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 Green

Pigment code
PG7
Type
organic
Chemical name
polychlorinated copper(II) phthalocyanine
Chemical formula
C32H3Cl13CuN8 to C32HCl15CuN8 or C32H16CuN8Cl15 (PG7) or C32Br6Cl10CuN8 (PG36)
Properties
Phthalo Green is a transparent, cool, bright, high intensity color used in oil and acrylics. It comes from a Phthalocyanine Blue pigment where most of the hydrogen atoms have been replaced with chlorine, forming highly stable molecules. It has similar pigment properties and permanence to Phthalo Blue. It is slow drying and an excellent base color for mixing a range of bright greens. Phthalo Green is considered a very good alternative to Viridian because it is intense and mixes well and can be used to emphasize mineral colors in various tints. However, its tinting strength is very high, so it can overpower other colors. This pigment most closely resembles the discontinued and toxic Verdigris.
Permanence
Phthalo Greens are completely lightfast and resistant to alkali, acids, solvents, heat, and ultraviolet radiation. 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.

Titanium White

Pigment code
PW6
Type
inorganic
Chemical name
titanium dioxide
Chemical formula
TiO2
Properties
Titanium White is the most brilliant of the white pigments. It is considered an all purpose oil color useful in all techniques and the best all around white. Its masstone is neither warm nor cool, placing it somewhere between Lead White and Zinc White. It is less prone to cracking and yellowing than Lead White, but it still yellows easily. Titanium White dries slowly in oil form, more slowly than Lead White but more quickly than Zinc White. It is opaque in oil and acrylic forms and semi-opaque in watercolor form. This pigment has good chemical stability, and its tinting strength is superior to both Lead White and Zinc White.
Permanence
Titanium White has excellent permanence and lightfastness.
Toxicity
Titanium dioxide is highly stable and is regarded as non-toxic.
History
Titanium is the ninth most abundant element in the Earth's crust, however mineral deposits that are economical to mine are less common. Titanium dioxide was first discovered in 1821, although it could not be mass produced until 1919. Widespread use of the pigment began in the 1940s. Since that time, it has become the most commonly used white pigment. The name comes from the Latin word Titan, the name for the elder brother of Kronos and ancestor of the Titans, and from the Greek word tito, meaning day or sun.
