What are the primary components of a cream?

The primary components of a cream are water, oil, and emulsifier.

Water serves as the solvent and hydrator in the formulation, providing moisture and acting as the base for the cream. Oil contributes to the emollient properties, helping to soften and smooth the skin, while also providing a protective barrier. The emulsifier is crucial because it allows the water and oil to mix, creating a stable emulsion. This combination is essential for the desired texture and function of a cream, enabling it to deliver hydration and nourishment effectively to the skin.

The other combinations do not represent the foundational structure of a cream. For example, while some may contain glycerin or preservatives, the specific trio of water, oil, and emulsifier is essential for defining the formulation and functionality of creams.
