To prevent contamination by Campylobacter jejuni during chicken carcass processing, the effect of emulsifiers on C. jejuni inoculated on chicken skin was investigated using confocal laser scanning microscopy. Among the 8 emulsifiers (SWA-10D, L-7D, M-7D, S-1670, L-1695, P-1670, polysorbate 20, polysorbate 80) tested for antimicrobial activity by the paper disk method, 4 emulsifiers (L-7D, L-1695, polysorbate 20, polysorbate 80) were screened further. Emulsifier L-1695 showed the largest clear zone at a concentration of 200 mg/mL. The 4 emulsifiers subjected to primary screening were screened for heat and pH stability. In the contact surface test, emulsifier L-1695 showed the lowest log CFU/㎠ value on both stainless steel and ceramic surfaces. When emulsifier L-1695 was applied via general and electrostatic spray methods, the number of C. jejuni entrapped inside chicken skin follicles was significantly reduced in both methods. In conclusion, the emulsifier L-1695 could be employed as a microbial detachment agent in the chicken carcass processing industry.

To enhance the cleaning and sterilization effect of cooled electrolyzed acid water on lettuce, several kinds of polysorbates were used at various concentrations in immersion washing process. In case of the treatment containing polysorbate 20, coliform count of lettuce was reduced to about 1/40 level of that in non-treated lettuce. The treatment containing polysorbate 60 did not show a significant sterilization effect. Otherwise, the total and coliform counts of lettuce during immersion in electrolyzed acid water containing 1 ppm of polysorbate 80 was reduced to about 1/300 and 1/1,700 level of those in non-treated one. And, the changes of ORP(oxidation-reduction potential), pH and color value of lettuce in electrolyzed acid water containing 1 ppm of polysorbate 80 were not quite different during 60 min. immersion, but HCIO content decreased from 10.28 ppm to 8.51 ppm after 20 min. immersion. Also, total and coliform count of lettuce immersed in electrolyzed acid water containing 1 ppm of polysorbate 80 was lower to about 1/1,800 after 20 min. and 1/5,550 after 30 min, compared with non-treated lettuce.

Recently inside nano liposome particles or nano-emulsions which contain tough-melting physiology activity materials or the coefficient of low organism utilization promote the coefficient of organism utilization, so this part has been studied a lot because they can absorb selectly cosmetics, specially physiology activity materials, into the skin. Also, in particle size, cells interstitial lipid interval are 30~50nm, so nano-emulsions that the size is similar to 30~50 nm are made to study for absorbing quickly into the skin. And transparent skin which contains oils in common skin lotion dosage form has become the center of public interest. The used nano-emulsions in this study were unsaturated lecithin/co-surfactant! ethanol/ oil / water. And polysorbate 20/ polysorbate 80/ Dicetyl phosphate/hydrogenated .caster oil/ isoceteth-20/SLS were used in co-surfactant. The used oils were cyclomethicone and caprylic/capric triglyceride. The manufacturing process was that microfluidizer was fixed in 1000bar and transit times were changed from 1 to 10 times. From transparency and particle size, the transparency sequence was SLS> polysorbate 20= polysorbate 80> isoceteth-20> dicetyl phosphate >hydrogenated caster oil and the particle size was small. Specially cyclomethicone nano-emulsions, when we made unsaturated lecithin /SLS /ethanol/water/cyclomethicone, cyclomethicone 5％ was good for transparency. And 20％ of this was used for making transparent skin toner in common skin dosage form.

Cellolose nanoparticles loaded with retinyl palmitate were prepared by modified spontaneous emulsification solvent diffusion method. We used polysorbate 20, polysorbate 60, and PPG-26-Buteth-26/PEG-40 Hydrogenated castor oil as dispersion medium. The optimum condition for particle size of cellulose nanoparticles was 1w/v% ethyl cellulose with, 3w/v% polysorbate 60 solution. And The optimum condition for leading amount of retinyl palmitate of cellulose nanoparticles was 2w/v% ethyl cellulose with 1w/v% polysorbate 60 solution. Also, we found that this optimum condition can be applicable to other active compounds.

Nanoemulsion is an emulsion with a particle size of about 20 ~ 200 nm and has the advantage of having a transparent or translucent appearance and improving the skin permeability of an effective material with a small particle size, so it is applied in various fields. In this study, eight oils with different types of HLB and 16 oils with different types of required HLB were selected to investigate the effect of the required HLB and the type on the formation of nanoemulsion. The surfactants used at this time were Polysorbate 60 (HLB 14.9), Sorbitan state (HLB 4.7), PEG-60 hydrogenated castor oil (HLB 14.0), which were mixed with Polysorbate 60 and Sorbitan state, fixed with HLB 14.0, and Polysorbate 60 and PEG-60 hydrogenated castor oil, respectively. The formation of nanoemulsion was different depending on the type of oil, and oil with an ester structure showed a relatively excellent nanoemulsion formation ability. In particular, it was confirmed that a stable nanoemulsion was formed without a significant change after Cetyl ethylhexanoin was produced in a small size of 40 nm or less on average. In addition, it was found that using a mixture of Polysorbate 60 and Sorbitan stearate has a superior nanoemulsion formation ability than using PEG-60 hydrogenated castor oil or Polysorbate 60 alone.

The combined use of indium and polysorbate 20 (Tween 20) was considered as a new inhibition technique for zinc corrosion. Zn and Zn-In alloy coatings were prepared by electrodeposition and their morphology and composition were characterized by scanning electron microscopy (SEM) and inductively coupled plasma atomic emission spectrometry (ICP-AES). The corrosion inhibition effect of indium and Tween 20 on zinc was investigated by polarization curves and electrochemical impedance spectroscopy (EIS). The corrosion inhibition efficiencies obtained from Tafel and EIS analyses are well in agreement. Zinc corrosion can be inhibited to some extent by the individual use of indium and Tween 20 and higher corrosion inhibition efficiency can be obtained by the combined use of indium and Tween 20.

The rheological properties and surface tensions of polymer solutions and polymer-surfactant mixed solutions were investigated. The polymers used in this study were a homopolymer of acrylic acid crosslinked with an allyl ether of pentaerythritol, an allyl ether of sucrose, or an allyl ether of propylene (CARBOMER), acylate/C10-30 alkyl acylate crosspolymer (AAAC), and ammonium acryloydimethyltaurate/VP copolymer (ADTV). A solubilizing agent PEG-40 hydrogenated castor oil (HCO-40) and an emulsifying agent polyoxyethylene (20) sorbitan monostearate (POLYSORBATE 60) made the micelles intervening between AAAC polymers, resulting in the increase of viscosity. However, HCO-40 made this behavior over the wider range of surfactant concentration than POLYSORBATE 60. From the view point of surface tensions in the same range of surfactant concentration, AAAC/HCO-40 solution showed the area of increasing surface tension with surfactant concentration in contrast to the AAAC/POLYSORBATE 60 solution showing no increasing area.

In this study, the mechanism on the phase behavior of polysorbate nonionic surfactants was investigated. In the ternary system containing water, hexanol as a polar oil and surfactant, the phase behaviors ranging from micellar region to occurrence of liquid crystal phase were observed by crossed microscope. As results, fine mosaic texture of liquid crystal phase and other phases were examined in the range of 20~70 wt%. This range if thought to give information about the basic data for the formulation of more stable emulsifying systems or dispersed systems. According to the alkyl chain length, three phase region diminished, whereas two phase range increased without an observation of the anisotropic liquid crystalline phase.
