Appeal No. 2000-1877
Application No. 08/881,457
1. A non-aqueous, liquid, heavy-duty detergent in the form
of a suspension of solid, substantially insoluble
particulate material dispersed throughout a structured,
surfactant-containing liquid phase, wherein:
A) said composition comprises from about 45% to 95%
by weight of the composition of a structured,
surfactant-containing liquid phase formed by
combining:
i) from about 50% to 80% by weight of said
liquid phase of one or more non-aqueous
organic diluents; and
ii) from about 20% to 50% by weight of said
liquid phase of an anionic surfactant-
containing powder which is formed by co-
drying:
a) one or more alkali metal salts of C10-16
linear alkyl benzene sulfonic acids; and
b) a non-surfactant salt selected from the
group consisting of alkali metal salts
of sulfates, citrates, sulfo-succinates
and mixtures thereof;
to produce a powder which contains from about
80% to 94% by weight of said powder of said alkyl
benzene sulfonic acid salts, from about 2% to 15%
by weight of said powder of said non-surfactant
salts and from about 0.5% to 4% by weight of said
powder of residual water; and which contains from
about 10% to 25% by weight of said powder of a
solid phase which is insoluble in said non-aqueous
organic diluents; and
B) said composition also comprises from about 5% to
55% by weight of the composition of additional
particulate material which ranges in size from
about 0.1 to 1500 microns, which is substantially
insoluble in said liquid phase and which is
selected from peroxygen bleaching agents, bleach
