Overview
Hexadecyl Isostearate is a synthetic ester derived from isostearic acid and cetyl alcohol. It is widely used in the cosmetic and personal care industry due to its excellent emollient properties. The compound is valued for its ability to improve product texture, enhance spreadability, and provide a non-greasy finish. Its compatibility with a wide range of cosmetic ingredients makes it a versatile additive in formulations such as lotions, creams, and hair care products. As a non-ionic ester, Hexadecyl Isostearate is stable under a variety of conditions and does not react with most other cosmetic ingredients. Its mild nature and skin-friendly properties make it suitable for use in sensitive skin products. The compound is typically synthesized through esterification, ensuring high purity and consistency for industrial applications.
Physical and Chemical Properties
Hexadecyl Isostearate is a colorless to pale yellow liquid with a low viscosity and a smooth, non-greasy texture. It has a molecular weight of 508.91 g/mol and a density of approximately 0.85 g/cm³. The compound is insoluble in water but readily soluble in oils and organic solvents, making it ideal for oil-based formulations. Its chemical stability and resistance to oxidation contribute to its long shelf life when stored properly. The ester’s unique molecular structure allows it to form a protective barrier on the skin, locking in moisture without clogging pores. These properties make it a preferred ingredient in moisturizers, sunscreens, and other skincare products designed to improve skin hydration and elasticity.
Main Applications
Hexadecyl Isostearate is primarily used in the cosmetic and personal care industry as an emollient and skin-conditioning agent. It is commonly found in moisturizers, lotions, creams, and sunscreens, where it enhances product spreadability and provides a silky feel. The compound is also used in hair care products, such as conditioners and styling creams, to improve manageability and reduce frizz. In addition to its cosmetic applications, Hexadecyl Isostearate is sometimes used in pharmaceutical formulations as a carrier for active ingredients. Its ability to dissolve lipophilic compounds makes it useful in topical drug delivery systems. The ester’s mildness and compatibility with sensitive skin further expand its applications in baby care products and dermatological treatments.
Safety and Storage
Hexadecyl Isostearate is generally recognized as safe for topical use in cosmetics and personal care products. However, it is important to follow standard safety precautions, such as avoiding ingestion and eye contact. The compound is non-irritating and non-sensitizing for most users, but patch testing is recommended for individuals with sensitive skin. Proper storage is essential to maintain the quality of Hexadecyl Isostearate. It should be kept in a cool, dry place away from direct sunlight and extreme temperatures. Containers should be tightly sealed to prevent contamination and oxidation. Bulk storage in stainless steel or high-density polyethylene containers is recommended for industrial use.
B2B Procurement Guide
When procuring Hexadecyl Isostearate, B2B buyers should verify the CAS number (102769-58-8) to ensure product authenticity. Requesting a Certificate of Analysis (COA) and Safety Data Sheet (SDS) from suppliers is essential to confirm purity and compliance with regulatory standards. The compound is typically available in drums or totes, with prices ranging from approximately $20 to $50 per kg, depending on quantity and supplier. Buyers should also consider the supplier’s reputation, production capacity, and ability to provide consistent quality. Establishing long-term relationships with reliable suppliers can ensure a steady supply of high-quality Hexadecyl Isostearate for cosmetic and pharmaceutical formulations. Additionally, buyers should stay informed about regulatory updates and industry trends to make informed procurement decisions.
