DDAC (40% aqueous in both radiolabled (14C) and nonradiolabled form), used in a definitive pharmacokinetic study to determine absorption, distribution and excretion and was administered orally (single dose), by gavage, to Charles River CD (Crl CD(SD)Br--5/sex/group) ... . In the addendum the metabolic profile was determined in a 2 step experiment. First, another group of rats (10 male Charles River CD (Crl CD(SD)Br) were treated with (14C)-DDAC at 50 mg/kg in order to obtain enough (14C) residues to use as standards. The (14C) metabolites were characterized by TLC, HPLC and MS. The second part of the experiment involved using the "standard" metabolic profiles to analyze the metabolites from feces samples obtained in the initial study. It was shown that metabolism tends to be sex specific. Females metabolize the parent compound more so than males. Metabolism, which may be microbial in nature, involved the oxidation of the 2 decyl side chains to form hydroxy and hydroxyketo derivatives. Modification of methyl substituents was not evident.
IDENTIFICATION AND USE: Didecyl dimethylammonium chloride is a clear yellow liquid with an ethanolic odor. It is used as an algaecide, bacteriocide, fungicide, fungistat, microbiocide, microbiostat disinfectant, viricide, tuberculocide, molluscide, sanitizer, wood preservative, deodorant, and insecticide. It has been tested for treatment of impetiginized eczema patients in combination with prednicarbate. HUMAN EXPOSURE AND TOXICITY: Nausea, headache, and sore throat are the primary systemic effects that have been reported. The primary dermal effects that have been reported are rash, burning sensation, numbness, and itching. A case report of dermatitis from detergent/disinfectant was described. A 24 year old woman, who had worked in a hospital for 2 years, presented with a 2 month history of dermatitis of the dorsum of the hands and wrists. Patch testing showed she was positive for didecyldimethylammonium chloride and bis-(aminopropyl)-laurylamine which was present in detergents/disinfectants. According to the EPA classification didecyl dimethylammonium chloride is not likely to be carcinogenic to humans. ANIMAL STUDIES: In animals it is a severe eye irritant, severe dermal irritant, but not a sensitizer. It was of moderate acute oral toxicity in rodents, with possible effects on the liver and central nervous system being seen. In rats no adverse oncogenic effects were observed, however, there were treatment-related changes in both sexes in the mesenteric lymph node (blood filled sinuses, hemosiderosis and hystiocytosis) and bile duct hyperplasia at 1500 ppm. There were no developmental effects in rats. In developmental study in rabbits an increased number of dead fetuses/litter and decreased fetal body weight at 10.0 mg/kg was observed. In the Ames test, with or without the microsomal activation (S-9 fraction), didecyl dimethylammonium chloride was not mutagenic to Salmonella typhimurium tester strains. It was not mutagenic in vivo in rats, in Chinese hamster ovary cells, and did not produce unscheduled DNA synthesis. ECOTOXICITY STUDIES: Swimming performance decreased significantly in juvenile rainbow trout. Significant decreases in larval growth and survival were noted at all tested concentrations and in all sturgeon age groups. The larval stage was usually more sensitive than the fry stage. Acute toxicity tests with fertilized eggs were unsuccessful. Developmental stage altered the sensitivity of coho salmon to Bardac 2280, with alevins being approximately twice as sensitive as smolts.

The bactericidal activity of a quaternary ammonium salt, didecyldimethylammonium chloride (DDAC), was depressed by the presence of soap, sodium laurate (NaLA): the minimum lethal concentration (MLC) of DDAC against Staphylococcus aureus was 63 and 250 ug/mL in the absence and presence of 0.01% NaLA, respectively. The neutralizing effect was studied in relation with the mode of action of DDAC. The apparent uptake of DDAC by the cell was not repressed by NaLA's presence when compared to that in its absence. The solution of NaLA showed alkaline pH, but the biocidal activity of DDAC was higher at pH 11 than at pH 7. Although the presence of NaLA had no significant effect on DDAC's action on increasing the turbidity of the cell suspension, the mixture of these reagents alone without cells exhibited some turbidity. From these findings it is deduced that NaLA can form a less active complex with DDAC by both ionic and hydrophobic interactions...
/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Poisons A and B/

Excretion of radioactivity was shown to occur primarily in the feces (89-99%), some in urine (<2.5%), and an insignificant amount was expired. Highly ionic DDAC is not readily absorbed from the GI tract...

Modeling of Multiple Equilibria in the Self-Aggregation of Di-n-decyldimethylammonium Chloride/Octaethylene Glycol Monododecyl Ether/Cyclodextrin Ternary Systems
摘要：
The surface tension equations of binary surfactant mixtures (di-n-decyldimethylammonium chloride and octaethylene glycol monododecyl ether) are established by combining the Szyszkowski equation of surfactant solutions, the ideal or nonideal mixing theory, and the phase separation model. For surfactant mixtures, the surface tension at the air water interface is calculated using nonideal theory due to synergism between the two adsorbed surfactant types. The incorporation of cyclodextrin complexation model to the surface tension equations gives a robust model for the description of the surface tension isotherms of binary, ternary, and more complex systems involving numerous inclusion complexes. The surface tension data obtained experimentally shows excellent agreement with the theoretical model below and above the formation of micelles. The strong synergistic effect observed between the two surfactants is disrupted by the presence of CDs, leading to,ideal behavior of ternary systems. Indeed, depending on the nature of the cyclodextrin (i.e., alpha, beta, or gamma), which allows a tuning of the cavity size, the binding constants with the surfactants are modified as well as the surface properties due to strong modification of equilibria involved in the ternary mixture.
