- 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.
