Hand Wash Foam
Dear All
I’m trying to make a hand foam formula which is basically consists of SLES , CAPB and Glycerin .
I prepared it by mixing SLES ,CAPB, and oil base fragrance then i add it slowly to R.O water and mix until obtaining clear solution then i have checked the sample after 2 days and a white precipitation was found at the bottom .
What could be the reason for this problem ?

the fragrance, unless you have included things that you have not told us about

Dear @Belassi
Thank you for your replaying
I think also the problem coming from fragrance because i did experiment for each alone with water and there was not any precipitate -
Try using a solubilizer for the fragrance with high HLB like tween 20, tween 80 or PEG 40 hydrogenated Castor oil at 0.5-1% . This might solve slight instability issues
-
Try alternative fragrances. This is an unusual problem. It is usually possible to include 1% fragrance in a surfactant base provided the base has a sufficiently high proportion of active material.

Kingstone if you describe the complete list of ingredients and percentage then solution would be easy
-
if the fragrance is separating it’d rise to the top, rather than fall to the bottom
could you show us a photo of this precipitate?

@Bill_Toge - good point!
-
The Formula is
SLES 4 %
CAPB 3 %
Fragrance 0.1 %
Preservative 0.1 %
All those ingredients mixed together then added slowly to the Aqua (92.8 %)unfortunately i can’t capture photo because once i mix it ,the precipitate solve it self in the solution !

I make new sample by adding Tween 20 , i will update you what happen
-
try adding the ingredients one after the other, instead of mixing them together
what preservative are you using?
