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

A composition comprising a polyurethane foam having incorporated therein an additive composition comprising:

• (i) at least one quaternized ammonium compound that functions as an ionic surfactant;
• (ii) at least one tertiary amine compound having a molar mass of at least 150 g/mol and is a compound of formula (V)
• where
• R4 is selected from saturated or unsaturated hydrocarbon moieties having 5 to 30 carbon atoms,
• R5 is selected from divalent alkyl moieties having 2 or 3 carbon atoms,
• R6 is selected from alike or different alkyl moieties having 1 to 3 carbon atoms;
• and
• (iii) at least one oxazasilinane;
• and
• wherein the mass ratio of the total mass of all of the at least one tertiary amine compounds having a molar mass of least 150 g/mol and of the formula (V) to the total mass of all oxazasilinanes is in a range from 200:1 to 5:1.
