Application

Substitution of a hydrocarbon-based anti-adherent

Abstract

A highly flammable anti-adherent compound containing toxic solvents used in welding was substituted by a water-based product. The eliminated product contained dichloromethane which posed serious health hazards since it is a suspected carcinogen and endocrine disruptor. The alternative product contains synthetic oils and water-based anti-corrosion additives.

Substituted substances

Dichloromethane

CAS No. 75-09-2 EC No. 200-838-9 Index No. 602-004-00-3

Hazard Assessment

Substance to be substituted: The substituted product contained dichloromethane. It is a Substance of very high concern and is included on the REACH restriction list, according to Article 73 of Regulation (EG) No. 1907/2006. (REACH Regulation). Alternative substance: The alternative product does not contain any substance from the SDSC list and it does not include any component classified as hazardous.

Description of Substitution

The use of anti-adherent sprays containing toxic chemicals is widespread in industrial welding. Hazardous hydrocarbon solvents which are highly flammable and hazardous to human health are commonly used. This substitution experience was carried out in a company specialised in the manufacture of storing systems located in Vizcaya (Spain). Company managers decided to substitute the solvent-based anti-adherent compound by a water-based product. The alternative product contains synthetic oils and water-based anti-corrosion additives. Advantages - Increased performance due to the bigger amount of active product contained in aerosols - Reduction of hazardous wastes, which also implies cost savings. - The product is easily cleaned with water.

Case/substitution evaluation

Substitution was successful since it eliminated a possible carcinogen (H351). The alternative product does not contain any components classified as hazardous. This case proves the existence of feasible safer alternatives for the extensive use of solvents in this given branch of industry.
