Bionsen

How ethical is Bionsen?

Bionsen is a natural deodorant brand which has achieved The GOOD Shopping Guide’s ethical benchmark on our Ethical Deodorant Ratings Table. With a score of 69 out of 100, Bionsen meets the benchmark threshold, though consumers should be aware that this represents a narrow margin above the threshold and that stronger alternatives exist within the sector.

Bionsen has not yet received The GOOD Shopping Guide’s Ethical Accreditation, an editorial endorsement awarded to brands which achieve a high ethical score across our multi-criteria assessment. Receiving this endorsement would strengthen the brand’s standing as a recognised ethical choice for consumers in the deodorant sector.

What does Bionsen do?

Bionsen is a brand of Coswell SPA, an Italian family-run company founded in 1961 and headquartered near Bologna. Bionsen produces a range of mineral-based deodorants using a Thermal Salt Complex of zinc, copper, manganese, and calcium, inspired by Japanese thermal springs. Products are aluminium-free, silicone-free, paraben-free, and dermatologically tested for sensitive skin, and are available in roll-on, spray, and stick formats.

Why does Bionsen perform well ethically?

Bionsen achieves good ratings across seven of the eleven criteria assessed by The GOOD Shopping Guide. The brand receives good ratings for environmental reporting, genetic modification, and fossil fuels. Bionsen receives good ratings for armaments, irresponsible marketing, and political donations, and has no documented public record criticisms. These ratings reflect solid ethical conduct across governance and environmental criteria.

What could improve Bionsen’s ethical positioning?

Bionsen’s below-threshold performance across several criteria presents meaningful opportunities for improvement. The brand receives a poor rating for vegetarian and vegan verification. While Bionsen markets its products as vegan and cruelty-free, the absence of formal independent vegan verification means these claims have not been assessed to the standard required for a good rating. Pursuing recognised vegan verification would address this gap and provide consumers with independent assurance of the brand’s vegan credentials.

Bionsen also receives a poor rating for organic ingredients. The brand’s mineral-based formula, while free from aluminium, silicones, and parabens, does not meet certified organic standards. Pursuing organic certification for its formulations would strengthen Bionsen’s environmental credentials and bring this rating in line with the stronger performance demonstrated across other criteria.

The animal welfare rating is acceptable rather than good, indicating room for improvement in formal animal welfare commitments and certification.

Obtaining The GOOD Shopping Guide’s Ethical Accreditation would provide editorial recognition of Bionsen’s ethical standards. Given that the brand’s score sits narrowly above the benchmark, addressing the vegan verification and organic gaps in particular would have a meaningful impact on its overall ethical standing.
