Chemistry & Functionality
Rapid Phase Transition & Thermal Dynamics
Mechanism:
- Kester Wax K-24’s low melting point (25°C) is a direct result of its specific molecular structure. The short alkyl chains and ester linkage contribute to weak intermolecular forces, facilitating a rapid transition from a crystalline solid to a liquid state upon minimal heat input (skin contact).
- This rapid phase change involves the absorption of latent heat, which can manifest as a subtle cooling sensation. This is a transient endothermic process.
Formula Effect:
- This property is crucial for delivering an immediate “slip” effect in formulations. The instant liquefaction provides a smooth, gliding sensation upon application.
- The cooling effect, while subtle, can enhance the sensory profile of products, particularly in warm climates or for products designed for soothing applications.
- This rapid phase transition allows for the product to be easily workable during manufacturing.
Emolliency & Sensory Modulation
Mechanism:
- As an emollient, Kester Wax K-24 forms a thin, nonocclusive film on the skin’s surface. This film lubricates the stratum corneum, reducing transepidermal water loss (TEWL) and enhancing skin hydration.
- The “dry, powdery” feel arises from the specific arrangement of the monoester molecules on the skin. This arrangement minimizes the perception of oiliness while maintaining lubricity.
Formula Effect:
- This characteristic allows formulators to create products with a luxurious, non-greasy texture, appealing to consumers who prefer lightweight formulations.
- It enables the creation of balanced formulations where the emollient properties of oils and esters are harnessed without the associated heavy or greasy feel.
- The film that is created is able to help with the even distribution of pigments, and other powder based […]
