HC Blue 12, identified by CAS number 132885-85-9, stands as a pivotal chemical intermediate in the dynamic field of hair coloring. Its chemical name, 4-[N-ethyl-N-(2-hydroxyethyl)amino]-1-(2-hydroxyethyl)amino-2-nitrobenzene, monohydrochloride, points to a complex structure essential for delivering specific color properties and performance in cosmetic formulations.

This compound typically presents as a golden-yellow crystalline powder. Its physical form and inherent chemical characteristics make it a versatile building block for formulators creating innovative hair dye products. The consistent demand for vibrant, stable, and safe hair colorants globally drives the need for high-quality intermediates like HC Blue 12.

As a hair dye intermediate, HC Blue 12 plays a crucial role in achieving desired shades, particularly within the blue or violet spectrum, or serving as a component in complex multi-component formulations designed to create a wide array of hair colors. Its effectiveness and the final color outcome in hair dye products are directly linked to its chemical purity and batch-to-batch consistency. The cosmetic industry relies heavily on intermediates that perform reliably to ensure consumer satisfaction, predictable results, and product safety.

The stringent specifications associated with HC Blue 12 are paramount for its application in cosmetics. A purity level of ≥98.0%, as determined by HPLC, is critical to ensure the desired color development and intensity without interference from unwanted side reactions or off-tints caused by impurities. Similarly, maintaining low levels of residual components such as ash (≤0.5%), loss on drying (≤0.5%), and trace metals like Iron (Fe content ≤50ppm) is vital. High levels of ash or moisture can impact the stability and shelf life of both the intermediate and the final hair dye formulation. Excessive iron content, in particular, can act as a catalyst for degradation reactions, potentially leading to unpredictable color shifts or a loss of color intensity over time. Therefore, strict adherence to these detailed specifications is not merely a matter of chemical quality control but a fundamental necessity for ensuring performance, stability, and safety in finished cosmetic products.

Sourcing high-quality HC Blue 12 requires partnering with experienced and reputable chemical manufacturers and suppliers. Proper storage conditions are also essential to maintain the integrity and quality of the product over time; it should always be stored in a cool, ventilated place, typically provided in standard packaging such as 25 kg drums, though packaging can often be customized according to specific customer requirements. Reliable supply chain management is key to ensuring that manufacturers of hair care products have consistent and timely access to this essential raw material.

For companies in the cosmetic or chemical industry seeking a dependable manufacturer and supplier of HC Blue 12, understanding the importance of detailed specifications, verified purity, and consistent availability is crucial for their production processes. When looking to buy or purchase this vital intermediate, engaging directly with established chemical suppliers who can guarantee product quality, provide necessary technical data, and ensure supply chain reliability is highly recommended. Inquiries regarding price and bulk ordering options are standard practice in the procurement process for essential cosmetic raw materials like HC Blue 12.
