Oxabiol®: Natural Antioxidant Protection for Calcium Soaps in Animal Nutrition
Protect the energy value of your fats. Naturally.
More information
Calcium soaps are a strategic ingredient in modern ruminant nutrition. As a rumen-protected fat, they provide high-density energy without disturbing rumen fermentation, supporting milk yield, milk fat content, fertility and overall animal performance. However, their high content of unsaturated fatty acids also makes them highly vulnerable to oxidation during processing and storage.
When calcium soaps oxidize, fatty acids degrade, nutritional value is lost and harmful secondary compounds may be formed. This directly impacts feed quality, animal health and economic efficiency. For producers and feed manufacturers, oxidative instability means reduced product consistency, shorter shelf life and higher formulation risk.
Natural antioxidant protection is therefore not optional, it is essential.
Why tocopherols are the ideal antioxidants for calcium soaps
Tocopherols, the natural forms of Vitamin E, play a dual role in calcium soap applications. They are highly effective lipid antioxidants, capable of neutralizing free radicals and interrupting oxidation chains in fats and oils. At the same time, they deliver nutritional Vitamin E to the animal, supporting immune function, fertility and overall productivity.
Compared with synthetic antioxidants such as BHT, natural tocopherols offer key advantages:
- Higher oxidative stability in lipid-rich matrices
- No regulatory dosage limitations
- Renewable, consumer-aligned origin
- Added nutritional value for livestock
This makes tocopherols uniquely suited to protect high-fat ingredients such as calcium soaps while contributing to sustainable and high-performance animal nutrition.
At BTSA we offer Oxabiol®
At BTSA we offer Oxabiol®, a range of natural tocopherol-based antioxidants specifically developed for animal nutrition. Oxabiol® is designed to protect calcium soaps and other lipid-rich feed ingredients against oxidation, preserving fat quality, energy value and shelf life while delivering the benefits of natural Vitamin E.
Oxabiol® combines:
- High-purity natural tocopherols
- Excellent solubility in fats
- Strong resistance to thermal and oxidative stress
- Full compatibility with feed manufacturing processes
The result is a robust, natural antioxidant solution tailored to the real challenges of fat stabilization in animal feed.
Proven performance: Oxabiol® tested with RapidOxy
To demonstrate the effectiveness of Oxabiol® in calcium soap applications, BTSA evaluated its performance using the RapidOxy method, an accelerated oxidation test widely recognized in feed, food and cosmetic industries.
RapidOxy measures oxidative stability by subjecting fat samples to high oxygen pressure and elevated temperatures (up to 200 °C) inside a sealed chamber. The time required for oxygen pressure to drop indicates the resistance of the fat to oxidation, the longer the time, the better the oxidative stability.
BTSA applied this method to PFAD (Palm Fatty Acid Distillate), a common raw material used to produce calcium soaps, testing the following samples:
- PFAD without antioxidant
- PFAD + 200 ppm BHT
- PFAD + 500 ppm Oxabiol® T30
- PFAD + 1000 ppm Oxabiol® T30
- PFAD + 500 ppm Oxabiol® T50
- PFAD + 1000 ppm Oxabiol® T50
The results
Oxabiol® significantly improved the oxidative stability of PFAD compared with untreated material and even with synthetic antioxidants:
- Oxabiol® at 1000 ppm increased oxidative stability by 13.38% versus PFAD without antioxidant
- Oxabiol® Premium achieved an improvement of 24.03% at the same dosage
These results confirm that natural tocopherols from BTSA not only protect calcium soap raw materials effectively, but can match or outperform synthetic antioxidants under accelerated oxidation conditions.
What this means for calcium soap producers
By integrating Oxabiol® into calcium soap formulations, manufacturers and feed producers gain:
- More stable fat raw materials
- Reduced oxidative degradation during storage and transport
- Preserved energy value and nutritional quality
- Added Vitamin E for animal health
- A natural, regulation-friendly solution
Oxabiol® helps protect both your product and your reputation, ensuring that the energy you formulate into your calcium soaps is the energy that reaches the animal.
Move to natural antioxidant protection
Oxabiol® is more than an antioxidant. It is a natural tool to improve feed quality, animal performance and sustainability in modern ruminant nutrition.
