What is poly-gamma-glutamic acid?
poly-γ-glutamic acid(γ-PGA) is a natural, high molecular and linear polypeptide which mainly produced from microbes, such as Bacillus species.
The cross-linking of γ-PGA
Hydrogels of γ-PGA can be prepared by chemical (PEG, polysaccharide etc.) and physical(UV, gamma irradiation, electron beam etc.) cross-linking process
ebCL Technology
Through Rabe Co., Ltd. proprietary technology ebCL, Obsess forms a cross-linked product through the physical reaction of electron beams without adding chemicals, so there is no risk of residual chemicals.
Electron-beam induced cross-linking(ebCL)
- - Electron-beam is a kind of β-rays emitted by linear electron accelerator.
- - Linear electron accelerator is energy effective and can be controlled by on-off of electric power.
- - The electron-beam cross-linking is the interconnection of adjacent long molecules with networks of bonds induced by free radicals from water and electron-beam reaction.
- - Electron-beam processing is used in the fields of semiconductor, polymer, sterilization, nanotechnology etc.
Chemical free
The Obsess is fabricated by physical reaction of electron-beam only and there are no risks of residual toxicity.
Texture and Structure of OBSESS HYDROGEL
-
Homogenous of texture
The electron-beam crosslinking process of OBSESS HYDROGEL is controlled by mechanically and it can imbody a high homogenous of texture.
-
Structure of OBSESS HYDROGEL
OBSESS HYDROGEL reveals a multi-baglike structure that is capable of enhanced absorption of moisture because of the cross-linking of the peptides.
Obsess advantage
- activates a natural moisturizing factor, such as pyrolidone carboxylic acid(PCA) and/or urocanic acid.
- offers an improved visco-elasticity and flow characteristics
- OBSESS HYDROGEL can reduce the swelling, embossing and lumpy problem of existing filler.
Cytotoxicity , Inflammation and immune reaction
The in vitro cell test (WST assay) confirmed that OBSESS HYDROGEL showed no cytotoxicity.
