Production of products without harmful microorganisms It is possible by sterilization of gamma rays.

Irradiation of Cosmetics

  • Production of finished products without microorganisms by sterilization of natural raw materials
  • Sanitization of herbal ingredients, processing of contaminated containers, various packaging materials and raw materials
  • Reliable sterilization (prevention of secondary contamination) with fully enclosed sealing structure
Using gamma rays is the development of new clean products.

Disposable products such as Oriental packs and Hwangto packs, which are free from harmful preservatives and preservatives, are used to produce clean, natural products without microorganisms.

It is top quality of the product to be operated and recommended by overseas buyers

Brushes, containers, and wigs made of animal hair are most likely to use gamma rays and will simplify quarantine for exported products.

Sterilization from raw materials to finished products is possible.
  • Production of high-value-added products - Reduction of chemical preservative added to the skin or production of fragrance using gamma-ray
  • Decolorize botanical extracts and improve function
  • Improving the moisturizing effect of raw materials such as cellulose (CMC)
  • Application by change of physical properties of starch, gelatine, saccharides, polyethylene glycol (PEG), etc., development of new material: Polymerization

It is fully realized in one day by using specific microorganisms, ordinary bacteria, fungi and other microorganism sterilization, gamma ray facilities

Irradiation of Pharmacetical

Gamma ray irradiation method is the most reliable quality process for microbial sterilization from raw materials to finished products

Quality control
  • Minimize changes in product variability, nutrient breakdown, potency and content.
  • It is possible to produce products that do not contain preservatives or minimize its content.
  • There is no burden on the manufacturing schedule with about 24 hours processing process.
  • It can be completely sealed to prevent secondary contamination.
  • The center of the raw material container and microorganisms inside the pills are completely sterilized.
Processing Advantages
  • Gamma rays penetrate into the inside of the product, enabling uniform and complete processing
  • It is cold sterilization method that does not cause impact, pressure, temperature, moisture factor.
  • It is a safer, cleaner and less hazardous residue than other methods of sterilization.
  • Sterilization process Reduction of investment cost
  • Environmentally friendly products can be produced and developed (preservatives, reduced use of preservatives and no use)
  • Reduce manpower and time due to normal sterilization of manufacturing process
Using Product

Finished products, raw materials, oriental raw materials, containers, packaging paper, etc.

Polymer material

Polymer materials such as rubber or synthetic resin The properties change when irradiated.

Improvement of physical properties of polymer materials, development of new materials is possible by irradiation of gamma rays.

Applying technology
  • There are large changes of branches, polymerization, GRAFTING, crossing, and decomposition.
  • Polymerization: small molecules connected to form large molecules
  • Grafting: the reaction of polymeric functional groups to ionize and branching
  • Cross-linking: the reaction of neighboring molecules to each other
  • Decomposition: In contrast to synthesis, large molecules break into small molecules
Advantages of Gamma Irradiation
  • Polymer crosslinking at low temperature without applying pressure
  • New products can be made more diverse than conventional chemical methods
  • Produce reproducible products with only the dose without additives
  • Simple curing process and speed of composite material is fast.
  • Polymer switches, latex manufacturing, materials for aviation and marine and sporting goods, hydrogels
  • Latex condoms and gloves, heat shrink tubing, wood plastic composite production, building materials
  • Development of tiles, new materials, and textile remobilization using waste tire

Experimental Supplies

Experimental Supplies01

Petri dish, disposable pipette tip, sterilization filter, aseptic gloves, aseptic, aseptic, etc.

Gamma-ray sterilization method can increase the completeness of experimental supplies.

Advantages of Gamma Irradiation
  • Secondary contamination does not occur because it is wrapped in finished product.
  • Continuous mass sterilization process is possible.
  • It is a sterilization method with a high preference for buyers for export products.

Experimental Supplies 02

The birth of sterilized animal feed with minimal nutrient destruction

Disadvantages of high pressure steam sterilization / EO gas sterilization
High pressure steam sterilization
  • Pelletized feed curing
  • Poor growth of young animals
  • palatability or component change occurred
EO gas sterilization
  • The sterilizing effect is insufficient.
  • Disintegrate nutrients such as vitamins and amino acids.
  • toxic problems caused by residual gas
  • A decrease in birth rate is reported.
Only the gamma sterilization method is available in a fully packaged state.
The microorganisms contaminated to the inside are completely killed, and it is born as an aseptic feed.
LAB Animals
Advantages of Gamma Irradiation
  • Protein is almost unchanged.
  • Amino acid content is almost unchanged.
  • Vitamin content breakdown is less than other sterilization methods.
  • The growth condition is the best.
  • Sterilization is possible in the state of finished product.
  • The shape of the feed does not change.

01Use in aseptic packaging and containers production industry

With the introduction of HACCP, which is a food intensive care standard for food, the process of sterile packaging during the food process is considered very important.

02Used for pet food and fish feed

Feeds can cause contamination of various germs and pathogens and parasites. This is not a problem, but a reality that can be transmitted to people through infection routes. So the US FDA is using gamma sterilization technology to manage the infectious pathway of acquired infectious agents.

03Use for quarantine items

The permeability of gamma rays is attracting attention as a quarantine treatment technology in international trade. It is used as a replacement technology for insect pests, germs and molds and chemical quarantine methods in natural fiber materials, dolls, toys.

04 Used in agricultural gardening goods

The Netherlands and other European countries, It is mainly used to prevent insect pests and larvae, bacteria and fungi that are polluted inside, and to prevent weed germination. It is used for agricultural irrigation mats, flower pots, pepper supports, pots, beehives, and seedlings

05Preservation of cultural properties

Using gamma ray technology for archival preservation of ancient documents and wooden cultural property.

06Coloring of jewels and glass

When gamma rays are applied to glassware, artificial insemination and artificial accessories, coloration of various concentrations is created and various products can be produced.
