Usage

Uses

Used in Personal Care Industry:
1-Tetradecylpyridinium chloride is used as a deodorant agent for its ability to neutralize and eliminate unpleasant odors. It is particularly effective in controlling body odor caused by bacterial activity on the skin.
Used in Hygiene Products Industry:
1-Tetradecylpyridinium chloride is used as a key component in the preparation of super absorbent resins. These resins are specifically designed to remove and control adult urine odor in hygiene products such as adult diapers and incontinence pads. 1-Tetradecylpyridinium chloride's antimicrobial properties help to prevent the growth of odor-causing bacteria, while its affinity for hydrophobic substances aids in the absorption and retention of urine.

Binding of N-Alkylpyridinium Chlorides to Nonionic Micelles

Binding of N-alkylpyridinium chlorides (C10, C12, and C14) to dodecyl oxyethylene ether (C12E6 and C12E8) micelles is determined in the presence of 5 mol m-3 NaCl at various temperatures by potentiometry which employs an electrode responsive to the surfactants.Binding affinity is expressed in terms of a distribution coefficient, Kx, of a cationic surfactant between the aqueous bulk phase and the nonionic micellar phase, and is larger for an alkylpyridinium cation with a longer hydrocarbon chain.The values of Kx are divided into three regions depending on the mole fraction of bound cationic surfactant in a micelle, X.At X x remains constant, while for 0.02 0.2.The constant Kx values reflect an intrinsic binding affinity (K0).With increase in X, electrostatic repulsion among bound cationic surfactants causes decreased Kx values, which may be analyzed by a simple electrostatic theory to estimate the position of bound cationic head groups.From the temperature dependence of K0, it is found that the binding process is nearly athermal for C12E8 micelles but exothermic for C12E6 micelles, the latter associated with the growth of micellar size with temperature.

Tenside mit perfluorierten Gegenionen: Systeme mit ungewoehnlichen Eigenschaften

Conductivity measurements, kinetic investigations with relaxation techniques, static and dynamic light scattering, electric birefringence and rheological measurements were carried out on aqueous solutions of Tetradecylpyridinium-perfluorbutyrate.The measurements show that spherical micelles with an aggregation number of about 70 are formed above the critical micelle concentration (cmc).The cmc-value is about one order of magnitude lower than the cmc of Tetradecylpyridiniumchloride which is due to strong association of the hydrophobic counterions to the micelles.Above a transition concentration ct which at 25 deg C is about three times higher than the cmc, the spherical micelles begin to grow to rodlike aggregates.The lengths of these rods increase with increasing detergent concentration and reach a maximum value, when the rotational volumes of the rods begin to overlap.Above this concentration strong repulsive interaction between the aggregates takes place which gives rise to a drastic increase of the translational diffusion coefficients, to an increase of the activation energy for viscous flow and to the appearance of nonexponential decay of the transient electrical birefringence.The refractive index increments dn/dc for solutions of surfactants consisting of hydrocarbon and perfluorhydrocarbon parts were found to decrease linearly with increasing chainlength of the perfluorated part in the surfactant molecule.The electric birefringence depends strongly both on the temperature of the solutions and on the wavelength of the light used for the detection.The birefringence is negative at room temperature and the amplitude decreases also with increasing temperature and disappears above 70 deg C; surprisingly the amplitude decreases also with decreasing temperature, vanishes at 16 deg C and becomes finally positive below this temperature.An analoguous behaviour is observed at constant temperature when the wavelength of the incident light is changed; the birefringence is negative at long wavelengths, the amplitude decreases with decreasing wavelength and becomes positive below a certain wavelength.This behaviour was assumed to be due to a fortuitous compensation of the form birefringence and the intrinsic birefringence in this system.The dn/dc-values seem to play a deciding role for this compensation, because the homologuous surfactant compounds with similar dn/dc-values give the same electrooptic behaviour. - Keywords: Detergents / Hydrophobic counterions / Micelles / Electric birefringence / Refractive index increment
