They tend to be made of plant oils and natural herbal fragrances instead. You can even make them at home! So to sum things up, chemicals are bad for us. Manufacturers fill their skincare products with chemicals and then try to distract the consumer from noticing, by using misleading packaging and language. There is no regulation. If switching all your products seems like a daunting task, try cutting one toxic product out of your routine a month. By altering our consumer habits and continuing to demand chemical-free products, we can greatly diminish and even reverse the damage done to our bodies by exposure to toxins.
We can feel good about putting less toxic chemicals down the drain, too! Awesome article I really enjoyed it!

In the Ranks of the C. Surface tension is the result of cohesion which is defined as the "sticking-together" of particles. It is the attraction of particles to one another at the surface of a liquid. While all liquids have some sort of surface tension, the stronger the forces between the molecules intermolecular forces , the greater the cohesion.
Water has strong intermolecular forces --they are the hydrogen bonds described above. So, whenever you hit the water, you have to break the surface tension of the water to enter. When you dive or jump into a pool you break through a small amount of the water with your hands or feet. Picture from: slideshare. Watch the small video below and notice how the water droplets that I place on waxed paper bead up into tiny dome-like balls due to surface tension. Then see what happens to the surface tension of the water when I introduce some soap.
Soap is a natural surfactant , which is short for "surface active agent. Water will normally hold to itself because each water molecule is surrounded by and attracted to other water molecules. The property of surface tension causes water to bead-up on surfaces, like my wax paper. In order for the water to spread and wet a surface like your skin — you need surfactants. Soap molecules have two very different ends, the end that likes to stick to water is called the water-loving or hydrophilic end and the end that repels water is called the water-hating or hydrophobic end.
The soap molecule acts as a connecting bridge. I ts hydrophilic end attaches to a water molecule and its hydrophobic end attaches to a greasy dirt or oil molecule. When you rinse the soap off of your skin, the hydrophilic water-loving end ends of the soap molecule gets washed away with the water and takes the hydrophobic ends with the dirt and oil along with it.
Since our blog, "How Does Soap Work" discusses the process by which soap works to clean your body, I will not repeat the whole process here! When natural soap mixes with water it has a tendency to create thin sheets in which a thin layer of water molecules is sandwiched between two layers of soap molecules. The soap molecules actually trap water in a thin layer, creating a film like that seen in the picture to the left.
Picture from: itsokaytobesmart. Notice how the layer of blue and yellow water molecules is surrounded on either side by soap molecules with the hydrophilic end red pointed towards the water, and the hydrophobic tail pointed away from the water. Turning off the faucet after wetting hands saves water, and there are few data to prove whether significant numbers of germs are transferred between hands and the faucet.
Using soap to wash hands is more effective than using water alone because the surfactants in soap lift soil and microbes from skin, and people tend to scrub hands more thoroughly when using soap, which further removes germs 2 , 3 , 7 , 8.
To date, studies have shown that there is no added health benefit for consumers this does not include professionals in the healthcare setting using soaps containing antibacterial ingredients compared with using plain soap 9 , This rule does not affect hand sanitizers, wipes, or antibacterial products used in healthcare settings.
Lathering and scrubbing hands creates friction, which helps lift dirt, grease, and microbes from skin. Microbes are present on all surfaces of the hand, often in particularly high concentration under the nails, so the entire hand should be scrubbed Determining the optimal length of time for handwashing is difficult because few studies about the health impacts of altering handwashing times have been done. Of those that exist, nearly all have measured reductions in overall numbers of microbes, only a small proportion of which can cause illness, and have not measured impacts on health.
Solely reducing numbers of microbes on hands is not necessarily linked to better health The optimal length of time for handwashing is also likely to depend on many factors, including the type and amount of soil on the hands and the setting of the person washing hands. For example, surgeons are likely to come into contact with disease-causing germs and risk spreading serious infections to vulnerable patients, so they may need to wash hands longer than someone preparing their own lunch at home.
Nonetheless, evidence suggests that washing hands for about seconds removes more germs from hands than washing for shorter periods 15 , 17 , Accordingly, many countries and global organizations have adopted recommendations to wash hands for about 20 seconds some recommend an additional seconds for drying :.
Soap and friction help lift dirt, grease, and microbes—including disease-causing germs—from skin so they can then be rinsed off of hands. Rinsing the soap away also minimizes skin irritation Because hands could become recontaminated if rinsed in a basin of standing water that has been contaminated through previous use, clean running water should be used 1 , While some recommendations include using a paper towel to turn off the faucet after hands have been rinsed, this practice leads to increased use of water and paper towels, and there are no studies to show that it improves health.
Germs can be transferred more easily to and from wet hands; therefore, hands should be dried after washing 15 , However, the best way to dry hands remains unclear because few studies about hand drying exist, and the results of these studies conflict. Additionally, most of these studies compare overall concentrations of microbes, not just disease-causing germs, on hands following different hand-drying methods.
