CBS-X
Optical Brightener
C.I.351, 4,4'-Bis(2-Disulfonic Acid Styryl) Biphenyl
27344-41-8
562.6
C28H20S2O6Na2
3204200000
Appearance: yellow or yellowish green powder or granular
Solubility: soluble in water
Characteristic:
1. CBS-X is a disulfonic distyrylbiphenyl compound, has better brighten intensity on cotton cloth as much as 2.7 times as bis(triazinylamino) stilbene derivatives, and has good optical blue color monitor, dissolve and disperse properties
2. CBS-X has good dispersing ability when dissolving, and stable in the solution of sodium hypochlorite, so it's compatible with detergent with bleaching agent
3. CBS-X is environmental friendly, considering the small dosage in the detergent system, the residue on fabrics is very limited, and it can be light degraded and biodegraded easily. Different tests proved that CBS-X will not accumulated in fishes' organs
4. CBS-X is non-toxic and no harm to human, and no irritation to skins either

1. There are more than 5000 brighteners on the world market, they are actually different brand names and numbers from different producers/ distributors for less than 400 chemical compounds. On China's market, the main names/ types are: BBU, CXT, BA-L, BA, APC, DMS(AMS), MST, 210, VBL, BBU, DT, VBU, BA, BC, DMS, FB-351, CBS-L, BA-L, 31#, CBW, 5BM, OB-1, APC, VBL, CXT, BBC, BST, BC-100, ER, ERI, BBU, CBS-L, PS(PF), OB, KB, OB-1, KCB, KSN, DBH-1, APH, APB-L, ER, KCB, KSN, PF, NFW, HPE and etc.
2. CBS-X has better performance when applicating together with optical brightener DMS
3. We normally list 12 months as the shelf life in our COA, the real shelf life can be slightly longer than 12 months if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials), but it's still suggested to avoid long time storage
