Chemicals+in+Cosmetics

**SLA Biochem 10th Grade Quarter 3 Benchmark** By: Anna Roman, Brenda Chhin, Nia Berry, Ryan Francis **

Aim:  To thoroughly investigate a specific chemical used in everyday products, evaluate the health and environmental implications of using this chemical, develop a position on what actions, if any, are needed, and persuade others to take action. 

Abstract: **  The chemicals used in everyday cosmetics all appear safe but about the ones that are not? Our task today is to show you the different potentially dangerous chemicals found in various cosmetic products such as: Eye Shadow, Lip Gloss, Facial Wash, and Shampoo. Also to show the chemical, environmental, economic, and political effects of the chemicals. After reading and learning these facts, you tell us what your opinion on cosmetics in America. SLS also known as Sodium Lauryl Suphate and (SLES) Sodium Laureth Sulphate can easliy be found in shampoos, toothpaste and soaps. These to two chemicals are used as a Degreaser. As commonly used and seemingly safe as these chemicals seem, they actually come with side-effects such as: Skin-Irritation and a currently tested theory of forms of CANCER. SLS and SLES is also used as a FOAMING AGENT in some cleaning agents and in some garages for degreasing engines. Do you find it safe to be washing up with the same stuff used for cars? D4 Siloxanes is a major ingredient found in oil-free make up, lip glosses, lipsticks and deodorant with quick drying and high shine.But it can also be found in BREAST IMPLANTS. Side effects include links to uterine tumors and reproductive damage in various animals but has yet to be certified for sure if these effects can be found on humans. Though it is banned in Canada, maybe it is suggested that Americans continue to use this risky chemical in products so scientist can test on us?

**Siloxane** is a chemical compound made of R3SiO aka a hydrogen. It aslo is oxidised to silicon dioxide.D4 Siloxanes is a major ingredient found in oil-free make up, lip glosses, lipsticks and deodorant with quick drying and high shine.But it can also be found in BREAST IMPLANTS. Side effects include links to uterine tumors and reproductive damage in various animals but has yet to be certified for sure if these effects can be found on humans. Though it is banned in Canada, the chemical is still used on a mass amount in many products.



Face cleansers such as Suave, Nutrogena and Proactive contain a chemical called **Ethylacrylate and Butylated Hydroxytoluene.** Although your skin may be looking healthy, young and has the best tone ever, get ready for some peeling before you get to that stage. It's also a skin irritant and eye irritant, so basically if used wrong, your eyesight could be impaled as well as rashes on the skin, if applied in the mouth or nose and also heavy peeling. And even though your cured of pimples and have fresh skin, you won't like the after effect at all. And also it's EXTREMELY dangerous to be wearing these creams/cleaners around open flames and fires. this chemical is highly flammable and if used wrong, and inhaled heavily could cause inflation in the body. If swallowed could cause cancer in the body.

**Diazolidinyl or ** **Imidazolidinyl urea ** is the second most identified cosmetic preservative. It's in every body-caring and cosmetic product out there that we use including the basic eye and facial makeup, aftershave, nail, bath, hair, skin care products. This cosmetic ingredient is only safe up to a max. concentration of 0.5%. One of the first things I learned that alarmed me was that the government, by law, isn't responsible for testing or approving any beauty or skin-care products. They are not responsible, the Cosmetic firms are responsible for their products and their ingredients that are marketed in the U.S food and drug. It may contain carcinogenic impurities and is associated with other significant health problems. Some people have a contact allergy to imidazolidinyl urea causing dermatitis. Such people are often also allergic to diazolidinyl urea. But there are products that you can use, that is environmentally friendly to the skin and gets you less paranoid about this chemical such as Burt's Bee. **-** **Molecule formula**: C11H16N8O8 This chemical releases formaldehyde and acts as a preservative.  

SLS actually stands for sodium lauryl sulphate and SLES stands for **S****odium Laureth Sulphate **<span style="font-family: Arial,Helvetica,sans-serif;">. They are both molecules and are very similar to each other; it is used in a lot of toothpaste, shampoos, and soaps. What it does, is it's used as a foaming agent and a degreaser. Even though it doesn't seem like it would do a lot, SLS and SLES can give you a lot of side effects. Such as, causing skin irritation, consumers say that it gets absorbed into your scalp and skin and can cause health problems. They are also some rumors saying that it may cause some types of cancer but nobody is positive of this side effect. I don't think they should use SLS in shampoos, toothpaste, and soaps because even though they are not 100% sure if it is really dangerous, there is still a chance and it isn't good. They also use SLS in some cleaning agents and in some garages for degreasing engines, I don't mind them using SLS/SLES in those thing but do you really want to wash your hair with the same thing you clean your engines and floors with? <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; line-height: normal;">**chemical formula** <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12px; font-weight: normal; line-height: normal;"> - CH3(CH2)11OSO3Na <span style="font-family: Arial,Helvetica,sans-serif;">
