Probably because you can get other things that work as well for less money if you’re a big company. Although I remember Germall Plus being one of the ingredients companies tried to sell us. There was just no reason to use it since it was more expensive than DMDM Hydantoin & not more effective.
Incidentally, Germal Plus uses a formaldehyde donor (diazolidinyl urea) for it’s functionality. -
I think in the old days it was human babies. Now it’s probably cows or pigs.

I was just shaming a company today on social media due to selling contaminated products.
“Congratulations on producing dangerous, microbial contaminated products @gilchristsoames How about using a proper preservative next time?”That was in reference to a recent product recall they experienced due to microbial contamination. -
inCosmetics is good. The Suppliers Day by the NYSCC is good too. They are more raw material focused but that includes things like actives.

Hello new students!
I’m looking forward to hearing your questions and comments about formulating with natural ingredients.Feel free to post any questions that occur to you as you go through the course. -
Thanks for the follow-up. Even negative results are useful information.
-
And for preservative challenge tests this is a reliable company. Cosmetic Test Labs
@The_Microbiologist runs the company. Also, you should see this discussion about microbial questions if you haven’t.I also agree. Use the maximum level as suggested by the raw material manufacturer if you can. -
Bob is right. I’ve seen no evidence that Hyaluronic acid can penetrate the skin.
-
Does it work? I guess that depends on what you want it to do. It’s likely a humectant and has some potential moisturizing ability. But it’s highly unlikely that it’s going to “provide rebirth to the skin”.
I believe it’s just a marketing gimmick. -
Here’s a pretty interesting write-up of the history of placenta used in cosmetics.
The marketing spin was that the placental ingredients could “provide rebirth of the skin, thus enabling the skin to remain in the ‘bloom’ of babyhood; … would provide one with a younger appearance and with a look that was ‘incredibly younger’; … would provide both a softening effect and a tightening effect on the skin; … would overcome the effects of age on the skin, ‘age signs around the eyes and mouth’ and wrinkles; and … would impart a youthful elasticity to the skin which would banish the drying, faded look of age.” -
@Belassi is correct.
However, this was a pretty common occurrence with some of our conditioner formulas. Viscosity might double for some formulas. Mostly this didn’t happen but we still passed some formulas which did this but were otherwise stable. -
@milliachemist - the 1991 edition is still relevant. 80 - 85% of the information is still accurate. Not much changes in the cosmetic industry when it comes to technology.
-
Bob is right, that is a huge undertaking.
I’d start with first identifying all the areas / procedures that require SOPs. A mind map would be good for this but I would include…1. QA / QC - tests done on raw materials & finished products2. Product development - tests done while making products (performance)3. Required testing - Stuff you need to do to launch a product (e.g. stability, safety, etc)Once you get a list of every possible procedure you could reasonably imagine, then you can rank them by the amount of work required to write them.Then you could decide which ones to start writing & get started.Then you have to validate them.3 years later you should be in pretty good shape. -
@milliachemist - You can get the latest Harry’s book through Amazon. It’s not online as far as I know.

Our Beginning Cosmetic Chemistry is a good one for beginners.
But surfactant science hasn’t changed much since 1991 except there is more of an emphasis on plant derived starting materials. Also, some of the trade names may have changed. -
@David - yeah pretty much.
This thread inspired me to investigate it a little further. Here’s a little more detail on water used in formulating. -
The pictures are not accessible. You can post pictures directly by clicking the 6th icon from the left and pasting the link. Or give us access to your Evernote page.
I haven’t worked on any similar system & can’t see the pictures so I don’t know how much of an answer I can provide. But when you get separation that means your ratio of emulsifier to oil is not right. Decrease oil or increase starch would be what I would try. -
Deionized water works but demineralized works too.
-
Shouldn’t they list their organic ingredients outside the LOI then include a proper LOI?
-
They also don’t follow proper labeling rules. Putting the term “organic” in an ingredient list is not correct.
-
Cetrimonium Chloride is limited in the level you can use for a leave in product. I wouldn’t go higher than the CIR reviewed amount in a leave-in product.
“The CIR Expert Panel evaluated the scientific data and concluded that all three ingredients were safe for use in rinse-off products and were safe for use at concentrations of up to 0.25% in leave-on products.” - See more at: http://cosmeticsinfo.org/ingredient/cetrimonium-chloride -
Yeah, I would suggest using the liquid soap for hand washing and just start from scratch for a shampoo. You can make a nice one out of SLES / Betaine or create a more mild one with Decyl Glycoside.
-
When I was formulating the best foaming product was always Pantene which is based on SLS/SLES. So, while there might be some differences it’s pretty clear that at least some cosmetic formulators can make an excellent foam with SLS/SLES.
Also, SLS and ALS were the same price so it wasn’t a pricing issue (at our company anyway). -
Yes, in this forum they are called “announcements” and always stay at the top. It might be better to make a link to a page of discussions though.

Chemicalmatt is one of the people on this forum. He works for a contract filler/manufacturer and might be able to help with your project.
