Product Description
CAS 334-48-5 Capric Acid/ Decanoic Acid or C10 Fatty Acid
Capric Acid / Decanoic Acid (CAS 334-48-5) - High Purity Medium-Chain Fatty Acid
Capric Acid (also known as Decanoic Acid, n-Decanoic Acid, or C10 Fatty Acid) is a saturated medium-chain fatty acid (MCFA) with the molecular formula C₁₀H₂₀O₂. It occurs naturally in coconut oil, palm kernel oil, and goat's milk. Capric acid appears as a white crystalline solid with a characteristic rancid-like odor. It is widely valued in the chemical, medical, food, and personal care industries for its excellent emulsifying, antibacterial, and lubricating properties.

Product Functions
- Antibacterial & antifungal - Effective against bacteria, yeast, and molds; used as a natural preservative.
- Emulsification & stabilization - Improves texture and stability in creams, lotions, and food emulsions.
- Lubrication - Provides slip and anti-stick properties in industrial and cosmetic formulations.
- Intermediate for synthesis - Key building block for esters, polyols, surfactants, and lubricants.
- pH regulator - Mildly acidic, adjusts pH in personal care and medical preparations.
- Penetration enhancer - Facilitates dermal absorption in transdermal medical delivery systems.
Application Areas
1. Food & Beverage Industry
- Flavoring agent (butter, cheese, milk notes)
- Antibacterial food preservative (bakery, dairy, meat products)
- Production of medium-chain triglycerides (MCTs) and emulsifiers (e.g., glycerol monocaprate)
2. Personal Care & Cosmetics
- Creams, lotions, soaps, and shampoos (as emulsifier, thickener, and foam booster)
- Deodorants and antiperspirants (bacteriostatic action)
- Hair conditioners and shaving creams (lubricity)
3. Medicals
- Excipient in suppositories and ointments
- Component in antifungal and antibacterial preparations
- Capric acid salts (sodium caprate) used as intestinal permeation enhancers
4. Industrial & Chemical Manufacturing
- Production of plasticizers, stabilizers, and synthetic lubricants
- Raw material for capric acid esters (esters for solvents, coatings, and fragrances)
- Rubber processing aid and defoamer
5. Agriculture & Animal Feed
- Feed additive for gut health and growth promotion in livestock
- Bactericide in crop protection formulations
Manufacturing Process
Capric acid is primarily derived from natural fats and oils via hydrolysis and fractionation:
- Feedstock preparation - Coconut oil or palm kernel oil is refined, bleached, and deodorized (RBD).
- Fat splitting (hydrolysis) - Oil is hydrolyzed with high-pressure steam (250-300 °C) to release mixed fatty acids and glycerol.
- Fractional distillation - The mixed fatty acids (C6-C18) are separated by vacuum distillation based on carbon chain length. Capric acid (C10) is collected at specific temperature/pressure cuts.
- Hydrogenation (optional) - If required, residual unsaturated fatty acids are hydrogenated to achieve high saturation (>99%).
- Purification - Further refining via crystallization, bleaching, or deodorization to meet food/medical grade specifications.
- Flaking/packaging - Molten capric acid is solidified into flakes or crystals and packaged under inert gas.
Synthetic capric acid (from petrochemical sources) is also available but less common due to natural product preference.

Frequently Asked Questions
Q1: Is capric acid the same as decanoic acid?
A: Yes. Capric acid and decanoic acid are identical - both refer to the C10 saturated fatty acid. "Decanoic" is the IUPAC name; "capric" is derived from Latin caper (goat), as it is found in goat's milk.
Q2: What is the difference between capric acid and caprylic acid?
A: Caprylic acid (C8, CAS 124-07-2) has 8 carbon atoms, while capric acid (C10) has 10. Capric has a slightly higher melting point (31.5 °C vs 16.5 °C) and stronger antibacterial activity against certain pathogens.
Q3: Is capric acid safe for skin and food?
A: Yes. Capric acid is generally recognized as safe (GRAS) by the FDA for food additives (21 CFR 172.860) and is widely used in cosmetics (CIR approved). However, high concentrations may cause mild skin irritation; always follow recommended usage levels (typically 1-10%).
Q4: How should capric acid be stored?
A: Store in a cool, dry, well-ventilated area away from strong oxidizers and direct sunlight. Keep containers tightly closed. Shelf life is 24 months when stored below 25 °C.
Q5: Do you provide samples?
A: Yes, free samples (50-200 g) are available for qualified customers. Shipping costs apply for international courier.
Q6: Can you supply customized specifications (e.g., lower water content, specific melting range)?
A: Yes, we offer custom refining, blending, and micronization. Please contact our technical sales team with your requirements.
Q7: What documentation do you provide?
A: Each shipment includes Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), Technical Data Sheet (TDS), and Origin Certificate. Additional documents (BSE/TSE, GMO-free, Allergen, Halal, Kosher) are available upon request.
