Two-in-one dishwash detergent
The present invention relates to a concentrate composition and its use solution for disinfecting and cleaning hard surfaces. The concentrate composition and the use solution comprise an alkylamidopropyl betaine, amphoteric surfactants and biocidal active substances at a moderately alkaline pH. The inventive composition is suitable for disinfecting and cleaning hard surfaces, in particular hard surfaces in contact with food products, such as surfaces found in food processing, manual warewashing, food services and health care industries. Methods of applying and making such concentrate composition and use solution are also provided.
1 . A concentrate composition for disinfecting and cleaning hard surfaces comprising:
a) a biocidal active substance comprising bis(3-aminopropyl)alkylamine, wherein the alkyl group consists of 6 to 18 carbon atoms;
b) at least 20 wt. % of two or more amphoteric surfactants, wherein the two or more amphoteric surfactants comprise an amine oxide and an alkylamidopropyl betaine, wherein the alkyl group consists of 6 to 19 carbon atoms;
c) a buffer system for adjusting the pH of said concentrate composition to 8 to 11;
d) water; and
wherein the composition is free of quaternary ammonium compounds, enzymes, hydrotropes, and organic solvents.
2 . The concentrate composition according to claim 1 , wherein the concentrate composition has a pH of 9 to 10.5.
3 . The concentrate composition according to claim 1 , wherein the composition is further substantially free of phosphorous-containing compounds.
4 . The concentrate composition according to claim 1 , wherein the composition comprises:
a) 0.5 to 10 wt. % the biocidal active substance;
b) 1 to 30 wt. % of the amine oxide, and 1 to 15 wt. % of the alkylamidopropyl betaine;
c) 1 to 30 wt. % buffer system; and
d) 20 to 80 wt. % water.
5 . The concentrate composition according to claim 1 , wherein the composition comprises:
a) 2 to 5 wt. % the biocidal active substance;
b) 20 to 45 wt. % of the two or more amphoteric surfactants;
c) 5 to 15 wt. % buffer system; and
d) 30 to 70 wt. % water.
6 . The concentrate composition according to claim 1 , wherein the composition further comprises one or more of soil release polymers, polymeric dispersants, polysaccharides, abrasives, tarnish inhibitors, builders, dyes, buffers, perfumes, opacifiers, thickeners, processing aids, suds boosters, brighteners, anti-corrosive aids, stabilizers, antioxidants, or chelants.
7 . The concentrate composition according to claim 1 , wherein the bis(3-aminopropyl)alkylamine comprises one or more of bis(3-aminopropyl) octylamine, bis(3-aminopropyl) decylamine, bis(3-aminopropyl) dodecylamine, bis(3-aminopropyl) quatrodecylamine, bis(3-aminopropyl) hexadecylamine, or bis(3-aminopropyl) octadecylamine.
8 . The concentrate composition according to claim 1 , wherein the buffer system is a citrate buffer system.
9 . The concentrate composition according to claim 1 , wherein the composition achieves a ≥5.0 log 10 reduction of Staphylococcus aureus within 5 minutes at 20° C. at a 1.0 wt. % use-solution according to EN 13697 (2015)+A1 (2019).
10 . The concentrate composition according to claim 1 , wherein the composition further comprises a non-ionic surfactant.
11 . The concentrate composition according to claim 1 , wherein the alkylamidopropyl betaine comprises cocamidopropyl betaine.
12 . The concentrate composition according to claim 1 , wherein the composition further comprises a chelating agent that comprises glutamic acid-N,N-diacetic acid.
13 . A method for disinfecting and cleaning hard surfaces, the method comprising:
applying to the hard surface a concentrate composition according to claim 1 .
14 . The method according to claim 13 , wherein a disinfection efficacy according to one or more of the European standard test methods EN 1650 (2019), EN 1276 (2019) and EN 13697 (2015) in combination with A1 (2019) is obtained.
15 . The method according to claim 13 , wherein the hard surface is one of ware, pots, pans, floors, walls, tiles, or countertops.
16 . The method according to claim 13 , wherein the concentrate composition is applied by soaking, spraying, wiping or foaming.
