Description
Rosin, also known as colophony, is a brittle yellow or brown resin that remains after the distillation of turpentine from pine trees. It is an exudate gum with a slight odour of turpentine and is characterized by its use as a flux in soldering, as well as in the production of various products such as paints, varnishes, and surface coatings.
Uses
Used in Adhesive Industry:
Rosin is used as a tackifier for glue, providing additional adhesion and improving the bonding properties of the adhesive.
Used in Cosmetics Industry:
Rosin is used in cosmetics such as mascara, rouge, and eye shadow, serving as a binding agent and providing texture and stability to the products.
Used in Pharmaceutical Industry:
Rosin is used as a glazing agent in medicines and chewing gum, improving their texture and appearance.
Used in Printing Industry:
Rosin is used in the production of varnishes and surface coatings for printing inks, enhancing their durability and quality.
Used in Paper Industry:
Rosin is used as a sizing compound in paper production, improving the paper's strength and resistance to water.
Used in Soldering Industry:
Rosin is used as a flux in soldering, promoting the flow of solder and preventing oxidation during the process.
Used in Woodworking Industry:
Rosin is used as a component in pine-oil cleansers, helping to clean and maintain woodworking tools.
Used in Musical Instruments:
Rosin is used to provide grip to violin bows, enhancing the musician's ability to play the instrument smoothly.
Used in Athletic Equipment:
Rosin is used as an athletic grip aid, improving the grip and performance of athletes in various sports.
Used in Dental Industry:
Rosin is used as a component in dental impression materials and periodontal packings, aiding in the creation of accurate dental impressions and treatments.
Used in Optical Component Manufacturing:
A mixture of pitch and rosin is used to create a surface against which glass is polished when making optical components such as lenses, ensuring a high-quality finish.
Production Methods
Rosin,?also called colophony or Greek pitch (Latin: pix graeca), is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components.
Composition
Rosin is a complex mixture that mostly contains resin acids and a little amount of neutral fraction. Rosin mostly contains abietic ?type (abietic, levopimaric, pallustric, neoabietic, dehydroabietic and ?tetra abietic acids) and pimaric type (pimaric and isopimaric acids), besides neutral components.
Health effects
The fumes released during soldering have been cited as a causative agent of occupational asthma. The symptoms also include desquamation of bronchial epithelium.
Check Digit Verification of cas no
The CAS Registry Mumber 8050-09-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,5 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 8050-09:
(6*8)+(5*0)+(4*5)+(3*0)+(2*0)+(1*9)=77
77 % 10 = 7
So 8050-09-7 is a valid CAS Registry Number.
