Which type of dye would be used to color oils, waxes, and shoe polishes?
Correct answer: B. Solvent dyes
- A. Acid dyes
- B. Solvent dyes
- C. Direct dyes
- D. Vat dyes
Explanation
Solvent dyes are ideal for coloring non-polar substances such as oils, waxes, and shoe polishes because they are soluble in organic solvents and can adhere to substances with similar chemical properties. Acid dyes, direct dyes, and vat dyes are primarily used for textile fibers and are not suitable for non-polar materials. Acid dyes work with protein fibers, direct dyes with cellulose fibers, and vat dyes require a reduction process that is not applicable to non-polar substances.
