Lecithin is primarily used in the food industry for its nutritional qualities. Indeed, it is present in the majority of processed foods, notably chocolate, spreadable paste, creams, ice creams, sauces, desserts, certain biscuits, or industrial sliced bread.
In the cosmetology industry, this ingredient is valued for its role as an emulsifying agent. Emulsifiers, also known as surfactants or surface agents, are ingredients that form an interfacial film around water droplets to stabilise the emulsion over time.
Lecithin also possesses emollient properties that soften and smooth the skin. Indeed, it contains active ingredients capable of relaxing and softening skin tissues by nourishing the cells. Moreover, by utilising this ingredient in skincare, it is entirely possible to benefit from its ability to neutralise the electrical charge on the skin's surface. It is worth noting that lecithin is present in approximately 5.21% of beauty treatments, including eyebrow pencils, eye pencils, kohls, anti-ageing face creams, anti-cellulite oils, and slimming treatments.
