Weigh together the "TEGAMINE" S-13, phosphoric acid and water. Heat with agitation. After the "TEGAMINE" S-13 has melted, been neutralized by the phosphoric acid and gone into solution add the "TEGOSEPT" M, "WSP" X-250 and "TEGIN" 55-G. Hold the temperature at about 75'C (contining the agitation) until the "TEGIN" 55-G has melted and been completely dispersed in the system. Cool with agitation to about 35'C. Pearlescence will develop on standing.
