Freshener Gel is a simple gel-based air-freshening product designed to provide a continuous fragrance effect in suitable indoor applications. The formulation in the provided formula book uses fragrance, carrageenan gum, sodium benzoate and propylene glycol in a water-based system.
Freshener Gel – Product Overview
Freshener Gel can be developed as a fragranced gel for applications such as:
- Rooms
- Offices
- Shops
- Bathrooms
- Wardrobes
- Other suitable indoor spaces
The source provides one Freshener Gel formulation with a 100 kg batch size.
100 KG Freshener Gel Formula
| Raw Material | Quantity |
|---|---|
| Fragrance | 4 kg |
| Carrageenan Gum | 1 kg |
| Sodium Benzoate | 100 gm |
| Propylene Glycol | 5 kg |
| Water | 90 kg |
Total = 100.1 kg as written in the source.
The source itself lists 90 kg water together with the other quantities and does not explicitly reconcile the resulting total. Therefore, the quantities above are reproduced as provided rather than silently changing the water quantity.
Function of Each Raw Material
1. Fragrance – 4 kg
Fragrance is the primary perfume component responsible for the characteristic aroma of the finished Freshener Gel.
The fragrance type and strength can affect the final odour profile and consumer perception.
2. Carrageenan Gum – 1 kg
Carrageenan Gum is the main gel-forming/thickening material specified in the formulation.
It helps convert the liquid system into the desired gel structure.
3. Sodium Benzoate – 100 gm
Sodium Benzoate is included as a preservative component in the source formulation.
4. Propylene Glycol – 5 kg
Propylene Glycol is included as part of the formulation’s liquid system.
5. Water – 90 kg
Water acts as the main carrier/base of the formulation.
Manufacturing Process
The supplied formula book gives the following process:
Step 1 – Prepare the Water
Take the required quantity of water in a clean and suitable mixing vessel.
Step 2 – Add Carrageenan Gum
Add the Carrageenan Gum to the water and mix properly.
Step 3 – Heat
Heat the Carrageenan Gum and water mixture as specified in the source process.
Step 4 – Add Remaining Ingredients
Add the remaining chemicals to the heated mixture and mix properly.
Step 5 – Cooling
Allow the mixture to cool.
Step 6 – Gel Formation
As the product cools, it forms the Freshener Gel.
Important Manufacturing Points
The source specifically states that Carrageenan Gum should be mixed in water, heated, and then the other chemicals should be added before allowing the batch to cool and form the gel.
For production:
- Use a clean mixing vessel.
- Use good-quality Carrageenan Gum.
- Ensure the gum is properly dispersed.
- Avoid excessive aeration during mixing.
- Check the gel structure after cooling.
- Test fragrance performance before commercial production.
- Make a small trial batch before moving to large-scale production.
The formula book also advises making small batches first because chemical quality can affect the required quantities, and thickener quantities may need adjustment according to product requirements.
Finished Product Evaluation
After cooling, evaluate the finished Freshener Gel for:
Appearance
The gel should have a uniform appearance without obvious lumps or undispersed gum.
Gel Structure
Check whether the gel has sufficient body and remains stable during storage.
Fragrance
Evaluate fragrance intensity and overall odour profile.
Homogeneity
The fragrance and other ingredients should be uniformly distributed throughout the gel.
Stability
Observe the product during storage for:
- Separation
- Liquid release
- Excessive drying
- Change in fragrance
- Change in gel structure
- Colour changes
The source does not provide specific numerical QC specifications, stability periods or fragrance-release performance values, so these should be established through your own product-development testing rather than assumed.
Packaging
Suitable packaging should be selected based on the final gel consistency and intended application.
Possible formats include:
- Wide-mouth plastic containers
- Decorative gel cups
- Air-freshener jars
- Suitable PP/HDPE containers
The packaging should protect the product during storage and allow the fragrance to diffuse according to the intended product design.
Applications
Freshener Gel can be positioned for suitable indoor fragrance applications such as:
Home
- Living rooms
- Bedrooms
- Bathrooms
- Wardrobes
Commercial
- Offices
- Shops
- Reception areas
- Commercial washrooms
The final application should be validated with the selected fragrance and packaging system.
How to Improve Fragrance Performance
The supplied formula does not provide a specific fragrance-boosting system or performance-enhancer recommendation. Therefore, additional materials should not be presented as part of the original formula.
For product development, fragrance performance can be evaluated through controlled trials using different fragrance grades and concentrations while checking:
- Initial fragrance intensity
- Fragrance retention
- Gel stability
- Fragrance compatibility
- Storage stability
Common Manufacturing Problems
Gel is too weak
Possible formulation-development factors include the quality and dispersion of Carrageenan Gum. Small trial batches can be used to evaluate the required gum level.
Gel contains lumps
This can occur when the gum is not adequately dispersed before or during heating.
Fragrance performance is low
The fragrance grade, fragrance concentration and packaging system can all affect the final product performance.
Liquid separates from the gel
Check gum dispersion, heating, mixing and cooling conditions and conduct a controlled stability trial.
Product dries too quickly
Evaluate the fragrance, packaging and overall formulation under actual storage conditions.
Safety Precautions
Because this product contains fragrance and chemical ingredients:
- Wear suitable gloves and eye protection during manufacturing.
- Work in a well-ventilated area.
- Follow the SDS recommendations for individual raw materials.
- Avoid direct contact with eyes and skin.
- Keep raw materials and finished product away from children.
- Use appropriate packaging and storage conditions.
Frequently Asked Questions
1. What is Freshener Gel?
Freshener Gel is a fragranced gel product designed for indoor air-freshening applications.
