Trimethylolpropane triacrylate (TMPTA) is a trifunctional acrylate ester monomer derived from trimethylolpropane, used in the manufacture of plastics, adhesives, acrylic glue, anaerobic sealants, and ink. It is useful for its low volatility and fast cure response.
TMP is mainly consumed as a precursor to alkyd resins.Otherwise, acrylated and alkoxylated TMP's are used as multifunctional monomers to produce various coatings, Ethoxylated and propoxylated TMP, derived condensation of from TMP and the epoxides, are used for production of flexible polyurethanes.

It is a derivative of pentaerythritol [2] One of the key uses of the material is in polymeric synthesis where it can form micelles and block copolymers. [ 3 ] [ 4 ] The molecule's acrylate group functionality enables the molecule to do the Michael reaction with amines .
Fatty alcohols are relatively benign materials, with LD 50 (oral, rat) ranging from 3.1–4 g/kg for hexanol to 6–8 g/kg for octadecanol. [1] For a 50 kg person, these values translate to more than 100 g. Tests of acute and repeated exposures have revealed a low level of toxicity from inhalation, oral or dermal exposure of fatty alcohols.
In December 2012, the European Chemicals Agency (ECHA) included the substance group “4-(1,1,3,3-tetramethylbutyl)phenol, ethoxylated” – which includes Triton X-100 – in the Candidate List of substances of very high concern [9] of the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) Regulation which addresses ...
Nonylphenol is also often used an intermediate in the manufacture of the non-ionic surfactants nonylphenol ethoxylates, which are used in detergents, paints, pesticides, personal care products, and plastics. Nonylphenol and nonylphenol ethoxylates are only used as components of household detergents outside of Europe. [2]
Narrow-range ethoxylates (NREs) in chemistry are fatty alcohol polyglycol ethers with a narrow homolog distribution and are known nonionic surfactants.They can be produced industrially, for example, by the addition of ethylene oxide onto fatty alcohols in the presence of suitable catalysts (layer compounds which have been calcined or hydrophobized with fatty acids).
