    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.

    Applications

    1. Skin Care Products

    • Creams, lotions, serums, body milks, hand creams
    • Acts as a light emollient, giving a smooth, non-sticky skin feel
    • Reduces greasiness of high-viscosity oils and butters
    • Helps disperse oil-soluble actives, filters and pigments

    2. Sun Care & Color Cosmetics

    • Sunscreens, BB/CC creams, foundations, lipsticks, makeup removers
    • Improves spreadability and uniform film formation on the skin
    • Enhances gloss in color cosmetics and helps pigment wetting

    3. Hair Care Products

    • Conditioners, hair masks, hair oils, styling products
    • Provides conditioning effect and smooth feel without heavy build-up
    • Helps improve combability and shine

    4. Pharmaceutical & Topical Preparations

    • Ointments, gels, medicated creams, massage formulations
    • Used as a solvent and carrier for active ingredients
    • Provides pleasant sensory profile for topical dosage forms

    5. Other Industrial Uses

    • Lubricant component in personal-care related applications
    • Plasticizer and processing aid in specific specialty formulations

    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.
    • Under proper storage conditions, the typical shelf life is 12–24 months in original unopened packaging.

    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.

    FAQ - Technical & Supply Chain

    • Q:

      What chemical characteristic distinguishes Isopropyl Palmitate (CAS 142-91-6) from Isopropyl Myristate (IPM)?

      A: Isopropyl Palmitate is derived from Palmitic Acid (C16) giving it a slightly higher molecular weight and viscosity compared to Isopropyl Myristate which is derived from Myristic Acid (C14); consequently, IPP provides a somewhat richer texture and higher occlusivity than the lighter, drier-feeling IPM.
    • Q:

      Is this ester ingredient intended for use as a solubilizer in anhydrous systems?

      A: Yes, IPP is frequently intended for use as a solvent and solubilizer in anhydrous formulations, such as bath oils and antiperspirants, where it effectively dissolves active ingredients without introducing water or instability to the matrix.
