Additive composition useful for controlling the foam properties in the production of flexible polyurethane foams containing polyols based on renewable raw materials

A process for production of polyurethane foams comprising reacting one or more polyol components with one or more isocyanate components in the presence of an additive composition, said additive composition comprising:

• an ionic surfactant selected from component a), component b) and a combination of component a) and component b), wherein component a) comprises at least one ionic surfactant A of formula (I)
• A−M+ (I)
• where A−=anion selected from alkyl and aryl sulphates, polyether sulphates and sulphonates, sulphonates, alkyl and aryl sulphonates, alkyl and aryl carboxylates, saccharinates and polyether phosphates, and M″ is a cation, and component b) comprises at least one ionic surfactant B selected from a quaternized ammonium compound;
• and
• at least one of component c) and component d) wherein component c) comprises at least one tertiary amine compound which has a molar mass of at least 150 g/mol, and component d) comprises at least one oxazasilinane.
