Diisopropyl Adipate丨CAS 6938-94-9

Diisopropyl adipate丨CAS 6938-94-9 is a clear, colorless ester derived from adipic acid and isopropyl alcohol. It is known for its excellent emollient and solvent properties, making it widely used in cosmetics, personal care products, and pharmaceuticals. Additionally, its chemical stability and compatibility with various active ingredients make it a valuable component in specialty formulations.

1. Cosmetic and Personal Care Products
● Primary use is as an emollient in products like:
o Skin creams
o Lotions
o Sunscreens
o Hair conditioners
● Provides a non-greasy, silky-smooth feel on the skin.
● Enhances spreadability, contributing to better absorption and even application.
2. Pharmaceutical Formulations
● Used as a carrier or solvent for topical drug delivery systems such as:
o Transdermal patches
o Creams and gels
● Improves skin penetration of active pharmaceutical ingredients (APIs), especially in dermal therapies.
● Helps stabilize formulations by preventing crystallization of active ingredients.
3. Sunscreen and UV Filter Systems
● Often incorporated in sunscreen formulations to improve dispersion of UV filters (like titanium dioxide or avobenzone).
● Acts as a plasticizer and solvent, enabling homogeneous mixtures and enhancing product aesthetics.
4. Plasticizer in Polymers
● Functions as a low-volatility plasticizer in flexible PVC and other polymer systems.
● Provides flexibility without significantly affecting tensile strength or clarity.
● Suitable for medical-grade and specialty plastic products where low toxicity and mildness are desired.
5. Industrial Solvent
● Serves as a solvent or diluent in various chemical processes.
● Used in agrochemical formulations, ink, and coating industries for improved spreadability and substrate compatibility.

1. Excellent Skin Feel and Sensory Properties
● Leaves a light, velvety touch with no oily residue.
● Enhances consumer appeal of cosmetics by improving the texture and usability of formulations.
2. Safe and Mild
● Low skin irritation potential; suitable for sensitive skin.
● Often used in baby care and hypoallergenic formulations.
3. Good Solvency and Compatibility
● Efficient solvent for lipophilic substances, including fragrances, vitamins (e.g., Vitamin E), and UV filters.
● Compatible with a wide range of emulsifiers and other esters.
4. Stable and Non-Volatile
● Offers good oxidative and hydrolytic stability.
● Low volatility ensures it remains on the skin or within the formulation for extended periods.

Diisopropyl adipate丨CAS 6938-94-9 is a high-performance emollient and solvent used across personal care, pharmaceutical, and industrial sectors. Its combination of mildness, sensory appeal, and solvency makes it ideal for modern formulations where both function and feel are critical.
