õlipõhised

Õlipõhised is a term used to describe substances whose main solvent or binder is oil or oil-derived components. The opposite is veepõhised (water-based). The term is common in several industries, including paints and coatings, cosmetics, inks, and cleaners, where the oil-based formulation imparts particular properties and handling requirements.

In paints and coatings, õlipõhised products such as oil-based paints and varnishes form a film primarily through oxidation of the drying oil. They typically offer strong adhesion, good leveling, moisture and chemical resistance, and a glossy finish. They usually dry more slowly than water-based formulations and require organic solvents for thinning and cleanup (for example mineral spirits). They also tend to have higher VOC emissions and may yellow with age, which affects long-term appearance.

In cosmetics and skincare, õlipõhised formulations rely on oils and oil-derived ingredients to provide slip, emollience, and moisturization. They can create a rich, lasting feel but may be perceived as heavy for some skin types and can clog pores for sensitive individuals. Removal commonly requires oil-based cleansers or appropriate solvents.

In inks and adhesives, oil-based variants are valued for durability, solvent resistance, and strong adhesion, though they may require specific drying conditions and solvent systems. Environmental and safety considerations, particularly VOC contents and flammability, influence their use and regulatory status.

Overall, õlipõhised formulations are chosen for durability, moisture resistance, and finish quality when solvent systems and safety controls permit, with a trend toward more environmentally friendly, low-VOC options in many applications.
