HC Yellow4 has many nicknames, including Acid Yellow Sulfur Dioxide; C 17200; Pigment Yellow I (PY 1); Sacchrominion Bolorant (formerly Permanizing Color 46). it was not only environmentally safe but also highly water-soluble. 

In manufacturing, it is derived from either sulfur dichloride or hydrogen dioxide dioximato by both methods producing the same product.

In some countries, it is an approved food additive under various E numbers with various restrictions on usage. It can use it in paper, dye, plastics. It will often not appear in the ingredient list of goods because it has been added to other ingredients to fortify an assortment of colors.
