  Permenant Softners  
  These are Silicone based Softners. In this era the element carbon has been replaced by element silicone. They contain the basic silicone backbone called siloxanes (Si-O-Si). The earlier days silicone products were based on linear structures, called dimethyl amino siloxanes and molecular weight in 400-500 gm/mole and represented as, NH2-CH2-CH2-SiCH3H-O-SICH3H-CH2-CH2-OCH3. The amino groups are at one terminal and ending at methoxy. However, latest research used D4 tetrasiloxanes with ether linkage and hindered amine. The molecular weight goes to 100,000 gm/mole, reflecting extreme high degree of polymerization. The ether linkage provides hydrophilicity and the hindered amine provides softness. Some of these silicone emulsions, are shear stable, non-yellowing, suitable for both exhaust and continuous usage and complete non-ionic in nature allows them for use in both white and dyed.
NOTE: A simple test to check shear stability is to heat the silicone emulsion around 90-100C and observe phase separation. The oil if breaks from the emulsifier and two distinct layers are seen. Then, the silicone emulsion is not heat stable, and should be avoided using in exhaust and in high shear systems.
For the towel industries, where requirement is high absorbency and softness we offer, three silicone nano emulsions.
1. Advasil LT-40
Customers kindly select this product if absorbency or retention is not the requirement rather high softness with slippery touch is required.
2. Advasil TW-40
This gives extremely high absorbency or retention. The softness is not so great.
3. Advasil LH-50
This is a blend of Advasil LT-40 Conc. & Advasil TW-40. Customers normally at dosage of 10g/l achieve desired softness and absorbency. However, to achieve high retention requirement we recommended use of Advasil TW-40 to along with Advasil LH-50 to achieve desired absorbency. The starting recipe could be
Advasil LH-50 ---->5 g/l
Advasil TW-40 ---->05 g/l
Note: Advasil TW-40 will retain retention of the towel as achieved after bleaching or dyeing. Its increase dosage will not hamper the absorbency. So, for optimum softness and absorbency requirements, we suggest use of Advasil LH-50 and Advasil TW-40. An starting recipe could be Advasil LH-50 5 gm/l Advasil TW-40 20 gm/l So, in order to meet the requirements of both softness and hydrophilicity the complete Advasil range of LT-40, LH-50, and TW-40 must be kept, inorder to best required results at affordable cost.
