enter the path to the body | The substance can be absorbed into the body by inhalation spray, ingestion and through damaged skin |
Inhalation risk | Evaporation at 20 ° C is insignificant, but the concentration of harmful particles in the air can be quickly achieved by dispersing (the formation of fine droplets or dust in the air), especially in the case of use powder |
Effect of short-term effects | The substance irritates the eyes, the skin and the respiratory tract, may cause effects on the central nervous system, kidneys and gastrointestinal tract when taken orally, at a high dose or through damaged skin |

Therefore, contact of the child with concentrated solutions, especially with pure brown, should be deleted. Hit drills inside - when ingested or inhaled - is life-threatening.
natural ingredients
