This document outlines a science class lesson on chemical cleaning products. It begins with an introductory activity that quizzes students on different types of cleaners. The lesson then discusses the active ingredients in common household cleaners and the dangers of mixing certain chemicals. Students participate in a group activity to identify cleaners, their uses, and ingredients. The lesson emphasizes being aware of product contents and cautions against mixing bleach with other substances. It aims to teach students about chemicals safely through hands-on experiments and discussions.

9. LESSON OBJECTIVES:
• assess the usage and active ingredient(s) of
cleaning products used at home using realia
through observation;
• develop the value of teamwork, skepticism,
and humility to evidence by group activity,
and;
• discover the chemical properties, acidity and
basicity of chemical agents using the five
senses and litmus paper in a group
experimentation.

10. ACTIVE INGREDIENTS OF CLEANING
PRODUCTS USED AT HOME

11. HAVE YOU CHECKED WHAT’S INSIDE THE CLEANING
PRODUCTS THAT YOU USE?

12. The Dangers of Mixing Household Chemicals
• Be aware:
• Bleach + rubbing alcohol = chloroform.
Highly toxic. May lead to dizziness, nausea, loss of consciousness and even
death
• Bleach + ammonia = chloramine.
May lead to shortness of breath and chest pain.
• Hydrogen peroxide + vinegar = peracetic/peroxyacetic acid.
Highly corrosive. May lead to irritation of the skin, eyes, and respiratory
system.
• Bleach + vinegar = chlorine gas.
May lead to coughing, breathing problems, burning and watery eyes. (Chlorine
gas and water also combine to make hydrochloric and hypochlorous acid which may lead
to irritation of nose/throat and respiratory system).

13. What do active ingredients mean?
• Active ingredients include those
components of the product that may
undergo chemical change during the
manufacture of the drug product and
be present in the drug product in a
modified form intended to furnish the
specified activity or effect.

14. We must consider the change that has already
occurred because of chemical reaction
It's not safe to apply
pure sodium
hydroxide to your
skin, in any amount
or concentration.
Sodium hydroxide
can cause chemical
burns and severe
skin damage

15. GROUP ACTIVITY ( 5 mins)
CHEMICAL AGENT/PRODUCT NAME:
USAGE/USES ACTIVE INGREDIENT/S
Guide Questions
What is the usage of your specific chemical agents?
What are the active ingredients shown in the activity?
Why are we using chemical agents at home?

16. Alcohol Ethoxylate (AE)
• Alcohol ethoxylates (AE) are a major class of non-ionic
surfactants which are widely used in laundry detergents
and to a lesser extent in household cleaners, institutional
and industrial cleaners, cosmetics, agriculture, and in
textile, paper, oil and other process industries
• Because these compounds are surfactants, they can be
used whenever oily substances encounter water or a
surface. It can be used as detergents, wetting agents,
emulsifiers, degreasers and emollients in many lines of
commercially available products and industrial practices.

17. SURFACTANTS
• Surfactants have
a hydrophobic
(water-hating) tail
and a hydrophilic
(water-loving) head.
The hydrophobic tail
of each surfactant
surrounds soils. The
hydrophilic head is
surrounded by water

18. Sodium Alkyl Sulfates
• Sodium alkyl sulfate are members of alkyl sulfates. They
are water-soluble and can form soap bubbles.
• It can be used in detergents, dish washing liquids, shower
gels, shampoos, hair conditioners and fabric softeners. It
can also be used as fire extinguishing agent, because it is
not flammable. In the cosmetic industry it is used as an
emulsifier to mix oily and water-soluble compounds for
toothpaste or moisturizing products. It can produce
irritating vapors when heated, consisting of carbon dioxide,
carbon monoxide, sulfur dioxide and others. As all
detergents it can irritate skin and eyes. If swallowed, it will
cause nausea or vomiting.

19. Dimethiconol
• Dimethicone is a type of silicone that is often found in hair
products. Like most silicones, it coats the cuticle to make it
feel smoother. This silicone type is safe for hair, just like
the other silicones that are commonly found in haircare.
• Is dimethiconol good or bad?
• Dimethiconol is a perfectly safe and helpful skincare
ingredient. It's common in serums and gel creams to add
hydration, but also as an occlusive. Including it in a formula
usually leads to a silky, lightweight texture that oily skin
types will love.

20. Cocamidopropyl betaine
• Cocamidopropyl betaine is used as a foam booster in
shampoos. It is a medium-strength surfactant also
used in bath products like hand soaps.

21. Ethanol
• Ethanol is a natural byproduct of plant fermentation
and can be produced through the hydration of
ethylene. It mixes easily with water and many organic
compounds, and makes an effective solvent for use in
paints, lacquers and varnish, as well as personal care
and household cleaning products. Ethanol is highly
flammable and should not be used near open flames.
Ethanol inhalation can cause coughing or headaches.

22. Sodium hypochlorite
• Sodium hypochlorite also known as bleach is another
alkali disinfectant. Bleach works by oxidizing or
breaking down the molecular bonds of stains and
germs. Another useful but dangerous cleaner it also
has strong corrosive properties that may do serious
damage to the human body.
• Ammonia and bleach are a particularly dangerous
combination, creating potentially deadly gases when
mixed. Never store these two chemicals in the same
place.

23. Citric Acid
• Citric Acid is often used in shampoo formulations to
bring the pH levels down, which improves the hair's
appearance and manageability by reducing frizz. It
can also be used in rinses to help lift or fade colors
out of the hair.

24. EXIT SLIP!
