What you think? You believe in DETTOL products or whatever that says kill bacteria?

Generally, I buy Dettol soap because of the smell, smells similar to medicine. Not sure whether it kills bacterias or not.

I dislike those soaps with flowery or fruity smells. The other brand of soap I sometime use is Lux (because they are usually quite cheap)

They do work but some studies have shown that over-use of these products have led to a weakened immune defense system. This is because when you kill off all the germs, the body, especially in the young ones growing up, no longer knows how to deal with these nasties.

Some articles that cannot confirm ....

It seems like everything is "antibacterial" these days. About 75 percent of liquid soaps currently on shelves in American grocery stores display that word on their labels, and we are constantly adding new antibacterial products to our cleansing arsenals. So are we cleaner now than ever before? Some experts say no.
First let's take a look at how soap works on a chemical level. To make soap, you need to combine an acid and a base (or alkali). The acid is fat (fatty acids and triglycerides), and the base is sodium hydroxide (NaOH). The mixture causes the fatty acids to separate from the triglycerides and fuse with the hydroxide ions, forming a salt that we call "soap." Soap has two main functions:

Decrease water's surface tension
Bind to dirt, oil and bacteria
It can do these things because one part of the soap molecule is hydrophilic (water-binding) and the other is hydrophobic (water-repellent). The hydrophilic part allows the hydrophobic fatty acids to come into contact with other hydrophobic substances, such as the dirt on the surface that is being cleaned. When the grime adheres to the soap's fatty acids, it becomes encapsulated in droplets of water. Dirt, oil and bacteria are easily scrubbed off and washed away in this suspended state. So ordinary soap does get rid of bacteria. But does antibacterial soap get rid of even more?

Most liquid soaps in America are now antibacterial.
Possibly. But there are several main points to consider in our antibacterial craze:
The antibacterial components of soaps (usually triclosan or, less commonly, triclocarbon) need to be left on a surface for about two minutes in order to work. Most people are not this patient, and end up washing off the soap before the antibacterial ingredients can do their job.
Some scientists theorize that bacteria may develop a resistance to bactericidal agents over time.
Some bacteria actually benefit us. The normal population of bacteria on our bodies not only eats our sweat, but also helps defend us against truly harmful, invasive bacteria.
Many common diseases are viral in nature, anyway, and are therefore not prevented by antibacterial products.
According to the Centers for Disease Control and Prevention (CDC), antibacterial soaps are not necessary, but washing your hands thoroughly with ordinary soap and warm water is one of the most effective ways to ward off infection.

Study Disproves Antibacterial Soap Scare
Thursday, September 22, 2005

By Steven Milloy

"Antibacterial Soaps Are Safe, New Study Says," is not a headline that you should count on seeing anytime soon -- even though it's true.

We live in a world where sensationalized headlines promoting health scares are far more "newsy" than headlines about studies that debunk junk science or reassure us of consumer product safety. In short, good news is often not news.

And while the best part of this story is that a new study does indeed vindicate the safety of antibacterial soap products, I can't help but take some pleasure in knowing that regular readers of this column won't be at all surprised by the study result.

Researchers from the University of Michigan, Tufts University and Columbia University studied 224 households to determine whether household use of antibacterial cleaning and hygiene products is an emerging risk factor for the carriage of antibiotic-resistant bacteria (search) on the hands.

The researchers randomly assigned the households to use either antibacterial or non-antibacterial soap and cleaning products for one year. The active ingredient in the antibacterial products was triclosan (search), which has been found to be effective in reducing and controlling bacterial contamination when used properly.
The researchers reported in the October issue of Emerging Infectious Diseases that, "The results from our study do not implicate use of antibacterial cleaning and hygiene products as an influential factor in the carriage of anti-microbial drug-resistant bacteria on the hands of household members."

While the researchers also reported that they found no evidence indicating triclosan-containing antibacterial products work better than soap and water, the key point here is that there's no evidence that triclosan is contributing to the development of "supergerms" that would be resistant to antibiotics.

The health scare over triclosan-based antibacterial products was kicked off in the 1990s by Tuft University researcher Stuart Levy who, ironically, is one of the researchers on the new study. Levy authored an August 1998 study in the journal Nature reporting that widely used antibacterial consumer products caused genetic changes in bacteria.

Going beyond the scope of his study, however, Levy then speculated that these genetic changes could create dreaded "supergerms."

By July of 2000, the scare had caught fire to the point that the American Medical Association urged the Food and Drug Administration to expedite the regulation of antibacterial products -- even though, as I pointed out in my FOXNews.com column at the time, there was no scientific evidence that antibacterial products had caused any increase in antibiotic drug resistance, much less produced any "supergerms" despite more than 30 years of use in hospitals and homes.

Later that month, I appeared with Levy on CNN's Talk Back Live, where Bobbie Batista hosted a segment entitled, "Could Too Much Cleanliness Make People Sick?" Levy railed against triclosan-based antibacterial consumer products as unnecessary, improperly used and risky.

After pointing out that no scientific evidence or real-world experience indicated antibacterials were causing the harm alleged by Levy, I offered the audience a potential explanation for Levy's campaign against triclosan-based antibacterials.

Although Batista introduced Levy simply as the director of the Tufts University School of Medicine's Center for Adaptation Genetics and Drug Resistance and as the author of a book entitled, "The Antibiotic Paradox: How Miracle Drugs Are Destroying the Miracle," no mention was made of Levy's affiliation (vice-chairman, chief scientific officer and co-founder) with Paratek Pharmaceuticals.

Paratek was, and, according to its web site, still is working to develop its own antibacterial products for home use -- disinfectants that supposedly would "overcome the problems of antibacterial resistance." The company's web site states, "Paratek is well positioned to develop [antibacterial] products to serve this non-hospital consumer product market."

The frenzy over antibacterial products soon died down considerably and the scare has been on the wane ever since. Now Levy's name is even attached to a long-term study that reports no "supergerm" development in households using triclosan-based antibacterials.

But Levy may not have given up triclosan-bashing altogether. His study concludes with the statement, "However, more extensive and longer term use of triclosan might provide a suitable environment for emergence of resistant species. Further research is needed."

Levy's study is a double-edged sword, however. Since it also reports that antibacterial products for the home are no better than plain soap-and-water, the study may have inadvertently dashed his own company's commercial hopes by questioning the need for home-use antibacterial products in the first place.

Does Antibacterial Soap Work? At Least One Really Does.
Thu Mar 6, 2008 11:19am EST 

SCOTTSDALE, Ariz., March 6 /PRNewswire/ -- Hand washing is well recognized
as the primary defense against infection and illness.  As a matter of fact,
people wash their hands an average of 8 to 10 times a day, even more if
dealing with food, children, or equipment. This raises the question of whether
all soaps work equally well in the fight against germs and helping people stay
healthy.  The extraordinary results of a new study sponsored by The Dial
Corporation, a Henkel company, which were just published in the prestigious,
peer reviewed Journal of Food Protection, prove that not all hand soaps are
alike in their performance. In fact, this first of a kind, real-world study
showed that Dial Complete® Antibacterial Foaming Hand Soap's patented
antibacterial formula helps protect people from significantly more illness-
causing germs than ordinary soap.
    (Logo: here )
    Dial's method compared washing with Dial Complete® containing Activated
Triclosan™ Technology to washing with a plain liquid soap.  The hands of
the participants were first contaminated with the bacteria E. coli, which was
selected since it is commonly associated with foodborne illness, and previous
studies have correlated the quantity ingested to the probability of illness.
The participants' hands were then either washed with Dial Complete® soap or
a plain liquid soap.  They then handled melon balls and measured the quantity
of bacteria transferred from the washed hands to the melon balls.
    The results were nothing short of remarkable.  The Dial Complete® hand
wash was significantly better than plain soap and water at eliminating
bacteria from the hands.  Furthermore, compared to plain soap and water, the
Dial Complete® hand wash was up to 30 times more effective in reducing the
bacterial transfer from the hands to the melon balls.  Based on published
infection dose rates for E. coli, washing with Dial Complete® soap could
reduce your risk of disease by 45 percent over washing with a plain liquid
    The study concluded that the hand soap people choose can mean the
difference between staying healthy or falling prey to illness or infection. To
find out more, refer to the complete study Effect of Hand Wash Agents on
Controlling the Transmission of Pathogenic Bacteria from Hands to Food  by
G.E. Fischler et al, published in Journal of Food Protection, Vol 70, No. 12,
2007, pages 2873-2877.

technologies that make people's lives easier, better and more beautiful.
Henkel operates in three business areas -- Home Care, Personal Care, and
Adhesives Technologies -- and ranks among the Fortune Global 500 companies. In

I've read somewhere before quite sometime ago that

Chlorine + Anti Bactirial Soap = Poison. and it can be absorbed from skin ...

Please do correct me if i'm wrong

it does work to some extent, but significant or not, is another story. and for some products, they are too much of marketing gimmick.

they do use disinfectant to do deep cleaning in hospital, but sometimes, simply washing hand reduces c.diff transmission or use of alcohol based hand gel reduces MRSA transmission.

AB soap disrupts hormone activities,

A new UC Davis study shows that a common antibacterial chemical added to bath soaps can alter hormonal activity in rats and in human cells in the laboratory--and does so by a previously unreported mechanism.

The findings come as an increasing number of studies -- of both lab animals and humans -- are revealing that some synthetic chemicals in household products can cause health problems by interfering with normal hormone action.

Called endocrine disruptors, or endocrine disrupting substances (EDS), such chemicals have been linked in animal studies to a variety of problems, including cancer, reproductive failure and developmental anomalies.

The researchers found two key effects: In human cells in the laboratory, triclocarban increased gene expression that is normally regulated by testosterone. And when male rats were fed triclocarban, testosterone-dependent organs such as the prostate gland grew abnormally large.

This is the first endocrine study to investigate the hormone effects of the antibacterial compound triclocarban (also known as TCC or 3,4,4'-trichlorocarbanilide), which is widely used in household and personal care products including bar soaps, body washes, cleansing lotions, wipes and detergents. Triclocarban-containing products have been marketed broadly in the United States and Europe for more than 45 years; an estimated 1 million pounds of triclocarban are imported annually for the U.S. market.

I wonder what do the surgeons use to wash their hands before/after surgery. They scrub scrub very thoroughly. That soap should be the 'real' anti-bacteria solution.

Isn't that soap available for households? Imagine the tagline "SURGEONS USE THIS"... sell like mad

it is against ethics to use medical personal for commercial advert..

the soap they use are just your normal anti-bac soap... but they buy it cheap because it is for hosp use..

what's important is how you wash your hands... most soaps only works well if you use it properly

Any anti-bacteria spray like the cabin crew use on the plane? Is this a common item that we can find it in the 7-eleven shop?
