Enzymes are organic macromolecules of proteic nature, present in all living organisms, which

enormously increase the velocity of the biochemical reactions of a substratum conversion. They have a high selectivity degree as they accelerate specific chemical reactions, without the formation of by-products, functioning in aqueous solutions diluted in mild temperature and pH conditions.

The Enzymes used in restoration (painting cleaning) are all hydrolases, which catalyse the

breakdown of organic macromolecules, by adding water.

According to the organic nature of the substratum to be cleaned, the hydrolytic Enzymes are divided in:

• Amylases - they degrade polysaccharides

• Lipases - they degrade fat materials

• Proteases - they degrade proteic materials

Thanks to the efficacy verified after long experiences in the field and the complete non-toxicity

of these products, in some restoration workshops this new technique has passed from a

curiosity to a cleaning operation supplemented with the traditional solvent technique.

Enzyme preparations are neutral (pH  range = 6 - 8) and besides have an activity

plateau between 20 and 40°C (their activity decreases slowly under 20°C to stop completely at 10°C). This range covers the values that one normally finds in a workshop and often finds again on the outdoor.

The use of Enzymes for the removal of polymeric substances present in the pictorial layer is a valid alternative to the use of organic solvents.
