Application in cosmetics

1. Skin care product
Chitosan has good whitening effectiveness, which could penetrate into skin hair follicle eliminating melanin and fleck caused by microorganism accumulation.

2. Cosmetics
Chitosan has the effect of delaying senescence and improving cosmetic result.

Japan has developed the technique of manufacturing chitosan micro powders of 12 micro average particle size. Through constantly exploration and practice, Korui has made out chitosan micro powders of 5 micro average particle size, which could be widely applied in cosmetics.


Korui Biotech is not a supplier of chitosan or chitin material, but a supplier of low-molecular-weight (LMW) chitosan and specific chitosan derivatives. Base on our intensive research and numerous animal tests for more than 10 years, it is confirmed that low-molecular-weight chitosan has very good antibacterial effect and immunity enhancement than either high molecular weight or oligo-chitosan (MW < 5000). Our product is fabricated by physical methods and in the form of fine powder. Such product has high thermal stability and moisture-resistant. We have two type of low-molecular-weight chitosan products, one is water insoluble and the other is soluble. low-molecular-weight (LMW) chitosan of Korui can be used as a feed additive for pigs, chicken, and cow, fish and many other types of animals. It is very effective and the cost is minimum. Presently we supply two major products for the use in pig industry, aquaculture industry and poultry raising. 1.Low-molecular-weight chitosan (KR 901) for animal feed, this product is water insoluble but soluble in dilute acidic solution; for pigs and poultry Dosage of KR901 for pig is as follows: 50 g/T for piglet’s feed, 80-100 g/T for sow’s feed, 20-25 g/T for feed of medium and big pig Dosage of KR901 for poultry is as follows: 20-30 g/T for feed 2.Low-molecular-weight chitosan (KR902) for aquatic feed, this product is water soluble. Dosage of KR 902 for aquaculture is as follows: 20-25 g/T, independent of type of fish, shrimp of others. This product can also be directly disolved in water to make dilute chitosan solution, and then spray on water area. It is especially useful for aquatic seedling.
