Tea seed saponin, a glycoside compound derived from camellia seeds or tea seeds. Saponin is an excellent natural non-ionic surfactant. It is widely used as an adjuvant of pesticide, fungicide, herbicide in agriculture now. Tea saponin is an eco-friendly product that can degrade automatically with no hazardous residue left. HLB value is about 16. It has good functions of foaming, foam stabilization, emulsification, and wetting.
Dora Agri is a professional tea saponin supplier in china. Hot products are tea saponin liquid 35% and tea saponin powder 60%. We have exported to Europe and America for more than 6 years.

1. Surface tension and Critical micelle Concentration
The CMC of tea saponin is about 0.5%, and the surface tension is about 42.1 mN/m. In general, it should be slightly larger than CMC in order to fully play its role.
2. Foaming and foam stability
Configure tea saponin solutions with different mass fractions, pour into a graduated cylinder with a stopper, and turn it upside down 30 times (2s each time), put it on the table, record the foam height at the beginning and the foam height after 30 minutes, repeat 3 times ,take the average.
The Mass Fraction(%) | Foam Height(cm) | Foam Height after 30 minutes(cm) |
1.00 | 47 | 45 |
0.50 | 42 | 40 |
0.10 | 37 | 36 |
0.05 | 33 | 31 |
0.01 | 18 | 15 |

3. Compounding with pesticides
- Monosultap and tea saponin have a synergistic effect on leafhoppers and slime worms after 3: 1 mixing.
- Malathion and tea saponin have a synergistic effect on leafhoppers and aphids after 4: 1 mixing.
- Beta-cypermethrin and tea saponins have a synergistic effect on the vegetable aphid after 1: 5 mixing.
- Benzoxan and tea saponin have a synergistic effect on inhibiting the growth of cucumber mycelium after 1: 4 mixing.
- Tea saponin also has obvious synergistic effects when mixed with various insecticides such as metronidyl, nisolamide, tachylone, nicotine, tripterygium, Bt, and Tolk.
Application in Agriculture
1. Environmentally Friendly Pesticide Additives
Tea saponin can be used as environmentally friendly pesticide additives, can be widely used in the production of pesticides, fungicides, herbicides, etc., to achieve solubilization and efficiency, reduce toxicity. And used as an agrochemical adjuvant to improve the suspending rate and reduce the dosage. Tea saponin itself is also a good biopesticide, can also stimulate crop growth. Prevention of underground pests and does not cause soil pollution, which is conducive to environmental protection.
2. Clean Shrimp Pond
Tea saponin has ichthyotoxic and hemolytic effects to eliminate harmful fish and harmful insects in shrimp ponds.
Helps shrimp shed their shells earlier and promotes the growth of shrimp and crabs. Detoxifies quickly in the water and is harmless to cattle and people who may use the water. Does not leave any accumulated undesirable residue and is readily available and economical to use Because of its hemolytic effect and fish poisoning function (3ppm will produce good results), it can be made into a pond cleaner to kill unwanted fish but is harmless to shrimp (safe concentration is 20ppm).
3. Lawn Environmental Regulator
Pesticides are used extensively each year in the maintenance of golf course turf, and these pesticides can spread into the air and run off with rain or sprinkles into nearby rivers, lakes, and other waters. Pesticides can also leach into groundwater or be absorbed by crops and target organisms, which can pose a significant threat to the biological environment.
Tea saponin can kill pests and control worms alone and can improve the utilization of other pesticides. Mixing tea saponin powder with chemical pesticides can greatly improve the insecticidal effect. Tea saponin insecticide is very effective in repelling and killing snails in turf, etc., where saponins play an important role in improving its effectiveness. However, mixing tea saponin with other chemical fertilizer pesticides will be more effective in preventing and killing worms and vegetable moths.
