Personal Care Products Module: Key Ingredients and Emerging Technologies
- 13. How Do We Make Informed Decisions? A new shampoo uses 'NANO' directly as its brand. Image: Courtesy imageshack.usThe shampoo, claims to contain titanium dioxide (TiO 2 ) nanoparticles, which could penetrate more effectively into the hair and, thanks to its photocatalytic oxidation characteristics, oxidize the harmful residues after hair perming. Would you buy this shampoo?

- Key message – use of nanotechnologies not necessarily new – but we are learning how to use them more effectively and more safely. How do we make these decisions? More info at…. http://www.abc.net.au/science/articles/2006/10/02/1751084.htm
- An article published in the Age newspaper – http://www.theage.com.au/news/national/women-rush-tiny-tubs-of-rolledgold-cream/2007/05/05/1177788470691.html “ Women rush tiny tubs of rolled-gold cream” -Natasha Hughes May 6, 2007 should provoke some interesting discussion- Is there a psychological aspect to this? Does the cream really work? Why is there such a high demand for high-end face creams? Who are the products aimed at? What is an "uber luxury shopper"? Who would pay $3500 for a "super serum" which lasts for 21 days? http:// www.theage.com.au/news/national/women-rush-tiny-tubs-of-rolledgold-cream/2007/05/05/1177788470691.html (image)
- This slide should provoke some good discussion- Are all consumer products useful? Are we tricked into buying products we don’t need? Is it ignorance and lack of knowledge of what is in the product? How do we become more discerning buyers (consumers)? How is NT going to affect the cosmetic and personal care industry? A new food or beauty product is launched every three and a half minutes . (get students to calculate how many products are launched in a day, in a week, in a year. Experts predict that future products will make us smarter and younger. (what products do they have in mind?)
- On what basis do you choose a shampoo? The media tells us that the shampoo we use will change aspects of our life. It makes us charming and sophisticated… students should be encouraged to find shampoo labels and list all the claims that are made eg Can a shampoo repair, restructure, or nourish damaged hair? When we know that hair is dead and it can not be repaired. Can shampoo really prevent your color from fading? Do volumizing shampoos really work? What does this mean? Ask students to give a list of properties they think a shampoo should have. Eg It must feel thick or creamy in the hands, and must produce a nice feeling lather. Should smell nice, and not be too expensive. What sells a shampoo? Herbal extracts, amino acids from exotic proteins such as silk , nano particles What is the main purpose of a shampoo? T he prime purpose of a shampoo is to clean the hair, however if the cleaning is over done the protective oils in the hair are stripped out.
- Is the product useful? Where is the value?
- A discussion should center on “What information would you need to know before you would consider Paying $960 or $10 for a cream? This should lead to reading labels and having an understanding of basic ingredients
- Refer to http://www.science.org.au/nova/083/083print.htm and the data you collected from activity 1and 2 to answer these questions.
- Reading labels has given an insight into what products contain. Now lets make our own product
- What about nanoparticles in cosmetics? Is it safe, or more effective?.... Need to provide an explanation as to what this means, and what the current debates include.
- Research nano safety issues An example article for students to research for http://prismwebcastnews.com/2008/02/16/2101/
- How do we make informed decisions? A discussion should center on “What information would you need to know before you would consider buying this shampoo which uses 'NANO' directly as its brand and claims to contain titanium dioxide (TiO 2 ) nanoparticles, which could penetrate more effectively into the hair and, thanks to its photo catalytic oxidation characteristics, oxidize the harmful residues after hair perming . For blog about the nano shampoo: http://andrewofftheroad.blogspot.com/2006/10/new-shampoo-movement-toward-nano.html Image source: Imageshack.us http://img331.imageshack.us/my.php?image=nanoshampoosmallei7.jpg Need to tie this back to the scientific uncertainties. There is a lack of data to say such products are safe or indeed unsafe
- How do we make informed decisions when confronted with such information? What information would you need to know before you decided to buy this cream? In Australia, this product would be considered to be a therapeutic good and not a cosmetic (this is an important legal distinction)
- http://www.crownlaboratories.com/bluelizard In Australia, this product would be considered to be a therapeutic good and not a cosmetic (this is an important legal distinction) Again, need to note the divergent scientific views here, and the lack of data here. /
- The nanotechnology of making the ZnO transparent is a good reason for considering this nano product Could watch clip from CSIRO abut Australian made nano sunscreen http://www.csiro.au/multimedia/ppf33.html
- Research or discussion questions
- 1 What is a cosmetic? Cosmetic and toiletry products are preparations which make contact with any external part of the body, including the mouth and the teeth. They may alter the odours of the body,, change the appearance of the body, cleanse the body, maintain it in good condition, may perfume it or protect it. 2 What is the difference between cosmetic and therapeutic? Products that claim to ‘modify a bodily process or prevent, diagnose, cure or alleviate any disease, ailment or defect’ are called therapeutics. eg shampoos and deodorants are cosmetics, while anti-dandruff shampoos and antiperspirants are considered to be therapeutics. 3 What general ingredients do cosmetics contain? Most cosmetics contain a combination of at least some of the following ingredients: water, emulsifier, preservative, thickener, colour, fragrance , pH stabilisers. 4 What is an active ingredient? Produces the desired effect for giving the product its main characteristic. The active ingredient is not necessarily the most common ingredient in a product. 5 What is the main active ingredient in a shampoo? A detergent, a class of surfactants known as straight-chain alkyl benzene sulfonates. An example is ammonium lauryl sulfate, or its sodium relative, or the slightly larger related molecule ammonium lauryl ether sulfate, sometimes abbreviated as ammonium laureth sulfate. 6 What are the main ingredients in a conditioner? 7 What are the main ingredients in a basic hair cream? 8 What are the main ingredients in a sunscreen? 9 What role can nano play Covered previously
