Purity: ≥98%
Chlorphenesin (NSC-6401) is a synthetic preservative and cosmetic biocide that helps prevent the growth of microorganisms. It is used in skin care as a cosmetic biocide, and acts as a centrally acting muscle relaxant. Also acts as a reversible antigen-associated immunosuppressant, and an antibacterial and antifungal agent used in numerous eye care cosmetics.
| ln Vitro |
Human meibomian gland epithelial cells (HMGECs) exposed to chlorphenesin (0.01, 0.1, 0.3%; 30-min exposure) exhibit a dose-dependent significant reduction in Akt pathway activity[2].
The effects of chlorphenesin (0.1, 0.3%; 24 hours) include rounding, atrophy, poor adherence, detachment, and a marked decrease in the number of immortalized HMGECs (IHMGECs)[2].

| Additional Infomation |
Chlorphenesin is glycerol in which the hydrogen of one of the primary hydroxy groups is substituted by a 4-chlorophenyl group. It has antifungal and antibacterial properties, and is used for treatment of cutaneous and vaginal infections. Its 1-carbamate is used as a skeletal muscle relaxant for the treatment of painful muscle spasm. It has a role as a muscle relaxant, an antibacterial drug and an antifungal drug. It is a glycol, a member of propane-1,2-diols and a member of monochlorobenzenes.
A centrally acting muscle relaxant. Its mode of action is unknown. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1203) See also: ... View More ... Drug Indication Used, along with rest and physical therapy, to treat injuries and other painful muscular conditions. Investigated for use in trigeminal neuralgia (tic douloureux), a neuropathic disorder characterized by severe facial pain. Was investigated as a modulator of histamine release. Mechanism of Action The mechanism of action of chlorphenesin is not well defined, and its effects are measured mainly by subjective responses. It is known that chlorphenesin acts in the central nervous system (CNS) rather than directly on skeletal muscle. Pharmacodynamics Chlorphenesin is a muscle relaxant. It blocks nerve impulses (or pain sensations) that are sent to the brain. |

| Solubility (In Vitro) |
DMSO : 41~100 mg/mL ( 202.33~493.51 mM )

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (12.34 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 (12.34 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in 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 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
