Applications

Cetyl palmitate finds applications in the following aspects due to its versatile properties:

Cosmetics and Personal Care

Emollient and Skin Conditioning Agent: Cetyl palmitate is extensively used as an emollient in cosmetic formulations. Its ability to form a protective barrier on the skin's surface helps to retain moisture, thereby enhancing skin hydration and smoothness.
Thickening Agent: Cetyl palmitate's waxy nature makes it an excellent thickening agent in various formulations. It increases the viscosity and stability of cosmetic products, ensuring they maintain the desired consistency and spreadability. This is particularly important in creating creams, lotions, and balms that require a stable and uniform texture. Additionally, in stick products like deodorants and lip balms, cetyl palmitate provides structural integrity, helping the products retain their shape and application properties.

Pharmaceutical Applications

In the pharmaceutical sector, cetyl palmitate serves as an excipient and hardening agent. Its inert nature and compatibility with active ingredients make it suitable for use in ointments, creams, and suppositories. For example, it is often employed in topical formulations to improve the consistency and stability of the product, ensuring efficient delivery of active pharmaceutical ingredients.

Packaging and Storage

Packaging Options: Typically packaged in 25kg barrels, customizable according to customer requirements.
Storage Conditions: Stored in a cool, dry place away from direct sunlight and heat sources to maintain the compound's integrity and efficacy.
Shelf Life: 2 years
