Sennelier Oil Pastels are a benchmark in the art world: lipstick soft, highly pigmented pastels made in France with the same top-quality components found in all Sennelier colors.

Developed in collaboration with Pablo Picasso, they combine pure pigments, an exceptionally pure synthetic binding medium, and pH-neutral mineral waxes to create an oil pastel unlike any other.

Each stick is packed with an extraordinarily high pigment load, giving it superior covering power, exceptional brightness, and a high degree of lightfastness (with the exception of metallic and fluorescent colors).

The balance of wax and binder results in a uniquely rich, smooth texture that allows artists to work with freedom, whether creating thin veils of color or bold, impasto-like strokes.

The binder is inert and non-siccative, meaning it won’t oxidize, crack, or alter over time. Combined with mineral wax, this ensures excellent surface stability and makes blending and layering effortless.

Phthalo Blue

Pigment code
PB15:3
Type
organic
Chemical name
beta copper phthalocyanine
Chemical formula
C32H16CuN8
Properties
Phthalo Blue PB15:3 is a structural variant of Phthalo Blue PB15 that produces more greenish tones.
Permanence
Phthalo Blues are completely lightfast and stable and are permanent for all paint uses. They are currently used in inks, coatings, and many plastics due to their stability and are considered a standard pigment in printing ink and the packaging industry.
Toxicity
Phthalo Blues have no significant hazards, although those made before 1982 contained some PCBs (polychlorinated biphenyls).
History
Developed by chemists using the trade name Monastral Blue, the organic blue dyestuff now known as Phthalo Blue was presented as a pigment in November 1935 in London. Its discovery was accidental. The dark color was observed in a kettle where a dye was being made from a British dyestuff plant. The demand for such a pigment came from commercial printers who wanted a cyan to replace Prussian Blue.
