Professional Chemist / FormulatorApril 28, 2020 at 11:51 am in reply to: Hydrogen peroxide for Coronavirus?@Doreen actually the most important thing is to know information between the concentration of hydrogen peroxide and needed contact time even for surface. But i really want to have hand sanitizer based on hydrogen peroxide.
@chemicalmatt thanks for share so do you think that 1,5 % hydrogen peroxide can be used for hand desinfection and what is the needed time contact for such concentration? -

Professional Chemist / FormulatorApril 19, 2020 at 6:37 pm in reply to: Can Ethanol 80 % be effective for Coronavirus?@Pharma I already read all about Sanitiser here and my question about the effectiveness of Sanitiser for coronavirus without both of glycerin and hydrogen peroxide never talked in forum.
I know that the only active ingredient in WHO sanitizer formulation is Alcohol however glycerin can be must have in WHO formulation cause it limits the evaporation of alcohol so may without glycerin alcohol will evaporate quickly and will not stay the needed contact time. (that is my scare about Sanitiser without glycerin) -

Professional Chemist / FormulatorApril 4, 2020 at 10:08 pm in reply to: Dettol and thymol are effective for Covid_19!!!@lmosca not really as you said, I see Dettol Antiseptic liquid in link from UK website and it is based on chloroxylenol 4,8%.

Professional Chemist / FormulatorApril 4, 2020 at 9:16 pm in reply to: Dettol and thymol are effective for Covid_19!!!@lmosca very intelligent view about which product of Dettol the site meant?
The most logic and reliable product about question the one you said, however I made reaserachement to discover all products of Dettol that can be effective for Covid_19 so the answer is found in UK Dettol website which said four other products of Dettol differents from Dettol brand hand sanitizer
Also in the site the active ingredient for Dettol’s product is chloroxylenol so as conclusion desired product is not Dettol brand hand sanitizer. -

Professional Chemist / FormulatorApril 4, 2020 at 7:37 pm in reply to: Dettol and thymol are effective for Covid_19!!!@lmosca interesting comment, however Dettol is found in list of approved hand sanitizers according to the site government of Canada https://www.canada.ca/en/health-canada/services/drugs-health-products/disinfectants/covid-19/hand-sanitizer.html#tbl1.
So according to you this site is not a reliable reference?Just recently I readed even Singaporean government approved Dettol as effective active ingredient for Covid_19.
About hydrogen peroxide which concentration is recommended (I see very different proposed level) and what is the needed contact time?

Professional Chemist / FormulatorApril 4, 2020 at 5:11 pm in reply to: Dettol and thymol are effective for Covid_19!!!No @Pharma Dettol is found in List of approved hand sanitizers. Thymol with low level is also safe for the skin as I guess.

Professional Chemist / FormulatorMarch 28, 2020 at 11:36 am in reply to: Hydrogen peroxide for Coronavirus?@Cafe33 really interesting link appriciate a lot your share but the table miss one important thing which is needed contact time.
@Pharma for sure scientifics don’t search for product which make a lot of pain. The product must have short needed time of contact ( seconds to few minutes it will be better just 1 minute which is a looked for one ) and also no or low irritant product for skin.
What about 3% hydrogen peroxide product I readed that it is effective for Coronavirus and it needs short needed time contact, any add about that? -

Professional Chemist / FormulatorMarch 27, 2020 at 7:14 pm in reply to: Urgent Help Required@em88 actually increasing percentage of alcohol will make product more effective and for Coronavirus WHO says that product contains 80% Ethanol or 75% IPA.

Professional Chemist / FormulatorMarch 26, 2020 at 6:55 pm in reply to: Soap is better for Corona virus?The best, easiest and sure formulation product for Coronavirus i found is 8,25 % hypochlorite Sodium and Qsp Distilled or deionised Water
So the benifits of product is sure product for Coronavirus confirmed by EPA with name ustin’s A-1 Concentrated Bleach 8.25% and it has quite short needed contact time ( 5 minutes) the product can be use for hands with Gloves, for vegetables, plastic, Stainless metals, woods, paper ….
However it has whitening effect for clothes, irritant for body and corossif for no Stainless metal…Professionals your turn to share.

Professional Chemist / FormulatorMarch 26, 2020 at 6:16 pm in reply to: Soap is better for Corona virus?Hi again professionals, so as alcohol not available in many countries is there any other effective product for hands (without washing means not soap solution when we are outside) for Coronavirus?
I Read a lot about diluted hydrogen peroxide, combination between sodium chloride and hypochlorite sodium, combination between sodium bicarbonate and sodium chloride, combination between sodium carbonate and hypochlorite sodium last one found in Environmental Protection Agency so it is for sure right however the product may have other ingredients.
Your share is duty which can save life of thousands of peoples.
