M-Aminophenol, also known as 3-Aminophenol or CI 76545, is a chemical compound that finds its primary use in the world of cosmetics as a hair dyeing agent. This ingredient is a type of aromatic amine, which means it contains an amino group attached to a benzene ring. The “M” in M-Aminophenol stands for “meta,” indicating the position of the amino group relative to the hydroxyl group on the benzene ring.
The history of M-Aminophenol in cosmetic products dates back to the early 20th century when synthetic dyes began to replace natural dyes for their consistency and range of colors. Over the years, M-Aminophenol has become a staple in the formulation of permanent and semi-permanent hair dyes due to its ability to produce a variety of shades, particularly in the brown and black spectrum.
M-Aminophenol is typically synthesized through a chemical process that involves the nitration of phenol to produce nitrophenol, which is then reduced to aminophenol. This process ensures a high degree of purity and consistency, making it suitable for use in cosmetic formulations. The resulting compound is a crystalline solid that is soluble in water, making it easy to incorporate into hair dye products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of M-Aminophenol:
M-Aminophenol 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 used in hair dye products, M-Aminophenol reacts with other chemicals to produce a variety of shades, allowing for a wide range of hair color options. This ingredient is particularly valued for its ability to provide consistent and long-lasting color results, making it a popular choice in both permanent and semi-permanent hair dye products.
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, also known as 3-Aminophenol (CI 76545), is generally considered safe for use in hair dyeing products when used as directed. However, like many cosmetic ingredients, it can cause side effects in some individuals.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of M-Aminophenol during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to M-Aminophenol are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is recommended to perform a patch test before widespread usage.
In terms of comedogenicity, M-Aminophenol has a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating indicates that it is unlikely to clog pores or cause acne, making it generally suitable for individuals prone to blemishes or breakouts.
