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

Country of Origin: India

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.

General Description:
L-Cysteine is a semi-essential amino acid found in protein-rich foods such as poultry, eggs, dairy, and red peppers. In its supplemental form, it's often derived from animal or synthetic sources. L-Cysteine plays a crucial role in protein synthesis, and as an antioxidant, it helps to protect cells from damage by free radicals.

  • Uses in the Cosmetic Industry:
    In the cosmetic industry, L-Cysteine serves several purposes in formulations, including:
  • Hair Care: L-Cysteine is used in hair care products such as shampoos, conditioners, and hair treatments. It helps to strengthen hair fibers, improve elasticity, and reduce breakage. L-Cysteine is also used in hair straightening treatments due to its ability to break down disulfide bonds in hair proteins.
  • Skin Care: It is used in skincare products for its antioxidant properties, helping to protect skin cells from oxidative stress and environmental damage. L-Cysteine can promote collagen production, which supports skin elasticity and firmness.
  • Antioxidant: L-Cysteine acts as an antioxidant, scavenging free radicals that contribute to aging and skin damage. This makes it beneficial in anti-aging formulations and products aimed at reducing the appearance of fine lines and wrinkles.
  • Conditioning Agent: In hair care products, L-Cysteine acts as a conditioning agent, improving the texture and manageability of hair. It can also help to repair damaged hair and restore its natural shine.

Hazard:
While L-Cysteine is generally considered safe for use in cosmetics, there are some potential hazards and considerations:

  • Skin Sensitivity: Some individuals may experience skin irritation or allergic reactions to L-Cysteine, especially if they have sensitive skin or allergies to amino acids. Patch testing is recommended, especially for new products or formulations.
  • Regulatory Status: L-Cysteine is approved for use in cosmetics by regulatory agencies such as the FDA and the European Commission. It is considered safe when used within recommended concentrations and guidelines.
  • Quality Control: The source and purity of L-Cysteine can vary, affecting its effectiveness and safety. Cosmetic manufacturers should ensure they source high-quality, pharmaceutical-grade L-Cysteine for their formulations.
