Acid Oil Soya
Acid Oil Soya is a byproduct derived from the refining of soybean oil. It is a dark-colored, free fatty acid-rich liquid containing mainly oleic and linoleic acids. Acid Oil Soya is commonly used in industrial applications such as soap making, animal feed, and as a raw material in the production of biodiesel, lubricants, and other chemicals.
African Potato Extract
African Potato Extract is derived from the plant Hypoxis hemerocallidea, a medicinal plant native to southern Africa. It is commonly used in traditional African medicine for its anti-inflammatory, antioxidant, and immune-boosting properties. The active compound in the extract is hypoxoside, which is converted in the body to rooperol, a potent antioxidant. African Potato Extract is often used as a complementary treatment for conditions like arthritis, prostate issues, and certain infections, though scientific evidence on its effectiveness is still limited.
Amprolium HCL
Amprolium Hydrochloride is a white, odorless, crystalline powder used primarily as a coccidiostat, which means it inhibits the growth of Eimeria species (protozoan parasites) responsible for coccidiosis in poultry and other animals. It works by mimicking thiamine (vitamin B1), thereby competitively inhibiting thiamine uptake by the parasite, disrupting its metabolism, and preventing its proliferation. Amprolium HCl is widely used in veterinary medicine, especially in poultry farming, and is often included in feed or drinking water. It complies with BP 2008 and USP 32 pharmacopeial standards.
Arabic Gum
Arabic Gum, also known as Gum Acacia, is a natural gum harvested from the sap of Acacia trees, primarily Acacia senegal and Acacia seyal.

It is widely used as an internal deodorant for controlling odor from flatulence and stool, especially in patients with gastrointestinal conditions or post-surgery stomas. It also serves as a mild astringent and has hemostatic properties, making it useful in wound care products. Due to its insolubility in water and stability, it is suited for oral and topical formulations.
Bromelain
Bromelain is a natural mixture of proteolytic enzymes derived primarily from the stem and fruit of the pineapple plant (Ananas comosus). It appears as a pale yellow to off-white powder with a characteristic mild odor and is water-soluble. Bromelain exhibits protease activity, breaking down proteins into peptides and amino acids, making it valuable in medical, food, and industrial applications. It is widely used as an anti-inflammatory agent, digestive aid, meat tenderizer, and in cosmetic formulations due to its enzymatic and therapeutic properties.
