Product Overview

Sodium Stearate C-7 is a sodium salt of distilled, hydrogenated fatty acids, offering a broad range of functional benefits in various applications. This versatile ingredient is FDA-approved for use in food and personal care products, making it an ideal choice for formulators. It effectively emulsifies oil and water phases, creates stable and consistent mixtures, and provides thickening properties, enhancing the texture and viscosity of creams, lotions, and shampoos. Additionally, Sodium Stearate C-7 offers opacifying benefits, creating a uniform appearance in personal care products, and improves wetting properties, allowing for better spreadability and absorption of formulations.

Sodium Stearate C-7 can also be used as a gelling agent in gel deodorant sticks and other personal care applications. It exhibits relatively high solubility in hot polar solvents, making it easy to incorporate into formulations. This grade has a low odor, making it particularly suitable for skin care applications. As a long-chain soap, Sodium Stearate C-7 inherently consists of both hydrophilic and hydrophobic parts, allowing it to effectively interact with various ingredients. Overall, Sodium Stearate C-7 is a valuable ingredient for food and personal care formulators, offering a range of functional benefits and technical advantages.
