从感官分析和消费者调研角度研究不同剂型防晒产品特征

分别从感官分析和消费者调研两个角度比较了防晒乳霜、防晒摇珠和防晒喷雾三种不同剂型防晒产品的特点。收集64款市售防晒产品的定量描述感官分析结果,将其按剂型分为三类,采用单因素方差分析剖析三种剂型防晒产品在感官属性上的差异。通过消费者调研收集了230份市场问卷了解消费者对三类防晒产品的认知。结果表明,肤感体验部分的感官分析结果和消费者调研得出的结论基本一致,具有一定的相关性,但感官分析和消费调研两者各有所长。两者的结果均显示出防晒摇珠肤感更轻盈,防晒乳霜的肤感居中,防晒喷雾的肤感最重。感官分析可以从统计学角度区分三者肤感的差异,消费者调研也从消费者的角度证实这些差异确实存在,因此感官分析的结果可用于描述消费者的肤感认知,具有一定的可替代性。通过比较三种剂型防晒产品的肤感差异可以有效地指导化妆品开发人员更好区分三者的优势和劣势,同时扬长补短,开发出肤感更加舒适的防晒产品。

促销质量亟待提升

随着市场竞争日趋激烈,每逢节假日,以打折、让利为主要内容的促销战便陆续展开。其实,这种引导消费者仅仅从价格层面去选购产品是较为原始、低端的促销方式,从长远看,既不理性,也不科学。为了培育更为健康的市场氛围,陶瓷企业和商家在进行促销时,首先产品要保质保量,推广方式精准有效,同时完善活动细节,并引导消费者从产品、设计、服务等多角度体验,从而提升促销档次,增强消费者的产品认同感。

Lipid/surfactant compounds as a new tool to optimize skin-care properties of personal-cleansing products

Surfactants are commonly used in personal-care products to increase cleansing performance and to create pleasing foam. However, surfactants can also damage the skin by removing skin lipids and causing corneocytes to swell, resulting in increased skin roughness and transepidermal water loss. Newly established methods help to quantify these effects in controlled consumer studies. In addition, in vitro experiments with skin cell cultures show the potential inflammatory action of surfactants, which in the in vivo situation may provoke skin irritation. These detrimental effects are even enhanced by frequent treatment with surfactant-based personal-care products. Together with the use of mild surfactant combinations, the addition of surfactant-compatible lipid compounds has proved a convenient way of not only counteracting the negative side effects of surfactants but also exerting positive skin effects. In a controlled consumer study, analysis of skin lipids after skin cleansing revealed the lipid-layer strengthening efficacy of lipid/surfactant mixtures that can be solubilized in the personal-care formulation or disperses as waxy particles. As a result, skin roughness after cleansing treatment, as measured by fast optical in vivo topometry of the skin, is improved, and consumers perceive that their skin is smooth and cared for.

A Review on the Potential Use of Chitosan-Based Delivery System in Mild Facial Cleansing Formulation

The facial cleansing products segment has grown over the years and most surfactant-based systems do not retain many of the active ingredients on the skin. Development of a positively charged vesicle as the delivery vehicle for personal cleansing products is based on the negatively charged nature of the skin surface. Chitosan has the potential to be used as a vesicle to encapsulate active ingredients and can be used in facial formulations that are based on amphoteric surfactant with or without the addition of nonionic surfactant. This review briefly summarizes the potential of chitosan nanoparticles as the delivery system in facial cleansing formulations.     

Helle Montanwachs-Derivate

Light Coloured Montana Wax Derivatives Light coloured or almost colourless montana wax derivatives are obtained by careful bleaching of raw montana wax with varying amounts of chromic acid according to a new process. In these products, the ratio of wax acid to wax ester differs from the well-known products obtained by oxidation. The characteristic physical and chemical data are compared, and their impact on practical properties, such as emulsion formation with water, formation of wax/solvent mixtures, and compatibility with other waxes, is shown. The light coloured products obtained by oxidation of raw montana wax can be used as raw materials for cleansing agents and cosmetics, and as auxiliaries for the processing of plastics.     

Kunststoffe in der Milchwirtschaft — eine kritische Studie,V. Mitteilung: Zur Reinigung und Desinfektion von Kunststoffoberflächen 2. Teil: Hygienische Beschaffenheit von Kunststoffoberflächen und ihre Folgen

Plastics in the Milk Industry — A Critical Study, V. Communication: Cleansing and Disinfection of Plastic Surfaces 2nd Part: Hygienic State of Plastic Surfaces and Their Consequences Plastic articles, meant for repeated use in direct contact with food-stuffs can permanently establish themselves, only if success is achieved in maintaining plastic appliances and parts clean and germ-free without much difficulty. Because in some respects the properties of the plastics deviate from those of hitherto employed materials of construction, the former set specific requirements on cleansing agents and cleansing processes. The cleansing solutions for the plastics must be physico-chemically more effective, in order to overcome the strong adhesion of fatty impurities. Since it is basically doubtful, whether polyolefines without adverse effects can at all be employed for repeated use in direct contact with fat-containing milk products, intensive trials should be made with plastics having lower affinity for fat.     

Fett und seine technische Anwendung

Fat and Its Technical Application Secondary products of fats can be classified into 3 groups according to their technical use. These products constitute surface-active substances, oily or waxy substances, and fatty nitrogen compounds. A few selected examples should show the versatile fields of application of such products. Surfactants are not only used in washing and cleansing agents but also for the production of modern materials of construction. New types of ester oils predominate in the field of technical lubrication for a wide range of temperature and mechanical stress. Fatty nitrogen compounds alter the texture of textiles, alternatively, they are used in flotation processes for regulating the wettability. The examples chosen show how the secondary products of fats have entered various branches of the industry and have either enabled to improve the technical processes or made these processes altogether feasible.

Keimgehalt von Körperpflegemitteln

Germ Content of Cosmetics Different charges of indigenous and foreign products consisting of 26 skin nourishing creams, 11 skin cleansing preparations, 5 skin tonics, 11 vanishing creams and 7 cold creams were investigated bacteriologically in order to find out as to how far these preparations are hygienically unobjectionable. The difficulties in testing due to the consistency and composition of the base as well as due to the addition of mostly bacteriostatic preservatives could be largely overcome. The result, according to which more than one fourth of the cosmetics tested were not hygiene-esthetically unobjectionable, clearly shows that from the prophylactical point much is still to be done in production and filling.     

Degradation of Recalcitrant Surfactants in Wastewater by Ozonation and Advanced Oxidation Processes: A Review

Surfactants are used in varieties of industrial cleansing processes as well as in consumer products. Spent surfactants normally enter domestic or industrial wastewater and are treated biologically. However, some of them are resistant to biodegradation and are released into the environment. Thus, the toxicity and environmental persistence of these surfactants are emerging concerns. Based on extensive review of the literature, ozonation and advanced oxidation using various combinations of ozone, hydrogen peroxide, ultraviolet light irradiation, and iron salts were found effective in degrading recalcitrant surfactants, including linear alkylbenzene sulfonates, alkylphenol ethoxylates, and quaternary ammonium surfactants. Biodegradability of these surfactants was improved after the treatment to some extent in the aqueous solution as well as in real wastewaters.
