Green Cleaning: Ingredients whose sole purpose is to affect the odor or smell of a product and does not contribute to the cleaning efficacy of the product itself. However fragrances can be valuable to mask the malodor of some basic ingredients without which may result in occupant complaints and the use of additional products to eliminate the perception of the lack of cleanliness actually due the malodor of the cleaning product itself. Some fragrances are made from hundreds of individual compounds that are typically high in VOCs and when inhaled can cause a variety of health problems such as dizziness, nausea, and trigger asthma especially among vulnerable and sensitive populations. Furthermore, some cleaning products contain higher concentrations of fragrances compared to others. More preferable products contain fragrances that minimize impacts on health and the environment either based on the formulation of the fragrance or due to the use of lower concentrations (enough to simply mask the malodor of the basic ingredients) in the cleaning product compare to other products used for the same purpose.
