General Description
Triclosan is a synthetic, broad-spectrum antimicrobial agent widely recognized for its ability to inhibit the growth of bacteria, fungi, and some viruses. It is a white crystalline powder, sparingly soluble in water but soluble in alcohols and oils. For decades, Triclosan has been incorporated into personal care and cosmetic formulations for its preservative and antibacterial properties. Although effective, its use has become increasingly restricted in many regions due to environmental concerns and potential health risks.
Uses in the Cosmetics Industry
Historically, Triclosan was used in a wide range of cosmetic and personal care products, including:
- Soaps & Hand Washes: Provided antibacterial cleansing action.
- Toothpaste & Mouthwash: Reduced oral bacteria and plaque formation.
- Deodorants: Controlled odor by inhibiting odor-causing bacteria.
- Skin Care Products: Acted as a preservative to prevent microbial growth.
- Cosmetic Preservative: Helped extend the shelf life of formulations.
While Triclosan was valued for these applications, its cosmetic use is now limited or banned in several markets (e.g., EU and FDA-regulated products) due to safety and environmental considerations.
Hazards
Triclosan poses several potential risks that formulators must be aware of:
- Skin Irritation: Can cause dryness or irritation with prolonged use, especially in sensitive individuals.
- Allergic Reactions: Rare but possible, particularly in people prone to skin sensitivities.
- Hormonal Concerns: Some studies suggest that Triclosan may act as an endocrine disruptor, influencing hormone regulation.
- Antibiotic Resistance: Overuse has been linked to contributing to antimicrobial resistance.
- Environmental Impact: Persistent in aquatic environments; may accumulate and negatively affect aquatic organisms.
Due to these risks, many cosmetic regulatory bodies have placed strict limits or outright bans on its use in personal care products.
Storage & Stability
- Storage: Store in a tightly closed container in a cool, dry, well-ventilated place away from heat and sunlight.
- Stability: Stable under normal conditions but may degrade with prolonged exposure to high heat or strong oxidizing agents.
CAS Number: 3380-34-5
INCI: Triclosan
Composition: Triclosan is a chlorinated aromatic compound, typically synthesized through chemical processes. It consists of a phenyl ring with chlorinated substituents and a functional group containing an ether linkage.
Purity Grade: No purity grade applicable
Appearance: Triclosan is usually a white to off-white crystalline powder or solid.
Solubility: Triclosan is sparingly soluble in water but soluble in organic solvents such as ethanol, methanol, and acetone.
Preservation: Triclosan itself exhibits antimicrobial properties, which can help preserve products in which it is used. However, its use as a preservative in personal care products has been limited due to concerns about its potential impact on human health and the environment.
Storage: Store in a closed container at a dry place at room temperature
Raw Material Source : The raw materials for Triclosan production include phenol and chlorine, which undergo chlorination and synthesis processes to produce the final compound. These raw materials are derived from petrochemical sources and undergo rigorous purification to obtain high-purity Triclosan.
Manufacture: Triclosan is manufactured through a series of chemical reactions involving the chlorination of phenol to form 2,4,6-trichlorophenol, which is then further reacted with 4-hydroxybenzaldehyde to produce Triclosan. The synthesis typically involves multiple steps under controlled conditions to achieve the desired purity and yield.
Animal Testing: Not animal tested
GMO: GMO-free (does not contain plant-derived components)
Vegan: Does not contain animal-derived components
Proposition: TRICLOSAN 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 of reach of children.
