Eco-toothpaste: sustainable oral hygiene School year 2009-10 Promoter and Supervisor Teacher: Gabriella Giulia Pulcini
2. AIMS Developing an active citizenship; Becoming aware of correct behaviours. COMMON SPECIFIC OBJECTIVES OF THE EXPERIENCE Using waste separation; Cutting down on consumer products and choosing eco-friendly products; Understanding labels and symbols; Identifying cause-effect relationship; Finding out eco-friendly strategies as do-it-by-yourself production
3. Sustainability Sustainability is an ideology which joins together economical, social and environmental issues. Sustainability is a focal point of present and future technology: “Sustainability is satisfying the current needs without compromising future generations possibilities to meet their needs” Commission of United Nations on Environment and its Development (1987)
4. Environmental impact “Environmental impact” is: the whole of effects, positive and negative, direct and indirect, temporary and permanent, that a particular act has on the environment, considered as a complex system of human and natural resources and their interactions.
5. Packaging Packaging is the wrapping of a product used for: • Protecting • Trasporting • Preserving • Informing and communicating • Easing its use In our houses these materials are transformed into disposing waste. Packaging is paid twice: • Buying (between 20% and 60% of total cost) • Disposing (by taxes). Types of packaging Wood 3,5% Aluminium 1,19% Steel 6,2% Multi-material 8,1% Glass 40,2% Carton 12,9% Plastic 27,7%
6. Types of packaging • PRIMARY. It is the unit sale for the consumer, for example aluminium or plastic tube of a toothpaste. • SECONDARY. It is the set of more unit sales for example carton boxes containing the toothpaste tubes. • TERTIARY. Transport packing as pallet or big boxes.
7. The choice of products and responsible consumption In choosing the right product it is necessary to pay attention, beside quality and price, also nature and dimension of packing! The choice of products should consider: 1. Without o the least packing 2. Packing made of recycled material 3. Packing made of recyclable material 4. Packing made up of an only material For example the choice of cosmetics and dentifrices should be made among those which are without wrapping.
8. The choice of products and responsible consumption The choice of products should be based on real necessity and on an appropriate estimate of product, according to the labels , symbols and logos that certify they are eco-friendly.
9. Analysis of a counter product:the toothpaste History of Toothpastes The first record of toothpaste is in 1780 and included scrubbing the teeth with a formula containing burnt bread! Most toothpastes in the 19th century came in powder form. The succulent strawberry was considered to be a "natural" solution for preventing tartar and giving fresh breath. Many early toothpastes were made with urine! They believed its ammonia content served as a cleaning agent. Fluoride was added to toothpaste in 1914 to fight tooth decay.

24. The eco-friendly hygiene It is possible to have an effective oral hygiene without fluoride, colouring agents, saccarine and other chemical elements which can be considered dangerous for our health and sustainability. The use of natural ingredients as Mint, Sage, Vera Aloe, Silica, Lime, Horse chestnut, Tea Tree Oil, Mentol, Xilitol allow to have healthy and beautiful teeth respecting nature.
25. Let’s make a homemade toothpaste - two tablespoons of liquid glycerin - two tablespoons of sodium bicarbonate - 1-2 coffeespoons of kaolin - 1 coffeespoon of fine salt (strained) - 3 drops of Lemon essential oil - 2 drops of Peppermint essential oil Mix all the ingredients together (except for essential oils) blending them well in order not to have lumps. Add the essential oils and stir well. Pour it in a bottle. Expiring date is after 30 days - room temperature.
26. Another recipe - 65 g Kaolin - 50 ml water - 1g of NaCl - 1 coffeespoon of bicarbonate - 1 drop of sage essential oil - 2 drops of tea tree Mix all the ingredients (except for essential oils), blending them well in order not to have lumps. Add the essential oils and stir well Pour it in a bottle and store in the refrigerator.
27. Comparison between commercial and home made toothpastes Chemical-physical characteristics (pH, density, smell, colour, appearance) Ingredients analysis (natural, artificial) Microbiological characteristics (UFCs present 24 hours after the opening of the product) Defining PAO (Period After Opening) Used packing analysis Environmental impact analysis
28. Conclusions SUSTAINABILITY …IS NOT ABOUT A DESTINATION …IT IS SIMPLY A DIRECTION “Life’s challenges are not supposed to paralyze you. They are supposed to help you discover who you are.” Bernice Johnson Reagon Singer, composer, scholar, and social activist
