[0246] Preparation of gel network premix
[0247] To prepare the gel network premix of Table 1, the water was heated to about 74°C, and the fatty alcohol and gel network surfactant were added to it in the amounts shown in Table 1. After incorporation, the mixture is passed through a mill and a heat exchanger, where it is cooled to about 32°C. As a result of this cooling step, fatty alcohol, gel network surfactant, and water form a crystalline gel network.
