Soymilk, derived from the whole soybean, Glycine soja, is an emulsion that contains water-soluble proteins, carbohydrates, and most of the oil from the soybean. In the context of cosmetics, soymilk is primarily known for its skin conditioning properties. It is also referred to as soybean milk or soy drink in various contexts.
The use of soymilk in cosmetics has a rich history that dates back to ancient times when soybeans were first cultivated in East Asia. The nourishing and moisturizing properties of soybeans were recognized early on, and over time, soymilk found its way into beauty regimens. Its popularity in cosmetic products has surged in recent years due to its natural origin and the growing demand for plant-based ingredients.
The process of making soymilk involves soaking soybeans in water, grinding them, and then boiling the mixture. The resulting liquid is filtered to remove the solid residue, leaving behind a smooth, creamy emulsion. This emulsion is rich in proteins, lipids, and carbohydrates, making it an excellent ingredient for skin conditioning. The proteins in soymilk help to maintain the skin’s elasticity, while the lipids provide essential moisture, and the carbohydrates offer a soothing effect.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Soymilk:
Soymilk is primarily known for its skin conditioning properties. This means it helps to maintain the skin in good condition by improving its appearance and texture. When used in cosmetic formulations, soymilk can help to soften and smooth the skin, making it feel more supple and hydrated. This is particularly beneficial for those with dry or rough skin, as the emollient properties of soymilk can provide much-needed moisture and nourishment.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Soymilk is generally considered safe for topical application in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of soymilk during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to soymilk in cosmetic products are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
In terms of comedogenicity, soymilk has a rating of 2 on a scale of 0 (totally non-comedogenic) to 5 (highly comedogenic). This means it has a low to moderate potential to clog pores. Individuals who are prone to acne, blemishes, or breakouts should take this into consideration when choosing products containing soymilk.
