Use a cellulose polymer ie natrasol 250HHR to avoid thixotropy in storage with 1% Wt cetyl alcohol plus emulsifier brij 721
-
You need a surfactant/s based on HLB of hydrophobic polyphenol? to blend into emulsion with water phase containing the soluble hydrophilic ingredientsPolysorbate 80 HLB with HLB of 15 may be too high.
-
minimum viscosity for suspension is 5000 cps
-
not sure -just made changes substituting for functional equivalency when needed.
-
This looks like Mallard reaction taking place over time between free glucose in AG and amine group in Tranexamic acid .Try a knockout to confirm.
-
Not normal to use quat in shampoo due to incompatible charge effects with anionics. Better to use a cationic polymer such as cationic guar if you can source it.
-
hydroxypropyltrimonnium guar is good for wet/dry comb reducing hair breakage and does not build up with repeated washings
-
Heat all surfactants to 60-70C and Peg 150.
-
use an antioxidant such as VE -should drop right in
-
Starches can also discolor depending upon the SAA used example particularly SCI maltodextrin is a safer binder alternative
-
Use acyl isethionate with cationic guar and glycerine
-
hydroxyethylcellulase ie natrasol 250 HHR
-
I would contact supplier first and have them do it:or use other functionally equivalent materials.
-
suspect you may be using wrong Carbopol with CG surfactant-try C-1342
-
usually the marine material ie sea moss and blackthorn oil-
-
best off having color removed from raw materials prior to formulation.Make sure color is not coming from reaction/discoloration in storage.Net/net what is the source of the problem?
-
increase stearic acid to 6-10% for bar firmness and after feel.You can also add free sodium isethionate 2-3wt %
-
claims will determine types/levels of surfactants:nonionics uch as Tweens very drying to hair and consumer perceptable.
-
Then it was very time consuming:had to get an ACS number first and show chemistry/prove structure for new raw material before submission to panel Good Luck
-
procetyl aws works at 2:1 ratio because of having both a hydrophobic and hydrophilic moieties.
-
I have but about 25 years ago at 150 USD/HR. I would upgrade to todays standards and charge 225/HR
-
YES
-
replace cocamide mipa with cocamide dea or at ph 5 use cocamidopropyldimethyl amine oxide
-
use 2% peg 140 distearate and add to water phase with surfactants before heat to 60-70C
-
Ascorbyl glucoside is a stable analog for VC
