a small amount of SLES (sodium laureth sulfate) too.
-
I think it the reality is that consumers can’t tell a difference whether their vitamin C is oxidized or not. All that matters to people is that they are putting something on their skin that says Vitamin C. The things that make the formula actually work (moisturizers, occlusive agents, etc) are what’s responsible for whether people like a product or not.
For the most part, unless you’re getting a prescription dose of Retinol, vitamins in cosmetic products have no effect on the results. At least I haven’t seen any real-life evidence that they do. -
Is that % active in the formula or % of the raw material? Also, could you clarify what your acronyms stand for?
SCI = ?DLSS = ?
