Judge a product by its label
BY Christine and Sybil
1.Work with partner. Bring at least three(3) empty containers for a common products used in your home. Examine the label carefully.
2.What is the intended use of the product?
Laundry is a type of detergent (cleaning agent) that is added for cleaning laundry, commonly mixtures of chemical compounds including alkyl benzenesulfonates, which are similar to soap but are less affected by hard water.
Sanitizers are substances that simultaneously clean and disinfect. Disinfectants are frequently used in hospitals, dental surgeries, kitchens, and bathrooms to kill infectious organisms.
Shower gel is the general term for liquid products used for cleaning the body Shower gel is an emulsion of water and detergent base (derived from petroleum), usually with added fragrance, used as a skin cleansing agent in the shower or bath. It has advantages over soap because it is less irritating to the skin, lathers better in hard water areas and does not leave a mineral residue on the skin or in the bathtub after usage.
3. What substance or substances are found in the product?
Polyoxyethylene lauryl ether
Alkyl phenol type ether
Secondary Alcohol Ethylate ; POE Secondary al-cohol ether
Sodium dodecyl benzene sulfonate
Castor alcohol sodium
4. What, if any, hazard-related information is included on the product labeling ?
5.What, if any, safety-related instructions are provided?
What did we find out?
1.As a class, share some of the names of the substances listed on the label.
SAS(Secondary Alkyl Sulfonate), FAS(Alcohol Sulfate),
essence , no phosphorus water softener and
Redisposition resistance agent
2.Which substances are familiar to you? Which substances are unfamiliar?
I am familiar to essence and unfamiliar to another three.
3.Based on the names of substances, what similarities and differences do you notice between ingredients in the products?
In washing powder, SAS and FAS has something in common, they can let the surface tension decreased significantly. And the different way is essence is used to let the washing powder smells good, but No phosphorus water softener can remove the calcium and magnesium in the water.
4.Do you notice significant differences between products that are labelled “green” and those that are not?
“Green“ is means the products we used don’t harm the environment and poison content within the country allowed . Non green products means the products will pollute the environment or bad for people‘s health.
5.What do you think happens to the substances in these products once they are used in our home?
As we all know, they are harmful to human’ s body, so if these substances are used in our home, we may get sick or even die.
6.Should people stop using products that contain potentially dangerous compounds? Defend your answer.
Many products are dangerous though but we can not live without them in our daily lives, such as fuel, radioactive material… The only thing we need to do is to develop new material to avoid dangerous accident. It is needed but now it is unrealistic.
7.Choose one compound from the list of common product used at home. Conduct research to find out about its properties and any issues related to its production, use, or disposal. Briefly report you finding to the class.
A washing powder is a surfactant or a mixture of surfactants with "cleaning properties in dilute solutions.“ These substances are usually alkyl benzenesulfonates, a family of compounds that are similar to soap but are more soluble in hard water, because the polar sulfonate (of detergents) is less likely than the polar carboxyl (of soap) to bind to calcium and other ions found in hard water. In most household contexts, the term detergent by itself refers specifically to laundry detergent or dish detergent, as opposed to hand soap or other types of cleaning agents. Detergents are commonly available as powders or concentrated solutions. Detergents, like soaps, work because they are amphiphilic: partly hydrophilic (polar) and partly hydrophobic (non-polar). Their dual nature facilitates the mixture of hydrophobic compounds (like oil and grease) with water. Because air is not hydrophilic, detergents are also foaming agents to varying degrees.
