About this illustration
CI 45410Red 28 Lake
The rose-toned colour planeIllustrated as a prepared red dispersion, this colour has a practical route into an oily cosmetic. Keeping Red 28 Lake beside CI 45410 gives a more specific identity than the number alone.

A rosy perfume balm can look like a tiny jewel. Behind that colour may be CI 45410, a manufactured red whose story includes a surprisingly useful distinction: a colour molecule, its salt and a prepared pigment need not arrive in the same physical form. That helps explain how red finds its place in an oily solid.

A quick answer

CI 45410 is a synthetic red colour identity associated with the xanthene family and names including Acid Red 92 and Red 27/28. Exact preparations differ. A current perfume balm, for example, explicitly declares CI 45410 as Red 28 Lake. Its role there is visual colour. Recognising the family is a starting point; retaining the additional name explains more about the material actually chosen for that product.

The small jewel in the tin

There is a reason a coloured balm can be pleasurable before it reaches the skin. Its surface, translucency and shade turn a practical object into something inviting. CI 45410 belongs to that visible construction. It supplies colour while other ingredients build the balm and carry its scent.

A current solid perfume label pairs Red 28 Lake with Yellow 5 Lake. That is a lovely glimpse of colour being composed rather than merely added. The red is one part of a palette, much as a single scent material is one part of an aroma. The two palettes serve different senses.

A family name behind the red

Xanthene is the dye family associated with CI 45410. It describes a chemical arrangement rather than a botanical source. Names such as Phloxine B or Acid Red 92 may appear in ingredient references, while a finished cosmetic may declare the CI number with a more specific colour name.

Those overlapping names are useful when following a material across different systems. They also explain why a search can produce several descriptions of apparently similar reds. The numerical reference anchors the conversation, but the extra words remain valuable: they can distinguish preparations that a short list alone leaves unexplained.

A related red can take another form

The official identities of Red 27 and Red 28 reveal a particular relationship. Red 27 is based on tetrabromotetrachlorofluorescein; Red 28 is principally its disodium salt. You need not pronounce either name to appreciate the idea: changing the form of a colour material can matter to how it is prepared and used.

That is more informative than treating every red in the family as one interchangeable powder. The colour family gives continuity, while the form supplies another layer of detail. In the workshop, both identity and preparation are part of choosing a colour for a particular cosmetic medium.

Red can arrive as a prepared paste

One commercial colour dispersion combines CI 45410, declared as Red 28 Lake, with Sorbitan Oleate and Octyldodecanol. It is supplied as a red liquid paste for uses including lipstick and oily gels. The colourant and its carrying materials are deliberately brought together before the finished cosmetic is made.

This is an interesting explanation for a long label. Several names may describe a useful supplied preparation rather than separate dramatic claims. A pigment needs to be distributed through its surroundings. Preparing a paste is one practical route to incorporating colour in an oily system with a smooth, even appearance.

The pink does not make the perfume

A perfume balm brings scent, touch and colour into a very small object. Its red colour ingredient is not the name of its perfume, even when the shade suggests berries or flowers. The aromatic impression comes from the fragrance materials selected for that product.

Separating those sensory stories makes the object more interesting. A rosy surface can express the mood of a perfume without being an extract of the flower pictured on the packaging. Colour design and scent design can support one another while remaining different parts of the formula.

Let the extra words do useful work

When a label says Red 28 Lake beside CI 45410, keep that detail. It tells a more specific story than the number by itself. A different product with a similar colour family may use another preparation or a different combination of colourants.

For everyday choosing, enjoy the finished colour and use the product for its stated purpose. The presence of this code alone does not tell you how strongly it colours the skin or hair. Its value as an atlas entry is more precise: it reveals how a familiar rosy solid can contain a carefully prepared, manufactured colour material.

Questions you might have

Is this red extracted from a flower?

CI 45410 is a synthetic colour identity. A flower may inspire the finished shade or perfume, but that is a separate story from the source of this colourant. A cosmetic can contain botanical materials and a manufactured red at the same time, with each contributing a different part of the experience.

Why does one label add Red 28 Lake?

That wording identifies the preparation more specifically. The current perfume-balm example uses that additional name, and a commercial dispersion declares it too. Retaining it helps distinguish the pigment chosen for that product from the broader family of names attached to CI 45410 in ingredient references.

35

Is it the same as CI 45410:2?

The colon and final digit should be retained when supplied. Manufacturer listings distinguish preparations carrying CI 45410:2, while some finished products declare Red 28 Lake under CI 45410. The helpful approach is to follow the complete declaration for the particular product, rather than silently adding or removing the suffix.

One useful thought

CI 45410 offers a glimpse of the craft behind a rosy solid: a red family, a chosen preparation and a way to distribute it through an oily medium. Keeping the additional colour name makes the story clearer. The beauty lies in seeing how a very small object is composed for several senses.
