Turmeric contains curcumin, which can react with certain substances, including detergents, leading to color changes. When turmeric stains are soaked in detergent, the surfactants can help break down the oils and pigments, potentially lifting the stain from fabrics. However, the effectiveness may vary depending on the type of detergent used and the fabric's material. It's essential to treat turmeric stains promptly for the best results.
It is because the turmeric contains a compound called cucumine.cucumine reacts with the fatty acid in the soap/detergent and thence the color of the combination changes to red.
Turmeric stains turn red when washed due to a chemical reaction involving the curcumin pigment in turmeric. When turmeric comes into contact with alkaline substances, such as soap or certain detergents, the pH change can alter the structure of curcumin, causing it to shift from its original yellow color to a reddish hue. This phenomenon is often more noticeable on certain fabrics or surfaces.
The red color observed when turmeric stains interact with detergent may be due to the detergent breaking down the chemical structure of the turmeric molecules, causing a change in their absorption properties. This results in the turmeric shifting from its characteristic yellow color to a reddish hue.

To dye fabric red with turmeric, start by preparing a dye bath by dissolving 1-2 tablespoons of turmeric powder in a pot of water and bringing it to a boil. Before dyeing, pre-soak the fabric in a mixture of water and vinegar to help the dye set. Once the dye bath is ready, add the pre-soaked fabric and simmer for about 30 minutes, stirring occasionally. After achieving the desired color, rinse the fabric in cold water until the water runs clear, then let it dry.
