Abstract
Soap, combo or syndet bars are filled with particulate inorganic filler materials wherein the particles of the filler are coated with fatty acid which has reacted chemically with the filler.
Claims23
A synthetic detergent, a combination of soap and detergent or a soap, each in bar, form comprising particulate filler material capable of reacting chemically with fatty acid wherein the individual particles of said filler are coated with fatty acid that has been reacted with and is chemically bonded to said filler.
A process of forming a filled synthetic, a detergent combination of detergent and soap or a soap such each in bar form comprising particulate filler material capable of reacting chemically with fatty acid wherein the individual particles of said filler are coated with fatty acid that has been reacted with and is chemically bonded to said filler which comprises the steps of:
- (a) drying said particulate filler material,
- (b) treating said dried filler material with a first fatty acid at a temperature of about 95.degree.+5.degree. C. for about 0.5 to 2.0 hours so as to coat said particulate filler with a reaction product of said first fatty acid and said filler,
- (c) slurrying said coated particulate filler in either
- (i) a second fatty acid and then saponifying said second fatty acid or
- (ii) a synthetic detergent based syndet or a combination of detergent and soap or a soap composition, and
- (d) forming bars of synthetic detergent, combination of soap and detergent or soap from the resulting compositions,
- with the proviso that said steps (c) and (d) are conducted under such conditions as will safeguard the integrity of at least a substantial portion of the coating applied to said particulate filler in said step (b).
