Process for preparing fabric softener compositions
A process is disclosed for preparing a fabric softener composition containing a quaternary ammonium salt, and a silicone or organic oil. The process involves forming a thick phase aqueous dispersion of the quaternary ammonium salt with the silicone or organic oil, and further admixing additional water to form a fabric softener composition.
1. A process for preparing a fabric softener composition comprising:
I) mixing;
25 to 55 wt % A) a quaternary ammonium softening compound,
1 to 20 wt % B) a silicone or organic oil,
0 to 4 wt % C) a nonionic surfactant, and
sufficient water to total 100 wt % of the components,
to form a thick phase dispersion,
II) admixing additional water to the thick phase dispersion to form the fabric softener composition,
wherein the weight ratio of the additional water admixed to the thick phase dispersion is from 0.5 to 2.
2. The process of claim 1 wherein 0.05 to 5 wt % of D) an inorganic salt is added in step II).
3. The process of claim 1 wherein the silicone is a polydimethylsiloxane.
4. The process of claim 1 wherein the silicone is an amine functional organopolysiloxane.
5. The process of claim 1 further comprising step III) shearing the fabric softener composition.
