What is Sodium Cocoyl Alaninate and Its Applications

Sodium cocoyl alaninate is a versatile and widely used ingredient in personal care products. It's a natural and biodegradable surfactant derived from coconut oil and alanine.

This gentle yet effective ingredient has a pH level of around 5.5, making it suitable for use in a variety of products, including shampoos, conditioners, and body washes. It's also known for its ability to create a rich lather and emulsify oils.

Sodium cocoyl alaninate is often used in combination with other natural ingredients to enhance its cleansing and moisturizing properties. For example, it can be paired with glycerin to create a hydrating and non-stripping cleanser.

In addition to its use in personal care products, sodium cocoyl alaninate is also used in industrial applications, such as in the production of detergents and cleaning solutions.

Sodium cocoyl alaninate is a sodium salt, which means it contains sodium as its primary component.

It's derived from coconut oil, specifically from the fatty acids found in it, thanks to an acylation reaction.

The "alaninate" part of its name refers to its connection to alpha- or beta-alanine, also known as aminopropanoic acid.

This ingredient is a result of combining these two components, making it a unique and complex substance.

Sodium cocoyl alaninate, sodium dodecyl sulfate, and emulsifier OP-10 are anionic surfactants used as foaming agents in this study, all with a purity of 90%.

These chemicals were supplied by Shandong Youso, Co., LTD, China.

Nitrogen with a purity of 99.99% was used as the gas phase in the foam system.

The purity of these chemicals is quite high, which suggests a focus on accuracy and precision in this study.

Sodium salts are commonly referred to as "sodium..." in ingredient names.

The name component "cocoyl" indicates that an ingredient contains fatty acids from coconut oil, specifically from the oil of the coconut tree (cocos nucifera).

Aminopropanoic acid is another term for alpha- or beta-alanine, a common building block of certain ingredients.

Sodium cocoyl alaninate is a versatile ingredient in cosmetics, serving as a pH adjuster to balance the pH of formulations.

It's often used in combination with other ingredients to create a stable and effective product.

Sodium cocoyl alaninate is also a surfactant, meaning it helps to reduce the surface tension of water, allowing it to penetrate the skin more easily.

This property makes it particularly useful in cleansing products, where it helps to remove dirt and impurities from the skin.

Sodium cocoyl alaninate is generally considered safe and gentle on the skin, making it a popular choice for use in facial cleansers and other personal care products.

Its mild nature also makes it suitable for use in products for sensitive skin, providing a gentle and non-irritating cleansing experience.

Sodium cocoyl alaninate, or SCA for short, is a versatile surfactant that can be used in various applications. It has a better foaming ability than SDS, a similar surfactant.

The foaming volume of SCA is significantly higher than that of SDS, especially when the concentrations exceed 0.10 wt%. In fact, the volume foamed by 0.20 wt% SCA is almost twice that of the 0.20 wt% SDS.

Surfactants like SCA, SDS, and OP-10 are often compared to determine their foaming performances. Their foaming volumes all increase with the increase in surfactant concentration.

SCA requires a smaller usage to achieve a better foaming ability compared to OP-10. The optimum concentration of SCA is 0.20 wt%, while OP-10 requires a higher concentration of 0.50 wt% to achieve a similar foaming ability.

Sodium cocoyl alaninate (SCA) has a critical micelle concentration (CMC) of 7.94 mM, which is relatively close to that of sodium dodecyl sulfate (SDS) with a CMC of 7.41 mM.

The similarity in CMC values between SCA and SDS can be attributed to their molecular structure, where SCA's cocoyl group has a mixture of acyl groups with different chain lengths, including lauroyl, which is a straight-chain hydrophobic group.

The CMC determination by surface tension and conductivity methods show that SCA has a CMC of 9.5 mM, which is slightly higher than the value obtained from surface tension data.

SCA proves to be slightly more surface active than SDS due to its mixed alkyl chain length.

The interfacial properties of SCA were analyzed using a spinning drop tensiometer, which showed that the equilibrium interfacial tension (IFT) values decrease significantly with an increase in surfactant concentration.

The minimum IFT value attained by SCA is 0.069 mN/m, which is not ultra-low but can still yield stable emulsions.

SCA exhibits superior interfacial activity compared to SDS, primarily due to the mixture of hydrophobic chain lengths in its cocoyl group.

The CMC variation between SCA and SDS agrees with the surface tension method, with values being a bit higher due to the difference in the method of determination.

Sodium cocoyl alaninate (SCA) has been extensively studied in various experiments to understand its wettability alteration potential.

The spreading coefficient, a measure of fluid's ability to wet a surface, is a key factor in determining SCA's effectiveness.

Contact angle measurements have been used to indirectly determine the spreading coefficient, which is a function of the interfacial free energies of the various phases.

The contact angle for water on a quartz surface used for SCA was around 89° initially, and 66° after 10 minutes.

This observation shows that the quartz surfaces were intermediate wet, indicating a moderate level of wettability.

Both SCA and SDS, an anionic surfactant, exhibited excellent wetting power in altering quartz surface wettability.

However, SCA showed better wettability alteration potential over SDS, despite both surfactants using the ion-pair mechanism to alter the quartz surface.

SCA proved to be better than SDS in reducing surface and interfacial tension, which are related to the contact angle and hence the observed superiority in wettability alteration.

The contact angle variation with concentration for SCA and SDS at 25°C was also studied, providing valuable insights into the optimal concentration for SCA.
