Sodium Carbonate

The Basics On Sodium Carbonate

What is Sodium Carbonate?

Absorbent salt used in cosmetics; it can also be a skin sensitizer.

What are other names for Sodium Carbonate?

BISODIUM CARBONATE, CARBONIC ACID DISODIUM SALT, CARBONIC ACID, DISODIUM SALT, DISODIUM SALT CARBONIC ACID, SODA ASH, SODIUM CARBONATE, and SODIUM CARBONATE; SODIUM CARBONATE

What is Sodium Carbonate used for?

Sodium carbonate breaks down dirt and oil from the hair and skin and helps to regulate the pH of our products. Commonly known as washing soda, this white odorless powder softens water and helps to break down dirt and oil.

How Sodium Carbonate is classified

Absorbent, Sensitizing

The reproductive and developmental toxicity of magnesium chloride hexahydrate was studied using groups of Wistar rats. 25 The dose groups were as follows: 250 mg/kg body weight/day (10 males, 10 females), 500 mg/kg body weight/day (12 males, 12 females), and 1000 mg/kg body weight/day (15 males, 15 females). The vehicle (water) control group consisted of 12 males and 12 females. The test substance was administered orally (by gavage) to males and females daily during 14 days pre-mating and 14 days of mating. The test substance was also administered to females during gestation and up to PND 3, and to males for 28 to 29 days. No test substance-related histopathological lesions were observed in the reproductive organs of male or female rats dosed with the test substance (all dose groups). There were no treatment-related effects with respect to the following when compared to controls: mean number of corpora lutea, number of implantation sites, total number of pups born, number of males, number of females, sex ratio, live pups, still birth, runt on PND 0, and total number of live pups and sex ratio on PND 4, pre-implantation loss and post-implantation loss. The survival of pups (in all treatment groups) from PND 0 to PND 4 was not affected by treatment. At necropsy, there were no gross external abnormalities in pups from any dose group. It was concluded that the NOAEL for reproductive/developmental toxicity of magnesium chloride hexahydrate was 1000 mg/kg body weight. Furthermore, it was determined that the equivalent NOAEL for Magnesium Carbonate was 414 mg/kg body weight/day. Additonal results from this study are included in the Short-Term Oral Toxicity section of this report. The teratogenicity of magnesium chloride hexahydrate (in distilled water) was evaluated using groups of 22 pregnant female Wistar rats. 25 The 3 dose groups received oral doses (by gavage) of 200, 400, and 800 mg/kg/day, respectively, on gestation days 6 to 15 (10 days). A fourth group served as the control. The animals were killed on day 20 of pregnancy. Regarding maternal toxicity, there were no clinical signs or deaths. Dosing (all groups) did not cause increased incidences of the following: number of implantations, number of corpora lutea, % implantation loss, number of offspring alive, sex ratio of offspring, offspring weight or embryo/intrauterine fetal death. Gross malformation was observed in the dose groups, but without any intergroup differences. Bone malformation was observed in one fetus of the 800 mg/kg/day dose group. There were no intergroup differences in bone abnormality, effects on lumbocostale, extra ribs, sacrococcygea, metacarpal bone or its ossification. Visceral malformations were observed in 4 to 6 fetuses from each dose group, but without intergroup differences. It was concluded that magnesium chloride hexahydrate was not teratogenic in rats dosed by gavage. The NOAEL was estimated to be > 800 mg/kg body weight/day for pregnant rats and their fetuses. The equivalent NOAEL for Magnesium Carbonate was determined to be > 331 mg/kg body weight/day.

General safety info about Sodium Carbonate from CIR

The Cosmetic Ingredient Review (CIR) Expert Panel assessed the safety of 6 carbonate salts which function as absorbents, bulking agents, opacifying agents, pH adjusters, buffering agents, abrasives, and oral care agents in cosmetic products. The Panel reviewed relevant data relating to the safety of these ingredients, and concluded that these carbonate salts are safe in the present practices of use and concentration in cosmetics when formulated to be non-irritating.
