The products we use every day to wash, take care of our body, guarantee our hygiene or protect us from mosquitoes, have a direct impact on the environment. During an itinerant or sedentary stay in nature, it is important to reduce this impact as much as possible, and even more so in remote and / or sensitive natural environments because these have hitherto been protected from chemical inputs and serve as a refuge for species elsewhere subjected to human pressure.
Another essential factor in nature, the waste are not treated as is usually the case in cities (this is far from the case also in many developing countries). Products applied to the skin (soap, cream, mosquito repellent, etc.) "will sooner or later slip into the earth or the river, during the shower or carried away by sweat. Ingested chemicals (water purification tablets, pills, etc.) will also be released from the body after passing through the body.
We do not seek in this article to favor one product or brand over another, but all products are not equal in terms of impact on nature. As we are directly concerned by this impact during our expeditions and our ecovolunteer missions in the field, but also as manager ofProtected Area of Makay in Madagascar, we choose here to make the results of our research public and to include the names of brands and products to help you navigate them.
Les concepteurs de produits pour le soin du corps regorgent d’inventivité pour concevoir des produits toujours plus vendeurs : cela se traduit en terme d’ingrédients par des tensio-actifs, colorants, microbilles de plastiques, nanoparticules, parabènes, phtalates etc. Creuser le sujet peut vite devenir effrayant ! Les critères auxquels nous prêtons attention lors du choix d’un produit sont les suivants : respect de l’environnement (rejet dans l’environnement), respect de la santé de l’utilisateur, et respect de la vie animale (cruelty-free, non testé sur des animaux, voire encore végan/sans composant d’origine animale). Il pourra être ajouté le cas échéant le respect des producteurs (commerce équitable). Il n’est pas toujours facile de trouver un produit qui remplisse tout ces critères, mais certaines marques font de leur mieux.
Pour faire un raccourci, moins un produit contient d’ingrédients, moins il a de chances de contenir des composés néfastes pour l’environnement. Ceci dit, il faut souvent regarder dans le détail, ce qui est laborieux. La certification biologique d’un produit est la plupart du temps quasi indispensable, mais il est intéressant de noter que cela ne suffit pas. En effet, biologique n’implique pas nécessairement biodégrable, ni sans impact sur le milieu. Par ailleurs, la certification biologique sur les cosmétiques porte souvent sur un pourcentage du produit, et non pas sur sa totalité.
Whatever product is brought in, the best is always to use as little as possible and as rarely as possible. Even an environmentally friendly product leads to the introduction of a foreign component into an environment where it is not present.
Solid or liquid?
A product in liquid form - shower gel, shampoo, etc. - often (always?) Contains preservatives which are intended to block the bacterial development favored by the liquid medium.
Soap, shampoo and toothpaste
Savon - The most natural soaps today - and since 3500 years - are the Marseille soap and Aleppo, composed only of olive oil (and oil of bay laurel for Aleppo soap). To know that these names are not protected appellations, their composition and origin is not guaranteed. So check case by case. The easiest way is to buy them organic shop because 'soaps from Marseille "supermarkets are often unsavory.
These soaps can also be used shampoo (depending on hair each) and washing machine. Some use for dishes and as toothpaste. Versatile, so light to the bag.
Shampooing - There are more and more solid shampoos today. Compact and lightweight, these are ideal for remote areas. Some brands are particularly committed to the protection of animals (such as LUSH, but, except recent change, these are not organic). Soap can also be a great substitute for shampoo, especially during the few weeks you will be in the wild.
Dentifrice - Solid toothpaste available on Lamazuna.
Natural low-cost option: baking soda / green clay.
Sunscreen is a real present ecological problem, with 25 000 tonnes discharged into the oceans each year. Its impact on marine natural environments is considerable, especially on coral reefs, which can kill within 48 hours after exposure to a toxic sunscreen. The best option currently seems to be the EQ ethical brand, We recommend.
There are probably other options, especially for sensitive skin. Please note that even some organic sunscreens and / or mineral may contain harmful components (des nanoparticules notamment, voir ci-dessous) : la composition est donc toujours à vérifier. Le mieux étant de n’en mettre que si ou quand nécessaire, d’avoir des vêtements couvrants, etc.
Identifier une crème solaire à moindre impact environnemental
- Les crèmes à filtre chimique sont toujours toxiques, à bannir donc. Elle sont également de plus en plus interdites, comme aux Palaos, à Hawaï, ou au Mexique.
- The following components are strictly avoided because of their toxicity even in small doses for corals: Oxybenzone, Octinoxate, Octocrylene, PABA (Aminobenzoic Acid) , Enzacamene, Octisalate, Homosalate, Avobenzone.
- Sunscreens mineral filter (oxide of zinc, titanium dioxide), however are not considered toxic if they do not contain nanoparticles ( 'NANO' necessarily mentioned in the product composition).
- If the nanoparticles are permanently banish, there is no scientific consensus on the non-toxicity of zinc oxide (excluding nanoparticles), which is considered a good sunscreen. That may change with the evolution of the research.
- These marks or some of their products are probably interesting: alga Maris ; Wash (ambiguous on nanoparticles); Avène Thermal Spring Water (some products contain nanoparticles).
- Read more about Reporterre how tan green? and Glamconscious: ecological ethics sunscreen which also recommends the EQ and UVBIO brands.
- Recommended brands in the United States: Raw Elements, All Good and Avasol.
Mosquito repellent without DEET is best for nature. However, many mosquito 'natural' insuffisemment prove effective in the tropics. Marks Florame and Puressentiel commercialize Special repellents tropics and infested, and 100% natural.
Treatment of drinking water
It is often best to simply boil water suffisemment long (about ten minutes). To break free of this constraint, we recommend using a filter (like Katadyn / Care Plus Sawyer) that can make drinking water immediately.
In fact, you should know that purification tablets (Micropur or hydroclonazone type) are released into the natural environment by the body and could, according to certain sources, contribute to its pollution. As a precautionary principle, we recommend that they only be used in exceptional ways.
Rules - It is best to use a menstrual cup (type Mooncup, here an here small manual). Otherwise, towels / biodegradable pads and dirt free for the body (in Biocoop, for example). The bio reusable cotton towels are possible, but the conditions for washing are not always adequate.
Urinate - The piss-standing solves the lack of privacy that can sometimes exist in some places.
Pill - Finally, although it is not always possible to change the method of contraception for a short stay in a natural environment, we must be aware that the pill also has an impact on natural ecosystems. This impact is reflected in particular by a feminization of living which reached worrying proportions in some lakes.
Wash synthetic clothes
When washing synthetic clothes (fleece, breathable T-shirts, etc.), mechanical action frees many plastic microfibres in water, pollution filters washing machines and water treatment stations can remember. A fortiori, in the case of washing clothes directly into streams of a natural area, plastic microfibres (1 to 2g per wash) are emitted directly into the medium and may then enter at the bottom in the chain food. A laundry bag that holds the fibers during washing is ideal. Available here and is.

Finally, these precautions are essential in natural environments, but it is good to know that these principles also apply at home in town or country, to reduce our footprint on our environment, wherever we may be.
