Soy Protein Isolate 100 g

A Plant-Based Protein Solution for Conditioning Hair and Firming Skin Formulas

Soy Protein Isolate is a concentrated protein fraction extracted from soybeans through deep purification from fats and carbohydrates. This highly refined raw material offers strong film-forming and conditioning properties, making it a valuable ingredient in the production of skincare, hair care, and styling products, as well as formulations aimed at aging or problematic skin. The 100 g package size is well suited for home-based cosmetic making, laboratory testing, and small trial batches before scaling up to larger production runs. This ingredient belongs to the category of Hydrolyzed Proteins, which brings together plant and animal derived protein components used to build conditioning formulas.

The primary global demand for soy protein isolate actually extends well beyond cosmetics. This protein is widely used in the food industry as a functional additive that boosts the nutritional value of products, and it plays a major role in sports nutrition and meat alternative manufacturing. Within cosmetic formulations, it is valued for its ability to form a thin protective film on the hair shaft, reducing porosity, minimizing static, and leaving hair smooth without weighing it down. For skin, it functions as a hydrating and antioxidant-supporting component that helps maintain firmness and reduce visible signs of fatigue in the dermis.

In shampoos, conditioners, and hair masks, soy protein isolate should be introduced during the water phase at temperatures not exceeding 40-45 degrees Celsius to preserve the integrity of the protein molecules. Recommended usage levels range from 1 to 5 percent of the total formula weight, depending on the desired conditioning intensity. It pairs well with other protein and polysaccharide additives, such as Rice Protein Hydrolyzate, which enhances smoothness and lightweight styling, or Hydrolyzed Silk Powder, which adds an extra silky glide and softness to the finished product.

For skincare formulas targeting the face and body, soy protein isolate is frequently combined with mineral ingredients, including Hydrolyzed pearl powder, together producing formulas with a gentle smoothing and toning effect suitable for serums, creams, and masks. In household chemistry and delicate fabric care products, soy protein isolate is used as a fiber-softening component that reduces mechanical damage during washing cycles.

Store soy protein isolate in a dry area, in tightly sealed packaging, protected from direct sunlight and excess humidity, at stable room temperature without sudden fluctuations. When these storage conditions are maintained, the product retains its declared functional properties throughout the shelf life specified by the manufacturer.
