Potassium Bromate CAS#7758-01-2 as a Cosmetic Ingredient: Technical Parameters and Specifications
Introduction: Application Background of Potassium Bromate in the Cosmetic Industry
In recent years, the fast growth of the cosmetic industry has been accompanied by increasing consumer focus on both safety and product performance. Under these circumstances, potassium bromate, a chemical raw material with specialized functions, has gradually attracted the attention of cosmetic researchers. Potassium bromate (KBrO₃), with a molecular weight of 167.001 and CAS No. 7758-01-2, is a white crystalline powder. In cosmetic applications, it is mainly used as an oxidizing agent and hair treatment ingredient, playing an especially important role in perm formulations.
Product Characteristics: Physicochemical Properties of Potassium Bromate
Basic Physical Properties
Potassium bromate appears as white or colorless trigonal crystals or granules with a density of 3.27 g/cm³ at 17.5°C. It has a high melting point of 434°C and decomposes into potassium bromide and oxygen at about 370°C. This thermal stability enables it to maintain consistent performance during cosmetic processing. In terms of solubility, it dissolves readily in water (49.75 g/100 mL at 100°C), is slightly soluble in ethanol, and insoluble in acetone, providing flexibility in cosmetic formulation design.
Chemical Properties
As a strong oxidizing agent, potassium bromate possesses powerful oxidative activity, allowing it to effectively modify hair structure in perming products. At the same time, this reactivity requires careful handling, as it should not be mixed with organic substances or reducing agents to avoid hazardous reactions. In cosmetic applications, professional formulators strictly regulate its concentration and usage conditions to ensure product safety.
Technical Parameters: Standards for Cosmetic-Grade Potassium Bromate
Purity Requirements
Cosmetic-grade potassium bromate must meet high purity standards, typically 99.5% or above. This ensures both safety and effectiveness in cosmetic formulations. High purity minimizes the risk of irritation from impurities while maintaining consistent performance.
Impurity Control
Strict limits are placed on heavy metals, especially harmful elements such as lead and arsenic, which could cause skin irritation or long-term health risks. Advanced purification techniques allow qualified suppliers to reduce impurity levels to extremely low values that comply with cosmetic industry standards.
Packaging and Storage
Cosmetic-grade potassium bromate is usually packed in 25 kg fiber drums lined with polyethylene bags to protect the product during transport and storage. As a secondary inorganic oxidizer, it must be stored in a cool, dry, and well-ventilated area, away from heat, flames, organic materials, and reducing agents. Proper storage is essential to preserve both quality and safety.
Application Outlook: Future Use in Cosmetics
Although potassium bromate is strictly regulated in the food industry, its role as a professional hair-treatment ingredient in cosmetics continues to grow. With ongoing advances in perming technology and rising consumer demand for customized hairstyling, potassium bromate shows strong application potential. Reliable ingredient suppliers support industry innovation by offering high-purity, tightly controlled products.
Conclusion: Importance of Professional Selection
When choosing cosmetic ingredients, safety and professional standards are critical. As a functional raw material, potassium bromate requires expert handling and strict quality control. By sourcing from reputable suppliers, cosmetic manufacturers can obtain high-quality potassium bromate that helps deliver safe and effective beauty products. As industry standards continue to improve and technology advances, the role of potassium bromate in cosmetics is expected to become even more established and refined.
