Amphoteric
Original price was: $9,500.00.$9,400.00Current price is: $9,400.00.
Amphoteric refers to a substance or compound that has the ability to react as both an acid and a base. In other words, it can either accept a proton (H+) to act as a base or donate a proton to act as an acid, depending on the conditions of the reaction. The term “amphoteric” is often used in the context of chemistry to describe species that exhibit this dual nature of reactivity.
Description
Amphoteric Uses
Cleaning and detergents:
Amphoteric surfactants, such as cocoamidopropyl betaine, are widely used in cleaning products and detergents. These compounds exhibit excellent foaming, cleaning, and wetting properties and are effective in both acidic and alkaline environments.
Personal care products:
Amphoteric compounds are utilized in various personal care products like shampoos, conditioners, body washes, and facial cleansers. They contribute to the mildness of the formulations and help in maintaining the pH balance of the products.
Water treatment:
Amphoteric chemicals are employed in water treatment processes, particularly for controlling pH levels. They can act as both acid and base, allowing them to neutralize the water and maintain its desired pH range.
Pharmaceutical industry:
Amphoteric compounds find applications in the pharmaceutical sector. For example, certain drugs that exhibit both acidic and basic properties may require amphoteric substances as excipients to stabilize their formulations or enhance solubility.
Corrosion inhibitors:
Amphoteric corrosion inhibitors are used to protect metals from corrosion in various industrial applications. These compounds form a protective layer on the metal surface, preventing the corrosive attack by acids or bases.
Emulsion stabilization:
Amphoteric molecules are often utilized as emulsifiers to stabilize oil-in-water or water-in-oil emulsions. They help to prevent phase separation and maintain the stability of the emulsion over time.
Electroplating:
In electroplating processes, amphoteric substances can assist in the deposition of metals onto the desired surfaces. They can act as a source of protons (acidic) or hydroxide ions (basic), which are essential for the electrochemical reactions involved.

Adipic Acid
Adipic acid, chemically known as hexanedioic acid (C₆H₁₀O₄), is a key industrial organic compound recognized for its role in polymer production. Primarily, it serves as a crucial precursor in the manufacture of nylon 6,6, where it reacts with hexamethylenediamine to form this durable synthetic polymer, widely used in textiles, automotive components, and industrial plastics. Beyond nylon, adipic acid is integral to producing polyurethane foams, found in mattresses, insulation, and car seats, due to its ability to enhance material flexibility and strength. It also finds applications as a food additive (E355), where it acts as an acidity regulator in gelatin desserts, beverages, and baked goods. Additionally, adipic acid derivatives are used in plasticizers for PVC products, synthetic lubricants, adhesives, and even cosmetics. While traditionally derived from petroleum-based processes, growing interest in sustainable alternatives has spurred research into bio-based production methods using renewable resources. Overall, adipic acid’s versatility makes it indispensable across multiple industries, from manufacturing to food technology
Ascorbic acid
Ascorbic acid, also known as vitamin C, is a water-soluble vitamin that plays an important role in various physiological processes in the human body. It is an essential nutrient that cannot be produced by the body and must be obtained through dietary sources or supplements. Ascorbic acid acts as a powerful antioxidant, protecting cells and tissues from oxidative damage caused by free radicals. It also plays a critical role in the production of collagen, which is important for the health of skin, bones, and other connective tissues. Additionally, ascorbic acid is involved in the synthesis of neurotransmitters and the metabolism of proteins and fats. Deficiency in ascorbic acid can lead to a range of health problems, including scurvy, a condition characterized by fatigue, weakness, and bleeding gums.
