Many compounds have been formulated a formaldehyde-releasers. [2]Quaternium-15 (Dowicil 200; Dowicil 75; Dowicil 100; Dowco 184; Dowicide Q). It was used in low concentrations in cosmetics but has been banned in the EU since 2017 and a bill is under consideration in the US.
1,6-Hexanediol diglycidyl ether is an organic chemical in the glycidyl ether family. It is an aliphatic compound that is a colorless liquid. It has two epoxide (oxirane) groups per molecule. Its main use is in modifying epoxy resins especially viscosity reduction whilst flexibilizing. [2] It is REACH registered. [3]
Cosmetics are composed of mixtures of chemical compounds derived from either natural sources or synthetically created ones. [1] Cosmetics have various purposes, including personal and skin care . They can also be used to conceal blemishes and enhance natural features (such as the eyebrows and eyelashes ).
Examples include ethane-1,2-diol or ethylene glycol HO−(CH 2) 2 −OH, a common ingredient of antifreeze products. Another example is propane-1,2-diol , or alpha propylene glycol, HO−CH 2 −CH(OH)−CH 3 , used in the food and medicine industry, as well as a relatively non-poisonous antifreeze product.
2,5-Hexanediol is an organic compound with the formula CH 3 CH(OH)CH 2 CH 2 CH(OH)CH 3. It is both a glycol and a secondary alcohol. [1] It is a colorless water-soluble viscous liquid. [2] [3] [4] The chemical properties are well understood and have been extensively reported and studied. [5]
