no seawater is not H2O, only or pure water. But yes all the ‘ water ‘ in seawater is just plain H2O. Seawater contains a lot more then only H2O, it contains salt(s) minerals and biological materials like algae etc.

Seawater pH is limited to the range 7.5 to 8.4. The speed of sound in seawater is about 1,500 m/s (whereas speed of sound is usually around 330 m/s in air at roughly 101.3kPa pressure, 1 atmosphere), and varies with water temperature, salinity, and pressure.

What Is the Chemical Formula for Soap. For centuries, humans have known the basic recipe for soap — it is a reaction between fats and a strong base. The exact chemical formula is C17H35COO- plus a metal cation, either Na+ or K+. The final molecule is called sodium stearate and is a type of salt.

Soap is a combination of a weak acid (fatty acids) and a strong base (lye), which results in what is known as “alkalai salt,” or a salt that is basic on the pH scale. (See scale below) Sure enough, if you use a pH strip (also known as a litmus test) in soapy water, it often scores an 8 or 9.

The chemical formula of soap: RCOO – Na +, where R denotes any long-chain alkyl group containing 12 to 18 carbon atoms. Soaps are surfactants usually used for washing, bathing, and other types of housekeeping.

Toothpaste is a mixture of powdered solids and various liquids, so it’s neither a liquid nor a solid. Chemists would argue that toothpaste is a colloid (like milk or ink): a mixture where tiny particles of one substance are dispersed evenly into another without separating out.

In 2017, the Food and Drug Administration (FDA) declared that triclosan is not generally recognized as safe and effective for antiseptic products intended for use in health care settings.

Triclosan is a popular additive in many consumer products because it kills bacteria. Since the 1950s, it’s been added to hand sanitizers, toothpastes, cookware, gardening tools, clothes, toys, furniture, and even some baby teething products.

Brands and products containing triclosan include:

• 8 in 1 (Pet Shampoo)
• Bath & Body Works (AntiBacterial Hand Gel)
• Clean and Smooth (Liquid Soap)
• Clearasil (Face Wash)
• Colgate (Toothpaste)
• Dawn (Dishwashing Liquid, Liquid Soap)
• Dial (Body Wash, Liquid Soap)
• Edge (Shave Gel)

Recent studies have also found that Triclosan interferes with the body’s thyroid hormone metabolism and maybe a potential endocrine disruptor. Children exposed to antibacterial compounds at an early age also have an increased chance of developing allergies, asthma and eczema.

Toothpaste without Triclosan Crest Pro-Health toothpastes are formulated to deliver the same plaque and gingivitis benefits and more without Triclosan. With regular brushing, Crest Pro-Health toothpastes protect ALL the areas dentists check most.

Easy Ways to Avoid Triclosan Reduce your use of disinfectants, which may contain triclosan. For household cleaning, the surfactants in soap help lift the dirt off surfaces, while a little scrubbing and good rinsing will carry away the dirt (and any germs).

As a result, there is an anticipated decrease in the number of triclosan-containing products on the market with an associated increase in antibacterial alternatives (eg, benzalkonium chloride, benzethonium chloride, chloroxylenol, chlorhexidine) and cases of allergic and irritant contact dermatitis.

On September 9, 2016, the United States Food and Drug Administration (FDA) banned the incorporation of triclosan and 18 other antimicrobial chemicals from household soap products and the next year prevented companies from using triclosan in over-the-counter health care antiseptic products without premarket review.

In brands Dettol and Palmolive which do not contain Triclosan or Triclocarban also “wash’/’remove’ bacteria without “Killing’ them, which in any case is not what they claim. Hence these two brands might be relatively safer for the environment.

Drinking even a small amount of hand sanitizer can cause alcohol poisoning in children. (But there is no need to be concerned if your children eat with or lick their hands after using hand sanitizer.)

Some people have advocated that you should wash your hands after every four or five uses of alcohol-based hand rub. But, there is no reason to do this. If your hands feel ‘grubby’ or are visibly dirty, you should wash them with soap and water.

‘One of the main ingredients in many hand sanitizers is isopropyl alcohol. ‘Isopropyl alcohol is not safe for internal use, and if used whilst masturbating it could make its way down your vaginal or penile opening – this will damage the internal skin.

But there have been some suggestions using hand sanitiser and practising other hygiene measures too often could weaken our immune system, by reducing our body’s exposure to germs and with it the chance to “train” our immune defences. The good news is, there’s no evidence to suggest this will be the case.

Methanol and 1-Propanol Are Toxic There are many types of alcohol. Only ethyl alcohol and isopropyl alcohol (also known as 2-propanol) are acceptable alcohols in hand sanitizer. Other types of alcohol, including methanol and 1-propanol, are not acceptable in hand sanitizer because they can be toxic to humans.

The problem is that alcohol-based hand sanitizers can lead to dry skin, infection, and even alcohol poisoning….Dry Skin and Risk of Infection

• Itching.
• Slight to severe flaking, scaling, or peeling.
• Fine lines or cracks.
• Gray, ashy skin color.
• Redness.
• Deep cracks that may bleed.

There are also many other factors that can affect your immune health that aren’t related to hygiene. So here’s the big takeaway: There’s no evidence that a short-term boost in hand-washing and cleaning will reduce your body’s immune function.
