Properties
GB-DH301 can be applied by solution or emulsion. Most textile processes are water-based. Hence it is
mainly applied from emulsion.
GB-DH301 is highly suitable for the formulation of micro emulsions and macro emulsions.
GB-DH301 can be used as sole active substance in softener emulsions or in combination with other
components, e.g. paraffines, esters of fatty acids, etc. Compatibility of the components should be checked in
each individual case.
Nonionic EMULSIFIERs are recommended to get a stable micro emulsion based on GB-DH301 to be
prepared with the minimum of shear force.
Emulsions of GB-DH301 are diluted to the optimum concentration for the specific fabric. They are
applied by padding or exhaustion and give fabrics a special soft touch.

Field of Application
GB-DH301 is particularly suitable as an active substance in softener formulations for the impregnation
of fibers and fabrics.
GB-DH301 imparts a very soft, smoothness, and elastic handle to woven and knitted fabrics.
GB-DH301 is considered to be the best softening agent for cotton. cotton/PES blends fabrics , especial
for knit cotton.
GB-DH301 has very little effect on the degree of whiteness or color change in a softener formulation under
usual application conditions.

Process Recommended
1. Stir GB-DH301 and emulsifiers until well mixed;
2. Dissolve glacial acetic acid in water (20% glacial acetic acid Concentration will be better for usage),
    and charge into the mixture;
3. Slowly add the deionized water to the mixture of GB-DH301 and emulsifier, and increase mixing
    speed.
    The deionized water is recommended charge step by step, such as 5%(as the first charge
    consumption), 5%, 10%,10%, 20% and the residual.
    Keep stirring for every step water added until mixture is homogeneous, and try to avoid too much
    air was stirred into the emulsion.
4. Packed into barrels after filtration.
