The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place. |

| TSCA Test Submissions | 3-Dimethylaminopropylamine (CAS # 109-55-7) was evaluated for subchronic oral toxicity in groups of Wistar rats (5/sex/group) administered doses of 0, 10, 50, and 250 mg/kg-day by oral gavage for 28 days. Due to a high rate of mortality (3/5) among the 250 mg/kg females during the initial study, a second trial in 5 female rats receiving 250 mg/kg was conducted with data combined for 10 high-dose females. All animals were necropsied on the 29th day of study. Females of the high dose group only (4/10) died during the 28-day treatment period. Clinical signs, observed intermittently in this group between study days 11 and 24 and mainly among the intercurrent decedents, included hypoactivity, stilted gait, swollen abdomen, and labored breathing. A solitary high-dose male demonstrated impaired respiration. Bodyweights, organ weights, food and water consumption, urinalyses, and hematological and clinical chemistry evaluations did not deviate significantly from those of controls in any dose group. Upon necropsy, discolored lungs with surface red spots and foamy content, and a solitary small spleen characterized the gross pathology, identified solely in the decedent females. Microscopic examination revealed distinct lesions among these animals, which included organ congestion, hemorrhagic and/or edematous lungs, and profound loss and atrophy of splenic lymphatic follicles and lymphoid sheath, respectively. One symptomatic male of a 250 mg/kg dose group exhibited focal epithelial degeneration of the forestomach which authors claimed was likely due to an irritative effect of the compound.N,N-Dimethyl-1,3-propanediamine (CAS # 109-55-7) was evaluated for dermal sensitization in 15 female Hartley guinea pigs by maximization test. Induction consisted of 3 pairs of 0.1 mL intradermal injections flanking the dorsal midline upon the clipped shoulder area, the respective twin injections including a 1-5% v/v solution in distilled water (unspecified pretest concentration that produces neither local or systemic reactions), a 1-5% v/v solution in Freunds Complete Adjuvant (FCA), and FCA alone. Following the 7-day induction, 48-hour challenge was administered with a 0.3 mL topical application of 1% solution in distilled water under occluded patch covering the entire test area. A second 48-hour challenge was performed 21 days later with a 0.3 mL topical application of 5% solution and another of vehicle alone, each on either side of the dorsal midline to cover triplet test sites. Although pretest irritation results were not provided, the authors concluded that positive reaction in 93% (14/15) of the test animals, relative to 0% response (0/6) in the vehicle/FCA control group and 100% response in the dinitrochlorobenzene (positive control) group following 5% N,N-dimethyl-1,3-propanediamine second challenge, established a maximization grading of "extreme" sensitization. |

Anwendungen & Verwendung
Beschreibung
Dimethylaminopropylamine is an aliphatic amine present in amphoteric surfactants such as liquid soaps and shampoos. It is present as an impurity responsible for allergy from cocamidopropylbetaine. It is structurally similar to diethylaminopropylamine. It is also used as a curing agent for epoxy res ins and as an organic intermediate in chemical syntheses (ion exchangers, additives for flocculants, cosmetics and fuel additives, dyes and pesticides).
Verwenden
N,N-Dimethyl-1,3-propylenediamine is a useful catalyst for Knoevenagel condensation. It is also a useful hardening agent for expoxy resin.
