Chemistry of cosmetics

There are thousands of different cosmetic products on the market, all with differing combinations of ingredients. Cosmetics are not a modern invention. Humans have used various substances to alter their appearance or accentuate their features for at least 10, years, and possibly a lot longer. Women in Ancient Egypt used kohl, a substance containing powdered galena lead sulphide—PbS to darken their eyelids, and Cleopatra is said to have bathed in milk to whiten and soften her skin.

By B. C men and women in China had begun to stain their fingernails with colours according to their social classwhile Greek women used poisonous lead carbonate PbCO 3 to achieve a pale complexion. Clays were ground into pastes for cosmetic use in traditional African societies and indigenous Australians still use a wide range of crushed rocks and minerals to create body paint for ceremonies and initiations.

Today, cosmetics are big business. Cosmetic advertising, previously directed mainly at women, is now targeting a wider audience than ever. We use cosmetics to cleanse, perfume, protect and change the appearance of our bodies or to alter its odours.

This distinction means that shampoos and deodorants are placed in the cosmetics category, whilst anti-dandruff shampoos and antiperspirants are considered to be therapeutics.

NICNAS works to ensure that chemicals used in consumer products do not cause significant harm to users or to the environment. In the case of cosmetics, every ingredient contained within the product must be scientifically assessed and approved by NICNAS before being manufactured or imported into Australia and before they can be used in consumer products.

Where appropriate, NICNAS sets limits on the level at which a chemical can be used in a product and also conducts reviews on chemicals when new evidence arises. Cosmetic products that make an additional therapeutic claim such as moisturisers that also lighten the skin are regulated by a different organisation—the Therapeutic Goods Administration TGA. Cosmetics and other personal care items must also be labelled in accordance with the Trade Practices Consumer Product Information Standards, Cosmetics Regulations This regulation requires that all intentionally added ingredients are listed on the product label, and is enforced by the Australian Competition and Consumer Commission ACCC.

Ingredient labelling Like the food industry, the cosmetics industry is subject to mandatory labelling requirements by Australian government regulations. Product ingredients must be listed on the packaging, on the product itself, or shown in some other way that allows the consumer to be informed. As with food labels, ingredients are listed in descending order by mass or volume.

The purpose of this mandatory labelling is to allow consumers to identify ingredients they might be allergic to, and to compare the ingredients in products claiming to have similar benefits. Products are classified as therapeutic goods rather than cosmetics when they claim to treat an ailment or modify a bodily process. Therapeutic goods are subject to different labelling requirements.

Unlike cosmetics, they are required to show only their active ingredients GLOSSARY active ingredients The ingredient that is responsible for producing the desired effect of a mixture of ingredients and for giving the product its main characteristic. The active ingredient is not necessarily the most common ingredient in a product. Antiperspirants and anti-dandruff shampoos fall into this category.

Cosmetic products are not required to demonstrate their effects scientifically in the same way that therapeutic products are. So consumers should be aware that many of the claims made for cosmetic products have not been scientifically proven to be true. In the United States alone there are approximately 12, unique chemical ingredients approved for use in the manufacture of personal care products.

A typical product will contain anything from 15—50 ingredients.Become part of our community of dedicated professional and student members today — join now.

Yet, when you think of chemistry you seldom think of cosmetology. The two are more closely related than you might think. All beauty products are made from combinations of chemicals and fall into the realm of chemistry. When you dye your hair, a chemical reaction takes place, transforming it from one color to another. To fully understand the products used in cosmetology you need to know some basic chemistry. Hair coloring has become a science. The correct combination of chemicals can make the difference between healthy hair and damaged hair.

To lighten hair, bleach is often used. Bleach works because of a chemical reaction between the developer, which is an oxidizing agent, and an alkalizing agent. These molecules are too large to wash out of the spaces they occupy. By understanding basic chemistry you can explain this process to a client with confidence.

The chemistry of makeup is a vast sub-specialty of cosmetology. Lipstick is made from a combination of waxes, oils, pigments colors and emollients skin softeners. The wax helps in the application process. The oil mainly Castor oil leaves a shiny coating behind, once dry, which is ideal for lip gloss.

Pigments provide lipstick a wide range of color choices. Emollients are used to condition and protect the skin. Knowing the chemical composition of cosmetics can help the cosmetician choose suitable products for their clients. Skin care is a billion dollar business and the science of skin care starts with chemistry. Terms such as surfactants, emulsifiers and emollients are used in conjunction with skin care.

The majority of skin care products have a water base. Water helps spread the skin cream. Surfactants are used to break up debris on your skin.The Adobe Flash Player is required for video playback.

Cosmetics are an excellent example of how discoveries in chemistry are part of our day-to-day lives. In fact, just reading the composition of any common cosmetic can become a chemistry class: water, emulsifiers, preservatives, thickeners, pH stabilizers, dyes and fragrances, combined in different ratios, for different purposes.

The use of cosmetics — that is, chemical compounds to improve our appearance — is not a recent phenomenon. It is said that the Egyptian queen Cleopatra bathed in milk, as a way to keep her skin beautiful and soft. Unfortunately, we now know that lead carbonate is toxic and it is possible that the pursuit of beauty cost the lives of some of these women. In many cases, these different cosmetic products have a strong component of scientific innovation, developed in modern research laboratories.

Suffice to say that the cosmetics industry was among the first to adapt the new features of nanotechnology through the use of nanoparticles to improve the quality of their products and satisfy the desires of its customers. Nanoparticles are particles of intermediate size on the scale between atoms and macroscopic materials. Something like a thousand times greater than the diameter of an atom or thousands of times smaller than the thickness of a hair.

Typical examples of the application of nanotechnology in cosmetics are dioxide titanium nanoparticles in sunscreens that give complete protection without the effect of a white layer on the skinthe use of solid lipid nanoparticles for slow release of fragrance in perfumes, or creating nanovesicles as carriers to provide a better penetration of the active ingredients on the skin.Did you know that in prehistoric times, early modern humans decorated themselves with natural pigments found in plants and fruits?

Interesting given the rising movement towards more all-natural makeup. In BC, the Chinese started painting their fingernails with colors extracted from natural sources. There is even evidence that shows cosmetics were very much in existence in ancient Egypt. The evidence of cosmetic products over the centuries is vast. The company first specialized in cosmetics formulated and designed for film. It is safe to say the tremendous impact Max Factor had and continues to have in the modern cosmetic industry is without question.

Another fabulous cosmetic innovation is the modern day mascara. Now inthe first commercial non toxic mascara was developed by a chemist and founder of Rimmel London, Eugene Rimmel. The U. Food and Drug Administration FDA requires all cosmetic manufacturers to place labels, clearly, listing ingredients in descending order of weight. Again, in learning the fundamentals about your choices in makeup, can reduce your chance of developing rashes, acne, even eye infections.

Firstly, most ingredients are intended to give the product its consistency and color. Basic classes of ingredients include coloring agents, bases, additives, and bulking agents. Secondly, each one of us has an individual skin chemistry. Now color is what usually comes to mind immediately when we think of cosmetics.

Whether it is to create a blue based red lipstick, a muted lilac eyeshadow, or a dusky rose blush, chemists combine specific dyes and pigments to achieve a certain color.

Chromium oxide, aluminum starch, manganese, iron oxide, mica, kaolin, silica, and titanium dioxide are just a short list of examples of mineral ingredients essential to our beloved favorites. Preservatives that kill microbes are an important additive in most makeup too. Many microorganisms reproduce rapidly in moist and warm solutions.

One of the two cosmetic products to keep your eyes on is foundation and mascara as they are an ideal culture medium for harmful microbes without preservatives. Fascinating right? I could spend days learning more about the science that goes into some of my favorite beauty products. This is so interesting! I wish I had that same passion for Gen Chem. Linking science to makeup was a great idea though!

This is so awesome! I had no idea at all. Thanks for sharing.Cosmetic chemists develop most of the beauty and cosmetic products that you see in the stores. A cosmetic chemist, also known as a cosmetic scientist or makeup chemist, develops and formulates skin care, personal care and color cosmetics for manufacturers.

The Basics of Cosmetic Chemistry

Typically, cosmetic chemists need at least a bachelor's degree but may find that a graduate degree is necessary for career advancement.

Cosmetic chemists develop, formulate and test cosmetic and skin care products. Depending on their area of specialization, as well as employer needs, they may work with product development teams, experiment with pigments to create new cosmetic shades and colors, make use of current research to develop functional skin care, test products for safety, supervise lab assistants and work to ensure sanitary manufacturing conditions. According to the U. Bureau of Labor Statistics, chemists usually must have at least a bachelor's degree in chemistry.

Those who wish to advance in their field, particularly if they want to move into research positions, will need an advanced degree.

Advanced degrees may also be a requirement for getting a position with a Fortune cosmetics manufacturer. Professional organizations, such as the Society of Cosmetic Chemists, also offer continuing education programs that help new and experienced chemists gain and improve their skills and knowledge.

Typically, cosmetic chemists work full-time and in clean, well-lit laboratories, according to the Bureau of Labor Statistics. Travel is sometimes necessary for research, meetings with clients or product development consultations. The BLS also notes that working in this field carries with it some risks, such as exposure to raw materials that might be irritating or toxic.

Following lab safety protocols can significantly minimize the chance of accidents or injury. This means that half of all chemists made more than this amount and the other half earned less. A survey of chemists by PayScale. Cosmetic scientist jobs are expected to grow by 6 percent between and The BLS notes that chemists that have advanced degrees will have the best opportunities. It also recommends that current chemistry students try to get a job or internship while in school as real-world experience can be important when applying for jobs after graduation.
