Papain is a natural enzyme, it is a kind of endopeptidase enzyme containing hydrosulfide group (-SH), and its molecular weight is 21000. It has strong ability of hydrolyzing protein, polypeptide, ester, acid amide and strong synthetic capacity which can combine protein hydrolyzate into protein substances.

it is essential for the plants natural defense against varmints.

Papain is an effective peel-off substrate for the renewal of soft skin. This makes the skin look fresh and younger after the treatment.

Application

● Cosmetics Industry：

Papaya enzyme acts on the aging stratum corneum of human skin to promote its decomposition, degeneration, skin rejuvenation and cell growth. The papaya enzyme hydrolyzate forms an amino acid derivative film on the skin surface to keep the skin moist and smooth. ; Papain is easy to form a complex with the copper ions in the melanin that forms the spots, reduces the formation of melanin and removes the melanin in the spots, and the tripeptide substance hydrolyzed by papain can directly inhibit the tyrosine activity that forms melanin and eliminate Free radical function, so as to achieve the effect of whitening and removing spots

● Personal Care Industry：

Used in soap, soap, detergent, washing powder, hand sanitizer, etc. After clothing is contaminated by blood stains, milk, juice, soy oil, etc., it is generally difficult to remove these stains with ordinary detergents. If the protease is added to the 

detergent, sweat stains and blood stains can be easily removed, with strong detergency, sterilization and disinfection, and safe and secure.

Application concentration

● The reaction temperature is 50-55 ℃, the concentration of material is 25 to 50%, pH 6-7, enzyme dosage of 0.1 to 0.3% (in material weight), reaction time is 6 to 8 hours. Temperature, pH, added, reaction time can make appropriate changes based on different substrates.

● The optimal dosage of enzyme added production should follow  the specific produce circumstances, please feel free to email us or call us.

Toxicology
