    Product Description

    Isopropyl Palmitate, CAS 142-91-6, also known as IPP or isopropyl hexadecanoate, is the ester of isopropyl alcohol and palmitic acid; the EC/EINECS number is 205-571-1.

    Synonyms: IPP; isopropyl hexadecanoate; hexadecanoic acid isopropyl ester; palmitic acid isopropyl ester; 1-methylethyl hexadecanoate.

    CAS: 142-91-6.

    Molecular formula: C₁₉H₃₈O₂.

    Molecular weight: 298.50 g/mol.

    EC number: 205-571-1.

    It is a clear, colorless to pale-yellow liquid, insoluble in water and soluble in oils and organic solvents.

    The assay (GC) is ≥98.0%; acid value ≤0.5 mg KOH/g and hydroxyl value ≤5.0 mg KOH/g.

    Saponification value is 175–190 mg KOH/g; density at 20 °C is 0.850–0.860 g/cm³.

    It is used in creams, lotions, make-up, bath oils and hair-care products as a light emollient.

    It is used in sun-care products, antiperspirants, fragrance vehicles and topical pharmaceutical formulations.

    It works well as a solvent, carrier or solubilizer in anhydrous oil-based systems.

    Compared with isopropyl myristate, IPP is based on C16 palmitic acid and gives a somewhat richer skin feel.

    Confirm appearance, color, odor, acid value, saponification value, iodine value, moisture, purity and microbial limits.

    Store in tightly closed, light-protected containers in a cool, dry, ventilated area away from heat, ignition sources and strong oxidizers.

    Confirm packaging with the requested quantity and destination requirements.

    Document requirements should be confirmed from the current specification, SDS, COA or other product-specific files.

    FAQ - Technical & Supply Chain

    • Q:

      What is Isopropyl Palmitate CAS 142-91-6?

      A: 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.
    • Q:

      How does isopropyl palmitate differ from isopropyl myristate?

      A: 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.
    • Q:

      What are the main applications?

      A: 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.
    • Q:

      Can it be used in anhydrous systems?

      A: 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.
    • Q:

      Which grade and packaging does this listing cover?

      A: 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.
    • Q:

      What specifications should be confirmed before ordering?

      A: 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.
    • Q:

      How should isopropyl palmitate be stored and handled?

      A: 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.
