how to produce air freshener at home

We are all aware how aesthetically unpleasant
our environments can be sometimes. This is
not good for man's health. The consciousness
of this fact inclined us therefore to design a
formula that kills or suspends unpleasant
smells in our cars, toilet, bathes or even
offices. This is used along with cleaning
detergent or even sprinkled on objects to give
or environment a pleasant odour.
CHEMICALS
i. SULPHONIC ACID: This is a dark brown
highly viscous liquid. It functions to
neutralize the caustic soda solution and
consequently create a room for perfume
absorption.
ii. CAUSTIC SODA: It is also called sodium
hydroxide. it exists as solid pearls. It has a
very high solubility in water, dissolving to give
basic solution. It functions to promote the
absorption of perfume by the mixture since the
perfume is of oil base.
iii. FORMALIN: This is a harsh-smelling
liquid. It is the disinfectant in the formulation.
Germs, bacteria etc. are eliminated by this
chemical. Formalin should be treated with
care as it is very harmful to the skin.
iv. COLORANT : This gives colour to the
formulation. It should be noted that just a
small amount of colorant is needed.
v. PERFUME: Perfume aromatises the mix
and confers pleasant smell on the product.
The type that appeals the manufacturer
suffices for the product.
CHEMICALS MEASUREMENT
Caustic soda pearls -------- 1 spoon
Soda Ash ---------------- 3 spoons
Sulphonic acid --------------- ½ cup
Formalin --------------------- 1 teaspoon
Water ----------------------- 4 litres
Perfume ------------------ to taste
Colorant --------------------- to taste
METHOD
Wash and drain mixer. Clean also your filter
with soap and rid it of dirt.
Measure the specified quantity of water into
the mixer and follow it with the specified
caustic soda pearls. Stir gradually to dissolve
the pearls. At this stage the solution is
expected to generate some heat. Then
measure sulphonic acid into the mixer and
increase your stirring rate.
Stir till it mixes completely with the caustic
soda solution. Now check the PH paper
correct if necessary, to ensure the acid is
neutralized. The PH must lie between 7 and 8.
Then add formalin and colorant. Stir well to
mix properly and finally add your perfume
which forms the base of this product.
Allow the solution to dissolve for 24hours then
filter the solution and package immediately
and cart for sales.
