FIELD: chemistry.
SUBSTANCE: invention relates to composition for decomposition of gelled liquids used on underground formations during hydraulic fracturing. The composition for decomposition of cross-linked guar gum based gel contains an organic peroxide and a peroxide activator and a carboxylic ester with 2-8 carbon atoms, with the following ratio of components, wt %: organic peroxide 51-70; ester 30-49 and content of peroxide activator of 2-14% of the mass of guar gum.
EFFECT: providing full decomposition of the gel without forming a flocculent precipitate.
