Hi, I need your advice on making my conditioner less thicker. My formula is:
A To 100 Water
A 0.5 Hydroxyethyl cellulose
A q.s Potassium Hydroxide (to bring pH above 7 and thicken the HEC)
B 2.0 Behentrimonium Chloride
B 5.0 Cetearyl Alcohol
B 2.0 Shea Butter
C 5.0 Polyquaternium-7
C 1.0 Dipropylene Glycol
C 0.6 Fragrance oil
C 0.5 DMDM Hydantoin
C 0.5 Potassium Sorbate
D q.s pH adjuster (to 4.0-4.5)
The result is very thick. It is really difficult to pour into the bottle. Even when I flipped the bottle and wait for a day, it won't go down. I tried the pump bottle as well, and the pump won't work, because the consistency is too thick, it won't fill the gap/hole where the parts has been taken out by the pump. I even added Dipropylene glycol hoping for the thinning effect, but it won't work either. I'm looking for more like butter consistency which can be pumped from bottle.
1. Should I remove Hydroxyethyl cellulose? I'm afraid it will affect stability as this is the only rheology modifier in my formula. (Actually i tried remove this already, but its still too thick).
2. How do you guys bottle a conditioner? I looked at some youtube videos, they pour it while it is molten. But with this method I cannot adjust the pH and give the heat-sensitive ingredients. (because adjusting pH must wait till 25C room temperature).
3. Do any of you ever use PPG20 methyl glucose ether? Is this good for conditioner?
Thank you guys, I really have no luck in making conditioner. I really feel there's something wrong that I did not notice until now. Sorry for the long and many questions I have.
Warm regards,
Vincent

@crillz according theory, behentrimonium chloride is cationic which mean it can irritate quite easily. and cetearyl alcohol suppose to counter that irritancy. anyway i will try to make it 1-2% then.
Thanks guys
Remove shea butter
You are applying it to hair not scalp and then it is rinsed. So don't wory about irritation.
Now I'm doing the freeze-thaw cycle for stability testing. Usually on cycle 2-3 the water always separates. Hope this time it works, so I can have a simple and stable conditioner formula.
Will update you guys if the formula works and stable
But this would be a great opportunity to do a knockout experiment.
I do not change the formula too much, because I'm afraid it won't function as it supposed to.
But I'm suspecting there is a misunderstanding here (Maybe I got it wrong). Usually at IPCS they always write the formula using trademark. For this recipe, they just write it 5% polyquarternium-7.
After I do little research, it seems the most commonly available polyquarternium-7 is in liquid form (which the active content is only around 9%). (My polyquat-7 in my lab is also liquid).
In this case, if we add 5% of this polyquat-7, it means we only add an active content of 0.45% which is in your range (not more than 1%).
What do you think? I never play with other polyquat (not even polyquat-10) because of the availability in my region.
Thanks so much Perry
