ジャーナル フリーTwo types of new water-in-oil (w/o) type emulsification techniques were described in this review. The first, stable W/O-type emulsion could be prepared by the using gels formed between nonionic surfactants and aqueous solutions of amino acids. The gel can only be obtained with a fluid nonionic surfactant which has lipophilic properties and a specific orderly lamellar structure, and amino acids or their salts. The gel was capable of incorporating substantial amounts of water, resulting in the formation of a stable W/O-type emulsion.
The second, much stable W/O-type emulsion could be also preoared by an inclusion compond consisting a nonionic surfactant and organophilic montmollironite (Or-Mon). This compound (S/Or-Mon) swelled in oils such as liquid paraffin, resulting in the formation of a gel. When water was added further to a rapidly stirred oil gel, a stable W/O-type emulsion was obtained. In this system, S/Or-Mon shoud be function as a W/O-type emulsifier on the water/oil interface.抄録全体を表示PDF形式でダウンロード (2228K) -

ジャーナル フリーRecently, the world has been changing rapidly from the stand point of major changes in demographic society, environmental attitudes and judgements concerning the worth of things.
In this context, we companies must develop appropriate new cosmetic products using new materials and technology. Those new products should be made so as to be acceptable to consumer and market. Thus, developers need ways of measuring the potential of new products and wide technology.
In this paper, a case study is presented describing developing processes with respect to a new make-up Foundation we have formulated.抄録全体を表示PDF形式でダウンロード (1849K) -

ジャーナル フリーWe investigated age differences of various parameters for hair and scalp skin in 153 healthy volunteers (13-69 years old, _??_: n=49, _??_: n=104).
Age differences were showed clearly in some parameters that were (1) cross sectioned area (_??_ _??_) (2) water content (_??_) (3) cystine content (_??_) (4) contents of trace elements (Ca) (_??_)- as for hair shaft, and (5) sebum content (_??_ _??_) (6) stratum corneum cell area (_??_ _??_)- as for scalp skin.
Parameters (1), (2), (3) and (5) decreased with age, and (4) and (6) ncreased with age.
Many relationships among various parameters were found by means of multi value analysis of the experimental data.
Some relationships suggested that hair follicle G6PDH activity and cystine content of hair shaft, played important roles in formation of hair structures and physical properties.
And, polar lipids contents of hair were found to decrease with damaging of hair.抄録全体を表示PDF形式でダウンロード (666K) -

ジャーナル フリーThe objective of this study is to develop a novel UV absorbent which has sufficient efficacy to prevent human skin from sun-burning or sun-tanning, and is bio-compatible with human skin.
α-Dehydro amino acid derivatives were synthesized. To investigate the usefulness of these compounds as UV absorbents for sunscreens, UV absorbance and solubility in various solvents were measured.
Among these compounds, 4-(3, 4-Dimethoxyphenylmethylene-2, 5-dioxoimidazolidine-1-propionic acid 2-ethylhexyl ester (DH) and N-Benzoyl-α-dehydrotyrosine 2-ethylhexyl (DT) have excellent properties as UVA absorbent and UVB absorbent, respectively.抄録全体を表示PDF形式でダウンロード (933K) -

ジャーナル フリーThe relation between the wind and the skin physiology was examined as part of the research concerning the environment and the physiology. As a constant wind was exposed to the face, the change of the skin physiological parameters were examined.
Subjects consisted of 8 healthy men (24-44yr). Subject's face were exposed to various wind (air velocity 0, 1.0, 2.0, 3.0, 4.0m/sec) at environmental condition of 25°C and 60% R. H. Also, wind (2.0m/s) was exposed at the different air temperature, i.e., 15, 25 and 30°C. Measurement items were skin temperature at forehead, cheek, nose and chin, hydration state of cheek, replacement sebum level of forehead, observation of skin surface and psychological effects.
The skin temperature has decreased intentionally by the wind exposure. The hydration state has also decreased by wind exposure. However, the relation was not admitted in level of air velocity and the decrease of hydration state. The replacement sebum level was showed low value by wind exposure. Morever, the correlation between skin temperature and psychological response (comfort sensation and thermal sensation) was found.
This study showed that wind influenced on the skin temperature and the other skin physiological factors, i.e. the various skin functions were discerned by wind, and that wind influenced on the comfort and thermal sensations.抄録全体を表示PDF形式でダウンロード (2326K) -

ジャーナル フリーMany Japanese women are concerned about the darkness of their skin. However, the treatment for skin darkness have not, until now, been thoroughly tackled because of vagueness of skin darkness.
Our study is aimed at clarifying skin darkness.
Firstly, a questionnaire on the awareness of skin darkess was conducted on 975 Japanese women to determine the average consumers interpretation of “darkness”. Secondly, evaluations on “subjective” and “objective” darkness in female faces were simultaneously conducted on 167 women with the aim of grasping the relation between subjective and objective darkness in the same person. Finally, components of “objective darkness” were examined, and the following information was obtained.
The awareness of skin darkness among Japanese women can be expressed by two factors: a “blackish” factor, and a “drooping” factor, associated with morphological elements.
The evaluation of darkness requires the specification of facial sites because degrees of agreement between subjective “darkness consciousness” and objective “darkness impression” are different according to the sites.
Components of darkness impression are color tone and morphology. A moderately deteriorated morphology in particular was assumed to have influence on the darkness impression similar to the color tone.抄録全体を表示PDF形式でダウンロード (3349K) -

ジャーナル フリーWrinkle formation is associated with alteration in the extracellular matrix, collagen and elastic fibers in the dermis of the skin. Cross-linking of collagen is a typical alteration and increases with aging. Glycation (nonenzymatic glycosylation) is the so called Maillard reaction and is a posttranslational modification of proteins resulting from reactions of glucose with amino groups in protein. Collagen cross-linking is also caused by the Maillard reaction.
In this study, 10 harb extracts used in the prescriptions for wrinkle removal in ancient Chinese medical literature, were selected and studied for their capacity to collagen cross-linking formation induced by the Maillard reaction. Bukuryou and Byakuren were the most effective inhibitors and Byakuren showed the same effect with aminoguanidine as a positive control. Byakuren also inhibited the formation of fluorescent materials due to the Maillard reaction. These findings may possibly be related to control of the advanced stage of the Maillard reaction.抄録全体を表示PDF形式でダウンロード (2232K) -

ジャーナル フリーRecently, it has been necessary to decide the most suitable package for new cosmetic products so that consumers can use them satisfactorily. We divided property of liquid cosmetics into two groups, Newtonian fluid and non-Newtonian fluid. We analyzed the fluidity of Newtonian fluid cosmetics by means of computer simulation and that of non-Newtonian fluid cosmetics by means of structural viscosity measurement. The computer simulation program of Newtonian fluidity was developed by using Bernoulli's equation. Non-Newtonian structural viscosity was measured by cone-and-plate viscometer. By these two methods, it become possible to develop the most suitable package for various types of liquid cosmetics.抄録全体を表示PDF形式でダウンロード (532K) -

ジャーナル フリーHair-dyeing with organic substances derived from plants and metals were studied.
Using white sheep hair, the factors of dyeing-time, temperature, content, pH-were tested. The degree of dyeing was measured by C. I. E L a b method with color difference meter. The metals, Fe2+, Co2+, Ag+ and substance with ortho-polyphenol or flavonoid structure dyed into the hair well. Previously used compounds like pyrogallol, gallic acid, gallotannin, and hematein gave bluish black and they did not look natural. However, it was found that catechol, rutin, extract of bing loung nut and persimon fruit, colored brownish black, close to the color of human hair. It was suggested that Ag dye rendered the hair deep brown and it was fast.抄録全体を表示PDF形式でダウンロード (801K)
