It is composed of calcium stearate, magnesium stearate and alkali metal derivatives from the fatty acids or moisturizers that are added to the soap. Minerals found in hard water, such as calcium, iron, and magnesium combine with the chemical substances in the soap, creating a thick, white residue that latches onto skin.
This film refuses to dissolve, making it feel sticky, slimy or even dry. Bar soap residue left behind after a bath or shower will make skin feeling sticky. Therefore, it is very important to use clean-rinsing soaps and preferably soft water with natural ingredients.
While bar soap is very effective at removing dirt and germs from your skin, it can also strip the skin of natural oils.
Bar soaps have a higher pH level than liquid soaps or body wash, which can result in dry skin. Dried-out skin feels tight and uncomfortable. A study has shown that soaps with a high pH have a dehydrative effect on skin can lead to itchy dry skin turning flaky and tight. It is also less likely to heal itself without the aid of a topical moisturizer or treatment. The International Journal of Cosmeti c Science says your skin average pH is below 5 so when choosing a soap with a Ph that is 5 or lower.
Most solid soaps have a pH level of 9 or 10 which can be harsh on the skin, removing essential oils necessary for health and renewal. Body wash is a liquid cleanser with a lower pH, which makes it gentler on skin. Lower pH cleansers also tend to rinse away easier, leaving less of a residue or film behind. A bar like Dove , for example, has a low pH level around 6 so it will not dry out the skin or leave it feeling sticky. A soap-like Zest , on the other hand, has a high pH level around 10 so it is more likely to leave skin feeling tight, dry and coated.
Below is a list of common soaps and their pH levels:. It is the number 1 dermatologist recommended brand on the market today and is hypoallergenic, cruelty-free, fragrance-free, dye-free, sulfate-free leaves no sticky, soapy residue.
I never have this problem with body wash. At most, I would only drop the loofah. I remember a time when it took about two or three times to pick a bar of soap back up.
It was wet, soapy, and slippery. It seemed to just hop right out of my grasp. Eventually, I would be successful and get it. It could slip out of my hands again this way! More specifically, when soap gets wet, water makes contact with the hydrophobic tails of the soap molecules.
Hydro is another name for water or having properties involving water. And phobic is, well, the first thing I think of is a phobia. Is the soap afraid of water? No, but it does get slippery when wet. What is handmade soap, really?
Well, one answer would be it has similar properties as regular soap. Soap is made of long-chain fatty acids. The chains are made of carbons and hydrogens. The chain of fatty acids—the carbons and hydrogens—has both repelling and attractive properties when it comes to water. And when the soap makes contact with water, it activates these properties at the same time.
Have you ever gotten olive oil on your fingers? Maybe you have been to a restaurant and have eaten bread, cheese, and olive oil. It can be messy and you can get olive oil and your fingers. So the next time someone tells you the soap is really slippery, just say this: The soap is slippery due to the properties of the carboxylic acid functional group.
The best part is their reaction to you after you say that. They might think you are a genius! When it comes to soap, now you are. Yes, sticky soap will make you sticky; however, washing the soap off will make you less sticky. Even the stickiest soap can be washed off with enough water. Hard water creates the stickiest soap. My suggestion, if you have hard water and are bothered by soap scum feeling and don't want to use dove, would be to try find a shower gel that doesn't have any soap in it most don't Detergents don't react with hard water the same way soaps do, and should provide you with a "soap scum free skin" feeling Not all detergents are petrol based, some are based on coconut oils As long as it's blended in the right concentration.
After all a little orange oil can add some nice flavor to a food, but concentrate it, and you have a very nice degreaser A hand made soap will somewhat counteract the sticky feeling because of the glycerin in it Also some base oils will react slightly less than, say, sodium stearate, with the hard water, which can lead to a little less soap scum on the skin. You might give 1 or 2 different artisan soaps a try to see how they work with your water.
I couldn't have said it better myself techjunkie, thank you. Thanks techjunkie. You apparently remember you organic chemistry better than I do. ChemErik , Jun 23, And to give you an idea between soaps like Ivory and Dove and a handmade soap. Ivory soap has: sodium tallowate, sodium cocoate or sodium palm kernelate, water, sodium chloride, sodium silicate, magnesium sulfate, and fragrance. It's soap with the glycerin removed and milled under high pressure in commercial machines.
The product's slogan, " Yes they float, because air is mixed into them. The fragrance is citronella. Dove is a synthetic bar and not a true soap. It is, however made with beef fat and a masking fragrance. In the commercial, the film on the glass they are talking about is from the natural glycerin in the soap not soap scum Glycerin helps retain your own body moisture and also draws moisture to you. However, commercial soaps, mostly detergents, strip your skin of all its oils.
That is why you usually need to use a moisturizer after washing.
