Why not just make a w/o emulsion???? Although with the amount of info that you have given it’s not possible to comment further.

[Chemist77]

Well while agreeing with all the learned specialists here my first change would be elimination of castor oil pigments and use silicone compatible or coated pigments. Then I would look for further trials. Get rid of kaolin as well if you are using it as a filler or mattifier and look for other options compatible with this kind of formula.

[Chemist77]

Generally there is a tabular comparison about the compatibilities and if you search it online I am sure you will find everything about it.

[Chemist77]

Agree with @David.

[Chemist77]

Yeah mine ain’t soap, but great help there @Microformulation.

[Chemist77]

Great suggestion @Microformulation as I have been looking for an ingredient which can effectively neutralize the odor of pet urine in household products.

[Chemist77]

I would try removing the oil as well as a knock out and see while keeping the alcoholic extracts.

[Chemist77]

Try changing the preservative and see where it takes you; as Christopher pointed out, it might be that case and I guess we had a discussion about in the past as well where salicylic acid in a mask was giving purple coloration. 

[Chemist77]

@sattar How about you do the trial and check how it comes out with salt only, with amine oxide only and with a little of both????

[Chemist77]

Guess your best bet would be to inform the supplier and as a manufacturer the company would be compelled to give you the best solutions rather than taking back the delivery. Inform them the solvents you have and if they can guide you with these then well and good and if not then they will let you the best option. This way you learn something new and avoid the need to return the delivery.

@Belassi where can I source this horny potassium hydroxide )

[Chemist77]

I suppose it must be so at 30% level.

[Chemist77]

It’s just a wild thought that crossed the mind.

[Chemist77]

I have the specs and the pH is mentioned between 10-11 (although need to check if it is as is or 1% solution) but I do have noticed a jump in pH after the addition and then I generally use citric acid to bring it down. But my point is again the efficacy of the chelant at such acidic pH of 4-5.

[Chemist77]

Guess @Belassi has a strong point, I bungled up between acidic and close to neutral.

[Chemist77]

Yup I forgot to bring up that point @Bill_Toge, secondly it depends on budget cost as well if 940 or Ultrez.

[Chemist77]

Looking at the formula I suppose the pH is in an acidic range where the strip is not registering a color change and it doesn’t look like a w/o emulsion too. Or make 10% aqueous solution of your lotion and try measuring the pH.

[Chemist77]

@MarkBroussard I am using Dissolvine GL38 in my balsam conditioner (rinse off), but the only downside I feel is that it takes pH too high and then again I need lot of citric acid to bring it below 5. Now my point is the efficacy of the chelant at that pH because generally most of the chelants have very high pH as such.

[Chemist77]

As @Bobzchemist out that it might be on its way out I think this is one of the reasons why such products have lost the sheen and consumer acceptance. Not too many such products are seen in the market now.

[Chemist77]

@Ruben I think it would depend on the type of formulation too, maybe in an anhydrous formula it is perceptible but in case of a regular oil in water emulsion I doubt if 0.25% can be felt on skin. But this is my perception, @Belassi might be correct in his observation.

[Chemist77]

I have used 940 with upto 65%% dosage for sanitizer and it holds pretty good, though I add a little glycerol to plasticize and avoid the balling of polymer in ethanol during application. With 30% you can get good viscosity of a typical gel.

[Chemist77]

TCC used to be a fav one, though not sure about its current status.

[Chemist77]

@joseg guess I don’t need to chip in as already @Bill_Toge & @Belassi have solved the issue. The only thing I would like to add is that complete information ex

[Chemist77]

@joseg could you give a bit more idea about your formulation because making assumptions about formula outline isn’t gonna help.

[Chemist77]

I second @Perry and @Chirag, I am using EGMS and it gives a beautiful pearly effect sans sedimentation, though acumen for formulating is needed even for the simplest formulas. Have learnt here only the importance of knock out and substitution techniques, and voila it gives a whole new dimension to formulating. Experienced it recently during dishwash and liquid laundry detergent formulations’ optimization.
