Abstract
Synthetic detergent formulations are made by spray drying an aqueous dispersion or emulsion of a synthetic detergent and a hydrophobic plasticizer and optionally a filler to produce a particulate product. In particular the synthetic detergent includes mild surfactants such as 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).
Claims28
A method of making a formulated synthetic detergent product, comprising:
- a) forming an aqueous dispersion or emulsion of a synthetic detergent and a hydrophobic plasticiser,
- b) spray drying the dispersion or emulsion, and
- wherein the synthetic detergent comprises at least one sulphosuccinate salt.
A method of making a formulated synthetic detergent product, comprising:
- a) forming an aqueous dispersion or emulsion of a synthetic detergent and a hydrophobic plasticiser,
- b) spray drying the dispersion or emulsion, and
- wherein the synthetic detergent comprises one or more non-ionic surfactants selected from the group consisting of alkyl polysaccharides, sorbitan ester alkoxylates, glucamide surfactants, alcohol alkoxylate surfactants, and carboxylic acid ethoxylates.
A method of making a formulated synthetic detergent product, comprising:
- a) forming an aqueous dispersion or emulsion of a synthetic detergent and a hydrophobic plasticizer, and
- b) spray drying the dispersion or emulsion,
- wherein the synthetic detergent comprises at least one betaine derivative, imidazoline derivative, or fatty amphoacetate amphoteric surfactant.
A method of making a formulated synthetic detergent product, comprising:
- a) forming an aqueous dispersion or emulsion of a synthetic detergent and a hydrophobic plasticiser,
- b) spray drying the dispersion or emulsion, and
- c) at least one sulphosuccinate salt,
- wherein the aqueous dispersion or emulsion further comprises a filler of an inert finely divided particulate material having an average particle size of less than 50 μm.
