Production of Air Fresheners for Mobile Toilets
The production of air fresheners for mobile toilets can be achieved through the following methods, with specific steps and principles as follows:

I. DIY Air Freshener with Floral Water
Materials: Floral water, small air freshener bottle, wick.
Steps: Pour the floral water into the small air freshener bottle, insert the wick, and place it inside the mobile toilet (such as beside the sink or on the toilet).
Principle: Floral water contains alcohol and fragrance ingredients, which diffuse the aroma through the wick and also have mosquito-repellent effects. Advantages: Simple operation and low cost. Disadvantages: The fragrance has a relatively short duration and requires regular replenishment of floral water.
II. Production with Professional Formula
Materials and Tools: 50 grams of natural plant wax (soy wax or beeswax), 15 milliliters of high-purity essential oils (a compound formula of lemongrass/tea tree/mint), 5 milliliters of slow-release regulators (isopropanol or dipropylene glycol), a heat-resistant glass jar (100ml), an electronic scale, a constant-temperature water bath, a stirring rod, and a vacuum-sealed jar.
Steps:
- Formula Selection: Adjust the formula according to the space size—use a volatile formula (25% essential oils + isopropanol) for spaces of 2-3 square meters, and an adsorptive formula (15% essential oils + plant wax base) for spaces larger than 5 square meters.
- Matrix Processing: Heat the plant wax in a water bath to 75±2℃, remove from heat and cool to 55℃, then add the essential oils and stir at 300 revolutions per minute. Next, add the slow-release agent and rapidly cool to 40℃.
- Device Assembly: Adopt a three-layer structure—activated carbon at the bottom to adsorb impurities, the mixed matrix in the middle, and a microporous ceramic sheet on top to control the evaporation rate.
Principle: Plant wax serves as a carrier to extend the release time of essential oils, the slow-release agent regulates the evaporation rate, and activated carbon purifies the air. Advantages: Long-lasting fragrance and natural ingredients. Disadvantages: The production process is relatively complex and requires professional tools.
III. DIY Air Freshener with Fabric Softener
Method 1: Drip some fabric softener onto a face towel and hang it inside the toilet.
Method 2: Directly drip the fabric softener into the toilet tank to release fragrance when flushing.
Principle: Fabric softener contains fragrance ingredients, which diffuse the aroma through water evaporation or flushing. Advantages: Convenient operation. Disadvantages: The fragrance may be too strong and requires frequent replenishment.
IV. Production of Waterless Air Fresheners
Materials: Spirit (high-purity alcohol), essential oils (for deodorization, choose ho leaf/lemongrass/spearmint; for disinfection, choose Siberian fir/grapefruit/bay leaf/cajeput), a glass bottle, and reeds.
Steps:
- Solvent Selection: Spirit is chosen for its good volatility and solubility, which can rapidly diffuse the essential oils.
- Essential Oil Blending: Add the essential oils in the order of base, middle, and top notes, with a total recommended concentration of 8%.
- Assembly: Pour the mixture of spirit and essential oils into the glass bottle, insert the reeds, and stir slightly.
Principle: Alcohol serves as a solvent to accelerate the evaporation of essential oils, and the reeds diffuse the aroma through capillary action. Advantages: No heating required and rich fragrance layers. Disadvantages: Alcohol is flammable and should be kept away from fire sources.
Precautions:
- Choose essential oils that avoid allergens and use with caution for children or pregnant women.
- Strictly control the temperature during the production with professional formulas to avoid the inactivation of essential oils.
- Regularly clean the air freshener device to prevent bacterial growth.
