Palmitic Acid Palmitic Acid is a saturated fatty acid naturally found in palm oil, coconut oil, animal fats, and many plant oils. In cosmetics, it is commonly used as a thickener, emulsifier co-ingredient, surfactant raw material, and emollient. Palmitic Acid Description INCI Name: Palmitic Acid Chemical Formula: C₁₆H₃₂O₂ Appearance: White to off-white waxy flakes, beads, or powder. Solubility: Insoluble in water; soluble in oils and alcohols. Origin: Can be derived from vegetable oils (commonly palm oil) or animal fats. Benefits 1. Thickening Agent Increases the viscosity of creams and lotions. Helps create richer, more luxurious textures. 2. Emollient Helps soften and smooth the skin. Reduces moisture loss by supporting the skin's barrier. 3. Emulsion Stabilization Works with emulsifiers to improve stability. Helps prevent separation of oil and water phases. 4. Foam Enhancement Commonly used in soaps and cleansers to improve foam quality and creaminess. 5. Opacifying Effect Gives formulations a more opaque, creamy appearance. 6. Structural Agent Adds body and consistency to sticks, balms, and creams. Typical Usage Rates Product Type Usage Rate Creams & lotions 1–5% Rich creams/butters 3–10% Cleansers 1–5% Soap bars 3–15% Lip balms 1–10% Deodorant sticks 2–10% Hair conditioners 0.5–3% Formulation Notes Usually added to the oil phase and heated to melt completely. Typical melting point is around 62–64°C. Often used alongside fatty alcohols such as Cetyl Alcohol and Stearyl Alcohol for enhanced thickening. Can react with alkalis (such as sodium hydroxide or potassium hydroxide) to form soaps. Advantages Cost-effective thickener. Improves cream stability. Provides a rich skin feel. Naturally derived options are widely available. Versatile across skin care, hair care, and cleansing products. Typical Recommendation For a standard facial cream, 1–3% Palmitic Acid is often used to add body and improve texture without making the formula overly heavy. For richer body creams and butters, 3–5% is common.
