Silk-Derived Ingredients

Premium Natural Silk Actives for Cosmetics, Nutrition & Functional Products

Silk-derived ingredients are a unique class of natural bioactive materials extracted from silk cocoon or silkworm pupa proteins. These ingredients contain peptides, amino acids, and fibroin proteins that offer excellent biocompatibility, skin affinity, moisturizing ability, and nutritional value.

Because of their exceptional properties, silk-based ingredients are widely used in:

• Cosmetics and personal care

• Functional foods and beverages

• Dietary supplements

• Medical nutrition

• Hair care formulations

Chibio Biotech provides a complete Silk Ingredient Portfolio, including:

• Silk Amino Acids

2. Silk Amino Acids

Introduction

Silk Amino Acids are low molecular weight amino acid mixtures obtained from hydrolyzed silk protein. Because of their extremely small molecular structure, they exhibit excellent water solubility and rapid absorption.

These ingredients are widely used in cosmetics, nutrition products, and functional beverages.

Key Characteristics

• Average molecular weight: approx. 90 Da

• Excellent water solubility

• Fast skin absorption

• Strong moisturizing and conditioning properties

Applications

Cosmetics:

• Facial serum

• Essence

• Facial masks

• Eye masks

• Creams

• Hand creams

• Shampoo and conditioner

Nutrition:

• Oral liquid

• Capsules

• Protein powder

• Functional beverages

• Energy drinks

Typical Use Levels

Application	Dosage
Daily skin care	0.5 – 2.0%
Sunscreen products	0.5 – 1.0%
Dry skin products	1.0 – 2.0%
Hair care	0.25 – 0.5%

3. Silk Peptide

Introduction

Silk Peptide is a water-soluble polypeptide derived from hydrolyzed silk fibroin protein. Compared with amino acids, peptides maintain a larger molecular structure, giving them better film-forming, conditioning, and moisturizing effects.

Key Characteristics

• Molecular weight: 500 – 30,000 Da

• Excellent skin affinity

• Good water solubility

• Smooth sensory profile

Applications

• High-end skincare formulations

• Anti-aging serums

• Moisturizing creams

• Facial masks

• Hair conditioners

• Baby skincare products

Cosmetic Functions

• Moisture retention

• Skin conditioning

• Film-forming protection

• Hair smoothing

4. Sericin Powder

Introduction

Sericin is the natural hydrophilic protein surrounding silk fibroin in the silk cocoon. It possesses strong moisture retention and protective properties, making it highly suitable for cosmetic formulations designed to support skin barrier function.

Key Characteristics

• Hydrophilic protein

• Excellent moisture retention

• Skin barrier support

• Protective film formation

Applications

• Moisturizing creams

• Skin repair products

• Baby skin care

• Sensitive skin formulations

• Shampoo and conditioner

Cosmetic Benefits

• Enhances skin hydration

• Protects the skin barrier

• Improves skin softness

• Reduces dryness

5. Silk Powder

Introduction

Silk Powder is a fibroin-based macromolecular silk protein powder produced through degumming and micronization processes.

Unlike soluble silk ingredients, silk powder functions primarily as a texture modifier and sensory enhancer in cosmetic products.

Key Characteristics

• Average molecular weight: approx. 25,000

• Fine particle structure

• Oil absorption capability

• Soft-touch texture

Applications

• Face powder

• Pressed powder

• Cleansing powder

• Makeup formulations

• Oil-control skincare products

Functional Benefits

• Smooth skin feel

• Oil absorption

• Improved cosmetic texture

• Soft-focus effect

6. Silkworm Pupa Amino Acids

Introduction

Silkworm Pupa Amino Acids are obtained from silkworm pupae through protein hydrolysis, producing a mixture of essential amino acids suitable for nutritional and functional food applications.

Compared with cocoon-based silk ingredients, this product is more suitable for health foods, nutritional supplements, and animal nutrition.

Key Characteristics

• Rich amino acid profile

• High protein nutrition

• Good digestibility

• Suitable for functional foods

Applications

• Health food products

• Oral liquids

• Capsules

• Protein powders

• Functional beverages

• Medical nutrition

• Animal feed
