Hexahydro-1,3,5-Tris(hydroxyethyl)-S-Triazine is a triazine derivative contained in cutting fluids. It is a formaldehyde releaser. Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine is an amine and an alcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Hexahydro-l,3,5-tris-(2-hydroxyethyl)triazin is used in organic synthesis; as a bactericide in cooling fluids and various cosmetic products; formaldehyde liberator. Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine is probably combustible. It is a triazine derivative contained as a bio cide in cutting fluids. It is a formaldehyde releaser. Dermatitis, delayed-type allergic conjunctivitis, and asthma were described.
