Quinoline

Also known as: 1-Benzazine, Benzo(b)pyridine, Chinoleine, Quinoleine, Leucoline

IFRA Restriction

This is the maximum allowed percentage of this material in the total finished product, not in the fragrance concentrate.

For example, if a fine fragrance (Category 4A) contains 20% fragrance oil, and IFRA allows 10% of this material, the material can be up to 50% of the fragrance concentrate (10% ÷ 20% = 50%).
