Make-up varies from a wide array of cosmetics such as lipstick, blush, liquid eyeliner, and so much more. Men and women alike have used make-up for centuries.

Cosmetic companies all over the world endanger the lives of animals to test toxicity and irritation of products. In order to test these characteristics, the products are placed on the skin and eyes of animals. If a rash occurs, or if the animal is in any pain because of the product, it is unsafe for human use.
After the animal is tested on, it. The various tests carried out on animals is not a guarantee for using cosmetics on our skin since animals react differently to certain chemicals as compared to humans. Cosmetics companies kill millions of animals every year in pursuit of profit.

These have the same chemical formula but a slightly different crystal structure. They are both used to provide a white pigment. The structure of rutile means that it has a higher refractive index GLOSSARY refractive index also called index of refraction, measure of the bending of a ray of light when passing from one medium into another which means that it gives a particularly pearly shine. Zinc oxide ZnO is also used to create white pigments. Additionally, zinc oxide is used to provide sun protection as it reflects and scatters UV radiation.
Shimmering effects can be created via a range of materials. Some of the most common ones are mica and bismuth oxychloride. It naturally forms in flaky sheets and these are crushed up into fine powders. The tiny particles in the powders refract bend light, which creates the shimmering effect common in many cosmetics. Mica coated with titanium dioxide gives a whitish appearance when looked at straight on, but then produces a range of iridescent colours when viewed from an angle. Bismuth oxychloride BiClO is used to create a silver grey pearly effect.
This compound occurs naturally in the rare mineral bismoclite, but is usually produced synthetically and so is also known as synthetic pearl. The size of the particles used to create pearly and shimmering looks affect the degree of glimmer the product has. The smaller the particle size 15—60 microns, where one micron is one millionth of a meter , the less lustrous the powder will be, and more coverage it gives. Larger particle sizes, up to microns, give a more glittery lustre and are more transparent.
No matter how effective a cosmetic may be, no one will want to use it if it smells unpleasant. Chemicals, both natural and synthetic, are added to cosmetics to provide an appealing fragrance. Manufacturers do not have to list these individual ingredients as fragrance is considered to be a trade secret GLOSSARY trade secret an invented formula, practice, process, design, instrument, pattern, commercial method, or compilation of information which is not generally known or reasonably ascertainable by others, and by which a business can obtain an economic advantage over competitors or customers.
There are over 3, chemicals used to formulate the huge range of fragrances used in consumer products worldwide. A comprehensive list has been published by the fragrance industry.
