Rosin is a sticky substance that comes from trees like pine and some other plants. It is semi transparent and varies in color from yellow to black. It is made of marijuana flower, hash, or kief and transformed into full melt hash oil. It is made by exposing cannabis to heat and pressure in order to force out the terpense and cannabinoids found in plants trichome glands. wood rosin obtained by solvent extraction of the stumps , is usually of the darker color. Gum rosin is obtained upon distillation of the oleoresin from pine trees. rosin and its chemical derivates used form soap, varnishes, sealing wax, printing inks, driers, size for paper, adhesives, binders, soldering fluxes, gloss oil for paints, pitch for casks,

BRIEF DESCRIPTION AND NATURAL SOURCE
Rosin or colophony is a natural abundant, cheap and non toxic, raw material which can be easily modified to obtain numerous useful products, it is basically obtained or constituted by different species of pine, as crude turpentine. Distillation in large copper stills is carried out in order to separate the rosin. Rosin is a fragile and brittle, with piny odor. The shape and physical appearance of rosin vary, some rosins form crystals and some are solid glassy. The term rosin originated as a method of making a product used to create friction violin bows. Rosin can rival the flavor, potency and yield of other solvent based extraction products. Rosin certain extraction process may result in loss of some terpenes. Rosin simply use heat and pressure and does not require any additional cleaning, so your final product is clean and ready in just a minutes.
USES IN PHARMACOLOGICAL APPLICATIONS
Rosin is being widely used in pharmacological applications. The derivatives obtained from rosin have excellent coating and film foaming properties. The most significant advantage of common polymers is that they are proficient for concoction alterations. One such biopolymer, rosin, and its subordinates have been chemically assessed as microencapsulating materials, film framing operator and as restricting specialist in detailing of tablets. They are additionally utilized in definition of biting gum bases and beautifiers. Rosin is used in film forming, coating tablet, forming microcapsules and nanoparticles. Rosin has shown mediate anti bacterial action on gram positive bacterial species. Rosin can be used as a glazing agent in medicine and chewing gum. Rosin forms an ingredient in several plaster and ointments. Glycerol, sorbitol and minnitol ester of rosin are used in chewing gum bases for medicinal application.
Rosin is being extensively used in soap industries, manufacturing of varnishes, waxes and other adhesives. It is also used in for internal reinforcement of many thin skinned metal objects, where it is melted and poured into hollow thin skinned objects and it get harden easily. Rosin is a flux used in soldering. The lead-tin patch usually utilized in gadgets has 1 to 2% rosin by weight as a transition center, helping the liquid metal stream and improving an association by decreasing the stubborn strong oxide layer shaped at the surface back to metal. It is regularly observed as a consumed or clear buildup around new welding.
Artistic work utilizes rosin for gum based paint emulsions and as painting-medium segment for oil artworks. It is solvent in oil of turpentine and turpentine substitute, and should be warmed. In a printmaking procedure, aquatint rosin is utilized on the scratching plate so as to make surfaces in dim tones. Rosin could also be used as glue due to its elasticity. Rosin is some of the time utilized as a fixing in naming wax utilized in fly tying. Rosin is utilized hot to de-typify epoxy coordinated circuits.
SAFETY AND PRECAUTIONS
It is very flammable and produces smoky flame, special attention to be paid while melting it. Exposure to working on rosin for long time causes asthma due to its fumes. Prolonged use of rosin while handling rosin coated products such as laser printers or photo state machines, can lead to type of industrial contact dermatitis.
