General Description

L-Cysteine is a naturally occurring amino acid widely used in the cosmetic, pharmaceutical, and food industries. Known for its powerful antioxidant and skin-repairing properties, L-Cysteine plays a crucial role in skin brightening, hair strengthening, and anti-aging formulations. It is available for bulk purchase, wholesale supply, and private label manufacturing, making it a popular ingredient among cosmetic manufacturers.

Uses in the Cosmetics Industry

L-Cysteine is a key ingredient in many personal care and beauty products, including:
✔ Skin Lightening Creams & Serums – Reduces melanin production, helping to brighten skin tone and fade dark spots.
✔ Anti-Aging Products – Supports collagen production, improving skin elasticity and reducing fine lines.
✔ Hair Care Products – Strengthens hair strands, promotes growth, and enhances shine.
✔ Nail Treatments – Helps fortify brittle nails, reducing breakage and splitting.
✔ Professional Dermatological Formulations – Used in advanced skincare treatments for pigmentation control.

⚠ Skin Sensitivity – May cause irritation or allergic reactions in some individuals.
⚠ Strong Odor – Has a sulfur-like smell that may require masking in formulations.
⚠ Oxidation Sensitivity – Can degrade if not stored properly, affecting its efficacy.

CAS Number: 52-90-4

INCI: L-Cysteine HCL

Composition: L-Cysteine HCL is an amino acid composed of a thiol (-SH) group attached to the side chain of the amino acid cysteine. It is one of the building blocks of proteins and peptides.

Purity Grade: No purity grade applicable

Appearance: L-Cysteine HCL typically appears as a white to off-white crystalline powder or colorless crystals.

Solubility: L-Cysteine HCL is sparingly soluble in water but more soluble in alkaline solutions. It is also soluble in dilute mineral acids and alkalis.

Preservation: L-Cysteine HCL should be stored in a cool, dry place away from heat and moisture to prevent degradation. It should also be protected from exposure to air and light.

Storage: Store in a closed container at a dry place at room temperature

Raw Material Source: L-Cysteine HCL can be obtained from various sources, including animal hair (such as poultry feathers), bacterial fermentation, or chemical synthesis from precursor molecules.

Manufacture: L-Cysteine HCL can be manufactured through various methods. One common method involves the hydrolysis of keratin-containing materials, such as poultry feathers or human hair, followed by purification to isolate L-Cysteine HCL. Another method involves microbial fermentation using certain bacteria or yeast strains capable of producing L-Cysteine HCL.

Animal Testing: Not animal tested

GMO: GMO-free (does not contain plant-derived components)

Vegan: Does not contain animal-derived components

Proposition: L-CYSTEINE HCL complies with relevant regulations and guidelines

Warning: Avoid contact with eyes. In case of contact, rinse thoroughly with water. Use appropriate protective equipment when handling. Keep out ofreach of children.
