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".
Note: This is a low density powder, so buying it by weight gives you a lot by volume.
This is a bright yellow "azo" pigment which makes it a pigment derived from a dye and thus gives it a degree of transparency. Carmine red and phthalo green are two other organic pigments we carry that start as dyes. We originally picked it because our shop carried only an iron oxide derived yellow pigment at the time (yellow ochre) and Orasol yellow dyes. I was surprised to find that the yellows I knew of, like cadmium yellow, chrome yellow, or naples yellow are all pretty toxic (when you're handling the dry pigment). Cobalt yellow would be a candidate but there seem to be questions about its stability and it's pretty transparent. To top it off, it's very expensive. So hansa yellow, which is relatively inexpensive, seemed to be the best choice.
Hansa yellow is an "azo" organic pigment, specifically a "monazo" yellow. "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."
You should consider that this is a "partial" dye, since it's an organic pigment, and that all dyes are not as lightfast as mineral pigments. Keep paintings out of direct sunlight.
The Wiki article on Hansa Yellow is here (they call it by its chemical name, arylide):
https://en.wikipedia.org/wiki/Arylide_yellow
"Arylide yellow [or arylamide], also known as Hansa yellow and monoazo yellow, are a family of organic compounds used as pigments. They are primarily used as industrial colorants including plastics, building paints and inks. They are also used in artistic oil paints, acrylics and watercolors. These pigments are usually semi-transparent yellows and yellow-greens. Related organic pigments are the diarylide pigments. Overall, these pigments have partially displaced the toxic cadmium yellow in the marketplace."
The CAMEO database is more informative than Wiki in this case:
http://cameo.mfa.org/wiki/Hansa_yellow
"Originally a brand name [Hoechst AG] for a series of bright yellow synthetic organic pigments. Hansa yellow is now a commonly used designation for this class of yellow monoazo colorants. They are also called arylamide yellows. Developed in Germany in the early 20th century, Hansa yellow was the first permanent organic yellow pigment. It was available for artists paints about 1915. The insoluble colorants have good lightfastness and weather resistance but are susceptible to bleeding in some media and discoloration when heated. They were commonly used as inexpensive substitutes for cadmium yellows in paints, plastics, rubber and coated paper. Recently, they have been superseded by diarylide and vat yellows.....Synonyms...arylamide yellow; Monolite yellow; Talens' yellow; Pigment Yellow 1, 3, 5 and 10"-

Came looking for lamp black (didn't want to try making my own), found lots of other interesting things as well. Appreciate the message from the shop owner about how to open the package to avoid making a mess. Everything looks great; thanks so much!
