Is this foam or conditioner separation 1 hour later on top of product?

Posted by Abdullah on April 20, 2022 at 7:03 am

I made this simple conditioner an hour ago.

Water
BTMS 25 2%
Citric acid 0.2% to pH 4.
NACL 0.05%
Formalin 0.1%

Sample size 300g. Mixed with stick blender.

After sample was made everything was homogenous.
At bottling is was low viscosity but not water thin.
After one hour, there is a thin white layer on top as in photo.

Is this the bubbles introduced during mixing that is coming out of formula or the formula is separating?

Looks like foam to me.

Put it in an oven to warm it up and see if it disappears in a couple hours. If it does, it was foam. If not, it is separation.

It looks like foam to me too.
Heat it to 35 - 40°C. As you would do your stability testing.

Spray it with Isopropyl alcohol. If it’s a foam it will collapse.

I have ethanol. Does it work?

I understand that both ethanol and isopropyl alcohol have much lower surface tension than water and break foam bubbles. But I only tried it with isopropyl alcohol because that’s what I have

Simple recipe works well
Water phase
1. Water
2. EDTA 0.1
3. Glycerol 2
4. Cetrimonium chloride 2
Oil phase
1. Cetearyl alcohol 5
Heat separated to 78© add oil to water mix for 20 min
