Abstract

Cleaning products of the hard surfaces of the present invention are products based on 4 ... 12% surface agents and 80 ... 90% specific systems of conditioning, of which 60% is calcium carbonate - waste from the manufacture of caustic soda. These are pulp or powder products and are for the cleaning of hard surfaces: faience, sandstone, porcelain, email, stainless steel, etc. Products conform of the invention provides good cleaning of the hard surfaces, having at the same time the property to rinse and dry slightly, without leaving, after drying, opaque stains on washed surfaces and being well tolerated by the skin.

Description

The present invention relates to a range of products for cleaning hard surfaces, in which calcium carbonate - waste from the manufacture of caustic soda, products intended for cleaning hard surfaces: tiles, faience, porcelain, enamel, stainless steel, is used. These . products formulated based on surface agents and specific conditioning agents, most of which are calcium carbonate, are presented as products in the form of powder or t, pastes, with different consistencies, depending on the intended use and packaging.

From the patent literature, there are known products for cleaning hard surfaces, containing abrasive materials, which are mentioned in the patents: US 4,842,757 / 1989 (CI Cil D7 / 54); EP 329.209 / 1989 (CI Cyl D3 / 43); EP 334,566 / 1989 (CI CI 1 D17 / 00); EP 335.471 / 1989 (CI Cyl D3 / 43).

Detergent compositions contain, along with calcium carbonate (caustic soda residue) and / or other materials with abrasive properties and significant amounts of alkaline carbonates: sodium sesquicarbonate or sodium carbonate / bicarbonate. The removal of greasy dirt is facilitated by the presence, in compositions, of alkali silicates and polyols, which also have the role of hydrotropes, ensuring a good homogeneity of the products and increased solubility in water, rinsing easily, leaving no trace .

The object of the present invention is to establish the combination of surface agents and organic and inorganic salts, conditioning, together with calcium carbonate, to ensure a good cleaning of hard surfaces, while giving the product the quality to rinse and dry easily and not to leave opaque spots on the surfaces after drying.

The problem solved by the invention is that of making compositions which, having as main component calcium carbonate, can ensure a good cleaning of hard surfaces, having, at the same time, the property to rinse and dry easily, without leaving spots. Opaque on surfaces and being well tolerated by the skin.
