What is Isopropyl Palmitate CAS 142-91-6?

Isopropyl palmitate, commonly called IPP, is the ester of isopropyl alcohol and palmitic acid. It is a clear, low-odor oily liquid used mainly as an emollient, spreading agent and solvent in cosmetics, personal-care and topical pharmaceutical products.

How does isopropyl palmitate differ from isopropyl myristate?

Isopropyl palmitate is based on C16 palmitic acid, while isopropyl myristate is based on C14 myristic acid. IPP therefore has a slightly higher molecular weight and typically gives a somewhat richer skin feel and different spreading profile.

What are the main applications?

It is used in creams, lotions, make-up, bath oils, hair-care products, sun-care products, antiperspirants, fragrance vehicles and topical pharmaceutical formulations where a light emollient or solubilizer is required.

Can it be used in anhydrous systems?

Yes. IPP works well as a solvent, carrier or solubilizer in anhydrous oil-based systems such as bath oils, body oils, antiperspirant sticks and fragrance preparations.

Which grade and packaging does this listing cover?

The listing is cosmetic/pharmaceutical grade and is supplied in 180-200 kg steel drums or IBC tanks. Bulk packing can be customized on request.

What specifications should be confirmed before ordering?

Confirm appearance, color, odor, acid value, saponification value, iodine value, moisture, purity and microbial limits if required. Request the current batch analysis, technical data and safety information before purchase.

How should isopropyl palmitate be stored and handled?

Store in tightly closed, light-protected containers in a cool, dry, ventilated area away from heat, ignition sources and strong oxidizers. Use suitable gloves and eye protection, and follow the safety information for spill and disposal procedures.

Isopropyl Palmitate CAS 142-91-6

Isopropyl Palmitate (CAS 142-91-6), chemically identified as the ester of isopropyl alcohol and palmitic acid, is a non-greasy emollient and thickening agent functioning as a primary texture modifier in cosmetic skin care formulation and topical pharmaceutical preparations. This clear, colorless liquid, widely technically referred to as IPP or isopropyl hexadecanoate, possesses excellent spreadability and penetrating properties, serving to reduce the oily feel of creams while acting as a binder in pressed powders and a lubricating agent in hair care systems. We provide bulk supply of this cosmetic grade ingredient with competitive factory pricing to streamline procurement for personal care manufacturers. Our production capabilities ensure low acid values and odor neutrality, making MSDS, TDS, COA available alongside customized specifications to meet strict regulatory compliance standards.

Storage Conditions

Store in a cool, dry and well-ventilated warehouse.
Recommended storage temperature: 10 – 30 °C.
Keep container tightly closed to avoid moisture and contamination.
Protect from direct sunlight, heat sources and strong oxidizing agents.

Safety Precautions

Isopropyl Palmitate is considered to have low acute toxicity and is widely used in cosmetic and topical applications.
Avoid direct contact with eyes and prolonged contact with skin in concentrated form.
Use appropriate personal protective equipment (PPE) during handling: gloves, goggles and protective clothing as needed.
Ensure good ventilation in the working area to minimize exposure to mist or vapors.
In case of eye contact: rinse immediately with plenty of water and seek medical advice if irritation persists.
In case of skin contact: wash with soap and water; remove contaminated clothing.
For spills: contain and absorb with inert material, then dispose according to local regulations.
Combustible liquid—keep away from open flames and high temperatures.
