Invite nature into your oil painting studio. Green For Oil represents a safe, greener alternative to traditional solvents! Traditional organic solvents are highly effective, but concerns have been raised regarding their volatility and petroleum-based origins. Therefore, Sennelier has developed eco-friendly solvents with their new GREEN FOR OIL range. The ingredients are sourced from renewable raw materials, derived from plant or mineral based raw materials. They respect sanitary and environmental standards and importantly their main features are just as effective as traditional solvent.
