4. Excellent Formulation Stability

Highly resistant to oxidation and hydrolysis at room temperature, with outstanding chemical stability. It will not oxidize or produce off-odor during storage and application.

5. Outstanding Pigment Solubilizing Capacity

Serves as an excellent pigment solubilizer for color cosmetics, ideal for lipsticks, mascaras and other color cosmetic formulations.

 1. Skincare & Personal Care (Core Application)

Isopropyl Palmitate is one of the most classic emollient esters in synthetic raw materials, with a recommended dosage of 2% – 10% in formulations:

Skincare creams, lotions & body lotions: Delivers lightweight skin feel, fast penetration, improves skin softness and smoothness without greasy residue

Foundation creams: Enhances product spreadability, promotes uniform pigment dispersion and improves makeup application performance

Sun care products: Acts as a solvent to disperse UV filters, improves product skin feel and spreadability

Bath oils & shaving creams: As a non-oily emollient ester, delivers smooth and refreshing skin touch

2. Color Cosmetics & Hair Care

Lipsticks, lip balms & eyeshadows: Serves as a binder and solvent, improves powder dispersion and delivers excellent spreadability; acts as an ideal pigment solubilizer for lipstick formulations

Mascaras: Excellent pigment solubilizer for mascara formulations

Hair conditioners & hair oils: Imparts hair gloss, improves combability and reduces frizz

3. Pharmaceutical & Medicinal Excipients

Transdermal drug delivery systems: As a pharmaceutical excipient for ointments, creams and topical formulations, it enhances drug permeability and bioavailability

Pharmaceutical solvent & carrier: Serves as a component of semi-solid bases, solubilizes a wide range of active pharmaceutical ingredients

4. Other Industrial Applications

Fragrance solubilizer: Improves fragrance dispersion and stability in formulations

Textile auxiliaries: Serves as a softener for fiber treatment

Pesticide intermediates: Acts as a solvent and carrier for pesticide formulations

Q1: What is Isopropyl Palmitate, and what is its standard global identifier?

A: Isopropyl Palmitate (INCI: Isopropyl Palmitate, industry abbreviation IPP, CAS 142-91-6, alias Isopropyl Hexadecanoate) is a low-viscosity synthetic fatty acid ester produced via esterification of natural palmitic acid (derived from palm oil/coconut oil) and isopropyl alcohol. It appears as a colorless, nearly odorless transparent oily liquid above 15°C, and is one of the most classic emollient ester raw materials in the global cosmetic industry.

Q2: What core functions does Isopropyl Palmitate serve in formulations?

A: IPP is a multifunctional raw material with 5 core roles:

Emollient & moisturizer: Delivers soft, smooth skin feel with long-lasting moisturizing effect

Solubilizer: Excellent solubilizing capacity for pigments, UV filters, fragrances and active ingredients

Thickener & binder: Improves formulation consistency and powder adhesion in cosmetics

Lubricant: Reduces friction and improves spreadability of products

Penetration enhancer: Improves skin absorption of active ingredients

Q3: What is the recommended usage level of Isopropyl Palmitate?

A: The standard recommended dosage of Isopropyl Palmitate is 2% – 10% for most cosmetic and personal care formulations. Dosage can be adjusted according to product type: 2-5% for lightweight lotions, 5-10% for creams, color cosmetics and sun care products, and adjusted accordingly for pharmaceutical and industrial formulations based on process requirements.

Q4: In which products is Isopropyl Palmitate commonly applied?

A: As a highly versatile ester raw material, IPP is widely used across 4 major industries:

Skincare & personal care: Creams, lotions, foundations, sunscreens, bath oils, shaving products

Color cosmetics: Lipsticks, eyeshadows, mascaras (as pigment solubilizer and binder)

Pharmaceuticals: Topical ointments, creams and transdermal drug delivery systems

Industrial applications: Fragrance solubilizers, textile softeners, pesticide carriers

Q5: Why is IPP particularly preferred for color cosmetics like lipsticks and mascaras?

A: Isopropyl Palmitate is the preferred raw material for color cosmetics for two core advantages:

Outstanding pigment solubilizing capacity: It effectively dissolves and disperses cosmetic pigments, ensuring uniform color development and stable formulation

Excellent spreadability & adhesion: It improves product glide, enhances makeup adherence, and delivers a comfortable non-greasy feel on skin and lips

Q6: What is the stability performance of Isopropyl Palmitate?

A: IPP has excellent chemical stability: it is resistant to oxidation and hydrolysis at room temperature, will not oxidize or produce off-odor during storage, and maintains stable performance across a wide pH range. It solidifies at low temperatures (below 15°C) and returns to liquid state after gentle heating, with no impact on product performance.

Q7: Is Isopropyl Palmitate compliant with global regulatory standards?

A: Yes, IPP is a globally approved raw material:

Cosmetic use: Approved by CIR Expert Panel, compliant with EU, US and China cosmetic regulations, with a long history of safe use in personal care products
