The present invention provides a biodegradable cleaning composition that includes a surfactant component including an ethoxylated 2-propyl heptanol, a chelating component including a tri-sodium salt of methylglycinediacetic acid and an emulsifier component including an ethoxylated hexanol having the formula CHO(CHCHO)H. The ethoxylated 2-propyl heptanol has the formula CHCH(CH)CHO(CHO)H, wherein p is a number of from 3 to 6. The composition also includes water and an acid component to establish a pH of the composition at less than 2. The composition is substantially free of solvents thereby reducing emission of volatile organic compounds and reducing potential environmental pollution and health hazards. The composition is also effective in removing rust, lime soap, and metal salts of fatty acids from hard surfaces including metal, vinyl, and fiberglass.

Biodegradable cleaning composition

The present invention relates to an aqueous based, solvent free degreaser composition, comprising a blend of two nonionic surfactants selected from, alcohol alkoxylate with a fatty alcohol moiety, alkoxylated fatty alcohol, fatty alcohol having oxyethylate moieties, polyoxyalkylene block copolymers, and alkyl phenol alkoxylate.

Aqueous based solvent free cleaner compositions containing two nonionic surfactants

Cleaning formulations and methods are provided by which solid deposition is inhibited on hydrophobic hard surfaces typically encountered in bathroom and outdoor environments without detrimentally affecting the appearance of such surfaces. The formulations most preferably include an aqueous mixture of an organically solvated nonionic copolymer, a polyacrylic acid homopolymer and a nonionic surfactant. Optionally, a hydrotrope may also be present in the formulation. Most preferably, the formulations of this invention have a pH between about 4.0 to about 7.0, most preferably around neutral (i.e., about 7.0). In specific embodiments, the formulations include an aqueous mixture of (a) a graft copolymer of polyalkylene oxide with vinyl ester, the graft copolymer having a molecular weight within the range of about 5,000 to 50,000, (b) at least one polycarboxylate selected from the group consisting of acrylic acid/maleic acid copolymers, having a molecular weight within the range of about 1,000 to 100,000 and polyacrylic acid having a molecular weight of from about 1,000 to about 100,000, (c) at least one nonionic surfactant selected from the group consisting of alcohol alkoxylates, alcohol block alkoxylates, and polyoxyethylene/polyoxypropylene triblock surfactants, and (d) one or more water soluble organic solvents.

Anti-spotting and anti-filming hard surface cleaning formulations and methods

The present invention relates to an aqueous based, solvent free degreaser composition, comprising a blend of two nonionic surfactants selected from, alcohol alkoxylate with a fatty alcohol moiety alkoxlyate, fatty alkoxlyated alcohol, fatty alcohol having oxyethylate moieties, polyoxyalkylene block copolymers, and alkyl phenol alkoxylate.

Aqueous based solvent free cleaning compositions containing alcohol

A machine dishwashing composition is provided wherein two specifically defined nonionic surfactants are utilized which in combination have been shown through empirical research to surprisingly yield improved results. One of the nonionic surfactants is an alcohol alkoxylate (as defined) and the other nonionic surfactant is a block copolymer of ethylene oxide and propylene oxide (as defined). The use temperature for efficient cleaning while using the composition extends over a broad range up to at least 140.degree. F. in the absence of deleterious foaming even in the presence of protein soil (e.g., egg and/or milk soil).

An aqueous rinse-aid composition for kitchen utensils is provided wherein an anionic hydrotrope and a blend of two specifically defined nonionic surfactants are utilized which has been shown through empirical research to surprisingly yield improved results. One of the nonionic surfactants is an alcohol alkoxylate (as defined) and the other nonionic surfactant is a block copolymer of ethylene oxide and propylene oxide (as defined). The composition is suitable for use at a temperature of up to at least 180.degree. F. in the absence of excessive foaming, spotting and film formation. The components of the composition exhibit good compatibility during storage even if elevated temperatures are experienced thereby maintaining reliable performance upon usage. Rapid high velocity rinsing at a high temperature is made possible in the absence of deleterious foam generation to yield dishes and tableware that can be readily dried without the need for the time consuming hand removal of deleterious spots and/or film.
