Uses and applications

What the substance is used for, by industry and function

Ethyl methacrylate is used to make polymers, which in turn are used for building, automotive, aerospace, and furniture industries.

Used as a comonomer in acrylic polymers for surface coating resins, acrylic emulsion polymers for polishes, etc, comonomer in denture-base material, and used as a chemical intermediate.

Butyl or ethyl methacrylate copolymers with hydrophilic hydroxyethyl methacrylate & relatively large amounts of the cross-linking agent triethylene glycol dimethacrylate produces hard hydrophilic polymers that can be machined into hard contact lens with wettable surfaces.

Polymers, chemical intermediates.

Industrial uses: Filler, Adhesion/cohesion promoter, Monomers.

Use classes: Cosmetics.

Cosmetic ingredient, INCI name ETHYL METHACRYLATE(viscosity controlling)

Functional uses

  • Flavouring and nutrient
  • Fragrance
  • Viscosity modifier

Cosmetic functions

  • Viscosity controlling

How it is made

Reaction of methacrylic acid or methyl methacrylate with ethyl alcohol in the presence of a mineral acid.

Made by a reaction between ethanol and methyl methacrylate (transesterification). The catalyst is sodium alcoolate. Extraction by methanol.

Commercial production of ... methacrylates, which began in ... 1933 ... from acetone cyanohydrin (ACN) involved conversion of acetone cyanohydrin to alpha-hydroxybutyrate ester followed by dehydration to the methacrylate with phosphorus pentachloride (PCl5). In 1934, a process was patented for converting acetone cyanohydrin to methacrylamide sulfate which is hydrolyzed & esterfied to the methacrylate ester, this process forms the basis for all contemporary commercial methacrylate production. (Methacrylates)
