Additional information

Reproductive toxicity study

Data available from different studies were reviewed to determine the reproductive toxicity of1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts .The studies are as mentioned below:

Study 1

The 90 days subchronic toxicity study of 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-(C12-18(even numbered) acyl) derivs., hydroxides, inner salts was performed according to OECD TG 408 on male and female Sprague-Dawley rats. The test material dissolved inin distilled water at dose levels of 0, 250, 500 or 1000 mg/kg-day and administered via oral gavage route once a day for5 days/week in dose volume 10ml/kg bw .10/sex/dose was used in the study. All the animals were observed for Clinical signs and mortality daily. Body weight and food consumption were noted twice a week. On day 92, All the animals were sacrifice and Gross pathology and Histopathology were performed. There were no treatment-related mortalities in any test group. No effects on Body weight and food consumption were noted. No effects on testes and ovaries weights. No treatment related effects on histopathology of testes, accessory sex organs, ovaries, uterus, prostate were noted. Hence No Observed Adverse Effect Level (NOAEL) for reproductive toxicity was considered to be 1000 mg/kg/day, as no effects on reproductive organ weight and histopathology, When male and female Sprague Dawley rats were treated with 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-(C12-18(even numbered) acyl) derivs., hydroxides, inner salts orally for 90 days.

Study2.

The prenatal developmental toxicity study following OECD guideline 414 was performed on female CD rats. Test material soluble in water(aqua ad iniectabilia) in dose concentration0, 330, 990 or 3300 mg/kg-day (corresponding to 0, 95, 286, and 950 mg/kg-day active substance, respectively) administered in dose volume 10 ml/kg bw from day 5 to 19 of pregnancy once daily via gavag.25 female rats /dose group were treated; 20 pregnant animals were evaluated; 20 (0, 330, 990 mg/kg bw group) and 21 (3300 mg/kg bw group) were evaluated for maternal toxicity. 1 male and 1 female were placed in one cage during the dark period. Mating was repeated until vaginal smear showed presence of sperm. All animals were observed for clinical signs, Body weight and food consumption daily. Also No. fetuses alive, Weight of fetuses, sex distribution of fetuses, skeletal anomalies (50 %) and soft tissue anomalies (50 %) were noted. One dam at 3300 mg/kg day died on gestation day 15 and in same dose group 13/21 abdominal position, 2/21: pilo-erection, reduced motility was noted. >= 990 mg/kg bw dose group reduction of the net weight change (carcass weight minus day 6 body weight) from day 6 onwards (23% and 67%). At 3300 mg/kg bw dose group reduced body weight (up to 17 % below control) and decreased body weight change were observed. >= 990 mg/kg bw dose group reduced food consumption (up to 12 % gestation days 8, 10, 19)and at 3300 mg/kg bw dose group up to 65% each day. In 3300 mg/kg bw dose group reduced gravid uterus weight by 22% (caused by lowered fetal weights).At 990mg/kg bw dose group 4/20: ulcers, thickened mucosa and in 3300 mg/kg bw dose group 20/21: thickened mucosa, greyish discoloured in 2/21; ulcers (also in the prematurely deceased dam) were observed. The number of early, late and total resorptions was increased in the 3300 mg/kg bw group. Moreover the ratio of viable fetuses to implantation sites was decreased compared to the controls. This was due to a total post-implantation loss of two dams in this dose group. A statistically significant reduction in fetal weights and number of viable fetuses as compared to the control was observed At 3300 mg/kg bw dose group. No external, skeletal or soft tissue malformations and no external variations were seen in controls or in dosed groups. The fetal incidence of the skeletal variations was 5 in the controls and 8 (330 mg/kg bw), 13 (990 mg/kg bw) and 6 (3300 mg/kg bw). The finding in the 990 mg/kg bw group was judged as incidental as no dose-relationship was noted. The skeletal retardations (fetal incidence) were 129 in the controls and 137 (330 mg/kg bw), 130 (990 mg/kg bw) and 125 (3300 mg/kg bw) in the dosed groups. No dose-related soft tissue variations were observed, as seen in the following fetal incidences: 8 (control), 12 (330 mg/kg bw), 10 (990 mg/kg bw) and 9 (3300 mg/kg bw). Hence The NOAEL for maternal toxicity was 95 mg/kg bw/day and the NOAEL for reproductive and developmental toxicity was >950 mg/kg bw/day as the post-implantation loss and decreased mean foetal bodyweight were considered to be secondary to maternal toxicity. When female CD were treated with 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-(C12-18(even numbered) acyl) derivs., hydroxides, inner salts orally from day 5 - 19 of pregnancy.

Study 3

 

In a 28 days repeated dose toxicity study, the effect of test material was evaluated in male and female Sprague Dawley rats. The test chemical was administered by oral gavage in the concentration of 0, 250, 500 and 1000 mg/kg/ body weight/day. The results showed no effect on mortality, no changes were in food consumption and ophthalmology. Changes were observed in clinical signs like softstool, nasal discharge, red crust round nostrils, perineum soiled with fecal matter. Significant decreased were observed in water consumption and locomotor activity of female rat in1000 mg/kg dose group. Bodyweight was increased significantly in male and female rats. Significant changes were observed in the level of testosterone, sodium, total proteins, total cholesterol, SGOT, SGPT, albumin, Blood urea nitrogen (BUN) and Creatinine when treated with 500 and 1000 mg/kg/day. Significant changes were observed in absolute and relative weight of brain, adrenals, spleen, thymus, epididymides, heart, kidneys, ovaries, uterus and liver in 500 and 1000 mg/kg/day. In addition, minimal to mild gross pathological and histopathological changes were observed in liver, spleen and intestine. However, the biological significance of these findings are not related to test chemical. Therefore, NOAEL was considered to be 1000 mg/kg/day when Sprague-Dawley rat exposed to test substance orally.

Based on the data available from different studies,1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-(C12-18(even numbered) acyl) derivs., hydroxides, inner saltsdid not showedreproductive toxicityat dose concentration 1000mg/kg bw/day.Hence the test chemical is not likely to classify as a reproductive toxicant as per the criteria mentioned in CLP regulation.

No external, skeletal or soft tissue malformations and no external variations were seen in controls or in dosed groups. The fetal incidence of the skeletal variations was 5 in the controls and 8 (330 mg/kg bw), 13 (990 mg/kg bw) and 6 (3300 mg/kg bw). The finding in the 990 mg/kg bw group was judged as incidental as no dose-relationship was noted. The skeletal retardations (fetal incidence) were 129 in the controls and 137 (330 mg/kg bw), 130 (990 mg/kg bw) and 125 (3300 mg/kg bw) in the dosed groups. No dose-related soft tissue variations were observed, as seen in the following fetal incidences: 8 (control), 12 (330 mg/kg bw), 10 (990 mg/kg bw) and 9 (3300 mg/kg bw). Hence the NOAEL for maternal toxicity was 95 mg/kg bw/day and the NOAEL for developmental toxicity was >950 mg/kg bw/day as the post-implantation loss and decreased mean foetal bodyweight were considered to be secondary to maternal toxicity. When female CD were treated with 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-(C12-18(even numbered) acyl) derivs., hydroxides, inner salts orally from day 5 - 19 of pregnancy.

Developmental toxicity study

Data available for the read across chemicals was reviewed to determine the developmental toxicity of

1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-(C12-18(even numbered) acyl) derivs., hydroxides, inner salt.The studies are as mentioned below:

Study 1

The prenatal developmental toxicity study following OECD guideline 414 was performed on female CD rats. Test material soluble in water(aqua ad iniectabilia) in dose concentration0, 330, 990 or 3300 mg/kg-day (corresponding to 0, 95, 286, and 950 mg/kg-day active substance, respectively) administered in dose volume 10 ml/kg bw from day 5 to 19 of pregnancy once daily via gavag.25 female rats /dose group were treated; 20 pregnant animals were evaluated; 20 (0, 330, 990 mg/kg bw group) and 21 (3300 mg/kg bw group) were evaluated for maternal toxicity. 1 male and 1 female were placed in one cage during the dark period. Mating was repeated until vaginal smear showed presence of sperm. All animals were observed for clinical signs ,Body weight and food consumption daily. Also No. fetuses alive, Weight of fetuses, sex distribution of fetuses, skeletal anomalies (50 %) and soft tissue anomalies (50 %) were noted. One dam at 3300 mg/kg day died on gestation day 15 and in same dose group 13/21 abdominal position, 2/21: pilo-erection, reduced motility was noted. >= 990 mg/kg bw dose group reduction of the net weight change (carcass weight minus day 6 body weight) from day 6 onwards (23% and 67%). At 3300 mg/kg bw dose group reduced body weight (up to 17 % below control) and decreased body weight change were observed. >= 990 mg/kg bw dose group reduced food consumption (up to 12 % gestation days 8, 10, 19)and at 3300 mg/kg bw dose group up to 65% each day. In 3300 mg/kg bw dose group reduced gravid uterus weight by 22% (caused by lowered fetal weights).At 990mg/kg bw dose group 4/20: ulcers, thickened mucosa and in 3300 mg/kg bw dose group 20/21: thickened mucosa, greyish discoloured in 2/21; ulcers (also in the prematurely deceased dam) were observed. The number of early, late and total resorptions was increased in the 3300 mg/kg bw group. Moreover the ratio of viable fetuses to implantation sites was decreased compared to the controls. This was due to a total post-implantation loss of two dams in this dose group. A statistically significant reduction in fetal weights and number of viable fetuses as compared to the control was observed At 3300 mg/kg bw dose group. No external, skeletal or soft tissue malformations and no external variations were seen in controls or in dosed groups. The fetal incidence of the skeletal variations was 5 in the controls and 8 (330 mg/kg bw), 13 (990 mg/kg bw) and 6 (3300 mg/kg bw). The finding in the 990 mg/kg bw group was judged as incidental as no dose-relationship was noted. The skeletal retardations (fetal incidence) were 129 in the controls and 137 (330 mg/kg bw), 130 (990 mg/kg bw) and 125 (3300 mg/kg bw) in the dosed groups. No dose-related soft tissue variations were observed, as seen in the following fetal incidences: 8 (control), 12 (330 mg/kg bw), 10 (990 mg/kg bw) and 9 (3300 mg/kg bw). Hence the NOAEL for maternal toxicity was 95 mg/kg bw/day and the NOAEL for developmental toxicity was >950 mg/kg bw/day as the post-implantation loss and decreased mean foetal bodyweight were considered to be secondary to maternal toxicity. When female CD were treated with 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-(C12-18(even numbered) acyl) derivs., hydroxides, inner salts orally from day 5 - 19 of pregnancy.

Study2.

 

The developmental toxicity study of1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-(C12-18(even numbered) acyl) derivs., hydroxides, inner salts was performed on female pregnant rats. The test material was administered in dose concentration 0, 30, 90 or 300 mg/kg bw on days 6 through 17 of gestation via gavage. Clinical signs, gestational body weights, food consumption, gravid uterine weight, total number of corpora lutea, implantation, early and late resoptions, were noted in dams while live and dead fetuses, sex, individual body weights of fetuses ,visceral (50 %) and skeletal (50 %) abnormalities were observed in fetuses .No treatment-related effects on the incidence of fetal external, visceral, or skeletal malformations or developmental variations were observed among litters from dams in any of the treated groups. Hence the maternal and developmental no-observed-effect level (NOEL) was considered to be 300 mg/kg bw/d, the highest level, When female rats were treated with 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-(C12-18(even numbered) acyl) derivs., hydroxides, inner salts orally on days 6 through 17 of gestation.

Study 3

Combined Repeat Dose and Reproductive / Developmental Toxicity Screening Test of test material were performed on male and female Sprague Dawley rats. The test material was suspended in corn oil in dose concentration0 ,100, 300 and 1,000 mg/kg bw/day and administered via oral gavage route in dose volume 5ml/kg bw. Dose selected on the bases ofpreliminary test by the previously repeated 14-day oral administration. 13 male and 13 female each were placed in each group. Administration period For each males, 2 weeks before mating, and 42 days from the end of the mating period to the day before the necropsy for males, and for female 2 weeks before mating and a maximum of 2 weeks mating period (Until mating) and once daily for the entire gestation period and 3 days after nursing (delivery day = nursing 0 day) in mating females. Matings were made with the same sex of the same group living together within the same group for up to two weeks from the evening on 15th day of administration. Mating was confirmed every morning by examining the presence of sperm in the vaginal plug and vaginal smear and females confirmed to be mated were separated from male starting from that day as the 0th day of pregnancy and raised individually. All the animals were observed for clinical signs, body weight and food consumption.

No deaths in male and female were observed. In males, no abnormalities in general conditions were observed. In females, there was only one change from day 42 of administration (day of delivery) to the one in 100 mg / kg administration group (administration 42 days: piloerection, blood-like fluid discharge from the vaginal opening; administration 43 to 44 days: coat contamination) But it recovered on day 45 of administration. In other females, no abnormalities in the general condition were observed. In male, the body weight gain increased from 8 to 15 days in the 100 mg / kg administration group significantly (p <0.01) compared with the control group, However, in the group administered with 300 mg / kg or more, there was no significant difference between the control group and treated group. In females, there was no significant difference in body weight and body weight gain between control group and treated group before breeding, pregnancy period and nursing period. There was no significant difference between the control group and treated group for males and female at any time of feeding intake. There was no significant difference between the control group and treated group in the mating rate, conception rate, the number of days taken from the start of cohabitation to mating and the number of estrus periods recurred during that period.

An abnormality in labor condition (not treated with placenta) and abnormality in nursing condition (not collecting children, poor protrusion of nipple, poor protrusion of infant, child's fetus) was administered to one of 100 mg / kg administration group, The decrease in body surface temperature) was observed, and all children died on nursing day 2, but no abnormality was observed in other mother animals. For male In the 100 mg / kg administration group, the actual weight and the specific body weight value of the liver increased significantly (p <0.05) compared to the control group, but not the dose-dependent change. Atrophy of seminiferous tubules was found in 2 animals in the 1000 mg / kg administration group, one on both sides and one on one side, but both were localized and extremely mildly changed. There were no other abnormalities. Sperm granuloma was observed in one of the control group, and there was no abnormality. There were no abnormalities in the ovaries of the unexpanded and infertile cases. For female In the 100 mg / kg administration group, the actual weight of the kidney decreased significantly (p <0.05) compared to the control group, but not the dose-dependent change. For other organs in male and female, no significant difference was observed between the control group and treated group. Birth rate was 100% in all administration groups, and no significant difference was observed between gestation period between control group and treated group. No significant difference was observed between the control group and treated group for the number of luteinism, the number of implantation and the implantation rate of pregnant animals. There was no significant difference between the control group and treated group for the number of births, delivery rate, birth rate, fertility rate, and survival rate on 4th day of new born. In addition, no significant difference was observed between the control group and treated group for sex ratio. There was no significant difference between the control group and the treated group on body weight at 0 and 4 days of nursing. Births that showed morphological abnormalities were not observed in the external table observation on the birthday, necropsy of the dead child, and necropsy on the 4th day of nursing. Hence No Observed Adverse Effect Level (NOAEL) for reproductive and developmental toxicity was considered to be 1000mg/kg bw .When male and female Sprague Dawley rats were treated with test material orally.

Based on the data available from different studies,1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-(C12-18(even numbered) acyl) derivs., hydroxides, inner saltsdid not showed developmental toxicityat dose concentration between 300- 1000mg/kg bw/day.Hence the test chemical is not likely to classify as a reproductive and developmental toxicant as per the criteria mentioned in CLP regulation.

 

Justification for classification or non-classification

Thus, comparing this value with the criteria of CLP regulation 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts not likely to classify as reproductive and developmental toxicant.
