Quy định
EU: Approved as colorant in cosmetics (C
CI 15850, commonly known as Amaranth or FD&C Red No. 1, is a synthetic azo dye widely used in cosmetics to impart vibrant red-pink coloration. This water-soluble colorant has been employed in the cosmetic industry for decades and is recognized by multiple regulatory bodies including the European Union and FDA. The compound is particularly valued in lip products, blushes, and other color cosmetics where stability and uniformity of color are paramount.
As a synthetic colorant, CI 15850 functions through light absorption and reflection properties of its chromophoric structure. The azo double bond (-N=N-) in its molecular framework is responsible for absorbing light in the visible spectrum, specifically in the blue region, which results in the perception of red-pink color. When incorporated into cosmetic formulations, this colorant dissolves or disperses evenly throughout the product matrix, providing consistent color to every application.
Nghiên cứu khoa học
Regulatory authorities including the European Food Safety Authority (EFSA) and FDA have evaluated CI 15850 for cosmetic use, establishing acceptable daily intake (ADI) levels based on animal toxicity studies. While the colorant is lipophilic in its original form, the disodium salt formulation used in cosmetics is water-soluble, which impacts absorption and bioavailability. Multiple safety assessments have confirmed that when used within established concentration limits in non-ingested cosmetic products, CI 15850 presents minimal risk to human health.

Công dụng:
Both are synthetic azo colorants used in cosmetics. CI 15850 provides deeper red tones while CI 15985 is more yellow-orange. CI 15850 has broader regulatory approval globally, whereas CI 15985 faces more restrictions in certain regions.
CI 15850 offers superior color intensity and consistency compared to natural alternatives. However, natural colorants avoid synthetic compound concerns. CI 15850 provides more vibrant, consistent pigmentation.

Bạn có biết?
CI 15850 was originally derived from coal tar sources in the early 1900s, making it one of the oldest synthetic colorants still in use today
The name 'Amaranth' comes from the amaranth plant, though the cosmetic colorant is entirely synthetic and not derived from the plant itself
