Isopropyl Myristate
Grade Standard | IP |
Form | Liquid |
Purity | Greater than 99% |
Packaging Type | Drum |
Application | Cosmetics |
Iso Propyl Myristate (IPM) is an ester of isopropyl alcohol and myristic acid, commonly used in cosmetic and pharmaceutical formulations for its solvent, emulsifier, and penetration-enhancing properties. It is a colorless, odorless liquid that is highly effective in improving the spreadability and absorption of active ingredients into the skin. IPM is widely used in topical applications, such as skincare, haircare, and drug delivery systems, due to its ability to reduce the viscosity and enhance the performance of various active compounds.
Applications
- Skincare Products: Used in lotions, creams, and serums to enhance absorption and improve texture.
- Haircare Products: Adds to conditioners, hair oils, and styling products for smoother application and improved hair manageability.
- Pharmaceuticals: Common in topical ointments and transdermal drug delivery systems to enhance the penetration of active ingredients.
- Cosmetic Preparations: Often used in formulations for foundation, concealer, and other makeup products to improve spreadability.
- Anti-Inflammatory and Pain Relief Products: Used in topical analgesics for better penetration of active pain-relieving ingredients.
Key Features
- Penetration Enhancer: Boosts the absorption of active ingredients into the skin, making it a useful agent in transdermal drug delivery systems.
- Solvent: Efficiently dissolves and disperses both hydrophobic and hydrophilic active ingredients, improving formulation stability and performance.
- Improves Spreadability: Enhances the texture of formulations, ensuring smooth and even application.
- Non-Greasy Feel: Provides a lightweight, non-oily feel, making it ideal for products requiring a non-greasy finish.
- Solubility in Various Ingredients: Compatible with a wide range of oils, resins, and active ingredients, allowing for versatile use in formulations.
Cosmetic Uses
- Moisturizers and Creams: Improves the texture and spreadability while enhancing the penetration of moisturizing agents.
- Hair Conditioners and Oils: Helps active ingredients penetrate the hair shaft, improving nourishment and conditioning effects.
- Makeup Products: Used in foundations, concealers, and lipsticks for smoother application and longer wear.
- Transdermal Delivery Systems: Enhances the effectiveness of active ingredients in topical treatments, such as medicated creams and gels.
- Shaving Creams and Gels: Adds smoothness and helps the product spread easily over the skin.
