Abstract
Abstract A granular detergent composition having a high density comprises an organic surfactant, a water-soluble, crystalline, inorganic salt, another inorganic salt and/or an organic sequestering agent for a divalent metal and a granular, water-soluble, crystalline, alkaline, inorganic salt, said alkaline salt having been blended in the dry state with a base comprising the above other three components. Instead of the alkaline salt, a granular, wate-soluble, crystalline, inorganic salt having carried thereon an organic substance being capable of inhibiting hydration may be used.

Claim 1
Independent Claim
82 words
-1-A granular detergent composition, having a high density, which comprises: (a) 20 to 60 wt.% of an organic surfactant, (b) 2 to 15 wt.% of a water-soluble, crystalline, inorganic salt, (c) 25 to 78 wt.% of another inorganic salt and/or an organic sequestering agent for a divalent metal, and (d) 5 to 25 wt.% of a granular, water-soluble, crystalline, alkaline, inorganic salt, said (d) having been blended in the dry state with a base comprising the (a), the (b) and the (c).
Claim 2
Dependent Claim
74 words
-2-A composition as claimed in Claim 1, which comprises 20 to 60 wt.% of the (a), up to 15 wt.% of the (b), 25 to 80 wt.% of the (c) and (e) 5 wt.% or more of a granular, water-soluble, crystalline, inorganic salt having carried thereon an organic substance being capable of inhibiting hydration, said (e) having been blended in the dry state with a base comprising the (a), the (b) and the (c).
Claim 3
Dependent Claim
64 words
-3-A composition as claimed in Claim 1, which comprises 20 to 60 wt.% of the (a), 2 to 15 wt.% of the (b), and 25 to 78 wt.% of the (c), said salt (b) containing 2 wt.% or more, based on said (b), of an alkaline, inorganic salt, the total amount of the alkaline, inorganic salt(s) being 20 wt.% or more in the composition.
Claim 4
Dependent Claim
22 words
-4-A composition as claimed in Claim 1, in which said (a) organic surfactant contains 70 wt.% or more of an anionic surfactant.
Claim 5
Dependent Claim
30 words
-5-A composition as claimed in Claim 1, in which said (b) salt is selected from the group consisting of sodium carbonate, sodium sulfate, sodium tripolyphosphate, sodium pyrophosphate and sodium orthophosphate.
Claim 6
Dependent Claim
22 words
-6-A composition as claimed in Claim 1, in which said (d) salt has an average particle size of 100 to 1000 microns.
Claim 7
Dependent Claim
22 words
-7-A composition as claimed in Claim 2, in which said (e) is particles of a water-soluble, crystalline, inorganic salt having carried thereon
Claim 8
Dependent Claim
71 words
-8-A composition as claimed in Claim 2, in which said salt (e) is particles of an inorganic substance having carried thereon a nonionic surfactant and having been coated with polyethylene glycol. an organic substance having a melting point of 40°c or lower and being capable of inhibiting hydration, said particles having been coated with an organic substance being capabel of inhibiting hydration and having a melting point of 40°c or higher.
Claim 9
Dependent Claim
16 words
