ジャーナル フリーPermanent waves belong to quasi-drugs and function as wave-forming agents or hair straighteners. However, merely having these basic function is no longer sufficient to meet today's consumers' needs. The modern permanent waves must be mild to hair and skin, have little oder, easy to use and allow easy styling.
To develop products that will fulfill these needs, it is important during the formulation stage to use objective evaluation methods which correspond to a real situation. In this report, rapid and simple-to-use instrument evaluation methods for permanent waves based on thioglycolic acid will be presented. Determinations of the effectiveness of formulations, effects on hair and oder problems will be discussed.抄録全体を表示PDF形式でダウンロード (6641K) -

ジャーナル フリーSince the main purpose of using hair colors is to impart colors on human hair, the accuracy of color, the ease of use and safety are very important considerations. In this report, two types of hair colors including oxidative hair dyes and semi-permanent hair colors using acid dyes will be selected to explain the main functions and mechanisms of hair colors. The methods of evaluating hair dye performance and quality, design of formations and other techniques necessary for product developments will be de discussed. In addition, colors of Japanese hair and evaluation of hair colors for professional salons will be also discussed.抄録全体を表示PDF形式でダウンロード (1959K) -

ジャーナル フリーOpaque physical sunscreens, ie, those containing TiO2 (titanium dioxide) or ZnO (zinc oxide) are important for photoprotection in UVA range. However, little is known about relationship different shapes or sphere size and UVA protection efficacy. Therefore, we studied the UVA protective properties of TiO2 and ZnO with different shapes.
Absorption spectrum of dipersed materials showed that zinc oxides have a definite absorption peak at the range between 300 and 400nm, with the intensity observed in the order of flake>needle>bead in their shapes.
In proportion to spectral characteristics, Zinc oxides exhibited a high UVA protective capacity as measured by guinea pig PUVA method with a similar order of shapes in their intensity.
UVA protection capacity with flake zinc oxide for human skin revealed a dose-dependent increase which was well correlated with relative transmission at the UVArange when applied to epidermal sheet.
Flake zinc oxide also showed the most suitable balance for having higher UVA protective capacity and lower whity effect.抄録全体を表示PDF形式でダウンロード (5923K) -

ジャーナル フリーThis work has been carried out in order to clarify the distribution of metal elements in human hair, using atomic absorption spectroscopy and transmission electron microscopy. The transmission electron micrograph of the cross section of human hair without staining metal showed that the melanin granule and inter and beneath cuticular area was darkened as black shadow. Moreover, ICP analysis showed that some metals existed more abundantly in refined melanin granule than in whole hair. The metal content of black hair was two times higher than that of white one. For the hair samples treated with alkaline hydrogen peroxide solutions (pH; 9, 10, 11), the reducing agents of permanent wave lotions (acidic, neutral, alkaline) and concentrated formic acid, the remaining metal quantities were measured. The metal quantities eluted by the above solutions were also measured. The quantities of metals extracted by several bleaching solutions were small. This means that even in bleaching hair sample, the metals are still strictly combined to the melanin granule. In the case of treating with reducing wave lotions, the dependency of the ratio of extraction of metal to the pH of the solutions was slightly smaller than that of bleaching solutions. Treating with formic acid, Ca and Mg were completely extracted. From these results, it has been suggested that some metals exist more abundantly in melanin granule and the intercellular area than internal area of cortex cell.抄録全体を表示PDF形式でダウンロード (2816K) -

ジャーナル フリーEffect of various oil components, added to a model hair rinse composed of octadecyltrimetyl-ammonium chloride (OTAC), 1-hexadecanol (C16OH) and water, was studied in terms of influence on the gel structure by using cone and plate viscometer, differential scanning calorimetry and polarizing microscopy. Oil components with lower polarity (hydrocarbon, ester oil, etc.) caused decrease of the structural viscosity of the rinse and slight change of the DSC curve. However, oil components with higher polarity (fatty alcohol, etc.) showed opposite phenomena. Exceptionally, silicone oil (SI) did not change both the structural viscosity and the DSC curve. By all of these results, the gel structure of the hair rinse was found to vary by addition of oil components.
Effect of oil components on the performance of the hair rinse was evaluated in terms of the adsorption onto hair and the luster of hair. With regards to the total adsorbed amount onto hair, the oil components which did not change the DSC curve showd higher value than the oil components which changed the curve. On the other hand, silicone oil exhibited excellent effect on both hair adsortion and luster, In this study, it was suggested that the effect of oil components on the gel structure correlates with performance of the hair rinse. It was also found that the timing of oil components addition (standard method, post-addition method) has a significant effect on both the gel structure and the performance of the hair rinse.抄録全体を表示PDF形式でダウンロード (5515K) -

ジャーナル フリーIt is known that organic solvents in nail enamels can damage nails but the mechanism of the damage has not been reported in detail in the literature. In this investigation, our discovery of inter-cellular lipids in the nail suggests that there is a moisture-retaining function in the nail, similar to that of stratum corneum in the skin. The damage of the nails by organic solvents is found to be due to an adverse effect of the solvents on this moisture-retaining function. From the studies using electron scanning microscope, trans-electron microscope and DSC, it was discovered that the moisture-retaining function was more strongly dependent both on intercelluar lipids than natural moisturizing factor, NMF. This discovery implies that the damage by organic solvents on nail is not limited to dehydration effect, but more important, it is also due to the loss of the inter-cellular lipids by leaching effect of the organic solvents.
Furthermore, it was discovered that the damage on the nails by organic solvents was not only due to a reduction of the moisture-retaining function but also due to the loss of barrier function of the nail. Thus, a complete recovery of the nail from the damage of organic solvents is quite difficult because it is not only important to supply moisture and NMF. it is also important to supply the lipids to maintain the barrier function of the nails.抄録全体を表示PDF形式でダウンロード (7472K) -

ジャーナル フリーIt has been known empirically that the odor evolved from human hair and scalp is different from the odor from body or foot.
We tried to identified the volatile compounds evolved from human hair and scalp using headspace sampling method and extraction by acetone.
By the headspace method, over eighty of compounds were detected and almost thirty subsequently identified. The latter belong to various chemical classes such as alkanes, alkenes, alcohols, aldehydes, and acids. we tried to reconstitute of the odor according to the result of analysis and using the sense of perfumers.
Moreover, the changing of volatile compounds and increasing of scalp resident bacteriars during three days were investigated.抄録全体を表示PDF形式でダウンロード (442K)
