To see any transfer-proof properties, the non-volatile oil must be reduced to no more than 5%. And that encompasses your oil-dispersed pigment as well. Also, try increasing the TMS. Experiment with 6, 8 and 10% and see how it goes.

Hi Perry,
After the “Down for maintenance” yesterday, I can’t seem to be able to post “New Discussion” but I can only post reply. I’m using Chrome as well as Edge. After I clicked the New Discussion, the page turns opaque with no popup window.

Pharma said:Coco betaine and cocobetaine are the same whereas cocamidopropyl betaine is not. Both are amphoteric surfactants, the former betaine with one of the methyl groups substituted for a mixture of short carbon chains derived from coconut oil (likely mainly decyl and dodecyl) whereas CAPB is betaine with an aminopropyl chain instead which in turn is bound to fatty acids from coconut oil by amid bonds. CAPB should, according to empirical theory, be milder.See graphical illustration for chemical structures HERE.
Thank you.

It’s stated other name for Cocamidopropyl betaine is also cocobetaine.
I argued that it is not correct but according to another person whom I asked, she said
” this is again incorrectly decoded. Cocobetaine is not the same like INCI: COCO BETAINE. This is actually a very unlucky thing, but CapB in the daily language (other names) is called cocobetaine. In other languages the mixup is less likely, see Kokosbetain (=cocobetaine) vs coco betaine. I agree, this was a very unfortunate choice, but what they put there is correct. It was not the INCI COCO BETAINE mentioned. I would conclude that the book needs attention to details. “Hence, my confusion.

@deneuxben you might want to check this out, see if it helps.

@ozgirl Yes, I have seen the 3 Danox formulas mentioned. I just want to experiment beyond the basic sample formulas.
I definitely experiment further. Thanks

@Pharma thank you for responding. The suggestion to use hydrotrope is to improve solubilization. My formula contain approximately +/-20% water /water soluble ingredients.
I noticed some liquid droplets in the conditioner bar with Danox HC-30 which I did not see in other conditioner bars such as with Emulsense HC, Varisoft EQ.
This liquid droplets will also be an issue when it comes to packaging in a box.I’ve never worked with hydrotrope before, so this is something very new to me.
biofm said:What quantities of the caprylate, caprate or both would work for your trials?I have no idea how much is needed in a formula as I’ve never work with it before. If there is not much of alternative, I will go ahead with sodium xylene sulfonate.
I have tested with both propylene glycol and SXS (40%). Both at 2% and after 24 hours, no liquid stain coming out from the PG but with SXS, the bar still has some liquid out. With 2% PG, it does lower the setting temp slightly. I’ll be experimenting with different % and see how they perform.

biofm said:How about potassium caprate/caprylate?
@biofm I’ve tried to find both Potassium Caprylate and Potassium Caprylate/Caprate and so far, no where to be found in small quantity, since I am testing out.
ketchito said:@hubahubister Propylene glycol has also some hydrotropic properties, of course, not as potent as SXS, but it’s worth to try.I will definitely give this a try. Thanks.
