POTASSIUM CARRAGEENAN

Description

Potassium carrageenan is a versatile hydrocolloid derived from red seaweed, specifically from the Rhodophyceae class. This natural ingredient is widely used in skincare formulations due to its impressive water-binding properties and ability to form gels. As a potassium salt of carrageenan, it offers enhanced stability and solubility compared to its sodium counterpart.

In skincare products, potassium carrageenan functions as an emulsifier, thickener, and stabilizer. It helps create smooth, consistent textures in creams, lotions, and gels while improving product shelf life. The ingredient's moisture-retention capabilities make it particularly beneficial in hydrating formulations, helping to maintain skin's water balance and promote a plump, supple appearance.

Potassium carrageenan also exhibits mild film-forming properties, which can provide a protective barrier on the skin surface. This characteristic helps to reduce transepidermal water loss and shield the skin from environmental stressors. Additionally, its natural origin and low irritation potential make it suitable for sensitive skin formulations.

When incorporating potassium carrageenan into skincare products, formulators typically use concentrations ranging from 0.1% to 1%, depending on the desired viscosity and texture.
