Deoxyarbutin can effectively inhibit tyrosinase in the skin tissues, quickly and effectively make the skin white, and when you stop using the ingredient, the effect can still be maintained for nearly 8 weeks, and its effect is even correct. It is 10 times that of hydroquinone, 350 times that of �²-arbutin, and 38.5 times that of the currently popular �±-arbutin. Main Function: As a competitive tyrosinase inhibitor, deoxyarbutin can regulate the production of melanin, overcome pigmentation,lighten skin black spots, and has a rapid and long-lasting skin whitening effect. The inhibitory effect of deoxyarbutin on tyrosinase is significantly better than other whitening active agents, and it can show whitening and brightening effects with a small amount of use. Deoxyarbutin also has a strong antioxidant effect. Usage: Deoxyarbutin is a new generation of cosmetic brightening and whitening active agent, mainly used in advanced whitening cosmetics.It can effectively inhibit tyrosinase activity, regulate the production of melanin, overcome pigmentation,lighten skin black spots, and has a rapid and long-lasting effect of skin whitening effect.Deoxyarbutin also has a strong antioxidant effect.The inhibitory effect of deoxyarbutin on tyrosinase is significantly better than other whitening active agents.The whitening effect is 350 times that of arbutin, 150 times that of kojic acid, and 10 times that of hydroquinone.Compared with the former, it is safer High, more stable, not only non-toxic and non-irritating to the skin, but also easily absorbed by the skin. It can show whitening and brightening effects with a small amount of use. It is considered a very safe cosmetic whitening active agent.

Water Treatment DEHA is used in Water Treatment Chemical Formulations for controlling corrosion in boiler very effectively due to its property of oxygen scavenge scores over conventional hydrazine hydrate since it is far less toxic and meets the standard for disposal of blow offs without any difficulty giving good protection against corrosion at the same time. Polymerization DEHA's powerful free radical scavenging ability coupled with its moderate volatility and relatively low order of acute toxicity makes it an ideal "po Polymer "/ vapour phase inhibitor for olefins or styrene monomer storage & recovery system. Because of its capability of inhibiting polymerlzatlot the gas phase, DEHA is finding use as an in-process inhibitor for the production of styrene, divinylbenzene, butadiene, isoprene and other monorr containing a reactive double bond. â?¢ Photographic Chemicals DEHA has reducing property, so it is used as an auxiliary chemical photographic developer for instant colour photos. Also, DEHA is effective in stabilization of image and in the prevention of discolouration. Decolourisation Phenol and Phenolic antioxidants can be decolourised with DEHA. Inhibitors DEHA also can be used as a colour stabiliser of monoalkyl phenol. Silicon Rubber DEHA can be used as a raw material for the hardener of the Silicon Sealant and coating agent. Storage Can be stored and handled in equipment made of stainless steel of Type SS304 or SS316 or steel lined with glass, polypropylene or polyethylene Storage in mild steel equipment or containers is not recommended. DEHA drums should be stored in a cool and well ventillated area, away from sources of ignition. Forms two layers for concerntration from 33 to 87 wt %. Packing 25 kg, 180 kg net wt. in HMHDPE carbouys & drums . Health &Safety DEHA is irritating to skin,eyes and the mucous membrane. In case of contact,affected area to be washed with plenty of water for atleast 15 minutes. In case of inhaltion,victim should be moved to fresh air and oxygen should be administered. In case of ingestion,victim should be made to consume copious quantity of milk and water. Medical advice should be sought at once. Personal protective equipment should always be used while handling.
