Research Activities by Lion Corporation Chemicals Division

When it comes to chemicals, product competitiveness relies on a manufacturer’s technological capabilities. Such capabilities will, in turn, drive business growth once they are successfully incorporated in new products. To make this happen, Lion Corporation Chemicals Division is undertaking research activities in the fields of synthetic chemistry, surface chemistry and chemical engineering, all of which serve as a basis of its product and technological development.

In synthetic chemistry, we are developing new high-performance functional materials that impose less environmental burden. By combining our elemental technologies in surface chemistry, namely, those related to washing, emulsification and dispersion, we provide immediate solutions customized to the specific needs of industrial users. In chemical engineering, we are aiming to achieve a productivity improvement as we work together with related manufacturing sites. Utilizing its technological development capabilities in the material science field along with its strong corporate brand as a leading company in terms of environmental friendliness, Lion provides wide-ranging industries with such products as oleo-chemicals, surfactants and other high-performance products.

Alkylene oxide addition polymerization technology

Lion’s proprietary technology precisely polymerizes ethylene oxide and other types of alkylene oxide by adding such hydrophobic fatty alcohols to eventually generate a variety of surfactants with unique properties. With regard to this technology, the Company received the 2005 General Award, which is the most renowned of the Japan Chemical Industry Association’s technological awards, for the development and commercialization of a new ethoxylation technology that utilizes complex metal oxide catalysts.

Product List

  • LEOFAT LA series

Esterification technology and separation and purification technologies

Using such vegetable oils as coconut and palm oils as raw materials and employing esterification as well as advanced fractional distillation processes, we are producing methyl esters boasting 99% purity, an achievement that makes Lion unique among domestic manufacturers. These high-purity esters, after undergoing sulfonation and amination, are used as ingredients in a variety of detergent and fabric softener products.

  • PASTELL series
  • LEOFAT series

Functional polymer design technology

We are providing products suited for a wide array of fields including paper processing, construction and cosmetics by employing molecular design technologies to create compounds based on such carboxylic acid-based polymers as acryl-based polymer as well as naturally derived polymers.

Spontaneous emulsification and cleaning technology

Particular surfactants are known to reduce the surface tension between washing fluid and machine oil attached to the surface of metallic parts to almost zero. Such surfactants can, therefore, cause “spontaneous emulsification,” in which emulsification takes place without the need to apply such mechanical force as agitation or scrubbing. Leveraging this process, we developed a cleaning technology that is excellent in removing grime, including the grease and other foreign substances that cling to precision equipment components after processing.

  • SUNWASH FM series

Micro-emulsion cleaning technology

By optimally selecting and formulating such agents as surfactants, penetrants and solvents, we have developed a technology of forming stable micro-emulsions in water. The penetrability and solubility of this micro-emulsion technology enables the cleaning of liquid crystal material sandwiched between two glass substrates only 3μm apart.

  • SUNWASH LH series
  • SUNWASH SS series

Precision cleaning technology

We have developed a detergent that optimizes the actions of alkalines and chelating agents while enhancing the detachability of abrasive agent particles and their zeta potential. Consequently, this detergent removes and prevents the redeposition of such micro-particulate grime as colloidal silica to hard disk substrates.

  • SUNWASH MD series
  • SUNWASH TL series

Carbon black dispersion control technology

This technology gives the customer a high degree of control over the dispersion of electro-conductive carbon black (CB) additives, including KETJENBLACK. In particular, such products as LEOPOUND, a resin compound, provide electro-conductivity with a lower volume of additives, owing to a polymer alloy technology that enables high CB dispersion. This technology has enabled us to produce LEOPOUND SHEET PC, a resin compound in sheet form that boasts superior surface flatness.

Wastepaper recycling technology

The De-inking process for paper recycling is often compared to doing laundry. Just like a detergent is used in doing the laundry, a de-inking agent is used in the paper recycling process. Just as Lion’s detergent products wash the dirt from cloth, its de-inking agents also removes ink from paper.

Product List

  • LIPTOL series

Photocatalyst technology (fiber processing)

Our photocatalyst, which is composed chiefly of porous silicate salt, possesses antibacterial and deodorizing effectiveness when exposed to light. While this material has drawn interest as an environmentally friendly material, applications have until now been limited to inorganic substances as it breaks down organic substances. However, we have used our composite compound technology to solve this problem, making this substance suitable for clothing, curtains and other fiber-related applications.

  • LIONITE PC series

Cement dispersion technology

Utilizing a polyacrylic acid based dispersing agent, our cement dispersion technology ensures that cement maintains an effective level of fluidity when pouring concrete. This agent simultaneously employs differing chemical structures to maintain stable and lasting dispersion. The agent is also available in a powdered form that adds no moisture to the cement when the concrete is being mixed and, therefore, does not reduce the durability of concrete

Product List

  • LEOPACK series

Cement / polymer composite technology

Addressing a weakness in cement materials, we developed an ultra-fine particle acryl polymer emulsion that features a core-shell structure that ensures superior cement dispersion. By facilitating the even dispersion of water, cement, aggregate and polymer, it counters concrete’s natural tendency toward brittleness and water-absorbency while preserving concretes strong points, including compressive strength.

  • LIPOTEX series

Adhesiveness improvement technology

We have developed another type of ultra-fine particle polymer emulsion to overcome the poor adhesiveness of newly grouted cement to hardened cement. This polymer emulsion features a unique level of adhesiveness due to a chemical modification made to the surface of the particles contained in the emulsion. It is particularly effective in securing in place new concrete that has been placed on the surface of hardened concrete and is useful in repairing deteriorated concrete structures.
