Optical Brightener DMS is regarded as one of the perfect agent used
in detergent industry. Owing to introducing the morpholine group
into the molecular, the properties such as acid and perborate
resistance be improved. It can be used in the whitening of
cellulose fiber, polyamide fiber and fabrics, showing anionic
characters and has optical blue color. It has better resistance to
chloride beeaching than VBL and 31*, the most favorable dyeing bath
PH value is 7-10. Its sunlight fasiness is 4 grades. The most
advantage used in detergent industry is its high matching capacit,
high accumulated washing whitening effect. So it can meet the
requirements of any matching capacity in detergent industry.
- Used in detergent industry, for the synthetic detergent, toilet
soap and soap.
- Used in the fabric of cotton fiber,nylon,etc,taking on excellent
whitening effect on artificial fiber, polyamide,vinylon,also has
good whitening effect on protein fiber, aminoplastics.
Optical brightener DMS has less solubility than VBL and 31*, it can
be soluble in hot water and form about 10% suspension liquid. The
liquid should be used immediately when ready and avoid sunlight.
The dosage used is 0.1-0.5% in detergent industry and 0.1-0.3% in
Packed in cardboard bucket or carboard box after being firstly
packed in plastic bag. Net weight perbucket is 20kg or 25kg.
TRANSPERTATION: Should avoid sunlight and crash.
STORAGE: Should be stored in cool, dry and ventilate place, and
storage time should not exceed 2 years.
