M-Aminophenol Sulfate, also known as Bis[(3-hydroxyphenyl)ammonium] sulphate (CI 76545), is a chemical compound primarily used in the cosmetic industry for hair dyeing purposes. This ingredient is derived from aminophenol, a type of organic compound that features both an amine and a phenol group. The sulfate part of the compound helps to stabilize it, making it more effective and easier to incorporate into various formulations.
The history of M-Aminophenol Sulfate in cosmetics dates back to the early 20th century when synthetic dyes began to replace natural dyes due to their consistency and vibrant colors. Over the years, the compound has been refined and tested to ensure its safety and efficacy in hair dye products. Its ability to provide a wide range of shades and its compatibility with other dyeing agents have made it a popular choice among manufacturers.
The production of M-Aminophenol Sulfate involves a series of chemical reactions starting with the synthesis of aminophenol. This is typically achieved through the nitration of phenol followed by reduction. The aminophenol is then reacted with sulfuric acid to form the sulfate salt. This process ensures that the final product is pure and suitable for use in cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of M-Aminophenol Sulfate:
M-Aminophenol Sulfate is primarily used as a hair dyeing agent. This means it plays a crucial role in the formulation of hair dyes, helping to impart color to the hair. When you use a hair dye product containing M-Aminophenol Sulfate, the ingredient works by penetrating the hair shaft and depositing color molecules, resulting in a change of hair color. This can range from subtle highlights to a complete color transformation, depending on the formulation and concentration used.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
M-Aminophenol Sulfate, while effective as a hair dyeing agent, comes with certain considerations regarding its safety, suitability, and allergenic potential.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of M-Aminophenol Sulfate during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Side effects and adverse reactions from M-Aminophenol Sulfate are relatively uncommon, but they can occur. To minimize the risk, it is recommended to conduct a patch test before widespread usage.
In terms of comedogenicity, M-Aminophenol Sulfate scores a 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low score indicates that it is unlikely to clog pores and cause acne or breakouts, making it generally suitable for individuals prone to blemishes.
