If one accepts the meaning of natural as having a source in nature rather than being synthesized in a factory, then the animal, mineral & vegetable fats, oils & waxes, gums, sugar, mineral such as talc, kaolin, bentonite, hectorite, fuller’s earth, sulphur & mica, pearl essence, starches, rubber latex, placenta related extracts perhaps even alcohol derived by natural fermentation of carbohydrates & concentrates are all naturals.
The other synonym used for natural is organic, from a chemist point of view consider a substance organic if it is a carbon compound. Then all the oils, fats & waxes, emulsifiers, gums, polyols & their ether & esters, fragrance, soluble colorants etc. are organic. Then even most of the creams, lotions & oils are organic.
Most of the women believes that, natural or to some extent even organic is real, meaningful term when it comes to beauty products. But that’s not true – not yet anyway.
A natural product should be free from ” parabens, synthetic preservative, sulphates, animal products or any thing with suspected potential human health risk”.
Natural product should contain minimum of 95% natural ingredients.
In any case, natural certification shouldn’t be confused with safety testing (plenty of natural ingredient aren’t safe)
