FALSE. Jean-Marc Giroux, Pharm.D. and president of Cosmed (the association of cosmetics SMEs), explains that micro-droplets from atmospheric sprays—those without pressure or propellant gas—evaporate in seconds without dispersing particles. Brands like Puressentiel, Florame, and Naturactive exemplify this safe diffusion. Avoid confusing them with propellant-based aerosols, such as certain spray paints, which can suspend fine particles in the air that may enter the respiratory tract.
FALSE. Volatile organic compounds (VOCs) from natural sources are vital for plant life and pollination, giving flowers and fruits their scents. Synthetic VOCs, however, stem from paints, varnishes, solvents, and glues. High-quality essential oils contain purely natural VOCs. As Giroux notes, it's toxically inaccurate to equate a flower's fragrance with harmful chemical fumes.
FALSE. While not for daily use, bleach is a potent disinfectant, per Dr. Isabella Annesi-Maesano, research director at Inserm. It's ideal for contagious illness outbreaks or mold removal—a key indoor pollutant source. Due to its irritancy, always use it with windows wide open.
TRUE. Limonene, found in citrus essential oils and released when peeling an orange, even replaces solvents in eco-paints. Yet it's often labeled allergenic. Giroux clarifies it's minimally allergenic until oxidized by air exposure (per a 2009 University of Gothenburg study). The same applies to linalool and geraniol. Cosmetics makers mitigate this with opaque, air-minimized packaging to preserve efficacy.
FALSE. Prof. Antoine Magnan, pulmonologist, says no need for chemical arsenals against dust mites. For most, weekly 60°C sheet washes suffice. Allergics should choose tight-weave mattress covers that block mites, as recommended by the French Association for Allergy Prevention.
FALSE. Magnan notes that undiagnosed asthmatics might have symptoms triggered, and asthmatics often react to scents generally—emphasizing ventilation. But healthy, non-allergic people won't develop asthma just from passing through an essential oil-scented room.
FALSE. Routine cleaning is vital if dosages are followed. Skip aggressive antibacterials, advises Magnan of Nantes University Hospital. Wiping out 99.9% of germs disrupts beneficial bacteria and risks fostering antibiotic-resistant strains harmful to health.
FALSE. Strict regulations govern sales, mandating safe ingredients, formulas, and labeling. Use as directed for safety. Allergics or asthmatics: minimize products, favor unscented options like baking soda or black soap, or Ecolabel/Ecocert-certified ones that are less irritating.
FALSE. Despite hype, Prof. Damien Cuny of Lille Nord University, a longtime indoor air expert, finds their air-purifying capacity insufficient for homes.
Dr. Isabella Annesi-Maesano, Inserm's Director of Research in Epidemiology of Allergic and Respiratory Diseases, defines it as degraded indoor air from tobacco smoke, cooking/heating combustion, fireplaces, furniture glues/solvents, wall mold, dust mites, and infiltrating outdoor traffic pollution. Enclosed spaces amplify health risks.
Interior environment advisors Martine Ott and Romain Habeau stress source control: avoid tobacco, excess humidity, and synthetic fragrances. Ensure airflow via room vents (e.g., bedroom window strips) and bathroom/kitchen exhausts. Ventilate daily (morning/evening, 15 minutes) and select A+-labeled paints/varnishes for lower VOC emissions.
