Hand Sanitizer Soap
Ithaca Soap Liquid is a lathery organic real soap with a 8-9 ph. It is non drying, leaving your hands clean and moisturized!
Why soap works:
Soap is made of pin-shaped molecules, each of which has a hydrophilic head — it readily bonds with water — and a hydrophobic tail, which shuns water and prefers to link up with oils and fats. These molecules, when suspended in water, alternately float about as solitary units, interact with other molecules in the solution and assemble themselves into little bubbles called micelles, with heads pointing outward and tails tucked inside.
Some bacteria and viruses have lipid membranes that resemble double-layered micelles with two bands of hydrophobic tails sandwiched between two rings of hydrophilic heads. These membranes are studded with important proteins that allow viruses to infect cells and perform vital tasks that keep bacteria alive. Pathogens wrapped in lipid membranes include coronaviruses, H.I.V., the viruses that cause hepatitis B and C, herpes, Ebola, Zika, dengue, and numerous bacteria that attack the intestines and respiratory tract.
When you wash your hands with soap and water, you surround any microorganisms on your skin with soap molecules. The hydrophobic tails of the free-floating soap molecules attempt to evade water; in the process, they wedge themselves into the lipid envelopes of certain microbes and viruses, prying them apart.
Below is a paper detailing why and how soap works, debunking the hand sanitizer myth.
State of the Art Report, Liquid Hand Soaps & the Covid-19 Virus
5/30/20 by Andrew Turco
U.S. consumers have been given a mixed message as to the best remedy for the daily prevention of the spread of the Covid-19 virus, as it relates to hand cleaning. At present, there are three options upon which no final judgement or recommendation has been made: 1) Alcohol based hand sanitizer, 2) non-alcohol based hand sanitizer, and 3) frequent hand washing with any commercially available liquid, bar or foam soap. https://www.cdc.gov/handwashing/show-me-the-science-hand-sanitizer.html March 3, 2020. This article concludes that “Soap and water are more effective than hand sanitizers at removing certain kinds of germs, like Cryptospridium, norovirus, and Clostridium difficile. “Another telling statement: “If soap and water are not available, use an alcohol-based hand sanitizer that contains at least 60% alcohol.”
Pre Covid-19 research is more conclusive: https://ohsonline.com/articles/2019/09/30/studies-show-hand-washing-may-be-more-effective-than-sanitizer.aspx?admgarea=ht.InfectiousDiseases&m=1. Conclusion: “For people who don’t need to clean their hands multiple times a day during the workday, the CDC recommends washing them with soap and water when available and using sanitizer if it’s not.” The WHO published the following finding on April 4, 2020: “Water alone may rinse off dirt, but viruses and bacteria are so small they often need chemical and mechanical intervention to get their sticky nanoparticles out of crevices that make up our unique fingerprints. That’s why soap is so important. Its made for this job. Give soap 20 seconds, at least, of thorough scrubbing and the pin-shaped molecules will penetrate the types of bacteria and viruses, including Covid-19, that protect themselves with an oily lipid membrane. Like a nail popping a tire, the water-repelling end of the soap molecule, a hydrophobic tail that can bond with oil and fats, stabs Covid-19 and leaves the virus a deflated and broken sack of RNA cells.”
A March 23, 2020 article goes further:
file:///D:/Coronavirus%20all/USB%20Drive/Ithaca%20Soap/Washing%20hands%20with%20soap%20kills%20coronavirus.pdf:, with the following headline: “Soap is the most effective against viruses, “ and continues, Gels, disinfectants, wipes and creams containing alcohol (and soap) are alternatives with similar effect, but not to the same effect as regular soap primarily due to destabilization and removal properties of the virus from skin. Alcohol-based products include all “disinfectants” and “anti-bacterial” products containing a high share of alcohol solution, typically 60-80% ethanol , sometimes with a bit of soap.
An April 2003 article from the Journal of Community Health most conclusively addresses the issue: Short-And-Long Term Effects of Handwashing with Anti-Microbial or Plain Soap in the Community); in conclusion: “There were no significant differences in the initial sample between the group using anti-microbial or plain soap in the soap or plain soap in the proportion of samples that had the detectable log counts (7.2 or greater) either before handwashing (25.9% and 16.8% respectively, p=0.10) or after handwashing (25.4% and 19.4% respectively, p=0.29). “There were no significant differences between the groups using microbial or plain soap in self-reported frequency of handwashing or observed duration of handwash at either the baseline or after one year (all p> 0.07.)
The competition in the liquid soap market breaks into two categories: 1) the national branded and marketed products, and 2) the more regionally based family run manufacturers. Without going into too much detail, the nationally know brands make no supplemental claims concerning the efficacy or primacy of their liquid hand soap, in comparison to the other CDC recommended remedies (alcohol based hand sanitizers or non-alcohol based sanitizers.) Indirect inferences are made on some of the regional manufacturer web sites without siting the publicly available scientific literature which firmly substantiates what is clearly the CDC position at present: that hand washing with liquid soap is the most effective preventive measure that individuals can take to protect themselves from the spread of the virus. My recommendation is a more thorough literature review will even more substantially support this position, and strengthen the social media and web based information that Ithaca Soap can use to promote the efficacy of its product.
“They act like crowbars and destabilize the whole system,” said Prof. Pall Thordarson, acting head of chemistry at the University of New South Wales. Essential proteins spill from the ruptured membranes into the surrounding water, killing the bacteria and rendering the viruses useless.
In tandem, some soap molecules disrupt the chemical bonds that allow bacteria, viruses and grime to stick to surfaces, lifting them off the skin. Micelles can also form around particles of dirt and fragments of viruses and bacteria, suspending them in floating cages. When you rinse your hands, all the microorganisms that have been damaged, trapped and killed by soap molecules are washed away.
On the whole, hand sanitizers are not as reliable as soap. Sanitizers with at least 60 percent ethanol do act similarly, defeating bacteria and viruses by destabilizing their lipid membranes. But they cannot easily remove microorganisms from the skin. There are also viruses that do not depend on lipid membranes to infect cells, as well as bacteria that protect their delicate membranes with sturdy shields of protein and sugar. Examples include bacteria that can cause meningitis, pneumonia, diarrhea and skin infections, as well as the hepatitis A virus, poliovirus, rhinoviruses and adenoviruses (frequent causes of the common cold). These more resilient microbes are generally less susceptible to the chemical onslaught of ethanol and soap. But vigorous scrubbing with soap and water can still expunge these microbes from the skin, which is partly why hand-washing is more effective than sanitizer.
Reuse any bottle. For years I've been carrying a little bottle filled with Ithaca Soap Liquid in my purse, for hand washing on the go. I use it everywhere, even when I don't have access to water. A few drops rubbed into my hands and I'm good. Traditional oil based soap's high ph is naturally anti bacterial. When used with water this can be diluted up to 100%. I prefer it at full strength for hand washing, dishwashing. Dilute 1 & 1/2 bars of Liquid Soap Bars in a gallon of water for house cleaning. Then spray surfaces and wipe clean with no residue left behind.
