Many wonder: “At last, what is the difference between common and ecological laundry…?” Differences exist and, to make the best choice, it is recommended to analyse every aspect: there are pros and cons, the trick is to figure out which aspect is really a “pro” and which is a “con”, according to one’s point of view.
Let us see Bensos’ opinion:
|Optical brighteners and blue dyes
||Bright fluorescent whitening, stains covering||Brightening and covering go disappearing, replaced by a diffuse yellowing over time; optical brighteners are not biodegradable; in addition they are long-term toxic. Blue dyes are a kind of textile dyes, which may show long-term toxicity and cause allergies.|
||Particularly efficient against some stains||They are strong allergens. The safety of the most common enzyme used in detergency (a protease) is unclear and questionable.|
||Laundry perfumes strongly and for a long time||Common products fragrances are studied and intended to be persistent; often they contain allergens. Mainstream ecological products contain essential oils, showing long-term toxicities.|
||Present in powder detergents and additives||Effectiveness is strongly reduced by other ingredients, which act as “interfering agents”. Some products yet show sodium perborate as an ingredient, but it is repro-toxic against mammals.|
||Good efficacy, since 2005 only easily biodegradable ones are allowed (Reg 648/2004/CE)||Many of them are highly toxic for aquatic organisms. Some show concerning long-term toxicities.|
||They lower washing water hardness, enhancing detergent efficacy||Generally not biodegradable. Many of them show concerning long-term toxicities.|
||–||Generally not biodegradable. Many of them show concerning long-term toxicities.|
||They provide conservation, protecting the product from microbes attacks.||Many of them are not biodegradable. Most show concerning long-term toxicities. Some are strong allergens.|
The presence of interfering agents into non-ecological bleaching powder mixtures was revealed during an interesting investigation, carried out by a Padua University near-graduate student, under the direction of Prof. M. Carraro together with Dr.ssa S. Palladini. Interfering agents lead to a marked decrease of efficacy, compared to pure sodium percarbonate.
Here are Bensos’ ecological laundry detergents pros and cons:
|Bensos’ ecological products||PROs||CONs|
|Optical brighteners and blue dyes
||Missing; they are replaced by chemical bleach||Whitening is not so bright, some stains must be pre-treated.|
||Missing, as they are strong allergens||Some particular stains may be difficult to be removed.|
||Missing, to be added separately (hypoallergenic fragrance)||The perfume, intended not to be persistent, disappears after few hours.|
||Perfectly efficient, as interfering agents are totally missing.||–|
||Good efficacy, no long-term toxicity. Since 2005 only easily biodegradable ones are allowed (Reg 648/2004/CE).||–|
||They lower washing water hardness, enhancing detergent efficacy. They are easily biodegradable and non-toxic.||–|
||They provide conservation, protecting the product from microbes attacks. They are easily biodegradable and non-toxic.||They are dosed with the aim to preserve only the concentrated product, they do not work if the product is diluted and then stored for many days.|
Bensos makes only very ecological products, with neither allergens nor dyes, nor long-term toxic substances, to care for the consumers’ and Bensos’ workers’ health.
