Application

Sarasil-JS (Conc) is stable to high alkaline pH and at elevated temperature. Depending upon the requirement 0.1-0.3 g/l of Sarasil-JS (Conc) can be used.

Note :

1. Sarasil-JS (Conc) is also suitable to be used as such for the end users. For immediate consumption by the end user, 1:1 to 1:10 dilutions can be made by using only soft water by stirring. Please note that it is to be used immediately (less than 10 min)

2. Sarasil-JS (Conc) is not advisable to use in high temperature/high pressure machines and hence cannot be used for polyester dyeing.

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.

Note :
  • 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.

Precautions

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.

Shelf Life: 9 months from the date of manufacturing, if stored under controlled conditions.
