Formaldehyde has been used for a long time and was originally used to make products durable. According to the Federal Environment Agency, the substance was named “can” in June 2014 due to new findings cancer generate "classified.

Fabrics that cancer cause or increase the incidence of cancer are classified as carcinogenic. As reported by the Federal Environment Agency, rats that repeatedly inhaled high concentrations of formaldehyde have developed tumors in the nasal cavity in the course of their lives.

Hazardous substances found in aloe vera gel: Can cause cancer

However, this does not apply to formaldehyde releasers. Here formaldehyde is only contained in bound form and is only released over time. Formaldehyde release agents are still permitted as preservatives. However, the spin-offs are not in any of the two products test on the list of ingredients.

Dangerous fragrance found in aloe vera gel in test: reproduction can be damaged

The source of the formaldehyde remains unclear. But that's not all: in one of the two Aloe vera gels it contains questionable fragrances. On the one hand, the synthetic fragrance Lilial. This one has to Eco test proven to be harmful to reproduction in an animal experiment.

Aloe vera gel at Öko-Test: Misleading product description on various products

Almost all providers in the test advertise the aloe vera content in their products. However, it is loud Eco test misleading to consumers. For example, the gel of the dm own brand “Balea” costs 90 percent Aloe vera 1.95 euros (200 milliliters). The gel of the “Santaverde” brand, on the other hand, costs 37.98 euros for what appears to be the same concentration and quantity.

On the other hand, “Jean & Len” advertises their product with a 100 percent aloe vera concentration. On the list of ingredients, however, the active ingredient is only in sixth position. This can be related to processing, among other things.

The “Santaverde” brand is one of the few manufacturers in the test, which process the pulp of the aloe vera plant into a not-from-concentrate juice and mix it into the gel. Because the juice has yet to be preserved, the company cannot increase the concentration.

Aloe vera gel at Öko-Test: Powder extract is often used

Manufacturer of the products in test often use a powder concentrate. To do this, the juice from the pulp of the plant is heated in several steps and then freeze- or spray-dried. This is easier to process and carries fewer risks when it comes to preserving the aloe vera leaves.

Öko-Test: declaration of aloe vera gel unreliable

The labels on the article packaging in test customers cannot rely on. Half of the manufacturers advertise the juice of the plant: “Aloe Barbadensis Leaf Juice”. When asked, they gave Eco test indicate that they are using powder extract.

Overall, aloe vera gels are particularly suitable for travel. They cool light sunburn and soothe mosquito bites. A high concentration does not necessarily mean a high density of active substances. That depends above all on the quality of the raw materials.

Cancer from aloe vera: do not process the leaves yourself
