For the remaining 11 chemicals (boric acid, iron [III] phosphate dihydrate, potassium hydroxide,
triethanolamine, zinc chloride, trisodium phosphate dodecahydrate, neutral calcium alkylaryl sulfonate, neodecanoic acid, ferric chloride, hydroxyethyl cellulose, and sodium palmitate), the increase in moisture level corresponded in an increase in TAN when the initial chemical concentration changed from 0.1% to 1.0%.

Sample Prepared with
Triethanolamine. For preparation of
triethanolamine sample, 18 ml ethanol, 2 ml distilled water, and TEA were added to chemical mixture in a glove box and dissolved for 30 minutes with magnetic stirring before keeping in ultrasonic bath for 5 minutes.

Of the other six chemicals (with TAN[less than or equal to] 0.5 at low concentration with both aging temperatures), Potassium Fluoride, Sulfamic Acid, Sodium Nitrite and
Triethanolamine Borate had TAN between 0.5 and 1.0 at the high concentration with both aging temperatures while Potassium Hydrogen Fluoride and Hydroxyethyl Cellulose had TAN greater than 1.0 at the high aging temperature.
One male patient who had positive patch test from butylated hydroxyanisole (antioxidant in cosmetics),
triethanolamine (surface-active agent in soaps, shampoos), and gallate mix was using fairness creams, antiacne (herbal) cream, and soaps but elicited no positive reaction from these products.

The
triethanolamine (TEA) was poured into each solution with molar ratio 1:3 of excess TEA and continued stirring for 20 min.
Urea, formaldehyde aqueous solution (37 wt %), and distilled water were mixed and the pH was adjusted to 8-9 with
triethanolamine, and then the mixture was stirred at 70[degrees] C with a stirring rate of 450 rpm for 60 min to prepare UF precursor solution.
Other ingredients to avoid for many reasons include diethanolamine (DEA),
triethanolamine (TEA), 1,4-dioxane, ethoxylated alcohols, butyl cellosolve (aka ethylene glycol monobutyl ether), and p-nonylphenol.
Discs are then placed on filter paper to allow the acetone to evaporate and thus leaving a fine coating of
triethanolamine (TEA).
