Please note this is a raw pigment intended to be dispersed into a liquid medium to make paints. Our raw pigments are not meant for use in cosmetics and are not cosmetic grade. Certain pigments disperse more easily than others in certain liquid mediums. For those difficult to disperse into a liquid of your choice, they will need to be ground by a muller or a mortar and pestle into the medium.
Safety note: Handle all dry pigments with care. Work slowly to avoid generating airborne dust and wear a dust mask for extra protection. Also avoid getting the dust all over your hands. Latex gloves are good at providing skin protection without "getting in the way".
This is a synthetic green pigment, known as a bluish green. It is the PG7 version. Its full name is "Phthalocyanine Green". It's also, like the hansa yellow and carmine red we carry, an organic pigment, which starts out as a dye, so it has a degree of transparency. It's classed as a "polycyclic pigment" in contrast to an "azo pigment" like hanza yellow. One source (see below) points out how well organic pigments mix and cites phthalo and hansa as making "incredibly clean mixtures".
See further below for what makes an organic pigment special.
It may not look it in the picture but phthalo green is considered a bright, high intensity color. Sometimes compared to viridian green, it is often said to be a superior, somewhat less gray color than viridian. It's also less expensive than viridian. The CAMEO database of art materials says { http://cameo.mfa.org/wiki/Phthalocyanine_green } :
"A synthetic organic material composed of chlorinated copper phthalocyanine (chlorinated phthalocyanine blue). Phthalocyanine blue was introduced as a industrial pigment in 1935 and the green derivative was first sold in 1938. Phthalocyanine green is usually adsorbed on an aluminum hydrate base to form a deep vivid green color that is used as a substitute for viridian. The permanent pigment is unaffected by light, heat, and chemicals. Phthalocyanine green is used as a colorant in inks, paints, chalks, leather, pencils, and photographs."
This is a good article on "old" color mixing and the new theory of color mixing:
{ http://www.justpaint.org/color-mixing-you-cant-get-it-unless-you-do-it/} :
"The broad generalization is that Mineral pigments (inorganic) are typically mined from the earth such as the umbers, siennas and ochres. These pigments were augmented at the beginning of the industrial age with the advent of industrially produced mixed metal colors, such as cobalts, cadmiums, zinc and a wide range of manufactured oxide pigments. These pigments are typically more opaque and when mixed together, yield a lower chroma mixture. The Modern (organic) pigments (Quinacridrones, Phthalos and Hansas) are more transparent, have higher chroma and most importantly, when mixed together create incredibly clean mixtures. This is probably the greatest difference between this Modern Theory Color Mixing Set and a classical set. Although a range of Cadmiums in the yellows, oranges and reds will get you incredibly intense and brilliant opaque colors, they tend to mix towards much more muted tones and continued mixing with these colors tends to go towards mud very quickly."
"Organic" + [some color] often means a dye instead of a pigment. Dyes are usually considered transparent, while pigments are opaque. But not always. Some colorants can be semi-transparent and can actually function as dyes to some extent. BASF has a page I like that both cuts to the chase and also gives some technical details on pigments and dyes: https://www.dispersions-pigments.basf.com/portal/basf/ien/dt.jsp?setCursor=1_561069
"...a pigment is any finely divided insoluble black, white or colored solid material...Pigments are always incorporated by simple physical mixing with the medium, and it is this feature that distinguishes them from dyes...dyes are soluble in the media in which they are incorporated and pigments are not...Pigments are classified as either organic or inorganic...Organic pigments are based on carbon chains and carbon rings...Inorganic pigments, chemical compounds not based on carbon, are usually metallic salts."
Although organic pigments have some of the qualities of dyes, such as inferior lightfastness, "Phthalo green is highly stable, being resistant to alkali, acids, solvents, heat, and ultraviolet radiation [UV]". That's from Wikipedia.
The Winsor-Newton site says { http://www.winsornewton.com/na/discover/articles-and-inspiration/spotlight-on-phthalo-green } :
"This green is capable of producing a vast range of useful colour mixtures from transparent subtle natural colours to strong opaque brilliant ones. For this reason it has become the most popular green in use by artists today.
Phthalo green was introduced in 1938 and is a synthetic organic from the group of phthalocyanine dyestuffs. It is a soft green powder insoluble in water, which poses no health hazards. Previous to its introduction, the only greens capable of equal brilliance were the original Emerald Greens which were opaque, more limited in their mixtures, harmful and much less permanent."-
