Abstract
Official abstract text for this publication.
A method for wetting and/or conditioning soil comprises applying a soil treatment composition containing hydrolysed protein to the soil. The soil treatment composition preferably contains a surfactant selected from ethylene oxide-propylene oxide (EO/PO) block copolymer and/or an alkyl polyglycoside. The soil treatment composition may also contain an additional alkoxylate surfactant.
First claim
Opening claim text (preview).
The invention claimed is: 1. A soil treatment composition for wetting and/or conditioning soil comprising: 1,000 to 30,000 ppm of a hydrolysed protein, where the hydrolysed protein comprises an average of 1.5 to 200 amino acids, an ethylene oxide-propylene oxide (EO/PO) block copolymer and/or an alkyl polyglycoside as a surfactant, at least one additional alkoxylate surfactant and water. 2. The composition according to claim 1 wherein the ethylene oxide-propylene oxide (EO/PO) block copolymer has the formula (EO) x −(PO) y −(EO) z wherein x and z are each independently 1 to 10; and y is 10 to 50. 3. The composition according to claim 2 wherein x and z are 5.5 and y is 33. 4. The composition according to claim 1 wherein the at least one additional alkoxylate surfactant is a fatty acid alkoxylate and/or an alkoxylated glyceride. 5. The composition according to claim 4 wherein the alkoxylated glyceride is PEG-60 triglyceride and/or PEG-6 capric/caprylic glyceride. 6. The composition according to claim 4 wherein the fatty acid alkoxylate is PEG-9 laurate. 7. The composition according to claim 1 wherein the soil treatment composition comprises 3,000 to 30,000 ppm of the ethylene oxide-propylene oxide (EO/PO) oxide block copolymer or alkyl polyglycoside. 8. The composition according to claim 1 wherein said the soil treatment composition comprises 3,000 to 30,000 ppm of the at least one additional alkoxylate surfactant. 9. The composition according to claim 1 wherein the ratio by weight of the total surfactant to the hydrolysed protein is 0.6 to 1.8:1. 10. A soil treatment composition concentrate comprising: (a) (i) 6 to 13 wt.% of a hydrolysed protein, (ii) 2 to 10 wt. of (EO/PO) block copolymer, (iii) 2 to 10 wt.% of ethoxylated glyceride esters, and (iv) 65 to 90 wt.% of water, where the hydrolysed protein comprises an average of 1.5 to 200 amino acids; or (b) (i) 1 to 4 wt.%, of a hydrolysed protein, (ii) 5 to 18 wt.% of (EO/PO) block copolymer, (iii) 5 to 18 wt.% of fatty acid ethoxylate, and (iv) 45 to 85 wt.% of water, where the hydrolysed protein comprises an average of 1.5 to 200 amino acids.
