Glycine soja oil is an oil derived from the wild soya bean, Glycine max or Glycine soya.

What it is used for and where

Medical and pharmaceutical

In this oil, linoleic acid is the predominant fatty acid with 51% of the overall fat content. Scientific literature agrees that linolenic acid improves circulating lipid levels and is useful in the prevention of cardiovascular diseases. 

Cosmetics

Glycine soja oil is used as an emollient in cosmetics to counteract the effects of loss of skin elasticity due to slimming processes, skin ageing, cellulite, pregnancy and others. In connective tissue, there is a decrease in protein metabolism and an increase in enzymes that lead to the breakdown of collagen and elastin. Emollients try to restore this damage.

Fragranza. Ha un ruolo decisamente importante nella formulazione di prodotti cosmetici in quanto consente di migliorare, mascherare o aggiungere profumo al prodotto finale aumentandone la commerciabilità.  Il consumatore si aspetta sempre di trovare un profumo gradevole in un prodotto cosmetico.

Skin conditioning agent. It is the mainstay of topical skin treatment by restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants.

Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss.  Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.
