What Are Hydrolyzed Soybean Proteins

Soybean is an unusually nutritious product, which was brought to Russia by our distant ancestors from China many years ago. Due to its composition, soybean is often used as an analog of meat or dairy products, as well as actively used as an additive for sports nutrition. In the cosmetic industry, it has been used relatively recently.

Soybeans are made up of 40% protein and contain large amounts of vitamin E, calcium, potassium and iron. But the greatest value of this product for cosmetology is its embryonic tissues, which are similar in composition to the extract of the animal placenta. As a result of chemical processing, hydrolyzed proteins are produced from them – cleaved protein compounds, which, thanks to the small structure, fill the voids in the hair and restore the damaged curls.

What Are The Benefits Of Hydrolyzed Soybean proteins?

Proteins penetrate deep into the skin and hair, providing a conditioning effect. They retain moisture, protecting the strands from drying out and the negative effects of environmental factors. Soybean proteins also restore the structure of brittle and brittle hair, making it stronger and more supple, giving it a healthy shine. At the same time, the curls are not weighed down and no greasy film is created on them. On the contrary, the regular use of products containing soybean proteins helps to restore the regulation of scalp hair follicles and get rid of seborrhea.

Hydrolyzed soybean proteins are often used in hair curling formulations. Due to the small size of the molecules, these substances are qualitatively fixed in the hair cavities and allow to get a restorative effect close to the use of wheat proteins or keratin.

Recent scientific research has shown that soy proteins are capable of combating hair loss. Japanese scientists have split soy protein into peptides and one of them, sometime-4, has been introduced to bald rats. After a while, the skin of the animals in the place where the preparation was administered was covered with wool. This ability of soy proteins is now actively used in the industry of shampoos and serum against alopecia.

These substances are also indispensable for the production of facial skincare products. Penetrating into the deep layers of the epidermis, soybean protein molecules smooth wrinkles, moisturize the skin, protect it from ultraviolet rays and slow down the aging process.
