Nátriumpalmitát

Nátriumpalmitát is the sodium salt of palmitic acid. Palmitic acid is a common saturated fatty acid with a 16-carbon chain, often found in palm oil and animal fats. In its pure form, nátriumpalmitát is typically a white or off-white solid. It is an ionic compound, formed by the deprotonation of palmitic acid and its combination with a sodium ion.

This compound functions as a surfactant, meaning it has both hydrophilic (water-attracting) and lipophilic (oil-attracting) properties. This dual nature allows it to reduce the surface tension between different substances, such as oil and water. Because of this property, nátriumpalmitát is commonly used as an emulsifier, helping to blend ingredients that would otherwise separate.

Its applications are primarily found in the cosmetic and personal care industries. It is frequently included in soaps, lotions, creams, and shampoos. In these products, it aids in creating a stable emulsion, improving texture, and contributing to lathering properties. It can also act as a cleansing agent. While generally considered safe for use in these applications, like many chemical compounds, it can cause mild skin irritation in some individuals. Nátriumpalmitát is also sometimes used in the food industry as a food additive, often serving as an emulsifier or stabilizer, though its prevalence in food applications is less common than in personal care.
