Air freshener production generally involves mixing fragrance compounds with solvents and then incorporating them into a dispersal system, like aerosols, gels, or solids.
Here's a breakdown of the process:
1. Fragrance Formulation
- Selection of Fragrance Oils: Manufacturers select synthetic fragrance elements. These often include aldehydes, alcohols, and ketones, among others. The specific combination determines the air freshener's scent.
- Mixing: The selected fragrance oils are carefully blended to achieve the desired scent profile.
- Concentration Adjustment: The fragrance concentrate is adjusted to the appropriate level for the final product, taking into account the dispersal method (aerosol, gel, etc.)
2. Base Preparation
The type of base depends on the form of the air freshener:
- Aerosol Air Fresheners: The fragrance concentrate is mixed with a solvent (like alcohol or water) and a propellant (like butane or propane) under pressure.
- Gel Air Fresheners: The fragrance concentrate is mixed with water and a gelling agent (e.g., polymers, seaweed extracts). The gelling agent solidifies the mixture into a gel, which slowly releases the fragrance into the air. The gelling materials can be organic or inorganic.
- Solid Air Fresheners: The fragrance concentrate is mixed with a solid carrier material, such as a powder or a porous material that absorbs and releases the scent.
- Liquid Wick Air Fresheners: The fragrance concentrate is mixed with a solvent and then drawn up by a wick to be dispersed into the air.
3. Manufacturing & Packaging
- Aerosol Filling: For aerosol air fresheners, the mixture is filled into aerosol cans, which are then sealed and pressurized.
- Gel Molding: For gel air fresheners, the liquid mixture is poured into molds and allowed to solidify.
- Packaging: The final product is packaged, labeled, and prepared for distribution. This includes placing the gel air fresheners in containers, attaching wicks to liquid wick air fresheners, and boxing up the aerosol cans.
In summary, air freshener production combines carefully crafted fragrance formulations with various dispersal methods, resulting in products designed to release pleasant scents into the air.
