[0212] According to the phase inversion temperature method (PIT method), the following emulsion A1 was prepared:
[0213] making process:
[0214] 1. Heat phase A in a water bath with Rayneri stirring (400 rpm). A liquid white emulsion was obtained which became translucent (passing through the microemulsion phase) at about 68°C and thickened above this temperature.
[0215] 2. Once the emulsion has thickened, remove the water bath: allow the emulsion to cool with continuous stirring.
[0216] 3. Introduce Carbopol at about 50°C.
[0217] 4. On cooling to room temperature, introduce ethanol and monoethanolamine and readjust for evaporation loss (<5%).
[0218] This gave a translucent gelled emulsion with a droplet size of <1 μm (viscosity = 72 DUM4 (measured by rheomat), pH 11.5).
[0219]
[0220] In use, emulsion A1 is mixed by weight with an oxidized aqueous composition (B) com...
