Re: Faso Soap - The antimalarial soap. Is it really working?

Dear Maite,

Franck Langevin from Faso Soap Team also replied to your question. You could find his contact data on Knowledge Point (knowledgepoint.org/en/questions/3577/fas...er=3647#post-id-3647):

I am working on the Faso Soap project and I can therefore give you news about our mosquito-repellent soap. I agree with what Jo and James said in the previous post. We are still in a R&D phase. We are eagerly working to make this repellent soap a reality. Next month we will start conducting trials in an independent research center using WHO compliant protocols to assess the respective repelling effects of different prototypes we created. This shall give us scientific probe about the effectiveness of using a soap to repell mosquitoes. We are about to release a new version of our site (www.faso-soap.info) to publish more updated about the project. We would be delighted to keep in contact with you personally to give you updates.

Franck Langevin

Re: Faso Soap - The antimalarial soap. Is it really working?

Thank you very much for all these answers. I do agree with the points raised and the concerns regarding its effectiveness. It really seems the soap might not be a single solution for stopping mosquito bites, but a complementary solution to other vector control solutions.

It seems the Faso-Soap team might be doing some trials this year. It might also be interesting to know the composition of the soap.

Thanks again,

maite

Re: Faso Soap - The antimalarial soap. Is it really working?

The website for this project/product is www.faso-soap.info/

If the objective is to repel mosquitoes, an insect repellent would seem like the more effective choice. That is applying known/monitored amounts of repellent to exposed skin and thin clothing will provide more/longer protection than varying amounts just on the hands or washed skin surfaces.

A search tool and database are available on USEPA's cfpub.epa.gov/oppref/insect/ for various insect repellents.

Re: Faso Soap - The antimalarial soap. Is it really working?

Dear Maite,

We put your question on Knowledge Point and this is the reply we received from Jo Lines and James Logan of the London School of Hygiene and Tropical Medicine (find the answer also in the Knowledge Point Q & A Forum knowledgepoint.org/en/questions/3577/fas...er=3620#post-id-3620)

Posted on behalf of Jo Lines and James Logan of the London School of Hygiene and Tropical Medicine

This product is receiving tons of attention in the media, and has won some 'social innovation' prizes. So far, however, there appears to be no clinical data demonstrating effectiveness, and I am not aware of any entomological data.

The ingredients have not been made public but include lemongrass, so it is possible to believe that there might be some effectiveness. On the other hand, the presence of lemongrass does not mean it probably works. Yes there are lots of essential oils that have some repellent activity, and that can be used against nuisance biting, but this doesn't imply effectiveness against malaria. Yes there are some trials showing that when effective skin-repellents are used as an addition to ITNs, they can give additional epidemiological protection against malaria. Some of the best evidence comes from Bolivia and Pakistan. But it's important to remember why they went to Bolivia, why they tried it in Pakistan: these are places where the local malaria vector Anopheles species bite very early in the night: transmission is more or less over by 9pm. You can't use that evidence to argue for probable effectiveness in Africa, where 80% of transmission still occurs between 10pm and 4am.

Years ago, there was a locally-produced soap formulation of the pyrethroid permethrin; there was some enthusiasm about it, and it was around for a few years, but without finding very widespread success. Soap can be a convenient and stable formulation to manufacture, but there is an obvious problem in use: you normally rinse soap off the skin quite thoroughly a few seconds after you put it on. You can advise people to lather it on and not rinse it off, let it dry on the skin, but will they do that?

In cases like this, the intention and the initiative deserve to be encouraged, and it is good to provide funding for testing. But we must be careful that enthusiasm for the idea and the research does not go too far. What I see, on some websites, is that the object of celebration is not only the idea and the research, but also the stuff itself, the product. There is no statement that the product has been tested and found to be effective, but equally there is no qualifying statement that effectiveness remains unknown or unproven. Several news websites report that the product contains a known repellent, and one university site refers to it as a "low-cost anti-malarial tool". So it is easy for a reader to assume that the product probably is effective, even if the formal trials are not yet complete.

It is obviously dangerous to rely on an untested product for protection against a deadly disease, and anything that might encourage people to do this is to be avoided. Let's celebrate the intention, but let's not assume a product really does protect against malaria until it has been shown to do so. That requires careful epidemiological trials in the setting where it is to be used.

Faso Soap - The antimalarial soap. Is it really working?

Hi all,

I was wondering if any of you have some updates about the Faso Soap - The antimalarial soap. Is it really working? Could we purchase it, or fabricate it?

If someone has some additional information I would greatly appreciate!

Thanks so much,

Maite
