Instructions For Dilution

Procedure to prepare 15% Sarasil-JS (Conc)

  • Take 60.5 parts of DM water (40-50 deg.C)
  • To this, add 1 part of Saracrease (Conc) [viscosity modifier]. Stir at 3000 rpm for 20-25 min.
  • Add Xanthum gum. Stir at 3000 rpm for 10-15 min.
  • Cool to room temp. and then add 37.5 parts Sarasil-JS (Conc).
  • Stir at 100 rpm for 20-25 min to get homogenous product

Preservation: It is recommended to add 0.1% Bronopol (2-Bromo,2-nitropropane, 1,3-diol) or Methyl Paraben (methyl para hydroxy benzoate) as an antimicrobial agent to avoid fungal / microbial growth.

  • Diluted Sarasil-JS (Conc) may show non-uniform appearance as diluted product is not an emulsion but dispersion.
  • Dispersion of the product is stabilized by polysaccharide.

It is advisable to utilize the diluted product within 2 months. Stir well before use.


Storage : Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg C. Close lids firmly to avoid contact with air and moisture.
