Glycolic Acid

Glycolic acid is the smallest α-hydroxy acid. It is used in various skin-care products. It is used to improve the skin's appearance and texture. It may reduce wrinkles, acne scarring, hyperpigmentation and improve many other skin conditions, including actinic keratosis, hyperkeratosis, and seborrheic keratosis. Glycolic acid is also a useful intermediate for organic synthesis, in a range of reactions including: oxidation-reduction, esterification and long chain polymerization. It is used as a monomer in the preparation of polyglycolic acid and other biocompatible copolymers. Among other uses this compound finds employment in the textile industry as a dyeing and tanning agent, in food processing as a flavoring agent and as a preservative. Glycolic acid is often included into emulsion polymers, solvents and additives for ink and paint in order to improve flow properties and impart gloss.

Properties Suppliers
Guaiacol

Guaiacol is a naturally occurring organic compound. Although it is biosynthesized by a variety of organisms, this colorless aromatic oil is usually derived from guaiacum or wood creosote. It is present in wood smoke, resulting from the pyrolysis of lignin. Guaiacol is a precursor to various flavorants such as eugenol and vanillin. Its derivatives are used medicinally as an expectorant, antiseptic, and local anesthetic. It also can be used as a dye in chemical reactions as oxygen will turn guaiacol from colorless to brown.

Gum Arabic

Gum arabic, also known as gum acacia, chaar gund, char goond or meska, is a natural gum made of hardened sap taken from two species of the acacia tree; Acacia senegal and Acacia seyal. Gum arabic is a key ingredient in traditional lithography and is used in printing, paint production, glue, cosmetics and various industrial applications, including viscosity control in inks and in textile industries.

Properties Suppliers
Gum Dammer

Gum Dammer (non-toluene) is modified from the pure natural gum dammer. Gum Dammer can be directly added in the production of ink, simplified productuin process, improve production efficiency. The quality is better than that of natural gum dammer. It is used in PP, PE plastic printing ink. It can improve the system’s properties. Such as adhesion, flowability, glossness. Especially in the untreated plastic film.

Properties Suppliers
HECELLOSE

HECELLOSE is a non-ionic water soluble cellulose ether used as a thickner and rheology modifier in water based paints such as Emulsion Paints, Distempers, Acrylic Putty, Primers, etc.

Properties Suppliers
Harshol CRL

Harshol CRL is a powerful retarding, migrating and levelling agent specially for cationic, reactive, direct, acid & metal complex dyes. It gives excellent fastness properties. Fabric dyed with Harshol CRL gives good exhaustion .it does not allow Cationic Dyes to migrate on polyester fabric.

Properties Suppliers
Harshol PD

Harshol PD is a high performance textile auxiliary having moderate foaming properties. This formulation has a multifunction application in dyeing as well as printing of synthetic and natural fabric, and various blends. It has excellent buffering properties during dyeing /printing in acidic medium and its buffering is stable up till moderate hard water giving good results and good exhaustion of the dye. It has the ability to give superior clarity, brightness and high dye value. It gives shades with consistency and reproducibility is maintained even in the case of sensitive dyes and their combinations .It has the tendency to give constant ph throughout the dyeing/printing process. It is completely safe for viscose blended synthetic fabric.

Properties Suppliers
Hematein

Hematein is an oxidized derivative of haematoxylin, used in staining. It exhibits indicator-like properties, being blue and less soluble in aqueous alkaline conditions, and red and more soluble in alcoholic acidic conditions. In acidic conditions, complexes of hematein with metals bind to arginine residues of nuclear histones. The color of the stained nuclei depends on the salt used.

Properties Suppliers
Hematoxylin

Haematoxylin is extracted from the heartwood of the logwood tree. When oxidized it forms haematein, a compound that forms strongly colored complexes with certain metal ions, notably Fe(III) and Al(III) salts. Metal-haematein complexes are used to stain cell nuclei prior to examination under a microscope. Haematoxylin and eosin stain is one of the most commonly used stains in histology.
