Greetings,

I managed to incorporate Polyquart-10 and SLS into the formula and this is how I did it. I dispersed Polyquart-10 into water first and then added PEG-7. In a separate water I dispersed SLS and then added it to PEG-7, Polyquart -10 and water mix. Then I added SLES, BETAINE and DEA in that order followed by the rest of ingredients.

Chemicalmatt, I did this batch before your post but would try your suggestion too.

I used it on my hair and it foams quite well (like some of the premium shampoos) and hair feels soft and condtioned afterwards. However, there are too issues with this formulation: 1- It is irritating and 2- It caused a hair loss ( about 10-15). The ratio of SLES :SLS i am using is 7:3 (active ingredient). Could reducing SLS ratio have any effect on irritation and what is the best way to reduce or eliminate irritation while keeping both SLES & SLS? If that cannot be achieved I am happy to leave out SLS and increase SLES to maintain the good foaming if that is possible.
And what is causing the hair loss and how to stop it?

Your advice will be highly appreciated.

Thank you all.

Hi
Thank you for your conments.
I cannot find poly H81 where I am. I am based in the UK. I contacted a supplier and they quoted me for Dehyquart H81( INCI name: PEG-15 polyamine). I was wondering whether polyquart H81 and Dehyquart H81 are the same?

Thanks everyone for the comments and here I have some feedback. I made two 1 kg batches and the bubble problem is gone. This is how I did it:

Batch 1

• I dispersed xanthan into MPG (monopropylene glycol) in 1:3 ratio
• I heated water to 95 degrees Celsius and transferred it into a variable speed blender.
• While setting the blender to the highest speed I added xanthan into the blender in small amounts and blended it for 15 minutes continuously.
• Then I added the rest of ingredients and heated to 75 degrees Celsius with gentle mixing after addition of each ingredient.
• The final product did not have bubbles in it but there was a thin layer of xanthan paste on top of the mix and some clouds, which I thought to be some unhydrated xanthan, could be seen in the final product. However, these have gone after  1 1/2 to 2 days and  a nice thick and homogeneous product was produced.

Batch 2:

• I heated MPG to 50 Degrees Celsius and dispersed xanthan into it. Again the ratio of xanthan to MPG is 1:3.
• I  heated water to 95 degrees Celsius and transferred it into a variable speed blender.
• While setting the blender to the highest speed I added xanthan into the blender in small amounts and blended it for 30 minutes continuously.
• Then I added the rest of ingredients and heated the mix to 75 degrees Celsius with gentle mixing after addition of each ingredient.
• The final product was homogeneous and  no bubbles were present. No clouds could be seen either. It was success.     

Thank you all for your comments.

Thank you Mr Bobzchemist. I am sorry I should have included more details. The Xanthan (0.5%) is dispersed in Glycerine (5%) and then added to water which is about 66%. It has been only 50g batches so far. I have been doing it in weights rather than volume as it is easier to measure. So will changing the respective percentages affect the small bubbles or is it a mixing error? Last time I used a mixer to do it. Thank You
