Rosin Lumps or rock rosin also known as colophony is a solid form (amber-brown color) of resin obtained from pines. Used in printing inks, varnishes, adhesives/glues, soap, paper sizing, soda, soldering fluxes, and sealing wax.

Guar Gum is derived from the ground endosperm of Cyamopsis Tetragonolobus, a plant of the Leguminosae family. Guar Gum extracted from Guar beans.

PVOH1 (PVOH5042 or Elvanol® 50-42) is a high viscosity, partially (88%) hydrolised Polyvinyl Alcohol (PVOH) that can dissolve in cold water (Heating or warm water is suggested for complete dissolving). A solution of 10% up to 15% provides the maximum viscosity of 47 CPS. It offers high tensile strength and tear resistance. It is an excellent disperser stabilizer. Elvanol® 50-42 is suggested for evaluation in the stabilization of vinyl acetate, polystyrene and polyvinyl chloride emulsions. It has additional applications in remoisturizing adhesives, temporary binder for ceramics, water-soluble film; paper adhesives, coldwater soluble film, photosensitive coatings, binder for joint compounds and texture coatings and as a soil anti-redeposition agent.

This nonionic self-emulsifying wax is mild, provides excellent stability, and is very easy to use. It is ideal for lotions and creams. Emulsifying Wax NF can be used to make viscous (thick) or thin emulsions, depending upon the concentration at which it is used. Use this vegetable based emulsifier at about 5% to keep water and oil combined for lotions, creams, conditioners, etc. Melt wax with other fats and waxes.

Rosin powder. tasteless, odorless, 70 percent C.P. resins especially soluble in aromatic and chlorinated solvents.
Used as a grip-improving powderer. Apply to athletes’ hands or soles of basketball shoes for improved traction. Dust on handles of baseball and softball bats for improved grip.

Partially hydrogenated Chinese Rosin has a lighter color and is more stable.

Rosin Flakes (and clumps) also known as colophony, light yellow-amber color, is a solid form of resin obtained from pines. Used in printing inks, varnishes, adhesives/glues, soap, paper sizing, soda, soldering fluxes, and sealing wax.

Agar, Fine Ground U.S.P.,
Gelidium 700AM, gelling agaent for making agar plates. Does not contain nutrients.
Agar is a galactose polymer (or agarose) obtained from the cell walls of some species of red algae or seaweed (Sphaerococcus euchema) and species of Gelidium. It is also known as Kanten, Agar-Agar, or Agal-Agal (Ceylon Agar).

Added at a rate of 1% to 2% can convert any water based liquid to gel.

PVOH2 or PVOH7130 (Elvanol® 71-30) is a medium viscosity, fully hydrolized grade of polyvinyl alcohol. White, powder, soluble in hot water but insoluble in cold water and common organic solvents. For most applications, PVOH2 is prepared in water solutions. On evaporation of water, transparent films are formed which have high tensile strength and tear resistance. The binder characteristics of PVOH2 offer excellent adhesion to porous, hydrophilic surfaces.
