Synthrapol aids acid dye in penetrating the fiber
Jacquard Turquoise Acid Dye at Amazon
(Also see About Acid Dyes.)
Acid dyes are used on animal fibers such as wool, in addition to silk and nylon. They should not be used on cellulose fibers such as cotton, nor on synthetics other than nylon.
PRO Chemical & Dye sells the PRO WashFast Acid dyes shown in the table below, which they indicate are pure, unmixed colors. They also sell mixtures, which are not listed below. Most of these pure dyes are the Nylomine Dyes referred to in Karren Brito's SHIBORI: creating color and texture on silk. Nylomine is just one of many textile dye brand names that have been applied to these dyes, but, as the name indicates, these are dyes that tend to work well on nylon.
All of these dyes have been listed as being classified as fast milling dyes, with the exception of acid black #172, which is listed elsewhere as a 1:2 metal complex dye. However, I suspect that some may belong to another subgroup of acid dyes. Note that, in spite of the name, not all of these dyes are particularly washfast (see washfastness data on the lightfastness page); as a rule, you should wash fabrics dyed with these dyes in cool water only. If washfastness is your top priority, I strongly recommend using Lanaset dyes or boiling your protein fiber in Remazol dyes.
A few of the dyes in Jacquard's Acid Dyes lineup are the same as ProChem & Ciba's Washfast Acid dyes; for example, ProChem's Rhodamine Red B is the same as Jacquard's Hot Fuchsia, or Colour Index Acid Red 52. Color Index Acid Blue 7 is ProChem's Turquoise and Jacquard's Turquoise, and Colour Index Acid Blue 25 is ProChem's National Blue and Jacquard's Sapphire Blue, while Colour Index Acid Blue 113 is ProChem's Navy and Jacquard's Navy Blue. However, most of dyes in the two lines of dyes are completely different chemicals. It is worth noting that some acid dyes cannot be used together. The dyes in each brand of dye are selected for compatibility, within that brand, but dyes that are found in only one brand just might be incompatible with those found only in the other.
You can purchase PRO brand dyes from PRO Chemical & Dye or from one of their retailers. Maiwa Handprints sells Ciba Washfast Acid Dyes, which seem likely to be the same.
