A new method, a combination of the tape-stripped and paper-absorbent methods, was developed for measuring the distribution of peroxide and skin surface lipids on their depth in human stratum corneum. Peroxide lipids were shown to be produced not only in the top layer of the stratum corneum in the skin of people not exposed to sunlight but in the deep layer as well. Their compositions were correlated to those of skin surface lipids. Peroxide lipids in the outer layer were more easily produced than those in inner layers, possibly due to higher squalene content in the outer lipids. The removal of peroxide and skin surface lipids from the stratum corneum was also conducted and the washing properties were noted to differ. Peroxide lipids not only in the outer layer but also in the inner layer could be washed away while washing removed skin surface lipids only from the top layer. The addition of a cleanser enhanced removal efficiency.The removal efficiency of three surfactants differing in hydrophilic groups, i.e. phosphate, sulfate and carboxylate groups, was assessed. The phosphate type surfactant was found more capable of removing skin surface lipids in the stratum corneum.Based on the present results, an ideal cleanser should wash away peroxide lipids situated deeply within and harmful to the skin, but only skin surface lipids which function as a surfactant barrier.

Docosahexaenoic acid (DHA) and icosapentaenoic acid (EPA) are valuable nutrients because they have important roles as the constituents of structural lipids in the nervous tissues of human brain and retina. In addition, DHA, EPA and other omega-3 fatty acids are important factors in the prevention of several human diseases. Fishes have been the dietary source of these fatty acids and they originate from the marine microbes upon which the fishes feed. Therefore, these marine microbes cultured under control could be utilized as alternative source of the omega-3 fatty acids.Marine microalgae are rich in DHA and EPA. However, very few species of freshwater algae contain significant amounts of these compounds. The marine unicellular alga Isochrysis galbana is well known as a source of such fatty acids and this species has been used extensively as a food source for aquaculture. The advantage of the marine microalgae such as I. galbana over other microbes as sources of polyunsaturated fatty acid is that this alga may be grown photosynthetically using carbon dioxide as the sole carbon source and seawater as a source of minerals.In this paper, we focused on the production of marine microalgae as an alternative source of polyunsaturated fatty acid. We have screened a number of species of marine microalga specifically for their ability to produce DHA and EPA and have optimized the growth conditions for I. galbana. The utilization of microalgae as feed for cultivation of rotifers is also reported. Moreover, the applications of genetic engineering for EPA production are also demonstrated.

The characteristics of soaps prepared from waste edible oil (oils before desgarding used frying oils at home or school refectory) or soybean and rapeseed oils with different degrees of thermal oxidation were investigated. Thermal oxidation oils were prepared by heating in a fryer (National NF-F 100) at 180°C for 20 and 40 h. Waste edible oil collected from home and school was combined. Preparation method of soap, method I. Soaps from fresh and thermal oxidation oils were prepared by heating at 90°C for 3 h with mixtures of 100 g fresh or thermal oxidation oils, 25 g potassium hydroxide and 300 g water. Method II. Soaps from waste edible oil were prepared at room temperature for. 30 d with mixtures of 2500 g waste edible oil, 450 g sodium hydroxide, 2000 g water (added hot water of 500 g every third day) and one cup of left-over rice. They were stored in beakers at room temperature.Anisidine, carbonyl and peroxide values and content of oxidized fatty acids (fatty substances insoluble in petroleum ether) in soap were determined with fatty acids isolated by acidifying the mixture with hydrochloric acid.Anisidine and carbonyl values of soaps prepared from thermal oxidation oil were markedly lower than those of thermal oxidation oil. Anisidine and carbonyl values were much higher in waste edible oil soap than in waste edible oil. Oxidized fatty acid content in each soap was similar to that of thermally oxidized waste edible oils. Increase in anisidine, carbonyl and peroxide values was observed during storage.

Skin surface is covered with very thin lipid film called as skin surface lipids. Skin surface lipids are the mixture of sebum originated from sebaceous gland and epidermal lipids. Epidermal lipid is the minor component of skin surface lipids and occupies less than 5 % of skin surface lipids. However, the epidermal lipids, especially ceramide, play an important role in water barrier function of the skin.

The influences of six representative surfactants on hair and the scalp were investigated under various conditions such as : irritation, protein denaturation, sorption onto commercial hide powder or keratin powder, change in turnover time of the stratum corneum, dandruff and disintegration of the cuticle.1. Influence of surfactants on scalp.Although the cumulative irritation test, 48-hour closed patch test, and immersion test were performed to assess the irritating effects of surfactants, the results did not agree with each other. The immersion test, which makes essentially the same use of surfactants, gave results in close agreement with those for sorption of sufactants or protein denaturation by surfactants.Amounts of surfactants sorbed by hide powder.Irritation score of immersion test : r=0.671.Amounts of surfactants sorbed by keratin powder.Irritation score of immersion test : r=0.930.Per cent denaturation of OVA by surfactants.Irritation score of immersion test : r=0.880.Turnover times of the stratum corneum due to the surfactants were found to follow the order, AMT≤AGS≤L-Soap≤AP<LS≤ES.Examination of the amounts of dandruff as observed when using AMT shampoo and ES shampoo, each with a different effect on the turnover time of the stratum corneum, showed the amounts to differ remarkably according to the surfactant used.2. Influence of surfactants on hair.The extent of disintegration of cuticle by a surfactant supersonic treatment was found to have the following order : AMT≤AGS≤AP≤ES<LS<L-Soap.Based on the above results, AMT can be a good surfactant as a detergent for the hair and scalp.

Properties of N-acyl-N-methyltaurate(AMT), including surface active properties, cutaneous effects, influence on hair, and application to liquid type hair shampoo, are reviewed.It has been found that AMT exhibit considerably high safety on skin in comparison with typical surfactants. As the result of cutaneous effects, the reduction of the amounts of dandruff was observed when using AMT shampoo.In addition, AMT shows weaker action on the desintegration of hair cuticle.Consequently, AMT can be a good surfactant as a detergent for the hair and scalp(skin).On the other hand, cutaneous effects and physico-chemical properties of anionic/amphoteric surfactants mixed system, were investigated.It has been found that these physico-chemical results were in good correlation with those pbtained by cutaneous effects. The synergistic reductions in cutaneous effects were observed as well as physico-chemical results.These findings have promoted the development of hair shampoo composed of AMT.

Free iron could easily be chelated with phosphate moiety in biomembrane surface and reduced enzymatically by certain membrane components or non enzymatically by ascorbate.A model membrane lipid peroxidation induced by iron-adriamycin or iron-glycated peptide was discussed. Most probable active species for their lipid peroxidations could be iron oxygen complexes, such as FeV= O and Fe IV=O type compounds. Heme-compounds, hemoglobin, cytochrome P-450 and hematin could mainly act to decompose lipid hydroperoxides to their corresponding alkoxy radicals and hydroperoxy radicals, by which lipid peroxidation should be promoted.
