 Protection from COVID-19 – issue of the day
 Most common mode of transmission of SARS-
Cov-2
 Air-borne respiratory droplets (including those
attached to particulates) – droplet transmission
 Direct contact with infected persons
 Direct contact with infected surfaces

5. COMMON DISINFECTANTS
 Chlorine based – the most common disinfectant
 Sodium hypochlorite (NaClO)
 Calcium hypochlorite (Ca(OCl)2)
 Liquid chlorine
 Hypochlorous acid (HOCl)
 Alcohol (ethanol/iso-propyl alcohol) based
 Hydrogen per-oxide
 Ozone
 Sodium hypochlorite (liquid bleach) is the most
commonly used

6. Sodium Hypochlorite (Hypo)
 Generally available in concentrated form (~10-
12% available chlorine)
 Tend to disintegrate on coming in contact with
air
 Not human friendly;
 People exposed to hypo by inhalation of aerosols
causes coughing and a sore throat
 After swallowing hypo the effects are stomach ache,
a burning sensation, coughing, diarrhoea, a sore
throat and vomiting

7. Sodium Hypochlorite (Hypo) …
 Hypo, on skin or eyes, causes redness and pain
 After prolonged exposure, the skin can become
sensitive
 Hypo is poisonous for water organisms
 Hypo is mutagenic and very toxic when it comes in
contact with ammonium salts
 safety measures have to be taken to protect workers
and the environment while working with hypo
 Hypochlorites are very sensitive to organic matter
in the water and thus lose their germicidal powers
faster

8. Hypochlorous Acid (HOCl)
 Hypochlorous acid – WBC produce in our body
(as first step of immune response trigger)
 Because of relatively low molecular weight and
no charge, it is better able than the other
chlorine based disinfectants to penetrate the
microbial cell walls
 Vastly superior disinfectant – 80-100 times
more powerful than the sodium hypochlorite
 requiring lesser concentration and contact time to
achieve desired level of disinfection

9. Hypochlorous Acid (HOCl) …
 Lot more hypochlorite is needed to achieve the
same antimicrobial power as hypochlorous acid
 It is non-toxic, non-irritant, and non-corrosive at
proper usage concentrations
 Some of the use of hypochlorous acid also
include eye, wound healing and veterinary care
products

ADVANTAGES OF HYPOCHLOROUS
SOLUTIOIN
✅ Eco Friendly ✅ Non-Toxic
✅ Child Friendly ✅ Rinse free
✅ Animal Friendly ✅ Non-Sticky
✅ Alcohol Free ✅ Quick Drying
✅ No residues ✅ No unpleasant odours

 Alcohols can cause skin dryness, irritation, rashes, itching,
inflammation, and even cracking. Besides, alcohol
evaporates too quickly and, may, provide temporary
sterilization effect
 Commercial sodium hypochlorite, despite of its strong
disinfecting ability: the higher its concentration, the
greater it harms our bodies (e.g. irritating our eyes, skin
and respiratory systems)
 Food Grade, HOCL is recognised as food disinfectant by
FDA (USA)
 HOCl has been identified by the Japanese Ministry of
Health as having bactericidal function on food and
additives

12. Hypochlorous Acid (HOCl) …
Chemical Disinfection - Use of
Hypochlorous Acid
12
✅ Alcohol Free, Fragrance Free, Colorant Free, Rinse Free,
Non-Sticky, Non-Toxic, All Natural, Eco Friendly, Animal
and Child Friendly
✅ Its multipurpose usage allows it to be sprayed on the
desired surface to be sterilized, such as, hands, body,
clothing, toys, mobile phones, tableware, air, toilets, etc.
✅ Absolutely healthy and safe, non-toxic and alcohol-free,
mild and non-irritating, so pregnant women and babies can
use it with confidence
✅ Disinfection: Disinfects floors, kitchen counters, carpets,
car seats, pushchairs, high chairs, toys, play area, mobile
phones, shopping trolleys, door knobs, sports & gym
equipment, office desks, cinemas, bathrooms etc.

13. Hypochlorous Acid (HOCl) …

Hypochlorous Acid
13
✅ Deodorant: Neutralizes bad odour such as cigarette
smoke, athlete foot, shoes, gym equipment, pets, litter
boxes, garbage, sewage, vomit and many more
✅ Disinfection potential of HOCl is 80-100 times higher than
that of Sodium Hypochlorite with same concentration
(lower concentration and contact time produces better
results)
✅ Kills more than 99.99% of bacteria, germs and virus!
Thoroughly performs sterilization and sanitization
✅ HOCl gets reduced to “water” after every “action” making
it harmless to human bodies and environment
✅ Hypochlorous acid is so gentle that it has several uses in
the healthcare and medical space

14. Hypochlorous Acid (HOCl) …
Chemical Disinfection - Use of
Hypochlorous Acid
14
✅ It can be used to wash vegetables and fruits without any
damage to them
✅ It kills the bacteria in raw meat, fish, etc., without
changing their smell and flavour
✅ It does not produce any unpleasant odour
✅ It can be produced on-site from natural ingredients like salt
✅ As it can be freshly prepared every day, it’s consistency
can be easily maintained
✅ It does not contain any other added chemical which may
have harmful effects
✅ The disinfectant can be stored for a reasonable time
without it loosing its strength.

15. Hypochlorous Acid (HOCl) …
Chemical Disinfection - Use of
Hypochlorous Acid
15
✅ The hypochlorous acid is produced at near neutral (slightly
lower than neutral) pH. So, it is non-corrosive on metal
and other surfaces.
✅ It does not leave traces/residues on surfaces
✅ It is safe on plants, if sprayed on them, unlike other
chemical disinfectants (which if not properly diluted will
kill the plants)

16. Hypochlorous Acid – Production
Chemical Disinfection - Use of
Hypochlorous Acid
16
 Until recently it has not been possible to create
hypochlorous acid in a stable solution with a usable
shelf life
 Through electro-chlorination process (which
generates sodium hypo-chlorite when common salt
is used as input), with proprietary salt combination,
the hypochlorous acid can be produced on-site at
the concentration which can be easily controlled
 Use of titanium based electrolyser – ensures long life
of electrodes (> 5 years)
 Both continuous and batch systems available

17. Hypochlorous Acid – Production
Chemical Disinfection - Use of
Hypochlorous Acid
17
 Hypochlorous acid is a weak acid
 At a pH of between 5-6, the chlorine species is nearly
100% hypochlorous acid (HOCl)
 Desirable pH is 6-6.5, in which about 90% is HOCl
and remaining is hypochlorite
 The maximum achievable concentration is 0.8%
 For majority of disinfection applications, a
concentration of ~1000 ppm is most desirable.
 Custom configurations/capacities to suit differing
requirements is possible

18. Hypochlorous Acid Generator
Chemical Disinfection - Use of
Hypochlorous Acid
18
 HypoHome: Generator for small clinics, shops, homes,
etc.) – 1 litre/batch (~10 minutes)
 HypoGen: Batch type disinfectant generator for higher
capacities) – 80-3360 litre/day (~1000 ppm effective
chlorine)
 HypoInstagen: Instant type disinfectant generator) –
50-200 litre/hour (~1000 ppm effective chlorine)
 Auxiliary systems
 HypoSpray: Pressure Spraying System with Disinfectant
Generator (batch production) – 210-3360 litre/day
 HypoTunnel: Sanitizing tunnel/chamber with disinfectant
Generator (batch production) – 200-400 litre/day
