Abstract
The invention relates to solidification of liquid anionic surfactants with a binder, carrier, or both binder and carrier to form a solidified surfactant composition. In particular, the invention relates to solidification of liquid surfactants utilizing drying device(s), wherein the feed composition contains at least one liquid surfactant and the binder, carrier, or binder and carrier to form a solidified surfactant composition. The solidified surfactant compositions can be useful in various cleaning compositions.
Claims13
A solidified liquid surfactant composition comprising:
- a liquid anionic surfactant comprising an ether sulfate surfactant;
- a solid binder comprising a polyethylene glycol (PEG), wherein the PEG comprises PEG 1450, PEG 3350, PEG 4000, PEG 4600, PEG 8000, or combination thereof;
- wherein the solid binder and the liquid surfactant are in a ratio of between about 4:1 to about 1:60 by actives;
- a carrier comprising an alpha olefin sulfonate having a water solubility of about 0.2 g/L or more at 20° C.;
- wherein the carrier and the liquid surfactant are in a ratio of between about 2:1 to about 1:20 by actives;
- wherein the composition is a powder and the liquid surfactant is solidified in the composition,
- wherein the solidified surfactant composition contains at least 45 wt-% active anionic surfactant;
- and
- wherein the solidified surfactant composition has less than about 5 wt-% water.
