dilution support for reliable operation and superior stability. Compatible with high-shear emulsifying equipment to form stable transparent micro-emulsions or macro-emulsions; designed to produce high-stability block silicone emulsions while addressing traditional issues such as oil floating and poor dispersibility.

Eco-friendly & Compliant

SVHC & Banned Chemicals Free | OEKO-TEX® 100 & ZDHC Compliant. Supporting high-end export growth.

Cotton Softening & Smoothing Silicone oil Instruction

72108 is a high-concentration, semi-self-emulsifying block copolymer raw oil, which cannot be directly applied to fibers or fabrics. Therefore, it should be emulsified before textile processing. It can be easily emulsified using conventional equipment and standard processes.

1) Emulsification Formula (Recommended)

2) Emulsification Process

Stir 72108 and the emulsifier until uniform before use:

1. Add 72108 and emulsifier into a mixer and stir thoroughly for 10 minutes until completely homogeneous;
2. Slowly add the acetic acid + water 1 mixture and continue stirring for 10 minutes until uniform;
3. Add approximately 1/5 of Water 2, stir for 5 minutes;
4. Add another 1/5 of Water 2, stir for 5 minutes;
5. Add the remaining Water 2, stir for 5 minutes;
6. Allow to stand for defoaming, filter and discharge;
7. Check the pH of the prepared solution (pH = 4.0–6.0). A clear micro-emulsion should be obtained.

3) Softening Application Process

Padding method (recommended)

• Dosagem:

  • Light-weight fabrics: 20–40 g/L
  • Heavy-weight fabrics: 40–60 g/L

• Working bath pH: 6.0–7.0 (optimal range)
• Setting conditions:

  • One dip–one nip (pickup 70–90%)
  • 160–170°C for 60–90 seconds

Exhaust (immersion) method

• Dosagem: 1.0–3.0% (o.w.f.)
• Liquor ratio: 1:20
• Processo:

  • 40–50°C for 10–20 min,
  • Hydro-extraction,
  • Drying at 100–120°C.
