Ammonium Chloride (NH4Cl),also called sal ammoniac, the salt of ammonia and hydrogen chloride. Its principal uses are as a nitrogen supply in fertilizers and as an electrolyte in dry cells, and it is also extensively employed as a constituent of galvanizing, tinning, and soldering fluxes to remove oxide coatings from metals and thereby improve the adhesion of the solders. It is a component of many proprietary cold medicines and cough remedies because of its efficacy as an expectorant, and in veterinary medicine, it is used to prevent urinary stones in goats, cattle, and sheep. Ammonium chloride is a colourless crystalline substance. It is highly soluble in water, readily forming a slightly acidic solution. It vaporizes without melting at 340 �°C (644 �°F) to form equal volumes of ammonia and hydrogen chloride. Ammonium chloride is yielded as a by-product in the ammonia-soda process for making sodium carbonate. It also is produced by reaction of ammonium sulfate and sodium chloride solutions. When mixed with slaked lime (calcium carbonate), ammonia gas is the result.

Boric acid, also called hydrogen borate, boracic acid, and orthoboric acid is a weak, monobasic Lewis acid of boron. However, some of its behaviour towards some chemical reactions suggest it to be tribasic acid in the Br nsted sense as well. Boric acid is often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other chemical compounds. It has the chemical formula H3BO3 (sometimes written B(OH)3), and exists in the form of colorless crystals or a white powder that dissolves in water. When occurring as a mineral, it is called sassolite.

Aluminium sulfate is a chemical compound with the formula Al2(SO4)3. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water[3][4] and waste water treatment plants, and also in paper manufacturing. Aluminium sulfate is used in water purification and as a mordant in dyeing and printing textiles. In water purification, it causes impurities to coagulate into larger particles and then settle to the bottom of the container (or be filtered out) more easily. This process is called coagulation or flocculation. Research suggests that in Australia, aluminium sulfate used this way in drinking water treatment is the primary source of hydrogen sulfide gas in sanitary sewer systems

Epiduo gel is a prescription medication used to treat acne vulgaris, a common skin condition characterized by the formation of pimples, blackheads, and whiteheads. It is a combination product that contains two active ingredients: adapalene and benzoyl peroxide. Adapalene is a retinoid that helps to regulate skin cell turnover, prevent the formation of new acne lesions, and reduce inflammation. Benzoyl peroxide is an antimicrobial agent that effectively kills the bacteria responsible for causing acne and helps to unclog pores by removing excess oil and dead skin cells. Epiduo gel is typically transparent and odorless, with a smooth texture that allows for easy application onto the affected areas of the skin. It is available in different strengths, depending on the severity of the acne and the individual's skin sensitivity. The gel is applied once daily in the evening, following a gentle cleansing of the skin. It is important to use Epiduo gel regularly and as directed by a healthcare professional to achieve the best results. Improvement in acne symptoms may be seen within a few weeks of starting treatment, but it may take up to 12 weeks to see the full benefits. While Epiduo gel is generally well-tolerated, some individuals may experience mild side effects such as dryness, redness, peeling, or stinging at the application site. These side effects usually subside with continued use or can be managed by adjusting the frequency of application or using moisturizers as recommended by a healthcare provider. Overall, Epiduo gel is an effective treatment option for acne when used as part of a comprehensive skincare routine under the guidance of a healthcare professional. It can help improve the appearance of acne-prone skin, reduce the frequency and severity of breakouts, and promote clearer, smoother skin over time.
