• Cleaning materials remove dirt by using various chemical processes such as acids, bases, chelants, and surfactants.
• Ordinary soaps can be used to clean toilet bowls and sinks.
• Muriatic acid works better in getting rid of heavy dirt due to its corrosive properties.
• Inspect the ingredients list.
• The ingredients section lists the substances that are present in the product.
• The first aid statement provides what should be done in the event of an accident or whom to contact for medical treatment.
• The net contents statement provides the weight or volume of the product as well as the number of uses the product can provide.
• Common information in the product labels includes learning how to read household product labels, looking for warning signs, inspecting if the product is flammable, and keeping track of the expiration date.
• Labels are piece of coating materials around the container or product that contain the information or symbols regarding the product.
• Look for warning signs, such as “Poison,” “Warning,” or “Danger.” These signs indicate toxic substances are part of the ingredients.
• For a product that requires special care and handling, “Keep out of the reach of children” is usually indicated.
• Be aware of the toxic substances that may be found in the product you want to buy, such as poisonous heavy metals, hydroquinone, phthalates, and nitrosamines.
• Keep track of the expiration date.
• The precautionary statements detail how to prevent accidents or misuse of the product.
• The product must also be used in an adequately ventilated room.
• Usage instructions describe how to properly use the product for safest and best results.
• Look for statements declaring if the product is “flammable” or “combustible.” These products must be kept away from flame or heat sources.
• Products labeled “Toxic when inhaled” or “lungs and skin irritant” must be used with proper protection such as gloves and mask.
• Marketing claims include key benefits of using the products.
• The manufacturer’s contact information discloses the name, address, and phone number of the manufacturer.
• Dyes give or add color to the product because of the absorption of visible light at a certain wavelength.
• Surfactants act by diffusing in the water and adsorbing between two interfaces like air and water or oil and water.
• Alcohol is an organic compound that contains a hydroxyl functional group (–OH) attached to carbon.
• Essential oils are naturally extracted fragrant oils from plant or animal sources.
• Pigments give or add color to the product because of the absorption of visible light at a certain wavelength.
• Product labels are important in providing information on the product's origin manufacturer, shelf-life, utilization, and even disposal procedures.
• Alcohols are often added to personal care products mixed with denaturing agents or other additives to improve the smell.
• An active ingredient pertains to the substance that is mainly responsible for the chemical property of the product.
• Surfactants are substances that hold the oils and dirt in suspension.
• Additives are substances added in small quantities to improve the quality or preserve the product.
• Acids are substances with pH lower than 7, and when used in cleaning products, they help break down difficult stains, such as rust or mineral salts.
• Bases are substances with pH greater than 7, and products with basic active ingredients are useful in removing fatty and oily soils from surfaces.
• Surfactants are amphiphilic organic compounds with both hydrophobic tail and hydrophilic head that are partially water-insoluble and soluble components.
• Essential oils are naturally extracted fragrant oils from plant or animal sources, which are concentrated hydrophobic volatile aromatic compounds.
• Chelants or chelating agents are organic compounds that form a bond with ions or molecules with metal ions.
• Labels are piece of coating materials around the container or product that contain the information or symbols regarding the product.
• Most of the time, labels come as information printed directly on the packaging of the material.
