  • Fabric conditioning compositions and process for making them
    Patent number: 5411671
    Abstract: An aqueous fabric conditioning composition comprising a homogeneous dispersion of fabric conditioning active particles having a size distribution such that the particles have a mean size of about 0.7 to 10 microns as measured by Malvern Particle Size Analyzer and preferably have 10% of the distribution with a particle size of at least 23% of the mean particle size. The composition is obtained by a continuous process for making the aqueous fabric conditioning composition.
    Type: Grant
    Filed: January 5, 1994
    Date of Patent: May 2, 1995
