Fully synthetic是啥意思

"Fully synthetic" is a term that is used in various contexts, but it generally means something that is made entirely from synthetic materials or through a synthetic process. The meaning can vary depending on the field or context in which it is used. Here are some examples:

Chemistry: In chemistry, "fully synthetic" refers to a compound that is created entirely through chemical synthesis, rather than being extracted from natural sources. This means that every atom in the compound comes from a starting material that has been subjected to one or more chemical reactions.

Cosmetics: In the world of cosmetics, "fully synthetic" ingredients are those that are produced through chemical synthesis rather than being derived from natural sources like plants, animals, or minerals.

Oil: In the context of motor oil, "fully synthetic" oil is made from refined petroleum that has been further processed to create a lubricant with specific properties, such as a higher resistance to heat and better flow at low temperatures.

Furniture: When referring to furniture, "fully synthetic" might mean that the entire piece is made from synthetic materials, such as plastic or resin, rather than containing any natural materials like wood or leather.

Overall, the term "fully synthetic" implies that something is made from non-natural, human-made materials or through a process that involves the transformation of raw materials into a finished product through chemical reactions or other manufacturing techniques.
