What is Deoxycholate Sodium?
Deoxycholate sodium (sodium deoxycholate) is the sodium salt of deoxycholic acid, a naturally occurring bile acid derived from cholesterol.
It is a water-soluble, anionic detergent with strong surfactant properties, widely used in pharmaceutical, cosmetic, and laboratory applications.
Chemical Profile:
- CAS Number: 302-95-4
- Molecular Formula: C₂₄H₃₉NaO₄
- Molecular Weight: 414.56 g/mol
- Solubility: Highly soluble in water (330 g/L at 15°C) and ethanol.
Key Characteristics:
- Detergent Action: Disrupts lipid membranes, solubilizes membrane proteins, and prevents nonspecific binding in affinity chromatography.
- Critical Micelle Concentration (CMC): 2–6 mM, enabling micelle formation for solubilization.
- pH Stability: Effective in neutral to alkaline conditions (pH 5–9).
Applications:
- Cosmetics: Emulsifier in creams, lotions, and serums.
- Pharmaceuticals: Cell lysis buffers, drug solubilizers, and vaccine stabilizers.
- Research: Protein extraction, nucleic acid isolation, and viral membrane disruption.
What is Deoxycholate Sodium Used For?
1. Cosmetic Formulations
- Emulsification: Stabilizes oil-in-water or water-in-oil emulsions in skincare products.
- Solubilization: Enhances bioavailability of hydrophobic actives (e.g., retinoids, peptides).
- Antimicrobial Activity: Disrupts microbial cell membranes, facilitating the development of preservative-free formulations.
2. Pharmaceutical Manufacturing
- Cell Lysis: Extracts membrane proteins for drug delivery systems.
- Injectable Formulations: Prevent aggregation of therapeutic proteins.
- Topical Treatments: Solubilizes cholesterol for gallstone dissolution
3. Laboratory Research
- Protein Purification: Removes contaminants in chromatography columns.
- Viral Inactivation: Disrupts viral envelopes (e.g., SARS-CoV-2) for safety testing
How Deoxycholate Sodium Works (Mechanism of Action)
1. Membrane Disruption
- Micelle Formation: Binds to lipid bilayers, creating pores that destabilize membranes.
- Protein Solubilization: Extracts hydrophobic regions of membrane proteins, making them water-soluble.
2. Surfactant Activity
- Micelle Size: Approximately 2000 Da, ideal for solubilizing small to medium-sized hydrophobic molecules.
- Critical Role in Emulsions: Reduces interfacial tension between oil and water phases.
3. Enzyme Activation
- Cholesterol Metabolism: Activates TGR5 receptors, stimulating brown adipose tissue thermogenesis.
Sodium Deoxycholate Regulatory Status and Compliance
1. Cosmetic Regulations
- EU: Compliant with EC No 1223/2009 (Annex V).
- US: FDA-approved as a cosmetic ingredient (21 CFR 700.17).
2. Pharmaceutical Standards
- USP/NF: Meets monograph specifications for purity.
- GMP Compliance: Required for injectable formulations.
3. Certifications
- ISO 9001: Quality management systems.
- REACH: Compliant with EU chemical regulations.
Sodium Deoxycholate vs. Deoxycholic Acid
| Parameter | Sodium Deoxycholate | Deoxycholic Acid |
|---|---|---|
| Chemical Form | Sodium salt | Free acid |
| Solubility | Water-soluble | Lipid-soluble |
| Primary Use | Cosmetic emulsifiers, APIs | FDA-approved injectables (e.g., Kybella®) |
| pH Stability | Stable in neutral/basic pH | Prefers acidic environments |
Why Choose Sodium Deoxycholate?
- Superior Solubility: Ideal for aqueous formulations.
- Regulatory Compliance: GRAS (Generally Recognized As Safe) for cosmetics.
Takeaway: Sodium deoxycholate is preferred for topical formulations, while deoxycholic acid is used in clinical fat-dissolving injections.
Deoxycholate Sodium Dosage and Administration
Cosmetic Use
- Recommended Range: 0.1–2% w/w in formulations.
- Compatibility Testing: Ensure stability with preservatives (e.g., parabens) and fragrances.
2. Pharmaceutical Use
- Injectables: ≤0.5% w/v to avoid cytotoxicity.
- Oral Dosage: 300–1500 mg/day for gallstone dissolution (under medical supervision).
3. In Vitro Applications
- Cell Lysis Buffers: 1–2% w/v in RIPA buffer for mammalian cells.
What Are the Side Effects of Deoxycholate Sodium?
1. Cosmetic Safety
- Skin Irritation: High concentrations (>5%) may cause redness or dryness of the skin.
- Allergic Reactions: Rare, but possible in sensitive individuals.
2. Pharmaceutical Risks
- Hepatotoxicity: Prolonged use in parenteral formulations may strain liver function.
- Drug Interactions: Disrupts absorption of fat-soluble vitamins (A, D, E, K).
3. Occupational Hazards
- Inhalation: Causes respiratory irritation (NIOSH recommends P301+P310 PPE)
Deoxycholate Sodium Precautions and Drug Interactions
1. Cosmetic Precautions
- Patch Testing: Mandatory for new formulations.
- pH Stability: Avoid acidic conditions (<5) to prevent precipitation.
2. Pharmaceutical Interactions

- Estrogen therapy increases cholesterol saturation, counteracting therapeutic effects.
3. Handling Guidelines
- Storage: A cool, dry place (2–8°C) is recommended to prevent oxidation.
- Disposal: Follow local regulations for chemical waste.
How Long Does Deoxycholate Sodium Take to Work?
1. Cosmetic Effects
