@Belassi I am with Univar but again what has been done where we can help, nada. If an effort has been made then we can participate, handing out formulas is not sustainable by any means.
-
I concur with @ozgirl, i do such products extensively but just asking for formula directly is a tad too much. There are lots of suggested formulas available online, little efforts go long way.
-
Google and you will have zillion results to choose from.
-
Ashish IIRC it was Lavanya range from them which was specifically stable in my hair gel, kept it out in hot sun for pretty long and it was perfect for my standards.
-
Ashish I have used some very stable water soluble dyes from Neelikon, you can check the oil soluble part as well with them. I had a specific issue with pink/red (water soluble) and Neelikon was on top in terms of the stability.
-
I am definitely inspired @Belassi, thanks for the update and thorough ideas.
-
Thank you, already on to it.

You are right Martina, Acusol OP305 @ around 0.25-0.5% will give you enough opacity. Add it last in the formulation after diluting with batch water, also the pH should be around 7-8.
-
Hope it works for you this time!!!

Try to bring C-25 to 25%, cut down PEG-1 Glyceryl Cocoate to 5%, go up to 15% with glycerin & PG (7 & 8% resp.), eliminate the bottom 3 components. Once you have the solid set in formula, play with the last 3 through knock out trials. I have a perfect formula and I just spelled it for you. I just use Tween 20 upto 2% instead of those PEG-40 HCO & Polysorbate 80.
-
Very well said Bob.
-
Given a chance I would use c-25 only, that was just a piece of information about c-20. Stick to what Bill has suggested, it would work out. I just put my lab sample in cold water of around 3-4C and it sets nicely. C-25 will probably work better as it has a higher melting point compared to c-20.
-
I was able to get the same with Ceteareth-20, removed that PEG-& Glyceryl Cocoate and without any resin. As Bill said you need to jack up the dosage of Ceteareth-25, FYI I used almost 15% of same humectants combined. But to increase the melting point or the lets the formula strength I have used PEG-8 Beeswax. The problem is slight haziness but I am sure with right quantities it can be optimized. I chucked out those 2 solubilizers, instead I used Tween 20. So far it looks good and clear to me. Need to test it at 45C now to monitor the clarity and hardness.
@Bill_Toge Bill do you think it is going to make a big difference if I substitute C-20 with c-25, as the latter has a higher mp of around 49C while c-20 has around 45C. -
@johnb thank you.
-
wow @chemicalmatt, so I am in a bit of a confusion here and that means I have to modify my formulation now. Its very stable and approved for all the features.
The issue as you said is redeposition where I have used certain silicone emulsions and which are to be deposited on the hair. Then I have a chelant called Dissolvine GL 38 and now I am having second thoughts since as you mentioned it will retard redeposition. -
I suppose and if I am right then @nouna76 is basically asking how to dissolve SLES faster as their heating system broke down and they can’t use it any longer.
I have seen recently in my laundry formulations that if I add sodium carbonate to the batch @0.25-0.50%, the dissolution is faster compared to normal. Trial and test first though depending on your final formula and if you are flexible enough to incorporate Na Carbonate. -
@Belassi that’s why I mentioned the Lifebuoy reference, have done it in lab but not with Akypo of course. The pH was around 9 almost.
-
I ignored the fact that the product is from Kao so I would accept the product as it is, it is soap based and and the pH must be above 8 surely.
No confusion here @johnb, just a different perception. -
I doubt if they have mentioned the complete LOI, if it is high pH product solely depending on alkalis then I don’t think that calcium chloride is needed here until and unless you have used few enzymes which would be stabilized by it. The silica of course is an abrasive here if I am not mistaken, that ethyl palmate again is to control the suds here and used as a hydrotrope, I use potassium cocoate in such household and industrial formulations. Suds (foam) has to be controlled here as it is machine recipe and you don’t want your machine overflowing with foam.
I am not sure how efficient is this green thing. -
I would check the pH first to make any judgement, if it is 8 and above then it is definitely soap based. If not then synthetics are main here and the rest of the LOI is just a hogwash, ignore. Also this comes quite close to the LOI of Lifebuoy hand wash which is based on these fatty acid soap, you can tell by the look of it.
-
Bergerac & International Lacquers come to mind from France and Luxembourg respectively, not sure if they are still up and running as it is almost a decade since I handled such things.
-
A very versatile product indeed that Akypo thingy!!
-
I was able to hit the jackpot with the first try, I didn’t even use 25 ethoxylate as I had 20 ethoxylate sample and it came out absolute delight to my surprise. I have IKA overhead mixer with impeller and I could control the speed nicely once the ethoxylate was added to water phase. Processing temperature was around 80C and I poured it at almost 55-60C, set nicely almost like the benchmark I was given. But that leaves with a big question here, when do I add my preservative as the pouring temperature itself is too high.

Check Dow Corning automotive care, there are endless formulations and suggestions. How about mixing a silicon gum in volatile with little phenyl trimethicone for shine, can be made sprayable.
