1,3-Bis(2,4-Diaminophenoxy) Propane HCl (13BIS) is a specialized ingredient used in oxidative hair dye formulations. Here's how it functions:

Role in Hair Dye:

• Coupler: 13BIS acts as a coupler in hair dye systems. Couplers don't produce color on their own, but they react with oxidative bases (primary intermediates) in the presence of an oxidizing agent (like hydrogen peroxide) to adjust the final shade. Couplers help modify and enhance the hues produced by oxidative bases.

Effects on Hair Color:

• 13BIS is typically used to achieve intense and long-lasting shades. It can help refine and create specific color tones, especially when aiming for natural-looking shades or customized hues.
• It works particularly well for producing reddish or brown tones when used in conjunction with other dye intermediates.

Benefits:

• Improved Color Fastness: It contributes to better color durability and fade resistance over time, which is essential for maintaining vibrant hair color.
• Milder on Hair: Couplers like 13BIS can be less aggressive on the hair structure compared to some other oxidative dye ingredients, potentially making the hair coloring process less damaging.
