In some, yes. In others, no. Chemicals are not necessary in natural colored natural fibers. All that's needed in processing is a little soap and water. Yarns that are synthetic are basically made of chemicals. Yarns that are dyed have been treated chemicals, even if natural dyes are used.

Depends on the country but usually means they are flavors derived from natural chemicals (natural flavor) or artificial man made chemicals (artificial flavors). A natural flavor MAY be healthier but it MAY also be unhealthier than artificial flavors. Depending on the country some natural flavors may be a mix of artificial and natural chemicals. In fact, an orange natural flavor will most likely be a mixture of chemicals tat have no relation whatsoever to an orange, or possibly not even a fruit. As such it is a complete secret what the chemicals are and you are better avoiding natural and artificial chemicals altogether.
