Usage

Uses

Used in Personal Care and Cosmetics Industry:
1-(hydroxymethyl)-imidazolidin-2-one is used as a preservative for [application reason] to extend the shelf life and prevent contamination of personal care products and cosmetics. Its water solubility and stability at a wide pH range make it suitable for a variety of formulations.
However, it has been associated with skin sensitization and allergic reactions in some individuals, leading to concerns about its safety. Despite this, it is still used in many products as a preservative to maintain product quality and safety.

Thermal Condensation in Solid State of N-Hydroxyalkyl-2-imidazolidinone

N-(1-Hydroxyalkyl)-2-imidazolidinones (1) were prepared by a reaction of 2-imidazolidinone with form-, acet-, propion-, and butyraldehyde.In all of these reactions, 1 were unstable and moisture-sensitive substances.The pyrolysis reaction of 1 was found to be a thermal decomposition via a condensation reaction stage after a molten state.The condensation stage obeyed 1/2- and the first-order kinetics.The kinetic data regarding the condensation reaction were evaluated by analyses of the dependences of the area of isothermal DSC curves upon the reaction time.It may be concluded that the difference provided by the reaction order and the activation parameters were caused by the number of the hydrogen atoms on the β-carbon atom adjacent to the carbon attacked the hydroxyl group of side chain in 1.In the decomposition by electron impact of 1 and dimer of 1, the cleavage of the five-membered ring which corresponded to the molecular-ion peak for 2-imidazolidinone (m/z 86) was considered to take place after a successive cleavage of the side chain .On the basis of both kinetic studies and ESR or Mass spectral observations, the dimerization mechanism is fully discussed.
