1. In skincare
Hydroquinone CAS 123-31-9 is a common ingredient in skin - lightening products. Hydroquinone works by inhibiting the enzyme tyrosinase, which is involved in the production of melanin (the pigment that gives skin its color). Hydroquinone CAS 123-31-9 helps to reduce hyperpigmentation such as age spots, melasma, and post - inflammatory hyperpigmentation.
2. In photography (although less common nowadays)
Hydroquinone CAS 123-31-9 was used as a developing agent in traditional black - and - white film photography. Hydroquinone helps to convert the latent image on the film (formed by light exposure) into a visible image.
3. In the chemical industry
Hydroquinone CAS 123-31-9 is used as an intermediate in the synthesis of various organic compounds, including some polymers and pharmaceuticals.
Packed in 25 kg per drum or based on customers' requirements.
1. Keep Hydroquinone in a cool, dry place. Temperatures around 2 - 8℃ (36 - 46°F) are ideal. Heat and moisture can cause Hydroquinone to oxidize and degrade.
2. Store Hydroquinone CAS 123-31-9 in a tightly sealed container. Exposure to air can lead to oxidation, Hydroquinone can change Hydroquinone properties.
3. Protect Hydroquinone CAS 123-31-9 from light. Hydroquinone is photosensitive, so storing Hydroquinone CAS 123-31-9 in a dark container or a shaded area helps maintain its stability.
4. Keep Hydroquinone away from strong oxidizing agents and bases, as these can react with hydroquinone.
