Abstract
Synthetic detergent formulations are made by spray drying an aqueous dispersion or emulsion of a synthetic detergent and a hydrophobic plasticiser and optionally a filler to pr duce a particulate product. In particular the synthetic detergent includes mild surfactants such a fatty isethionate or sulphosuccinate surfactants. By spray drying the emulsion or dispersion, a particularly uniform product is made which can readily be formed into synthetic detergent bars which may include soap to form combination bar products (combi-bars).
Claims20
A method of making a formulated synthetic detergent product, which comprises:
- a) forming an aqueous dispersion or emulsion of a synthetic detergent and a hydrophobic plasticiser;
- and
- b) spray drying the dispersion or emulsion,
- to produce a particulate product including the synthetic detergent and the hydrophobic plasticiser.
A detergent material which comprises a synthetic detergent and a hydrophobic plasticiser in substantially homogeneous dispersion and having a weight average particle size of from 150 to 1200 μm, in free flowing non-dusting particulate form.
