Calcium Caprylate is the calcium salt of caprylic acid, also known chemically as calcium octanoate. It is a specialty fatty-acid salt identified by CAS Number 6107-56-8, with the anhydrous molecular formula C₁₆H₃₀CaO₄ and molecular weight of approximately 326.49 g/mol. Calcium Caprylate is also available commercially as a monohydrate, for which the molecular weight is approximately 344.51 g/mol.
The ingredient belongs to the family of medium-chain fatty-acid salts. Its combination of calcium and caprylate groups gives it distinctive physical and surface-active characteristics. Commercial material is generally supplied as a white to off-white powder.
In cosmetic raw-material applications, Calcium Caprylate is primarily relevant to emulsifying, stabilizing and specialty surfactant systems. Its precise functionality depends on the formulation, concentration, particle characteristics and hydration state of the supplied material.
Calcium Caprylate is formed from two molecules of caprylic acid associated with one calcium ion. Its anhydrous chemical formula is Ca(C₈H₁₅O₂)₂, corresponding to C₁₆H₃₀CaO₄.
The standard CAS identity 6107-56-8 is associated with Calcium Caprylate/Calcium Octanoate. Commercial references also identify this material as Caprylic Acid Calcium Salt and Octanoic Acid Calcium Salt.
An important technical consideration is the hydration state. Anhydrous Calcium Caprylate has a molecular weight of approximately 326.49 g/mol, while the monohydrate is approximately 344.51 g/mol. Therefore, the actual form supplied should be clearly identified in product documentation.
Commercial specifications may include assay, calcium content, free caprylic acid, moisture, particle characteristics and melting behavior. One commercial reference reports assay NLT 99%, calcium content approximately 17% on a dried basis, free caprylic acid NMT 0.1%, and moisture NMT 6%. These values are supplier-specific and should not be treated as universal cosmetic specifications.
Calcium Caprylate can function as a specialty emulsifying and stabilizing ingredient. As a fatty-acid salt, it can contribute surface-active properties to suitable formulation systems.
Its medium-chain fatty-acid structure provides a balance between the hydrophobic caprylate chain and the ionic calcium-containing portion. This can be relevant when developing formulations requiring fatty-acid-derived functional ingredients.
Calcium Caprylate should not automatically be described as a universal preservative. Although caprylate salts have antimicrobial-related properties in some technical contexts, the finished-product function and regulatory status must be established for the specific formulation and target market.
Calcium Caprylate may be considered for:
The material may also be encountered in technical, food-related and other specialty applications; however, the grade and regulatory suitability should always be evaluated according to the intended end use.
For cosmetic manufacturing, the supplied grade should be selected according to the desired physical properties, purity, hydration state and formulation requirements.
Calcium Caprylate has limited water solubility, so formulators should consider dispersion, particle size, phase compatibility and processing conditions when incorporating it into a formulation. A commercial reference reports water solubility of approximately 1.9 g/L at 20°C, although solubility can depend on material form and test conditions.
The hydration state is another important consideration. Anhydrous and monohydrate Calcium Caprylate have different molecular weights and moisture characteristics, which can affect formulation calculations.
Quality-control testing may include identification, assay, calcium content, free caprylic acid, moisture, residue, elemental impurities and physical characteristics. HPLC assay should not be claimed unless the actual supplied product is tested using a validated HPLC method.
Because no single universal cosmetic COA specification applies to every commercial Calcium Caprylate grade, the final numerical specifications should be based on the actual approved product specification and batch COA.
Calcium Caprylate is a specialty fatty-acid-based cosmetic ingredient for manufacturers developing emulsifying, stabilizing and specialty formulation systems. A Calcium Caprylate Cosmetic Ingredient Manufacturer in India can support bulk procurement of this specialized raw material for cosmetic and personal-care applications.
For B2B purchasing, manufacturers should evaluate the CAS identity, hydration state, assay, calcium content, free caprylic acid, moisture, appearance, particle characteristics and documentation. Clear identification of anhydrous versus monohydrate material is particularly important for formulation calculations.
As a specialized cosmetic raw material and personal care ingredient, Calcium Caprylate can be considered where controlled fatty-acid salt functionality is required.
