Hydrogenated lecithin is the hydrogenated form of Lecithin i.e. a lecithin with added hydrogen, a natural but chemically transformed product also called alpha-phosphatidylcholine which is very complex as it is composed of choline, fatty acids, glycerol, phospholipids, amphiphilic lipids.

It appears as a white powder

A cosa serve e dove si usa

Phospholipids are the main constituent and can be extracted from both vegetable fats and eggs. The fatty acids used to obtain hydrogenated lecithin include palmitic acid, oleic acid and stearic acid. The function of phospholipids, which are found in animal and plant cell membranes, is the proper maintenance of vital organs in the human body: liver, brain, etc.

Food

The food industry uses soya lecithin and sunflower lecithin as lubricants, antioxidants and for their peculiarity of protecting and preserving the fragrance of ingredients.

Medical

The application of lecithin as an antiviral nasal spray (1) and for the treatment of allergic rhinitis has been studied in medical medicine. Furthermore, lecithin liposomes have proven effective for ENT disorders (2).

Cosmetics

In cosmetic products, lecithin in hydrogenated, biodegradable form performs the dual function of conditioning agent and surfactant (removes dirt particles) emulsifier. Minor functions such as antioxidant and dispersing agent. Lecithin has a strong affinity for mucous membranes and skin, strong hydrophilicity and moisturising properties.

Other uses

• Feed additive
• Ribonucleoprotein carrier
