19959-22-9 Usage
General Description
Dodecyldimethylammonium bromide, commonly known as dodecylbenzenesulfonic acid, is a quaternary ammonium salt. dodecyldimethylammonium bromide is used in numerous ways commercially, most common for its antibacterial, antifungal, and antiviral properties. It is a significant component in many disinfectants and sanitizers. In the cosmetic industry, it serves as a conditioning agent for hair and skin products. However, it is also deemed hazardous due to its irritative effect on skin, eyes, and the respiratory system. Adequate protective measures must be undertaken while handling this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 19959-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,5 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19959-22:
(7*1)+(6*9)+(5*9)+(4*5)+(3*9)+(2*2)+(1*2)=159
159 % 10 = 9
So 19959-22-9 is a valid CAS Registry Number.

Effect of the surfactant head-group size dependence of the dye-surfactant interactions on the lyotropic uniaxial to biaxial nematic phase transitions

In the present study, the interactions of the anionic azo dye Sunset Yellow with dodecylalkylammonium bromide (DAABr) surfactants in lyotropic mixtures have been investigated for the stabilization of the different lyotropic nematic phases. Sunset Yellow doped mixtures of DAABr surfactants, with different head-group size, were studied by polarizing optical microscopy, laser conoscopy, and small-angle X-ray scattering. It was found that the extent of the interaction of Sunset Yellow with DAABr surfactant head groups on micelle surfaces affects the stabilization of different nematic phases, by causing the change in the micellar structural parameters. The results also indicated that the micelle surface curvature should be different in the three nematic phases.
