Ectoine is a natural, highly-soluble, low-molecular-weight, zwitterionic cyclic amino acid derivative, found in several species of extremophilic microorganisms. It is a compatible solute, also called extremolyte, which serves to stabilize the physiological properties of the cells and protect them from external osmotic stress, caused by high salinity, heat, loss of water and UV irradiation.
Ectoine exerts cell-protective, anti-inflammatory and anti-allergic activity, and demonstrates a high efficacy and safety profile.

Trehalose, also known as the “sugar of life” or “resurrection sugar”, is associated with the survival of several organisms that live under extreme environmental conditions. It is a naturally occurring disaccharide comprised of two molecules of glucose. It is present in a variety of organisms such as bacteria, yeast, fungi, insects, invertebrates animals, and lower and higher plants, which synthesize it as a source of energy and use it to survive from freezing and lack of water. 

 APPLICATIONS: Trehalose is widely used in the food industry, acting as a safe preservative by inhibiting the degradation of carbohydrates, proteins, and fatty acids in foods. 
It is also used in cosmetics, functioning as a moisturizer, skin protectant and antioxidant. Trehalose is a new entry in the pharmaceutical toolbox. 
It is applied in the biopharmaceutical industry to stabilize proteins, lipids, and carbohydrates, in the preservation of labile protein drugs, and in the cryopreservation of human cells. 


We offer high-quality low endotoxin and GMO-free Trehalose dihydrate and Trehalose anhydrous, for pharmaceutical and cosmetic applications, at competitive prices.

Have you ever considered how living beings, whether plants or microorganisms, manage to survive under unfavourable external conditions? Several species of bacteria with the ability to grow in extreme environmental conditions contain ectoine.
Ectoine serves to stabilize the physiological properties of the cells and protect them from external osmotic stress, caused by high salinity, heat, loss of water and UV irradiation. Ectoine can be beneficial for the human body, in the same manner that it helps these microorganisms survive under extreme environmental conditions. This powerful ingredient is applied in dermocosmetics, in skincare products and sunscreens, as it protects the skin from the sun and provides outstanding hydration and anti-aging actions. Thanks to its lubricating effect, ectoine is also administered for the treatment of eye-disorders. It relieves irritation and inflammation, ensuring optimal lubrication. Ectoine is also used in nasal sprays to treat symptoms of respiratory impairment, induced by carbon-related lung inflammation, allergic rhinitis or asthma. 

We offer high quality synthetic ectoine, ≥98% (HPLC). 

Low biological burden: Contrary to fermentation, our synthetic ectoine has low biological burden, which makes it, readily suitable for all applications. 

Cost-effective high-volume production: We have developed and optimized our chemical process in-house for safe, lean and scalable cGMP manufacturing, providing significant economic benefits for high volume production.
