For cosmetic chemists and procurement managers, selecting the right colorants is paramount to product appeal and safety. Rhodamine B (CAS 81-88-9) stands out as a synthetic fluorescent dye renowned for its vibrant pink to red hues and distinctive fluorescence. As a leading manufacturer and supplier in China, we understand the critical requirements for high-purity ingredients in the cosmetics industry. This article delves into the properties, applications, and sourcing considerations for Rhodamine B, ensuring you can confidently procure this valuable ingredient.

Rhodamine B, chemically known as C28H31ClN2O3, is a water-soluble and ethanol-soluble dye that exhibits a strong blue-red fluorescence upon dilution. Its stability makes it a preferred choice for various cosmetic products. However, regulatory guidelines often restrict its use to non-eye, non-oral, and non-lip products. This means formulation chemists should carefully consider its application in items like bath lotions, shampoos, and cold creams, where it can impart an attractive visual signature.

When you buy Rhodamine B, quality and consistency are key. As a reputable manufacturer, we ensure our Rhodamine B meets stringent purity standards, typically above 99.5%. This high level of purity is crucial for predictable performance and to avoid unwanted side reactions or color variations in your final product. Procurement managers seeking a reliable supplier for cosmetic ingredients will find our commitment to quality assurance invaluable. Understanding the market and sourcing from established manufacturers like ourselves ensures you receive a product that meets international standards and regulatory requirements.

The fluorescence of Rhodamine B can be a significant advantage, adding a unique visual appeal to products. However, its effectiveness can be influenced by factors like pH and concentration. Formulation chemists often need to test its performance within specific cosmetic matrices. For those looking to purchase Rhodamine B for their formulations, partnering with a manufacturer that can provide detailed technical data sheets (TDS) and safety data sheets (SDS) is essential. This information is vital for safe handling and effective incorporation into cosmetic products.

Beyond cosmetics, Rhodamine B is also extensively used in textile dyeing, paper printing, and as a colorant in paints and plastics, showcasing its versatility. However, for cosmetic applications, sourcing from a supplier that specializes in high-grade ingredients is paramount. We, as a dedicated manufacturer and supplier, are committed to providing the chemical industry with high-quality Rhodamine B.
