Sodium Caproyl Lactylate is a sodium salt of an alkanoyl lactylate and is used as a cosmetic emulsifying surfactant. It combines a fatty-acid-derived lipophilic portion with lactylate functionality, providing surface-active properties that can support the formation and stabilization of suitable oil-in-water formulations.
Sodium Caproyl Lactylate is primarily used for its emulsifying properties in cosmetic and personal-care formulations. It can help bring oil and water phases together, improve interfacial compatibility and contribute to formulation uniformity.
The ingredient can be evaluated in skin-care products, creams, lotions, cleansing formulations, hair-care products, shampoos, conditioners and other personal-care systems, depending on the selected grade and formulation requirements.
The INCI ingredient is recognized as an emulsifying surfactant in cosmetic applications.
Sodium Caproyl Lactylate is an alkanoyl lactylate salt associated with a C10 fatty-acid component under INCI naming conventions. The CIR safety assessment identifies it as the sodium salt of the capryl ester of lactyl lactate and notes that, under INCI conventions, a C10 ester is designated Caproyl.
Its structure contains both lipophilic and polar portions, allowing it to function at the interface between oil and water.
Key characteristics include:
Sodium Caproyl Lactylate is chemically described as a sodium salt of an alkanoyl lactylate. Some databases identify the material as decanoic acid, 2-(1-carboxyethoxy)-1-methyl-2-oxoethyl ester, sodium salt.
PubChem records a compound under the name Sodium Caproyl Lactylate with molecular formula C₁₂H₁₉NaO₆ and molecular weight 282.26 g/mol. However, because commercial and regulatory records show identifier differences, the exact product documentation should be used when assigning regulatory identifiers to a specific grade.

Important procurement parameters include:
Sodium Caproyl Lactylate is an alkanoyl lactylate salt used primarily as an emulsifying surfactant in cosmetic formulations.
The INCI name is Sodium Caproyl Lactylate.
Current databases report different CAS identifiers for Sodium Caproyl Lactylate. SpecialChem and COSMILE-related records list 29051-57-8, while the 2024 CIR safety assessment lists 13557-74-9. The CAS number for the actual commercial grade should therefore be taken from the manufacturer's current SDS/COA.
PubChem lists C₁₂H₁₉NaO₆ for its discrete Sodium Caproyl Lactylate compound record.
The PubChem compound record gives a molecular weight of approximately 282.26 g/mol.
Its principal cosmetic function is emulsification. It is used to support the formation and stabilization of suitable oil-water formulations.
Yes. It can be evaluated in suitable creams, lotions and other emulsion-based formulations.
Yes. Commercial formulation examples include hair-care applications such as conditioners and shampoos.
The Cosmetic Ingredient Review's 2024 safety assessment concluded that the reviewed alkanoyl lactylate salts, including Sodium Caproyl Lactylate, are safe in cosmetics under the stated practices of use and concentration when formulated to be non-irritating and non-sensitizing.
