P-AMINOPHENOL SULFATE

Description

P-Aminophenol Sulfate is a crucial oxidative hair dye precursor widely used in the cosmetic industry. This water-soluble compound is a key component in permanent hair coloring formulations, primarily responsible for producing warm brown to black shades. When combined with hydrogen peroxide and other coupling agents, it undergoes a chemical reaction that creates larger, colored molecules within the hair shaft.

The sulfate form of p-aminophenol offers improved stability and solubility compared to its free base counterpart. This enhanced stability contributes to a longer shelf life for hair dye products and ensures consistent performance during application. P-Aminophenol Sulfate typically appears as white to light pink crystalline powder and is often used in concentrations ranging from 0.1% to 3% in hair dye formulations.

While effective for hair coloration, it's important to note that p-aminophenol sulfate can cause skin sensitization in some individuals. Proper patch testing is recommended before use, and it should always be utilized in accordance with regulatory guidelines. When formulating with this ingredient, it's essential to consider its optimal pH range and potential interactions with other dye components to achieve the desired color results and minimize adverse reactions.
