The Triethanolamine is used primarily as an emulsifier and surfactant. It also serves as a PH balancer in many different cosmetic products - ranging from cleansing creams and milks, skin lotions, eye gels, moisturizers, shampoos, shaving foams etc. TEA is a fairly strong base: a 1% solution has a PH of approximately 10, whereas the PH of skin is below PH 7. Cleansing milk/cream emulsions based on TEA are particularly good at removing make up.

Physical properties about Triethanolamine are: (1)ACD/BCF (pH 5.5): 1; (2)ACD/BCF (pH 7.4): 1; (3)ACD/KOC (pH 5.5): 1; (4)ACD/KOC (pH 7.4): 1.57; (5)#H bond acceptors: 4; (6)#H bond donors: 3; (7)#Freely Rotating Bonds: 9; (8)Polar Surface Area: 63.93 Ų; (9)Index of Refraction: 1.511; (10)Molar Refractivity: 38.17 cm³; (11)Molar Volume: 127.3 cm³; (12)Polarizability: 15.13×10^-24cm³; (13)Surface Tension: 54.9 dyne/cm; (14) Density: 1.171 g/cm³; (15)Flash Point: 185 °C; (16)Enthalpy of Vaporization: 67.02 kJ/mol; (17)Boiling Point: 335.4 °C at 760 mmHg; (18)Vapour Pressure: 8.38E-06 mmHg at 25°C.

Preparation: this chemical is produced from the reaction of ethylene oxide with aqueous ammonia, also produced are ethanolamine and diethanolamine. The ratio of the products can be controlled by changing the stoichiometry of the reactants.

Uses of Triethanolamine: it can be used to produce 6,7-dimethyl-indole at temperature of 180 °C. It will need reagent SnCl₂*2H₂O and solvent dioxane with reaction time of 20 hours. The yield is about 99%.

When you are using this chemical, please be cautious about it as the following:
This chemical is irritating to eyes, respiratory system and skin. When you are using it, wear suitable protective clothing and eye/face protection. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
