The interaction between clotrimazole and the pristine components, namely cyclodextrin and halloysite, was thoroughly investigated by several techniques such as DSC, TGA, UV-vis spectroscopy and some adsorption studies were, also, carried out. The release of the antifungine molecule was finally investigated in a medium that imitates the physiological conditions. Halloysite nanotubes (HNTs) are natural occurring mineral clay nanotubes that have excellent application potential in different fields.

The metal is used widely in construction materials (e.g., for buildings and infrastructure), vehicles, aircrafts, electronics and packaging materials (NRCan, 2018). Aluminum compounds are also used by the pharmaceutical industry in personal care products, in food packaging and as a food additive. In addition, aluminum is used widely in treatment plants for drinking water, wastewater and industrial water. In drinking water treatment, aluminum salts are applied to remove turbidity, organic material and microorganisms. Statistics Canada (2013) reports that aluminum-based coagulants are used in the treatment process for 69.2% of surface waters and 6.7% of groundwater/GUDI (groundwater under the direct influence of surface water).

With this substance, safety is a major concern, as it emits strong fumes that can I am particularly interested in starting with easy to source options such as Sulfuric Acid (“battery acid” at approx 1. There are a lot of products from chemical companies in the market and several types depend on the applications such as hydrochloric acid, sulfuric acid, organic acids, and so on. In another alternative, the compositions of the present invention are formulated in compressed forms, such as suspension tablets and effervescent tablets, such that upon reaction with water or other diluents, the aqueous form of the composition is produced for oral administration. These forms are particularly useful for medicating.

Brand names include Alu-Cap, Aludrox, Gaviscon, and Pepsamar. Chronic, excessive use of aluminum hydroxide may deplete the body of phosphate, causing metabolic bone disease (e.g., osteoporosis, osteomalacia) and risking spontaneous fractures, especially in the malnourished. Aluminum hydroxide may alter the absorption of certain drugs [including some used to treat cardiac disease or high blood pressure] so they should not be taken simultaneously. Aluminum Hydroxide [Al(OH)3] – Compared to magnesium hydroxide, aluminum hydroxide is a weak, slow-acting antacid, and its acid-neutralizing effect varies among commercial products. It appears that the evidence of improved absorption of mineral acid chelates occurs when the mineral compounds are taken with foods containing absorption inhibitors such as phytates and oxalates.

For medical treatment such formulations allow for sustained long-lasting drug delivery directly on the hair surface, also enhanced in the cuticle openings. For coloring, this process allows avoiding a direct hair contact with dye encased inside the clay nanotubes and provides a possibility to load water insoluble dyes from an organic solvent, store the formulation for a long time in dried form, and then apply to hair as an aqueous nanotube suspension. The described technique works with human and other mammal hairs and halloysite nanoclay coating is resilient against multiple shampoo washing. The most promising, halloysite tubule clay, is a biocompatible natural material which may be loaded with basic red, blue, and yellow dyes for optimized hair color, and also with drugs (e.g., antilice care-permethrin) to enhance the treatment efficiency with sustained release. This functionalized nanotube coating may have applications in human medical and beauty formulations, as well as veterinary applications.

In cases where aluminum removal is required and coagulation is not feasible, the responsible drinking water authority in the affected jurisdiction should be contacted to discuss possible options. At high concentrations (5-6 mg/L) aluminum may cause an unpleasant taste, and at very high concentrations (100-500 mg/L) the water may feel “sticky” (Hrudey and Hrudey, 2014). High concentrations have occurred as a result of accidents at full-scale water treatment plants using aluminum-based coagulants. This highlights the need for standard operating procedures, alarms and interlocks, and contingency plans when dealing with water treatment chemicals. The neurotoxicity of aluminum is well documented in human studies; however, many of these studies have been cases of medical treatment for specific disease conditions (e.g., patients with impaired kidney function).

  • For aluminum hydroxide to be beneficial in preventing phosphate absorption, it must be administered with meals or snacks.
  • A great meaning in treatment of gastritis and ulcer disease of stomach and duodenum is taken by gastric protectors – drugs that increase protection function of sputum and stableness of mucous layer (carbenoxolone, misoprostole).
  • Sulphuric acid widens the potential of HNTs in the field of catalysis while weak acids such as acetic and acrylic acids give a controlled and homogeneous lumen increase with the corresponding increase in the loading capacity.
  • This typically involves minimizing the aluminum concentration entering the distribution system and implementing best practices to maintain stable chemical and biological water quality conditions throughout the system, as well as to minimize physical and hydraulic disturbances.

The proposed operational guidance (OG) of 0.05 mg/L is recommended to be applied to locational running annual averages of monthly values for filtered water in treatment plants using aluminum-based coagulants and to all distribution systems based on a locational running annual average of quarterly values. This OG may be difficult to achieve in small plants that have elevated levels of naturally-occurring aluminum in the source water and/or in small plants where an aluminum-based coagulant is used and coagulation pH is not strictly controlled.

Increased concentrations in treated water tended to occur when raw water aluminum concentrations were low (see Table 5). The concentration increases clearly highlight the impacts of improper coagulation on aluminum residuals and the potential for treated water concentrations to exceed the proposed MAC, although the use of other water treatment chemicals may have contributed to the increase (see Section

In vitro release studies in simulated gastric fluid indicate that these new hybrid floating carriers are suitable for gastro retentive controlled release applications. Halloysite nanotubes (HNTs) have attracted a technologic and scientific attention as reinforcements of epoxy‐based nanocomposites. However, their reported interaction with epoxy matrices is varied and the controlled dispersion of HNTs is still a challenge. In this work, we study the effect of chemical reactions taking place in the dispersion process of halloysite and their possible influence in the composite’s properties. HNTs’ surface was modified through an alkaline treatment and by grafting two aminosilanes with different chain lengths and functionality numbers.
