You think you can try to dissolve that precipitate in water and see if it completely disperses or not. Should give you an idea what it could be.
-
Subjectively speaking, I had this divine feeling of washing myself ASAP after trying few of these oils in my lab to know the feel.
-
How acidic is the shampoo that you require such high amounts of alkalis to bring it to the acceptable pH level or is it a neutralising shampoo for some post keratin/acidic hair straightening treatment.

Dissolvine range from AKZO, specially Dissolvine GL 38 and Dissolvine 47S. Tetrasodium Glutamat Diacetate is the INCI name.

@Doreen after sincerely reading your post I am guessing Makeup2018 will stick to the laid rules. Next post will be by Makeup2050????
-
Let me guess, one of the components of your essential oils. Have seen it with dipentene paneling a top class heavy duty HDPE 10 gallon bottle.
-
wow sampling for you is a mammoth task then.
-
@Belassi Univar??
-
What’s the product here, I have seen similar issues with few formulation types specially in home care.
-
@Gunther can’t you request a sample from a distributor
-
I have seen huge improvement @0.05%, you can request lowest MW variant as well which is Polyox WSR 205 aka PEG 45M.
I use Polyox WSR 301 and generally make a stock solution of 1% concentration.
PS: The slip properties are phenomenal and most shaving products has PEG 90M if you have noticed in the LOIs of many shaving products. -
Polyox WSR is the brand name, I am using Polyox WSR 301 and the slip it gives to the formulation is unmatchable. But that’s me, every technician has a different perspective for such enhancements. By the way it’s called PEG-90M if that strikes something very familiar.
-
I have a similar product like the one @Belassi mentioned except that instead of alkanolamide it has CAPB. The product is one of the best I have used. Comes from LG chemical division.
-
@Belassi wish you could get hold of the Dow polymers, they are phenomenal even @0.05% in such applications. With and without gives a clear indication of apple and oranges.

Chelants and enzymes together is a big no, in fact you need to feed extra calcium in salt form to keep them active. Also the temperature is a very critical point to be considered. Ratio of nonionics to anionics will play a role too. Novozymes has good information for such systems.
-
Check your pH as well, have seen many times in lab lower pH enhancing the pearl effect.
-
Nope, it is the cellulose issue. Maybe cheap formulation being thickened with cellulose. Sorry won’t work.
-
Be leaving it in Arctic conditions. You need to elaborate more the term shelf life.
-
Did you try to knock out Allantoin just in case, there are umpteen discussions on this forum on similar experiences with Allantoin.
-
Don’t forget to homogenize the ZPTO, helps in suspension with the reduced particle size.
-
Seems like a typical dish wash recipe, everything depends on the dosage of each ingredient and what’s the AM you are targetting among other things like final pH, viscosity, etc.
-
One step at a time, just remove the 25 and use ceteareth-20 only. Use at least 20% minimum and adjust in water. Take it from there depending how it comes out.
-
@Frin I gave up color cosmetics long back, wish I could chip in. But let me go back to my earlier records, think I had something similar but in stick form which was matched against non-transferable Sephora flat liner. Maybe you can modify that one to suit your needs.
-
@Gunther the name is self-explanatory, the LOI bloomed into 56 ingredients for marketing ??
-
Sad scenario, this is just absolute fear mongering based on whims and fancies.
