According to Statista, the global production of vegetable oils reached a peak of 229 million metric tons in 2024/2025. This ubiquity brings a common question for many home cooks: Is vegetable oil considered a light oil? The answer depends on how you define 'light,' as the term can refer to taste, color, or physical viscosity.

An oil's classification as drying, semi-drying, or non-drying is determined by its polyunsaturated fatty acid (PUFA) content. Due to its high saturated fat content, coconut oil is a non-drying oil that remains a liquid on the skin's surface, acting as an occlusive barrier to lock in moisture.

Over 70% of avocado oil is composed of heart-healthy oleic acid, a monounsaturated fat. Understanding what's the difference between cold-pressed and refined avocado oil is crucial for making the right choice, as their processing methods significantly alter their nutritional profile and best culinary applications.

The pH scale is specifically designed to measure the hydrogen ion concentration in water-based solutions. Because oil is a non-aqueous, hydrophobic substance, it cannot have a high pH in the traditional chemical sense, or any pH at all.

MCT oil, unlike standard coconut oil, remains in a liquid state at average room temperatures, a property that stems from its unique chemical structure. This characteristic is due to the process of fractionation, which isolates specific types of fat molecules.

The iodine value for linseed oil, a drying oil used in paints, typically ranges from 170 to 204, a significantly higher figure than the 6 to 11 recorded for saturated coconut oil. This dramatic difference directly illustrates what a high iodine value means in the world of chemistry and industrial applications.

The iodine value for coconut oil typically falls within a low range of 6 to 11, which is a stark contrast to other vegetable oils like olive or sunflower oil. This low iodine number directly reflects the oil's high level of saturated fatty acids and low degree of unsaturation.

At room temperature, sweet almond oil is indeed thinner and lighter than olive oil, a difference rooted in their chemical structures. This distinction affects their uses, from how they absorb into the skin to their performance in cooking.
