| Product Name | Sericin Protein, Hydrolyzed |
| CAS | 60650-88-6 / 7732-18-5 / 122-99-6 / 70445-33-9 |
| Description | Unique glycoprotein isolated from natural silk produced by the silk worm Bombyx mori. Hydrolzyed (fragmented) for better solubility and skin-penetration. Has strong affinity to keratin and forms a natural semi-occlusive, protecting anti-wrinkle film on the skin surface imparting an immediate, long lasting, smooth, silky feeling. Hydrolyzed sericin provides excellent film-forming, conditioning, and anti-wrinkle properties. It reduces significantly transepidermal water loss and skin irritation. Smoothing and moisturizing activities that persist even after washing leaving the skin or scalp silky and smooth. |

What is hydrolyzed sericin protein and where does it come from?
Hydrolyzed sericin protein is a silk-derived protein that originates from the cocoons of the Bombyx mori, or mulberry silkworm larvae. It is processed to improve its solubility and absorption, making it an advantageous ingredient for skincare and haircare products.
How does hydrolyzed sericin protein benefit the skin?
Hydrolyzed sericin protein resembles the collagen fibers found in our skin, providing a similar structure. It is a potent moisturizing agent that forms a thin, protective layer on the skin, enhancing hydration and reducing trans-epidermal water loss. The protein increases skin elasticity, rejuvenates skin cells, reduces wrinkles, and imparts a natural smoothness and glow.
Why is hydrolyzed sericin protein included in hair care formulations?
Hydrolyzed sericin is added to hair care products due to its ability to prevent and repair hair damage. It provides moisture and strengthens hair by maintaining the hair's natural keratin balance.
What is the mechanism of action for hydrolyzed sericin protein?
Hydrolyzed sericin protein acts by binding silk strands into a cocoon-like structure, enhancing wound healing and coagulation. This property helps to safeguard skin and hair against damage and environmental stressors, while also facilitating faster cellular repair and moisture retention.
Are there any side effects associated with the use of hydrolyzed sericin protein?
Hydrolyzed sericin protein is generally regarded as a safe and effective ingredient with no notable adverse side effects. Its compatibility with human skin protein structures makes it a 'superhero' ingredient in skincare.
What is the recommended usage concentration for hydrolyzed sericin protein in formulations?
The recommended usage rate for hydrolyzed sericin protein in formulations is between 2% to 5%. It should be added to the aqueous phase of emulsions, preferably at temperatures below 104 degrees Fahrenheit (40 degrees Celsius) to ensure its integrity and efficacy.
Can hydrolyzed sericin protein be used in all types of skincare products?
Yes, hydrolyzed sericin protein is versatile and can be incorporated into a variety of skincare products, including lotions, serums, and creams, to enhance hydration, elasticity, and overall skin health.
How is hydrolyzed sericin protein different from other silk proteins like fibroin?
Sericin is the outer layer of silk protein, chiefly responsible for binding silk strands, whereas fibroin resides within the silk and aids in skin cell repair and moisture regulation. Both proteins offer unique benefits, with sericin enhancing moisture retention and fibroin focusing on repair and protection.
What precautions should be taken when formulating products with hydrolyzed sericin protein?
Formulators must ensure the protein is incorporated into the product under controlled temperature conditions to maintain its benefits. It should be part of the aqueous phase and handled carefully to prevent loss of potency.
