Abstract
A dishwasher composition includes at least one strong chelant, at least one weak chelant, at least one surfactant, and at least one enzyme. The dishwasher composition can be a liquid or a gel and has a pH of from 7.0 to 9.5 and may contain less than 1 wt. % silicates based on the total weight of the dishwasher composition. Methods of washing articles include preparing a wash solution that includes water and the dishwasher composition, and contacting at least one article with the washing solution during at least a portion of a wash cycle of a commercially-available dishwasher.
Claims20
A dishwasher composition comprising:
- at least one strong chelant, at least one weak chelant, at least one surfactant, at least one enzyme, and one or more enzyme stabilizing additives comprising a tripeptide inhibitor(s), 4-formyl, phenyl boronic acid, or both;
- wherein the dishwasher composition is a liquid or a gel having a pH of from 7.0 to 9.5, and the dishwasher composition includes less than 0.5 wt. % silicates based on the total weight of the dishwasher composition.
A method of washing articles, the method comprising:
- forming a washing solution in a washing machine, the washing solution comprising water and a dishwasher composition, the dishwasher composition comprising:
- at least one strong chelant, at least one weak chelant, a structural constituent, at least one surfactant, at least one enzyme comprising one or a plurality of hydrolase enzymes, and one or more enzyme stabilizing additives comprising a tripeptide inhibitor(s), 4-formyl, phenyl boronic acid, or both;
- wherein the dishwasher composition is a liquid or a gel having a pH of from 7.0 to 9.5, and the dishwasher composition includes less than 0.5 wt. % silicates based on the total weight of the dishwasher composition;
- and
- contacting at least one article with the washing solution during at least a portion of a wash cycle of a commercially-available dishwasher.
A dishwasher composition comprising:
- at least one strong chelant, at least one weak chelant, at least one surfactant, at least one enzyme, and at least one detersive polymer comprising a structure with carboxymethyl inulin;
- wherein the dishwasher composition is a liquid or a gel having a pH of from 7.0 to 9.5, and the dishwasher composition includes less than 0.5 wt. % silicates based on the total weight of the dishwasher composition.
