Usage

Uses

Used in Cosmetic Industry:
Oleyl stearate is used as an emollient and skin-conditioning agent for its ability to soften and smooth the skin, providing a protective barrier to lock in moisture. Its non-greasy, lightweight texture makes it suitable for a wide range of personal care products, including lotions, creams, and hair care products.
Used in Skincare Products:
Oleyl stearate is used as a moisturizing agent to improve the skin's hydration and suppleness. It helps to maintain the skin's natural moisture balance, preventing dryness and promoting a healthy, radiant complexion.
Used in Hair Care Products:
In hair care products, oleyl stearate is used as a conditioning agent to improve the manageability and softness of hair. It helps to reduce frizz and static, leaving hair smooth and manageable.
Used in Formulation Stability:
Oleyl stearate functions as a solvent for other ingredients in cosmetic formulations, enhancing the overall consistency and stability of the products. This contributes to the performance and aesthetic appeal of skincare and hair care products, ensuring a pleasant user experience.

Enzymatic esterification of fatty acid esters by tetraethylammonium amino acid ionic liquids-coated Candida rugosa lipase

Enzymatic production of fatty acid esters from the esterification of oleyl alcohol with various fatty acids was investigated by using two new tetraethylammonium amino acid ionic liquids-coated Candida rugosa lipase (ILs-CRL) as biocatalysts in hexane. Both enzyme derivatives were prepared by mixing Candida rugosa lipase with tetraethylammonium l-histidinate (IL1) and tetraethylammonium l-asparaginate (IL2). The ILs-CRL system containing the equivalent protein concentration as in CRL showed higher esterification activity especially on medium chain fatty acids (C12-C16) as compared to non-coated CRL. Hydrophilicity of ILs may play an important role in hydrogen bonding with enzyme surface and consequently stabilize the ILs-CRL.

Engkabang fat esters for cosmeceutical formulation

Engkabang fat esters were synthesized from engkabang fat using an enzyme as catalyst. The main composition of the fat esters were oleyl palmitate, oleyl stearate and oleyl oleate. The percentage yield was 93.67%. Ternary phase diagrams systems containing fat esters/surfactant/water were constructed. Several regions appeared in the ternary phase diagrams such as isotropic, homogenous, liquid crystal, two-phase and three-phase regions. Increasing the hydrophilic-lipophilic balance value of the used surfactants gave a larger homogenous and isotropic region in ternary phase diagrams of engkabang fat esters/nonionic surfactant/deionized water. Isotropic and homogenous regions in the ternary phase diagram of engkabang fat esters: PEG-40 hydrogenated castor oil (2:1)/polyoxyethylene(20) sorbitan tri-oleate/deionized water, was the largest when compared to the other ternary phase diagrams. The isotropic and homogenous region can be used as a medium in formulation of cosmetics and pharmaceutical products such as creams, lotions, balms and lipsticks. AOCS 2010.

Synthesis of Fatty Acid Ester by Corynebacterium sp. S-401

Resting cells and acetone-dried cells of Corynebacterium sp.S-401 catalyzed the fatty acid ester synthesis of various alcohols and fatty acids.These reactions were carried out in phosphate buffer and/or organic solvents.In some cases synthetic reactions of esters in nonpolar solvents, such as n-hexane and benzene, gave better results compared with those obtained in phosphate buffer.
