SMART TECHNICAL PRODUCT ADVISOR
Describe the requirement and see candidates with evidence.
The advisor only matches verified catalogue fields. Final product, grade and dosage require validation by the technical team using TDS/SDS and site data.

Dyes and Colourants selection guide
Products providing controlled colour or opacity in detergents, textiles and general industrial formulations. This category page helps compare products by application, technical function and selection criteria. Final grade, purity, active content and regulatory suitability must be confirmed product by product using current TDS/SDS.
Check dissolution/dispersion, pH, temperature and light stability within the target formulation.
Confirm target-market requirements, colour index or manufacturer code and batch documentation before ordering.
KNOWLEDGE CENTRE
Dyes and Colourants frequently asked questions
Key points for grade, application, documentation and safe-use assessment in this product group.
Is the colour name alone sufficient when selecting a colourant?
No. Chemical class, colour index or grade code, solubility or dispersion behaviour, colour strength, pH and temperature stability and target regulations should be reviewed together.
Why should shade be checked between batches?
Raw-material and process variation may affect visible shade or colour strength. Incoming quality control should compare the batch with an approved standard and adjust when required.
Why does the distinction between a soluble dye and pigment matter?
Solubility, dispersion needs, substrate retention, migration and filtration behaviour can differ. Select the type according to the carrier, target material and process equipment.
How is dosage established?
Determine it progressively through a small-scale colour-matching study considering target shade, base colour, product strength and process losses.
How is suitability verified for food, cosmetic or toy applications?
Do not rely on the colour name alone; verify permitted use, purity criteria, restricted-substance and migration documents for the supplied grade against the target regulation.
