2,4-Diaminophenoxyethanol Sulfate, also known by its chemical name [4-(2-hydroxyethoxy)-1,3-phenylene]diammonium sulphate, is a synthetic compound primarily used in the cosmetic industry as a hair dyeing agent. This ingredient is a member of the aromatic amine family, which is known for its ability to provide vibrant and long-lasting color to hair.
The history of 2,4-Diaminophenoxyethanol Sulfate in cosmetics dates back to the early developments in synthetic hair dyes. As the demand for more reliable and varied hair coloring options grew, chemists sought to create compounds that could offer consistent results while being relatively safe for consumer use. This particular compound emerged as a solution due to its effective dyeing properties and its ability to bond well with hair fibers.
The production of 2,4-Diaminophenoxyethanol Sulfate involves a series of chemical reactions starting with phenol derivatives. These derivatives undergo a process of nitration, reduction, and subsequent reactions with ethylene oxide to introduce the hydroxyethoxy group. Finally, the compound is treated with sulfuric acid to form the sulfate salt, which is the form used in cosmetic products. This synthesis ensures that the ingredient is stable and suitable for use in various hair dye formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of 2,4-Diaminophenoxyethanol Sulfate:
2,4-Diaminophenoxyethanol Sulfate is primarily used as a hair dyeing agent. This means it plays a crucial role in the formulation of hair color products. When applied, it helps to impart color to the hair strands, allowing for a wide range of hair color options, from natural shades to more vibrant and bold hues. This ingredient is particularly valued for its ability to provide long-lasting and even color distribution, ensuring that the hair color looks consistent and vibrant over time.
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).
2,4-Diaminophenoxyethanol Sulfate is generally considered safe for use in hair dyeing products, but like many cosmetic ingredients, it can cause adverse reactions in some individuals. Here are some potential side effects of topical application:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of 2,4-Diaminophenoxyethanol Sulfate during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Adverse reactions to 2,4-Diaminophenoxyethanol Sulfate are relatively uncommon, but they can occur. It is recommended to perform a patch test before widespread usage to ensure there is no adverse reaction.
In terms of comedogenicity, 2,4-Diaminophenoxyethanol Sulfate scores a 0 on a scale of 0 to 5, meaning it is considered non-comedogenic. This indicates that it is unlikely to clog pores and should be suitable for individuals prone to acne, blemishes, or breakouts.
