An organic acid having at least two carboxylic acid groups, no tertiary amino groups and a pK a of up to 3.1 is added to an HCFC blowing agent or to a composition, preferably an isocyanate-reactive composition, in which an HCFC blowing agent is present to reduce decomposition of the HCFC blowing agent. The resultant compositions are useful in the production of polyisocyanurate, polyurethane and/or polyurea foams.
