BASIC CHEMICAL

Basic chemical dyes are a class of synthetic dyes characterized by their ability to form positive ions (cations) in solution. They are typically water-soluble and have strong color intensity. Basic dyes are mainly used for dyeing textiles, such as acrylic fibers, and sometimes leather, paper, and hair. They work by binding to negatively charged sites on fibers, providing vibrant and bright hues. These dyes are often applied in an acidic medium to enhance color fixation. However, they are not as durable as some other types of dyes and may be less resistant to washing and light exposure.

01. SODIUM HYDRO SULPHATE

Sodium hydrosulfate (NaHSO4), also known as sodium bisulfate, is a strong acidic salt formed by the reaction of sulfuric acid with sodium carbonate. It is commonly used as a cleaning agent, pH adjuster, and in various industrial processes such as textile and metal cleaning, and water treatment.

02. SODIUM SULPHATE

Sodium sulfate (Na2SO4) is a white, crystalline inorganic salt commonly used in detergents, glass manufacturing, and in the chemical industry. It is also utilized in paper, textiles, and water treatment processes. Sodium sulfate occurs naturally as the mineral thenardite and can be produced synthetically through chemical reactions.

03. SODIUM CARBONATE

Sodium carbonate (Na₂CO₃) is a white, water-soluble, crystalline compound commonly known as soda ash or washing soda. It is a strong alkaline substance used in glass manufacturing, water softening, detergents, and pH regulation. Naturally occurring in mineral deposits, it is also synthetically produced via the Solvay process.

04. COPPER SULPHATE

Copper sulfate (CuSO₄) is a blue, crystalline compound widely used in agriculture, industry, and chemistry. It serves as a fungicide, herbicide, and algaecide, as well as in electroplating and dyeing processes. Copper sulfate occurs as pentahydrate (CuSO₄·5H₂O) and is soluble in water, forming a characteristic blue solution.

05. HEC

HEC typically stands for Hydroxyethyl Cellulose, a water-soluble, non-ionic polymer derived from cellulose. It is widely used as a thickener, binder, film former, and stabilizer in industries like cosmetics, pharmaceuticals, paints, and food. HEC is valued for its ability to provide viscosity, enhance texture, and improve product performance in aqueous solutions.

05. HPMC

HPMC stands for Hydroxypropyl Methylcellulose, a non-ionic, water-soluble polymer derived from cellulose. It is widely used in pharmaceuticals, food, cosmetics, and construction industries. In pharmaceuticals, it acts as a binder, coating agent, and controlled-release matrix. In construction, it’s used in cement and plaster to improve workability, water retention, and adhesion.
