FIELD: chemistry.
SUBSTANCE: invention relates to a method of reducing the formation of dust from a mass which is prone to dust formation. Method involves treating a mineral additive or any other dust-forming material with a block copolymer of glycerol and a hydroxy fatty acid to form a composition characterised by a reduced level of volatile dust.
EFFECT: invention is directed towards a method of reducing the release of dust from a mass prone to release dust.
