Our mercaptans
Mercaptans (also called thiols) consist of a sulphur atom that is bonded to an alkane (saturated hydrocarbon molecule). The general chemical formula for mercaptan is R-SH with the R standing for the hydrocarbon residue.
Used in cosmetics
A popular field of application is the cosmetics industry where the substances are used as reducing agents for wavy-hair products (chemical perms) or for depilation purposes.
Used in the plastics industry
Another large area of application is the production of plastics where mercaptans are used as cross-linkers or chain extenders. They can contribute to the cross-linking of polymer chains and, by doing so, improve the mechanical properties of plastics.

2-Mercaptoethanole
2-Mercaptoethanol is used in the pharmaceutical, cosmetics, agrochemical, dye, textile and plastics industries as well as in mineral oil processing (oilfield chemicals). It is suitable for the production of rubber materials and plasticisers and as a tin stabiliser in the PVC industry.
In polymer modification, 2-Mercaptoethanol is used as a chain transfer reagent, for the modification of end groups and as a cross-linking agent.
In biochemistry, it is used as an enzyme modulator and for the purification and stabilisation of enzymes, DNA and RNA.

n-Dodecylmercaptane
Lauryl mercaptan is used in the chemical, pharmaceutical and agrochemical industries.
As a primary mercaptan, many standard reactions can take place with NDM, such as the addition of double bonds and reactions with aldehydes and ketones to form thioacetals and thioketals, or the formation of metal mercaptide salts.
NDM is used in the production of antioxidants for polyolefins and for the production of hydrophobic or mixed monolayers.
It is also used as a polymerisation inhibitor in various adhesives and as a very effective chain transfer agent for radical polymerisation.

Tertiary Dodecylmercaptane (TDM)
tert-dodecanethiol is used as a chemical intermediate in various syntheses.
It is used in the production of high-pressure additives, fragrances, non-ionic surfactants and fungicides.
As a synthesis chemical, TDM is mainly used as a molecular weight regulator in the polymerisation of butadiene- and styrene-based processes such as butadiene latex and synthetic rubbers, polystyrenes and styrene lacquers.
