| Résumé : |
For cosmetics and personal care products, the term resin is applied to a group of substances obtained as gums from trees or those that are manufactured synthetically. The term, synthetic resins, dates from the years when synthetics began to replace natural resins. Synthetic resins are polymeric materials, which are better known as plastics. There are two important classes of synthetic resins: thermosetting resins and thermoplastic resins.
A thermosetting resin is a high molecular weight polymer that solidifies irreversibly when heated. Thermoplastic resins are polymeric materials that can be softened and resoftened indefinitely by the application of heat and pressure, provided that the heat that is applied does not chemically decompose the resin.
Hydrocarbon resins are based on a petroleum feedstock, le, a synthetic source. Hydrogenation is primarily used to improve calor and stability of the resin by removing vulnerable double bonds. Partial and selective hydrogenation are methods used to produce resins with broad compatibility and good stability. |
