Abstract:

In order to better characterize metal soaps found in paint films or on metal surfaces, several metal soaps were synthesized and their X-ray powder diffraction patterns measured. Metal soaps were obtained from four different fatty acids found in drying oils, two saturated (palmitic and stearic acids) and two unsaturated (oleic and linoleic acids), and from copper, zinc, and lead, three metals that are typically found in metal alloys and paint systems. X-ray powder diffraction data are reported for the following compounds: palmitic acid, stearic acid, zinc palmitate, zinc stearate, zinc oleate,

In contrast to modern lead white, traditional stack process lead white is characterized by a wide particle size distribution. Changes in particle morphology and distrib

Abstract:

ABSTRACTSoap formation in traditional oil paintings occurs when heavy-metal-containing pigments, such as lead white, 2Pb(CO3)2·Pb(OH)2, and lead-tin yellow type I, Pb2SnO4, react with fatty acids in the binding medium. These soaps may form aggregates that can be 100-200 μm in diameter, which swell and protrude through the paint surface, resulting in the degradation of the paint film and damage to the integrity of the artwork. In addition, soap formation has been reported to play a role in the increased transparency of paint films that allows the painting support, the preparatory drawing, and t

Soap is a daily-use product for both laundry and bathing. It is obtained by the saponification reaction of an oil with a strong base (KOH, NaOH...). In the Democratic Republic of the Congo, quality control of solid soaps is often limited to determining moisture content and total free alkali. However, the effectiveness and cleaning properties of a soap depend on several other physicochemical parameters in addition to these two. Nine laundry soaps and one toilet soap sold on the KIKWIT market were analyzed to determine not only water content and total free alkali, but also pH, alcohol- and water

Abstract:

Products designed to cleanse the skin commonly do so through surfactant action, which leads to the lowering of the surface tension of the skin to facilitate the removal of dirt from its surface. Skin cleansers generally come in one of two types: soap-based and synthetic detergents, or syndets. While the latter can effectively maintain the native skin structure, function and integrity, the former tends to negatively affect the skin by causing barrier disruption, lipid dissolution and pH alteration. Despite this, soap is still often preferred, possibly due to the negative connotations around any

Abstract:

Metal soaps formation is a well-known issue in oil paintings. Along the lifetime of the painting, carboxylic acids coming from drying oil (free fatty acids, acids from hydrolysis of triglycerides and from oxidation processes) can react with cations of some pigments (in particular, smalt, lead white and zinc white) forming the related carboxylic salts. As observed by many authors, the formation of these carboxylates, with the tendency to migrate and to aggregate, not only modifies the behavior and the aspect of the paint film but also complicates the cleaning approach.

Abstract:

The expected cutaneous adverse effects (CAE) of oncology therapies can be disabling and even force the patient to discontinue treatment. The incorporation of cosmetics into skin care regimens (SCRs) as true therapeutic adjuvants can prevent, control, and avoid sequelae. However, cosmetics may also lead to adverse reactions in patients. The aim of our study was to assess the impact of the tolerability of cosmetics used in routine skin care on quality of life in this vulnerable population group through a survey. In addition, information was collected to improve the knowledge of the beneficial ef

Abstract:

All shampoos contain various harmful components that accumulate in the body, which can harm human health in general. They can cause allergies, provoke aging, lead to nervous disorders and cardiovascular disease. But, despite this, these substances can not be excluded from the composition of modern shampoos, as without this cosmetics will lose their properties. Choosing the right shampoo will help reduce the risk of harmful effects, but you need to know how it can adversely affect the health of an ingredient. The result is the recommended lists of specific shampoos that take into account all th

"Popped" volcanic ash is one of the latest developments in product research by the State Geological Survey of Kansas. In the laboratories of the Survey, Kansas ash bas been bloated, or "popped"-and in this form has new industrial applications. Crushed, cracked, screened, and bonded, the "popped" ash has been tested for its suitability in various products. Bloated ash from Kansas has some interesting characteristics and, we think, potential for development. Results achieved thus far are analyzed in this report. Experiments are continuing, and not all Kansas ash has yet been tested for its bloat

The synthesis of BaPbO3 from a wide range of mixtures containing metalorganic precursors, nitrate precursors, lead oxides, barium oxide and peroxide was investigated, and the kinetics was analyzed using the Johnson–Mehl–Avrami (JMA) equation. It was found that Ba and Pb stearate soaps and Pb oxalate that were used as metalorganic precursors formed BaCO3 and PbO or Pb3O4 after firing at 440 °C. The formation rate of BaPbO3 from a metalorganic precursor system is not higher than that from the conventional BaCO3–PbO system and does not depend on mixing methods or the kinds of metalorganic precurs

Abstract:

Kenya is one of the leading exporters of snap beans (Phaseolus vulgaris) to Europe, but the export volume has remained below potential mainly due to failure to meet the market quality standards. The quality concerns include the presence of regulated and quarantine pests, pesticide residues, harmful organisms, and noncompliance with the technical standards. These challenges call for the development of alternative approaches in overcoming the phytosanitary and quality challenges in the export of snap beans and other fresh vegetables. These may include integrated pest management (IPM) approaches
