* Acid number is determined at the end of production. Prolonged storage will result in an increase in

slight oxidation, which will result in an increase in acid number. The smaller particle size is more

susceptible to surface oxidation.

Plant dyes (526534) Plant dyes are extracted from raw materials such as flowers, shells, fruits, leaves and so on through multiple processes, powdering-extracting-ultrasonic processing-concentrating-air drying. Plant dyes can be used for cotton, linen, silk and wool dyeing. They have no side effects on our body. With natural color, well texture and pleasant fragrance, the dyed fabrics are the best choice for high grade garments. . Application Dosage: 0.5~5%(o.w.f), different usage according to color deep requirement
  1. Dyeing for cotton fabrics:
(1) Modification processing: natural modifier dosage is 1-2 times weights of cotton fabric, 95°C/30min ----washing----dyeing (2) Dyeing processing: 95°C/60min(pH 3-4) ----washing----soaping (soaping agent 5g/L, boiling 1-2min) ----washing----drying
  1. Dyeing for wool and silk fabrics:
Adopt acid- boiling dyeing for both wool and silk fabric. Adjust pH with glacial acetic acid. pH for dyeing wool fabric is 4. pH for silk fabric is 5.

Natamycin(95%) (523557)
  • Natamycin (pimaricin) is a polyene macrolide antibiotic produced by submerged aerobic fermentation of Streptomycesnatalensis and related species. Fermentation is conducted for several days, and the antibiotic is isolated either by broth extraction or by extraction of the mycelium. The activity of natamycin against yeasts and moulds, but not bacteria, makes it convenient for use in foods that undergo a ripening period after processing. Its low solubility in water and most organic solvents makes it suitable for the surface treatment of foods.
    ITEM DESCRIPTION
    Product Name 95% Natamycin
    Strain Streptomycesnatalensis
    Appearance White to creamy-white powder and odorless
    EU No. E235
    Molecular Formula C33H47NO13

  • Its medical use is now confined to topical treatment of corneal fungal infections and the prevention of such infections in users of contact lens. Natamycin is used topically in veterinary medicine to treat mycotic infections, such as ringworm in cattle and horses. Previously, it was used topically against fungal infections of the skin and mucous membranes in humans.
