Abstract
Abstract This invention concerns the use of certain biogradable detergents containing as their sole active surfactant component linear, paraffinic alcohols containing 6 to 18 carbon atoms. These fatty alcohols have good laundering activity particularly to launder soiled cotton. These alcohols can be formulated in an aqueous solution containing only builders or optionally they can be formulated as multicomponent solid detergents in the form of a homogeneous, free-flowing powder. Using standard laundering tests these materials function well as detergents at low concentration levels, exhibit comparable or superior surfactant activity to sulfonated alkylated benzenes in the removal of soil from cotton or other cellulosics.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A free-flowing solid homogeneous detergent composition suitable for laundering soiled cotton, consisting essentially of: (a) from about 5 to 45 parts by weight of at least one fatty alcohol surfactant containing 6 to 18 carbon atoms, said alcohol or alcohols being the sole surfactant present; (b) from about 5 to 95 parts by weight of inorganic builder selected from the group consisting of sodium carbonate, sodium bicarbonate, sodium metasilicate, sodium sulfate, sodium chloride, sodium orthosilicate, and sodium sesquicarbonate; (c) from about 1 to 10 parts by weight of at least one of the following detergent adjuvants: anti-redeposition-compounds, heavy metal sequestering agents, optical bleach agents, whitening agents, corrosion inhibitors, tarnish inhibitors, and germicides, and (d) from about 5 to 45 parts by weight of finely divided, water-insoluble, chemically non-reactive inorganic absorbent, passing through a 365 mesh sieve and having surface area of from about 30 to 300 M 2 /g.
Claim 2
Dependent Claim
149 words
A free-flowing solid homogeneous detergent composition suitable for laundering soiled cotton, consisting essentially of: (a) from about 5 to 45 parts by weight of at least one fatty alcohol surfactant containing 6 to 18 carbon atoms, said alcohol or alcohols being the sole surfactant present; (b) from about 5 to 95 parts by weight of inorganic builder selected from the group consisting of sodium carbonate, sodium bicarbonate, sodium metasilicate, sodium sulfate, sodium chloride, sodium orthosilicate, and sodium sesquicarbonate; (c) from about 1 to 10 parts by weight of at least one of the following detergent adjuvants: anti-redeposition-compounds, heavy metal sequestering agents, optical bleach agents, whitening agents, corrosion inhibitors, tarnish inhibitors, and germicides, and (d) from about 5 to 45 parts by weight of finely divided, water-insoluble, chemically non-reactive inorganic absorbent, passing through a 365 mesh sieve and having surface area of from about 30 to 300 M 2 /g.
Claim 3
Dependent Claim
51 words
The fine-flowing, solid homogeneous detergent compositions of claim 1, wherein: (a) the fatty alcohol surfactant used is 1-decanol, (b) the builder is Na 2 CO 3 , and (c) free-flowing, finely divided chemically non-reactive inorganic absorbent is selected from the group consisting of alumina, silica, aluminum silicates and their fumed counterparts.
Claim 4
Dependent Claim
36 words
The fine-flowing solid homogeneous detergent composition of claim 1 wherein: (a) the fatty alcohol is isodecanol, (b) the builder is Na 2 CO 3 , and (c) the finely divided inorganic absorbent powder is alumina silicate.
Claim 5
Dependent Claim
43 words
The free-flowing, solid, homogeneous composition of claim 1 wherein: (a) the fatty alcohol is a C 10 -C 14 mixture, (b) the builder is Na 2 CO 3 , and (c) the finely divided, water-insoluble chemically non-reactive inorganic absorbent is a calcium silicate.
