Effects During Pregnancy and Lactation
◉ Summary of Use during Lactation
Very little cyclamate enters breastmilk after maternal ingestion. However, some authors suggest that women may wish to limit the consumption of nonnutritive sweeteners while breastfeeding because their effect on the nursing infants are unknown.

Cyclohexylsulfamic acid is a member of the class of sulfamic acids that is sulfamic acid carrying an N-cyclohexyl substituent. It has a role as a human xenobiotic metabolite and an environmental contaminant. It is functionally related to a sulfamic acid. It is a conjugate acid of a cyclohexylsulfamate.
Cyclamic acid has been reported in Euglena gracilis with data available.
Salts and esters of cyclamic acid.

H2O : ≥ 100 mg/mL (~557.91 mM)
DMSO : ~100 mg/mL (~557.91 mM)

Solubility in Formulation 1: ≥ 2.5 mg/mL (13.95 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.5 mg/mL (13.95 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.
