The isoflavone as a derivatives of flavone is colorless crystalline compounds. It acts on synthesis of fibronectine, collagen III, collagen I in human normal fibroblast by same biological activity to animal hormone. In this study, we tried to search and demonstrate system content rate of dermal translocation system for cosmetics using microemulsion containing isoflavone. The results of microemulsion stability test by centrifugation, storage in incubator and circulation chamber showed that separation of phase did not appear after 30 days. By the skin flexibility test, it has confirmed efficiency and effect as cosmetics materials. As the result, the microemulsion showed that skin flexibility factor improved up to 7.6%. We could confirm that O/W type microemulsion was stable system.

Microemulsion is stable to aggregation, sedimentation, fusion and has 3nm~200nm of particle size which is transparent and semitransparent. The isoflavone as a derivatives of Flavone is colorless crystalline compounds. It has similar basic structure to steroid materials which is hormone that acts to skin physiological phenomenon. On this study, we tried to search and demonstrate system content rate of dermal translocation system for cosmetics using O/W type microemulsion containing isoflavone. We manufactured O/W microemulsions by phase inversion emulsification method. It's was found that POE(20) monostearate with HLB value 14 caused microemulsion to be formed, which had 4nm~18nm of average diameter and 3nm~33nm of particle size distribution. Apparent viscosities of the microemulsions have increased in proportion to add surfactant dose.

Allylaliphatic carboxylate oligomers were prepared from polymerization giving allyl aliphatic carboxylates in the presence of potassium persulfate in methanol and the α-sulfonation of these allyl aliphatic carboxylates oligomers were carried by direct addition of dry sulfur trioxide. The dispersing performance of oligomer type anionic surfactants and SDS in the aqueous suspension of Fe2O3 and Tio2 particles were evaluated by particle size distribution and ξ-potential measurement. As results, the particles of Fe2O3 and Tio2 were flocculated by addition of small amount of oligomer type anionic surfactants and SDS, then the flocks redispersed by more addition oligomer type anionic surfactants and SDS. The dispersion and flocculation were observed in lower concentration range of oligomer type anionic surfactants than SDS.

Acrylic pressure sensitive adhesives of n-butyl acrylate, 2-ethyl acrylate, methyl acrylate, vinyl acetate, acrylic acid, acrylonitrile and 2-hydroxyethyl acrylate were synthesized and basic physical properties of pressure sensitive adhesives with increasing the contents of 2-hydroxyethyl acrylate were investigated. 2-Hydroxyethyl acrylates effects on glass transition temperature, viscosity, hardening time and peel strength. Glass transition temperature(Tg) decreased with increasing the contents of 2-hydroxyethyl acrylate. Viscosity and hardening time were increased with increasing the contents of 2-hydroxyethyl acrylate. On the other hands, peel strength increased with increasing the contents of 2-hydroxyethyl acrylate up to 6 wt% and the decreased at further higher contents of 2-hydroxyethyl acrylate. In peel test, interfacial failure was occured in 8 wt% and 10wt%.

Several instances of synergistic interaction have been identified between alkyl amine oxide and long chain fatty acohol polyethoxylates in various surfactant formulation. The purpose of this study was examined whether these benefits could be observed within the framework of generic hand-surface cleaning formulations. Comparative evaluation were also carried out to determine the performance characteristics of low-and zero-phosphate systems in which amine oxide and alcohol ethoxylates are used. Best cleaning was observed with 1:1 mixtures of the subject surfactants, but substantial improvements over fatty alcohol ethoxylate alone also were noted with formulations that contained lower ratios of amine oxide

The sodium α-sulfo fatty acid vinyl ester oligomers, which are oligomer type surfactants were prepared by polymerization with fatty acid vinyl acetate. The α-sulfonation of fatty acid vinyl ester oligomers were carried by direct addition of sulfur trioxide. The dispersing performance of oligomer type anionic surfactants and sodium dodecyl sulfate(SDS) in the aqueous suspension of iron oxide and titanium dioxide particles was evaluated by particle size distribution and zeta-potential measurement. As results, the particles of iron oxide and titanium dioxide were flocculated by addition of small amount of oligomer type anionic surfactants and sodium dodecyl sulfate(SDS), then the flocks redispersed by more addition of oligomer type anionic surfactants and SDS. The flocculation, redispersion process was observed in lower concentration range of oligomer type anionic surfactants than SDS. Especially, the dispersing action of sodium α-sulfo palmitic acid vinyl ester oligomer was better than sodium α-sulfo lauric acid vinyl ester oligomer.

Fluorescent anionic oligo surfactants were synthesized by the condensing products of long chain alkylvinylether-maleic anhydride cooligomers and resorcinol including dye structures. Their various surface activities and dispersing action were studied on the aqueous solution. These oligo surfactants exhibited a remarkable surface tension lowering property, lower foaming and a large dispersing action for the particles of α-copper phthalocyanine blue. Further it was ascertained that the binding of oligo surfactant onto the pigment surface caused the deviation towards lower wavelengths at the maximum fluorescent intensity as compared with aqueous oligo surfactant solutions, These surface active properties of the oligo surfactants may be attributed to rigid and hydrophobic structure of dye groups, besides surface-active groups of alkylether groups and carboxylic group of the anionic oligo surfactants.

The ultraviolet blocking agents used to skincare are largely classified ultraviolet scattering agent and ultraviolet absorbent agents. There are UVC, UVB, and UBA in ultraviolet ray(UV) showing shorter wavelength than visible light. Both visible light and UVA give rise to 1st dark-skinned phenomena. On exposure of the skin to UV, phenomena of skin variation are termed sunburn or suntan. There are chronic and acute adverse reactions in skin response to UV. The latter is caused by UVB, which has mainly effects on the skin. But lately due to destruction of ozone layer, UVA has more serious irritation on the skin than UVB. In this paper spectrometric properties of UV absorbent agents such as PABA, octyl-PABA, Urocanic acid, and 2-hydroxy-4-methoxy benzophenone in vitro have been investigate. As results, it was found that the three fomer were more suitable than the last. UV scattering measurements on the sample used inorganic pigments showed that pigments containing titanium dioxide had a better scattering effects than the inorganic pigments such as Fe2O3, Al2O3, etc.

As raw materials, the inorganic pigments, such as mica, talc and some metal oxides were mainly used in Make-Up cosmetics. Some other polymerics, organics and functional pigments were also used to cope with the various consumer's demends. Recently, excellent sliding, adhensivness, coverture and UV cutting properties were strongly required in Make-Up cosmetics. According to these demends, it needs to understand the functional properties of each pigment and consider the proper use for some purpose. And so, this report introduce the properties of inorganics, polymerics and functional pigments and their application fields for Make-Up cosmetics.

The synthesis of urocanic acid which was started D-fructose, and its alkyl esters, urocanic ethyl ester and urocanic isobutyl ester, were prepared by esterificated. Urocanic ethyl ester and urocanic isobutyl ester were insoluble in water and soluble most organic solvents (ethanol, benzene, toluene, pyridine, THF, DMF) which adds to their practical applicability, and absorb ultraviolet light of greater wavelength than the free acid and there by are more effective for shielding sensitive materials, including the humanbody, from the chemically most effective portion of the solar ultraviolet spectrum.
