Lipsticks are cosmetics which do not contain water and are usually preserved with parabens. When submitted to the Challenge Test, theses products did not reach the CTFA criteria, which means that microbiological contamination could occur before the end of its shelf life. The aim of this study was to evaluate the contamination level of 130 lipsticks after its use. Microorganisms were isolated from 14,6 % of the samples. However, only in two samples (1,5%) the contamination level exceeded the 100 CFU/g level, which means that, although the preservative system was not efficient to eliminate bacteria, the lack of free water was enough to prevent the microbial development. Total bacteria and fungi were determined by conventional methodology, according to CTFA Microbiological Guidelines. The microbes were then isolated and characterized as normal skin flora microorganisms. This suggest that products were contaminated by the constant application of lipsticks by consumers. This could lead to cross contamination when the same product is shared by several people. Extra care should be taken into account when this type of products are available to be tested by several consumers in demonstration displays.

The purposes of this study were to identify point makeup purchasing and using behavior according to the personal color awareness. Most women considered their favorite color first when purchasing lipsticks and skin color when purchasing cheek powder or foundation. They considered makeup concept first when applying lipsticks, eye shadows, and cheek powder but skin color applying foundations and manicures. Factors of personal color awareness were preferences & utilization awareness, other's advice, and direct awareness, and were segmented into PC intermediate group, high PC group, and PC retard group. PC intermediate group were in the late 20's and the early 30's, average incomes with high education, and patronized discount stores for point makeups, used fashion color as a criterion when selecting lipsticks, foundations, and manicures, apparel color when applying eye shadows, skin color when applying cheek creams, and preferred imported lipsticks and manicures. High PC group were among unmarried women in the early 20's, university students, high income households with medium level of pocket money, spent more for point makeup, and patronized department stores and internet shopping mall, used skin color or fashion color as criteria when selecting point makeup, referenced makeup concept when applying point makeup, preferred imported point makeup. PC retard group were among married women in the late 30's with low education and low income, spent less for point makeup and pocket money, and selected domestic point makeup, used their favorite color as a criterion when selecting point makeups and apparel color when applying lipsticks and cheek creams.

립스틱의 경우 광택과 광택 지속성은 일반적으로 관찰자의 주관적인 판단에 의해서 측정되곤 하였다. Glossmeter는 네일 에나멜과 같은 메이크업 화장품의 광택을 측정하는데 적용되었다. 그러나 립스틱의 경우에는 항상 일정하게 샘플링하기가 어려워 적용하는데 문제점이 있었다. 또한 광택 지속성은 측정할 수가 없었다. 본 연구에서는 기존의 주관적인 감각테스트에 크게 의존하던 립스틱의 광택 및 광택 지속성의 측정방법을 최적화하여 설정하였다. 도포물질, 크기, 도포회수 등의 변수들을 변화시켜 광택 측정법을 표준화하였다. 그리고 온도와 진동회수를 조절하여 광택 지속성을 측정할 수 있는 최적의 측정방법을 도입하였다. 이러한 방법을 적용하여 측정한 광택값은 주관적인 감각 테스트의 결과와 유사한 값을 나타내었다. 이 방법은 통계적 도구인 6시그마에 의해 재현성과 반복성이 유효하다는 것을 증명하였다.

Methylisothiazolinone (MIT) and chloromethylisothiazolinone (CMIT) cause allergic contact dermatitis and are banned cosmetics ingredients, except in rinse-off products. However, their presence has been detected in cosmetics. We report a UPLC-tandem MS/MS screening method for their simultaneous determination in cosmetics. To facilitate extraction from various matrices, pretreatment methods were developed for each sample type. The method was optimized through a series of assessments, including specificity, LOD, LOQ, linearity, recovery, stability, precision, and accuracy. The LODs and LOQs for MIT ranged from 0.054 and 0.163 ㎍ mL^-1 whereas those for CMIT ranged from 0.040 and 0.119 ㎍ mL^-1. The linear correlation coefficients (r²) were higher than 0.999. Relative standard deviations (RSDs) for both intra- and inter-day measurements ranged from 0.3 ~ 13.6 %. Recoveries at three different concentrations were within 87.9 ~ 118.9 %. The RSD for stability measurements of spiked samples was within 7 %. These results confirm the suitability of the developed method for the simultaneous quantitation of MIT and CMIT in cosmetics. Samples of 320 color cosmetics, including eyeshadows, solid lipsticks, liquid lipsticks, and nail polishes were analyzed using the developed method, and two of them were found to contain both MIT and CMIT and one of them was found to contain only MIT. This data and the method will aid the regulation of ingredients used in cosmetics.

A novel branched wax has been developed for the control of the hardness of oil-wax gels. Using this wax, glossier application and smoother texture but tough lipstick can be obtained. Oil-wax gels are oily solids composed of liquid and crystalline solid oils (waxes). They are widely used in various cosmetic products, especially lipsticks. The control of gel hardness is one of the most important techniques in improvement of the lipstick quality. Addition of small amounts of commercial branched paraffin wax (e.g. microcrystalline wax, b-PW) to n-paraffin wax (n-PW) has been commonly used to increase gel hardness. However, gel hardness is very sensitive to the quantity of b-PW and the gel obtained is not always hard enough for practical use. In this study we examined the relationship between the gel hardness and the properties of the wax crystal in the gel. We have found that, when b-PW is added to n-PW, the wax crystal size becomes smaller (hardening the gels) and its crystallinity is decreased (softening the gels) simultaneously. Considering this result, we have developed a novel branched wax, Bis(polyethylenyl)- tetramethyldisiloxane (named ESE). ESE molecules are composed of a central tetramethyldisiloxane unit (branch unit) with polyethylene units at both ends. The central unit may suppress crystal growth while the ends are expected to prevent a decrease in wax crystallinity during crystallization. When ESE is added to n-PW, the wax crystal obtained becomes smaller without decreasing in crystallinity; consequently, the gel hardness is dramatically increased. By using ESE, the total amount of wax in a lipstick can be decreased by 30％ without spoiling the stick toughness, thereby achieving glossy application and smooth texture.

Moisturizing the skin is one of the most important functions of skincare cosmetics, because water plays a significant role in keeping the skin healthy. There are various humectants including polyol (glycerin and 1,3-butylene glycol), water-soluble polymers, and botanical extracts. It is well known that the increased amount of polyol in lotion for obtaining high moisturizing effect gives a sticky feeling to the skin. Therefore, a few humectants that can give high moisturizing effect without a sticky feeling for lotion formula is available. On the other hand, oil-based lipstick is well known to have a difficulty to contain a large amount of hydrophilic humectants, because the humectants is unable to be mixed well into oil-based lipsticks and give the lips a peculiar taste. There are newly developed humectants, polyoxyethylene/polyoxypropylene dimethyl ether (EPDME) that can solve these problems describable above. EPDME is a random copolymer of ethylene oxide and propylene oxide. EPDME gives a low sticky feeling with a high moisturizing effect when it is used in lotion. As a remarkable character, EPDME can show not only a preventing effect on rough and dry skin, but also a improving effect upon the use for 1-4 weeks. EPDME can show a synergistic effect with glycerin on preventing to rough and dry skin. Since EPDME can be dissolved in oil-based formulation and used as an ingredient of lipsticks, EPDME can give a moisturizing effect that allows lip to be healthy condition. EPDME can also give no peculiar taste even upon the use of a large amount. EPDME is a useful cosmetic ingredient that can show a good skin care effect in both water-based formula and oil-based formula. EPDME of which polarity can be controllable is expected to be used for various cosmetic applications in near future.

In the Edo period speaking of hair culture, common women wore decorative pigtail ribbons on the right, and twisted from side to side their tressed hair in such a manner as ungeunmeori and traemeori. Instead of gachae, common women used gogae made of their own hair, ungeunmeori on forehead, or jjokjinmeori at the back of head. During the Edo period, people women naturally exposed their necklines as a way of exposing their faces in the aesthetically ceremonial act of wearing make-up. As for lipsticks, they rouged extracts from red petals of safflowers mainly on their lips, and sometimes on their cheeks by blending this with white powder. Samurai families disliked women who wore thick lip makeup. In the latter period, women painted their necklines or foreheads black, applied a small amount of rouge on their cheeks thinly or thickly, and colored a reddish color into their fingernails by using petals and leaves of balsam flowers. Despite the chronological and spatial proximity of the King Jeongjo period and the Edo period, it was found that there were no similarities between two countries' cosmetic cultures. Moreover, it was discovered that current TV dramas were being produced, even not based on historical evidence in the Jeongjo period.

This research has the purpose to examine the images sought for, makeup Consciousness, and behavioral aspects during makeup by the college girls in their 20s in the region of Daeieon and Chungnam that have strong interest in appearance and start color makeup in full scale, who form the main consumer layers in cosmetics market, and to analyze their preference on colors and feelings by the kinds of cosmetics, and their cosmetics purchase behavior. A questionnaire survey on the college girls in Daejeon and Chungnam region has shown the following results. The biggest reason college girls do the makeup was for a refined and pure image as well as protection of skin and covering defects. Their greatest concern was skin protection, and as for color selection, harmonizations of skin color and hair color were the largest consideration. In addition, the type of makeup they do most was foundation makeup, while pink was the most frequent lipstick color, and lip glow was mostly normal colors. However, they mostly answered that they do not use eye shadow, eye runner, and foundation. It was shown that their cosmetics purchase p]aces were specialized discount stores for about 47% nearly half of them, and they consider colors the most for lipsticks and eye shadows, and affinity to skin for foundations and basic cosmetics.
