CI 47005: Quinoline Yellow
The yellow-green colour terrainQuinoline yellow has a distinct identity within the yellow palette. Its colour can join other dyes and pale ingredients to build a finished shade rather than stand alone.Visual references: D&C Yellow 10, Quinoline Yellow: Acid Yellow 3, CI47005

Yellow has more than one material identity. CI 47005 is the code associated with quinoline yellow, a colour that can be a quiet partner in a wash bar rather than a bright statement on its own. Its story explains why the words yellow, salt and mixture each need their own careful meaning.

A quick answer

CI 47005 is a synthetic quinoline-family yellow colour associated with Acid Yellow 3 and D&C Yellow 10. Its official identity describes a mixture of related sodium salts, rather than a single botanical extract. It can contribute colour to solid cosmetics. A current soap-free wash bar lists it beside a green dye and titanium dioxide, illustrating how a yellow ingredient can be one part of a combined shade.

The yellow you may not notice separately

A current solid wash bar lists CI 47005 with green CI 61570 and titanium dioxide. This is a useful example of a colour ingredient contributing to a palette rather than taking the starring role. The finished appearance is what those materials make together.

When the object looks pale or restrained, it is easy to imagine that no thought has gone into colour. A short pigment list can reveal otherwise. Small visual adjustments can be part of making a familiar product recognisable and pleasant to use, even when the result is deliberately quiet.

A different yellow from tartrazine

Quinoline Yellow, Acid Yellow 3 and D&C Yellow 10 are names associated with CI 47005. Tartrazine, commonly associated with CI 19140 or Yellow 5, is a different colour identity. The shared word yellow is a description of the visible family, not proof of identical materials.

This distinction becomes useful when comparing products across markets. One source may lead with a CI code, another with a colour name. Keeping the complete identity lets you follow the right material without needing to memorise every possible cosmetic shade.

One ingredient name can describe related components

The official Yellow 10 identity describes a mixture of related sodium salts of sulfonated colour compounds. That is a specific kind of material description: the named colour preparation is itself composed of related forms, before it joins the larger cosmetic formula.

This is an interesting reminder that an ingredient is not always a single, isolated molecule. Some cosmetic names refer to mixtures defined by their composition and specifications. The useful question is what material the name identifies, rather than assuming every line on a label must describe one chemically simple substance.

2

The colour has a manufactured route

Official information describes a manufactured quinoline colour, followed by a chemical step that produces the sulfonated preparation. The final material is a defined colour additive. Its identity is separate from yellow plant powders such as turmeric.

That difference gives both materials room for their own stories. A turmeric powder carries the complexity of a ground botanical; CI 47005 is a prepared synthetic colour. A finished product’s yellow appearance does not tell you which route was chosen. The ingredient list can make that source of colour much clearer.

12

A sodium salt is not automatically a grain of salt

Sodium salts are part of this dye’s official identity. That wording does not mean the ingredient is Sodium Chloride or that it supplies the texture of a salt scrub. The rest of the name tells you which material is involved.

For readers, this is a small but transferable lesson. The same chemical word can occur in ingredients with very different roles. Here, the prepared colour contributes to appearance. In another part of the atlas, Sodium Chloride may have a separate structural or formulation purpose. A shared word does not erase those differences.

See the palette, then the product

A yellow colour ingredient can join a green one, a pale background and a solid cleansing base. Each part contributes something different. Looking at the palette is a useful way to appreciate the object without expecting the colour to explain its entire performance.

The boundary is that a colour identity does not establish a care effect, a food-use conclusion or the exact shade of another formula. What it does offer is a precise, traceable material story. CI 47005 turns an apparently simple yellow into a glimpse of manufacturing, naming and visual composition.

Questions you might have

Is quinoline yellow the same as Yellow 5?

No. CI 47005 is associated with D&C Yellow 10 or quinoline yellow. CI 19140 is associated with Yellow 5 or tartrazine. Both belong to the everyday category yellow, but they identify different colour materials. The complete code or established colour name is the useful detail when following an explanation.

14

Why does one colour ingredient contain a mixture?

Some named ingredients are defined preparations rather than a single pure molecule. The official Yellow 10 identity describes a mixture of related sodium salts. That mixture is the colour material supplied before it becomes one component of a finished cosmetic. Ingredient names can therefore describe organised complexity, even when the label uses one short line.

2

Does a yellow dye mean the product contains turmeric?

No botanical source follows from a yellow appearance. CI 47005 is a synthetic colour identity, separate from turmeric powder. A product could contain one, the other or both for different purposes. The label identifies the materials, while the finished shade reflects how the maker combines them.

12

One useful thought

CI 47005 is a useful yellow to know because it separates several things we often merge: a hue, a named chemical family and a prepared mixture. Its place in a solid wash bar shows the practical result—a colour chosen as part of a palette, with a distinct material journey behind it.
