CA 2193825

Stable, silicate-free, soft metal safe, alkaline cleaners are provided. The cleaners comprise calcium ions and surfactants containing hydroxyl and/or carboxylic acid groups or a combination thereof, wherein the total of the two functionalities in each surfactant is greater than or equal to 2, and alpha-hydroxy carboxylic acids. It has been surprisingly discovered that alpha-hydroxy carboxylic acids such as tartaric acid, are capable of keeping calcium ions in an alkali solution. The cleaners may also comprise non-ionic surfactants to provide wetting, detergency, and foamability where required, anionic surfactants as viscosity enhancers in the case of high retention cleaners, and solvents such as alcohols, glycol ethers, or hydrotropes to enhance solubility of the system. The alkaline cleaners are safe to use on soft metal surfaces and equipment commonly found in many industries, without the presence of silicate which is normally used as a corrosion inhibitor.

Produits de nettoyage alcalins, stables, exempts de silicates et n'attaquant pas les métaux tendres incluant des ions calcium et des tensio-actifs à groupes acides hydroxyles et/ou carboxyliques (ou leur mélange) où le total des deux fonctions de chacun des tensioactifs est supérieur ou égal à 2, et des acides alpha-hydroxycarboxyliques. On a été surpris de découvrir que qui les acides alpha-hydroxycarboxyliques tels que l'acide tartrique peuvent retenir les ions calcium dans une solution alcaline. Lesdits produits de nettoyage peuvent également contenir si nécessaire des tensio-actifs non ioniques à pouvoir mouillant, détergent et moussant et des tensio-actifs ioniques renforçateurs de viscosité pour les produits à forte rétention, ainsi que des solvants tels que des alcools, des esthers glycols ou des hydrotropes améliorant la solubilité du système. Ces produits de nettoyage alcalins n'attaquent pas la surface des métaux tendres ni les équipements communs à nombre d'industries sans toutefois contenir de silicates servant usuellement d'inhibiteurs de corrosion.
