Uses of CAS 77 92 9

Methyl salicylate has numerous applications in various macrocosm and microcosm industries. Some of these industries include pharmaceutical, cosmetic and personal care, and agricultural industries.

Pharmaceuticals and topical medicine

In pharmaceuticals, methyl salicylate is an active ingredient in topical analgesics. These topical analgesics are in the form of creams, balms, and liniments. These products act as counterirritants. When applied to the skin, they provide a cooling sensation that's soon followed by warmth. This helps in relieving muscle and joint pain. Methyl salicylate is also used in producing medicinal flavoring agents. These flavoring agents are intended for cough syrups and other medical suspensions.

Cosmetics and personal care

The aroma of methyl salicylate is one of the key reasons it's used in cosmetics and the personal care realm. It's used in products like lotions, creams, and perfumes. In these products, it provides a lingering pleasant smell. Furthermore, it has some moisturizing nature that aids in skin hydration when included in cosmetics. This makes the product feel better on the user's skin.

Agriculture

Methyl salicylate is one of the most favored natural repellents in the agriculture sector. It has been shown to effectively repel a range of pests. This reduces the need for synthetic chemical pesticides. Beyond pest repelling, methyl salicylate is also under research for its potential role in plant defense mechanisms. This observation was based on its ability to induce resistance in plants.

Food and beverages

Methyl salicylate is commonly used as a flavoring agent in food and beverage products. This is mostly available in the bitter almond oil and root beer flavors. It offers a distinctive sweet mint flavor that's widely appealing. This makes it a common choice for flavoring methyl salicylate oil products like candies, beverages, and even some baked goods. It's also used in certain dental products to mask unpleasant taste and provide a fresher breath.

How to choose CAS 77 92 9

There are numerous factors to consider when choosing methyl salicylate. Some of them include purity, grade, source, storage conditions, and regulatory compliance. Below is a detailed breakdown of these factors.

• Purity and quality: Purity is the most critical factor when choosing methyl salicylate. This is due to the compound's broad usage in sensitive applications like the pharmaceutical and food industries. It's also essential to acquire the product from reputable suppliers who provide third-party lab test results confirming purity and methyl salicylate's content. Purchasing methyl salicylate with a high purity percentage (usually over 95%) is important for effective performance.
• Industrial and pharmaceutical grade: The grade of methyl salicylate depends on the use. For medicinal products, methyl salicylate pharmaceutical grade is necessary. For agro or industrial applications, go for the industrial or technical grades. These grades have varying impurities that are acceptable for non-consumable uses.
• Natural vs synthetic: Methyl salicylate can be naturally extracted or synthetically manufactured. Natural methyl salicylate, extracted from plants like wintergreen, is mostly higher in value. This is due to its "natural" labeling. On the other hand, synthetic methyl salicylate is commonly used in industries due to its cost-effectiveness and availability.
• Packaging and storage: Purchase methyl salicylate that has been properly packaged. Usually, it is stored in airtight containers, typically dark glass or plastic, to avoid degradation due to light or moisture exposure. When delivered, ensure the containers are sealed properly to avoid contamination. Methyl salicylate must also be stored in cool and dry areas . This helps maintain its integrity and effectiveness, especially when used for pharmaceutical or cosmetic purposes.
• Compliance and certification: When purchasing chemicals like this one, it's important to ensure that it has supplier certification. These certifications include ISO compliance, Good Manufacturing Practices (GMP), and ROHS. These certifications indicate that the product meets internationally recognized standards for quality and safety.

Side Effects of CAS 77 92 9

The exposure level of methyl salicylate determines whether one will experience some side effects or not. Low exposure levels are usually safe and might be even beneficial. However, high exposure levels or misuse can cause side effects. Some of these side effects include skin irritation, respiratory issues, and toxicity when ingested.

Skin irritation

Methyl salicylate is a common ingredient in topical analgesics. These analgesics include creams and gels. Even though it's generally regarded as safe, it can irritate sensitive skin or in rare cases. That said, buyers should take note of such potential side effects when purchasing this compound. They should ensure they properly vet the product's quality. Moreover, they should provide clear and informative product descriptions that highlight the main ingredients. This will help people with sensitive skin avoid products that may cause allergic reactions to them.

Inhalation risks

Inhalation of methyl salicylate can cause respiratory problems if done in large concentrations. Some of these respiratory problems include headaches, dizziness, and even nausea. This compound has a strong aroma. Therefore, prolonged inhalation can cause such symptoms. Buyers should create awareness about these inhalation risks when purchasing this compound. They should ensure they get quality compounds from reputable suppliers. Moreover, they should get those suppliers to provide product high-quality standards certificates.
