L-Erythrulose CAS 533-50-6

1. L-Erythrulose CAS 533-50-6 is a natural keto-sugar primarily used as a safe, non-toxic self-tanning agent in cosmetics, where it reacts with skin proteins to produce a temporary, natural-looking tan without UV exposure .
2. L-Erythrulose  offers a more gradual, even tan that lasts 2-10 days, helps avoid the streaking and drying effects of DHA, and is often combined with DHA for improved results .
3. High-purity L-Erythrulose is used in biochemical research to study metabolic pathways like the pentose phosphate cycle and as a building block in pharmaceutical synthesis .

1. Store L-Erythrulose CAS 533-50-6 in a tightly sealed container in a cool, dry place (2-8°C is recommended), protected from light .
2. Keep L-Erythrulose away from strong oxidizing agents; use spark-proof tools and explosion-proof equipment to prevent fire caused by electrostatic discharge .
3. Handle L-Erythrulose using appropriate personal protective equipment (chemical-resistant gloves, tightly fitting safety goggles) in a well-ventilated area, avoiding dust formation and contact with skin and eyes .

1. Isolate the spill area, eliminate all ignition sources, and wear full protective equipment including self-contained breathing apparatus before handling L-Erythrulose .
2. Absorb liquid L-Erythrulose with dry inert material like sand, collect using non-sparking tools into sealed, labeled containers for disposal, and prevent entry into drains or waterways .
3. Personnel cleaning L-Erythrulose spills must dispose of waste through a licensed chemical destruction facility or by controlled incineration with flue gas scrubbing, as discharge into the environment must be avoided .

1. L-Erythrulose CAS 533-50-6 is generally considered non-toxic, non-irritant, and safe for topical use in cosmetics, with labeling claims including biodegradable, natural, and non-carcinogenic . However, as a research chemical, it may be harmful if swallowed, inhaled, or absorbed through the skin.
2. L-Erythrulose is classified with GHS signal word "Warning" by some suppliers; under fire conditions, thermal decomposition produces toxic fumes including carbon oxides .
3. L-Erythrulose has a flash point of 179.4°C, is not classified as hazardous material for transport (DOT, IATA, IMDG), and has a shelf life of up to 3 years when stored properly .
