Magnesium Carbonate

The Basics On Magnesium Carbonate

What is Magnesium Carbonate?

Inorganic mineral salt used as an absorbent, opacifying agent, coloring agent, or to adjust the pH of products.

What are other names for Magnesium Carbonate?

CARBONIC ACID, MAGNESIUM SALT (1:1), HEAVY MAGNESIUM CARBONATE, LIGHT MAGNESIUM CARBONATE, and MAGNESIUM CARBONATE

What is Magnesium Carbonate used for?

And magnesium carbonate is a mineral salt and best used for its absorbent qualities and talent for balancing the pH in your skin. In fact, Rouleau includes it in her Night Time Spot Lotion to dry out pustular blemishes.

Magnesium Carbonate During Pregnancy

What we know about using Magnesium Carbonate while pregnant or breastfeeding

Limited information available.

Oral Calcium Carbonate Female Swiss mice were bred after feeding (number of animals/feeding duration not stated) them a diet supplemented with 0.5%, 1%, or 2% Calcium Carbonate. 22 First and second litters were studied. Calcium Carbonate (1% and 2% in diet) yielded an intake of approximately 3 g/kg body weight. When compared to the control diet, the supplemented diet significantly decreased the number and total weight of the weanling mice, and increased the proportion of deaths. Calcium Carbonate (2%) in the diet also caused hypertrophy of the heart and a tendency toward decreased thymus weight in weanling mice. Potassium Carbonate The teratogenicity of Potassium Carbonate was evaluated using groups of 22 to 25 CD-1 mice, according to a protocol similar to OECD Test Guideline 414.23,29 The test substance was administered, by gavage, at dose rates of 0, 2.9, 13.5, 62.5, or 290 mg/kg body weight/day, on gestation days 6 through 15. On day 17, Caesarean section was performed on Distributed for comment only — do not cite or quote all of the dams, and the following information was recorded: sex, numbers of corpora lutea, implantation sites, resorption sites, live and dead fetuses, and body weights of live pups. The urogenital tract of each dam was examined in detail for anatomical normality. All of the fetuses were examined grossly for the presence of external congenital abnormalities. Onethird of the fetuses in each litter were subjected to detailed visceral examinations, and the remaining two-thirds were examined for skeletal defects. There were no effects on mortality, body weight gain, or the urogenital tracts of dams. The no-observed-effect-level (NOEL) for maternal toxicity was 290 mg/kg body weight/day (i.e., the highest dose tested). There were no effects on any of the following: numbers of corpora lutea, live litters, implantations, resorptions, live and dead fetuses, the sex ratio of the fetuses, or the average fetal weight. The incidence of soft tissue and skeletal abnormalities within groups treated with Potassium Carbonate did not differ from that of sham-treated controls. The NOEL for developmental toxicity/teratogenicity was 290 mg/kg body weight/day. The teratogenicity of Potassium Carbonate was also evaluated using groups of 22 to 25 albino rats (Wistar-derived stock).29 The test substance was administered (by oral intubation), on gestation days 6 through 15, at dose rates of 0, 1.8, 8.4, 38.8, or 180 mg/kg body weight/day according to the procedure in the preceding experiment, except that Caesarean section was performed on day 20. There were no discernible effects on nidation or on maternal or fetal survival. Furthermore, the number of abnormalities observed in either soft or skeletal tissues of the test groups did not differ from the number occurring spontaneously in the sham-treated controls. Inhalation Potassium Carbonate The developmental toxicity potential of a Potassium Carbonate scrubbing solution, used extensively in petroleum refineries to remove CO2 from hydrogen gas streams, was evaluated.30 Pregnant female CD (Sprague-Dawley) rats (number not stated) were exposed to aerosols of a ‚Äúused‚Äù scrubbing solution at 0.05, 0.1, 0.2, or 0.3 mg/l for 6 h/day on days 6-19 of pregnancy. Control animals were exposed to filtered air under the same exposure conditions. Dams were killed on day 20 of pregnancy and a laparohysterectomy was performed. The mass median aerodynamic diameter of aerosol particles ranged from 1.6 to 2.8 ¬µ, with geometric standard deviations between 2.0 and 2.3 ¬µ. The overall pregnancy rate was high (> 95%) and equivalent across all groups. All pregnant dams had live litters, and 22-24 litters were examined in each group. Treatment-related clinical signs consisted of rales, observed at all exposure levels, and gasping only at the 0.3 mg/l exposure level. The occurrence of rales was presumably a localized effect on the respiratory tract, and was likely due to the irritating properties of the scrubbing solution. Maternal toxicity was exhibited in the 0.3 mg/l group, including reduced body weight, weight gain, and food consumption, and one possible treatment-related death on gestation day 17. At the scheduled necropsy, there were no treatment-related, gross pathological observations and no statistically significant differences in measurements of reproductive and developmental parameters. The incidences of fetuses with skeletal variations involving the sternum were clustered in two litters at the highest exposure level, with atypically low-term fetal body weights. Under the conditions of this investigation, Potassium Carbonate scrubbing solution was not a developmental toxicant.

General safety info about Magnesium Carbonate from CIR

According to the International Cosmetic Ingredient Dictionary and Handbook, the functions of these ingredients in cosmetic products include: absorbents, bulking agents, opacifying agents, pH adjusters, buffering agents, abrasives, and oral care agents (Table 1).1 The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated the safety of Sodium Sesquicarbonate, Sodium Bicarbonate, and Sodium Carbonate in cosmetic products, and concluded that these ingredients are safe as presently used in cosmetics.2 A CIR final report with this conclusion was published in 1987. Subsequently, during a Panel re-review of the safety of these ingredients in 2004, the conclusion originally determined by the Panel was reaffirmed. 3 Routinely, if 15 or more years have passed since a final safety assessment was issued by the Panel, the safety of ingredients reviewed in that safety assessment is re-reviewed, taking into consideration new data that have become available in the published literature.
