Sennelier Oil Pastel is a product that contains the same components used in all Sennelier colors: first quality pigments, a very pure synthetic binder and a mineral wax. The pigments are ground with an inert, non-drying binder that does not oxidize and therefore will not affect the film's durability or the supports. This base is then mixed with wax (pH neutral). The balance of this mixture gives Sennelier oil pastels a particular smoothness, a creamy texture that allows great freedom in pictorial expression.

Sennelier oil pastels have an exceptional concentration of pigment which gives them great coloring power, coverage, a great liveliness of tones and a very good resistance to light (except for metallic and fluorescent tints).

The remarkable properties of its components and their carefully studied dosages give Sennelier oil pastels unique characteristics that make them the world's leading brand.
