nongreasy

Nongreasy is a descriptive term used in product labeling and consumer discourse to indicate that a substance or product does not leave a noticeable greasy or oily residue after application. It is often spelled nongreasy or non-greasy, with the latter variant more common in some regions. The term is widely used in cosmetics, personal care, and skincare advertising to convey a lightweight, fast-absorbing, and matte or non-shiny feel.

In cosmetics and skincare, nongreasy formulations aim to spread easily, absorb quickly, and leave skin with little to no visible shine. This attribute is frequently associated with products such as moisturizers, sunscreens, serums, cleansers, and leave-in conditioners. In hair care, nongreasy finishes describe products that do not weigh hair down or leave a sticky residue. In all contexts, nongreasy does not denote absence of moisture or benefits; rather, it describes sensory performance.

Formulation strategies to achieve a nongreasy feel include the use of volatile or fast-evaporating solvents, lightweight esters (for example isopropyl myristate), silicone-based ingredients with a low residue (such as cyclopentasiloxane), and gel or water-rich bases with minimal occlusivity. Texture enhancers like microfine powders or starches can also reduce perceived greasiness.

Assessment of nongreasy performance is subjective and often evaluated through consumer sensory panels alongside instrumental measures of oiliness or residue on skin or hair. Regulatory guidance generally requires accuracy and not misleading claims.
