DIY Deoderant

I don’t know about you, but, when you have French class with a lot of other people that have gym with you right before, we tend to be a little smelly, depending on the day’s activity. But, besides the obvious reasons why you wouldn’t want to smell, helping prevent sweat is also good. That’s why I wear deodorant, just like most people in our world. While it is your choice, here’s how to make your own deodorant, and the chemical background of it.

Many deodorants today are filled with chemicals that aren’t safe to use on broken skin. Sweating releases toxins, and we don’t want to be taking in some of the harmful chemicals in our deodorant like, “…aluminum, parabens, triclosan, talc, propylene glycol and phthalates, all of which are harmful when absorbed through the skin.”  Skin absorbs most everything, so, even if there is a warning not to put on broken skin, whatever is in it can still be absorbed. organic products, or ones made yourself, are most ;likely the best way to go, although many companies have started producing organic  or toxic-free deodorant, which is much healthier for you. 

One article states which common chemicals to avoid and why: “

  • Aluminum. Scientists are looking at the link between Alzheimer’s disease and aluminum. It could come in the following forms: aluminum chlorohydrate, aluminum zirconium tetrachlorohydrex gly or other aluminum compounds.
  • Parabens. This group of chemicals is widely used as a preservative in the cosmetic industry. Parabens can mimic the hormone estrogen, which is known to play a role in the development of breasts
  • Triclosan. Thought to contain carcinogenic contaminants which can be stored in body fat.
  • Talc. A known carcinogen, irritant, cause of lung asphyxiation and possible link to uterine cancer. On a softer note, it clogs pores and causes acne.
  • Propylene glycol. A neurotoxin that may cause liver and kidney damage.
  • Phthalates. Shown to damage the liver, kidneys, lungs and reproductive system in animal studies.

To check out some of the FAQ’s of deodorants, check out the link below! Now, onto how to make your own organic deodorant, so that you don’t have to look at teh long lists of ingredients on the back of deodorant in the supermarket.

Ingredients:

  1.  1/4 cup arrowroot powder (as a thickening agent)
  2. 1/4 cup baking soda
  3. 4 tbsp coconut oil (nice moisturizer!)
  4. 10+ drops grapefruit oil
  5. a jar or tin with a lid (to store it in)

Mix all of the ingredients together well. If you want, you can use a hand mixer. It should become a mixture with a balm-y consistency. To keep it solid, store in a relaticely cold place, like a fridge. And that’s it!

Now, she just said to apply the deodorant with your hands, but I think you could take a toothbrush, or a hollowed out chap-stick/deodorant tube and use that. Or you could get a sponge or something. get creative as you enjoy your toxin-free, and deliciously smelling, deodorant!

Being Brainy about Beauty

makeup

While I don’t really wear makeup, just some lip gloss and the occasional blush, I know many girls at my school who wear makeup (and sometimes too much!). Makeup is a huge industry, and  in the cosmetic field, the use of chemical resources is prominent in beauty products such as shampoos, eye shadows, and moisturizers.

In shampoos,  Glycol stearate is a thickener added to products like shampoos to give them a pearly appearance. Its sole purpose is to create a pleasant look.  Sodium lauryl sulfate is a surface-active substance which is also in shampoo, but it is also used in skin cleansers. It loosens dirt and oils, making it easier to wash them away. In mascaras, Lecithin, a lipid found naturally in plant and animal cells, is used as an emollient and moisturizing agent. It helps protect the outer layers of the epidermis against dryness and irritation. Titanium dioxide is used to lighten cosmetics such as eye shadow and foundation. Talc is also used in eye shadow and other powdery products for it is an absorbent natural compound.

Other substances added are:

  • agar: similar to algae; used in moisturizers.
  • alcohol SD-40: according to one website: “…a high-grade cosmetic alcohol that acts as an emollient and a vehicle for the other ingredients.”
  • cellulose: used as a thickener for creams and skin lotions
  • mica: a mineral found in toothpaste and other make-up products; creates a shiny, pearly look
  • parabens: used as a preservative in makeup and lotions
  • xanthan: a thickening agent used for texture

With so many different products these days, it’s hard to really know what’s in your products.  I found this very interesting because I did not know that many of the products that I use in my daily routine are based on chemistry. Without these substances the field of cosmetics would not be as advanced as it is today.  While most things in products are designed to help you, always be on the lookout for something trying to con you!

Bubble-licious!

When you were little, you probably had a lot of fun with bubbles. You probably got the most prized to some kind of game or as party fever. But whatever the reason, kids everywhere love bubbles and I am no different. So maybe I don’t put them in my bathtub or always blow them outside whenever I get the chance, but I am very entertained by bubbles. So I figured, why not do a blog post about bubbles!

A bubble is a thin film of soapy water. Bubbles are not just filled with air but they can also be filled with carbon dioxide or other gases. Bubbles have three layers. One layer of water is put between two other layers of soap molecules. According to one article, “Each soap molecule is oriented so that its polar (hydrophilic) head faces the water, while its hydrophobic hydrocarbon tail extends away from the water layer. No matter what shape a bubble has initially, it will try to become a sphere. The sphere is the shape that minimizes the surface area of the structure, which makes it the shape that requires the least energy to achieve.” 

But what happens when two bubbles meet?

Instead of trying to remain spheres,  the two bubbles will try  to become smaller so that their surface area lessens. If the two bubbles are the same size then the quote on quote wall that separates them will be flat. However if the bubbles are different sizes, then a smaller bubble will go into the larger bubble. Eventually, if you combine a bunch of bubbles, the cells will form the shape of a hexagon.

There are many different types of soap that you can use to make bubbles, but probably the best kind of soap would be detergents. “Detergents form bubbles in much the same way as soap, but detergents will form bubbles even in tap water, which contains ions that could prevent soap bubble formation. Soap contains a carboxylate group that reacts with calcium and magnesium ions, while detergents lack that functional group. Glycerin, C3H5(OH)3, extends the life of a bubble by forming weaking hydrogen bonds with water, slowing down its evaporation.” Never thought your childhood pastime contained so much chemistry, huh?

I love bubbles, and I know that you are never too old to play with bubbles. So if you are ever bored, grab some old bubbles or detergent and run outside. Go have fun!
