Abstract
Improved multi-purpose metal cleaning compositions are provided comprised of 5 to 40 parts by weight ethoxylated aliphatic alcohol or ethoxylated alkylphenol, 4 to 20 parts by weight alkanolamine salt of a fatty acid, 2 to 15 parts by weight boramide, 2 to 15 parts by weight alcohol, glycol or ether glycol, 0.05 to 2.5 parts by weight antifoam agent, and 5 to 98 parts by weight water. In addition to being highly effective cleaners for the removal of grease, oil, dirt, scale and metal fines, the compositions of this invention also provide a non-sticky and non-greasy corrosion-resistant protective barrier on the surface of the metal.
Claims8
A multi-purpose metal cleaning composition comprising:
- (a) 5 to 40 parts by weight ethoxylated aliphatic alcohol or ethoxylated alkylphenol;
- (b) 4 to 20 parts by weight alkanolamine salt of a fatty acid;
- (c) 2 to 15 parts by weight boramide obtained by the reaction of boric acid or its analogs with a molar excess of alkanolamine selected from the group consisting of diethanolamine, diisopropanolamine and triethanolamine at a temperature of about 130.degree. C. or above;
- (d) 2 to 15 parts by weight alcohol, glycol or ether glycol;
- (e) 0.05 to 2.5 parts by weight antifoam agent;
- and
- (f) 5 to 98 parts by weight water.
A metal cleaning composition comprised of 10 to 30 parts by weight ethoxylated (9 E.O.) nonyl phenol, 6 to 16 parts by weight triethanolamine salt of oleic acid, 3 to 10 parts by weight triethanolamine borate obtained by reacting boric acid with a molar excess of triethanolamine at a temperature of 130.degree. C. or above, 3 to 10 parts by weight ethylene glycol monobutyl ether, 0.1 to 1.0 parts by weight silicone antifoam and 33 to 96 parts by weight water.
