Classification: CPC C | IPC C

Claim 1:
2. The process according to claim 1, in which, in 1), the aqueous silicone emulsion E1 is prepared by mixing:
a first “pre-emulsion” comprising the organopolysiloxanes A and B, the emulsifying agent D, the crosslinking inhibitor F, water, optionally at least one pH-fixing agent G chosen so as to maintain the pH of the emulsion E1 between 5 and 9 and optionally at least one formulation additive H,
a catalysing second “pre-emulsion” comprising the polyaddition catalyst C, the emulsifying agent D, the organopolysiloxane, water, optionally at least one pH-fixing agent G chosen so as to maintain the pH of the emulsion E1 between 5 and 9 and optionally at least one formulation additive H, and
a third “pre-emulsion” comprising the additive X, the emulsifying agent D, water, optionally at least one pH-fixing agent G chosen so as to maintain the pH of the emulsion E1 between 5 and 9 and optionally at least one formulation additive H.
