Screening of pH regulator triethanolamine in CGT matrix.

Triethanolamine (mL)	Appearance	Spreadability	Viscosity	Stability	pH
0.2	Brownish-yellow semi-solid	++	-	++	4.84
0.3	Brownish-yellow semi-solid	++	+	++	4.95
0.4	Brownish-yellow semi-solid	++	+	++	5.20
0.5	Brownish-yellow semi-solid	++	+	++	5.36
0.6	Brownish-yellow semi-solid	++	+	++	5.62
0.7	Brownish-yellow semi-solid	++	+	++	6.17
0.8	Brownish-yellow semi-solid	++	+	++	6.22
0.9	Brownish-yellow semi-solid	++	+	++	6.59
1	Brownish-yellow semi-solid	++	+	++	6.80

Note: “-” indicates absence (poor spreadability and application; the viscosity range is between 1 and 100 cP; stratification; no greasiness); “+” indicates moderate (spreadable, not easy to apply; the viscosity range is between 100 and 700 cP; stable; moderate greasiness); “++” indicates good (easy to spread and apply; the viscosity range is between 700 and 1100 cP; stable; slightly greasy).
