�� Basic Information

• Chemical name: Methyl 2-hydroxybenzoate

• Formula: C₈H₈O₃

• CAS No.: 119-36-8

• Appearance: Colorless to pale yellow oily liquid

• Odor: Strong wintergreen scent

• Solubility: Slightly soluble in water; miscible with alcohol, ether, and oils

�� Common Uses

1. Pharmaceuticals / Topical Analgesics

   • Found in ointments, liniments, and rubefacient creams for muscle and joint pain

   • Provides warming sensation on the skin

2. Cosmetics & Personal Care

   • Flavoring in mouthwashes, toothpaste, and chewing gum (limited concentration)

   • Fragrance in creams and lotions

3. Industrial Applications

   • Used in fragrances, perfumes, and as a chemical intermediate

�� Key Properties & Benefits

• Analgesic & anti-inflammatory: Mild topical pain relief

• Aromatic: Gives characteristic wintergreen scent

• Solvent-friendly: Mixes well with oils and alcohols

⚠️ Safety & Handling

• Toxic if ingested in large amounts (especially for children)

• Can cause skin irritation if overused

• Avoid contact with eyes and mucous membranes

• Store in tightly sealed containers, away from heat and light

If you want, I can make a quick reference table of methyl salicylate vs menthol vs camphor, showing their topical uses, sensory effects, and formulation tips. It’s very handy for pain-relief and cosmetic products.

Glycerine (also called Glycerol) is a widely used humectant, solvent, and moisturizer in pharmaceuticals, cosmetics, and food.

🧪 Basic Information

• Chemical name: Glycerol

• Formula: C₃H₈O₃

• CAS No.: 56-81-5

• Appearance: Colorless, odorless, viscous liquid

• Solubility: Miscible with water and alcohol

• Boiling point: 290 °C

• Hygroscopic: Absorbs moisture from air

🌟 Common Uses

1. Pharmaceuticals

   • Solvent for oral and topical medications

   • Base for cough syrups and elixirs

   • Laxative in high doses

2. Cosmetics & Personal Care

   • Moisturizers, lotions, creams, and hair care products

   • Humectant to retain skin moisture

   • Improves texture and spreadability of formulations

3. Food Industry

   • Sweetener, humectant, and stabilizer in bakery, confectionery, and beverages

4. Industrial Applications

   • Antifreeze, plasticizer, and chemical intermediate

💡 Key Properties & Benefits

• Humectant: Draws water into skin or product

• Viscosity modifier: Adds body to creams and syrups

• Solvent: Dissolves water-soluble ingredients

• Non-toxic and safe: GRAS status in food and cosmetic products

⚙️ Handling & Storage

• Store in a cool, dry place, tightly closed

• Hygroscopic—avoid moisture contamination

• Non-hazardous, but avoid prolonged contact with eyes

If you want, I can make a comparison table of Glycerine vs Propylene Glycol vs Butylene Glycol, showing solubility, humectant strength, and cosmetic/pharma uses—it’s extremely useful for formulation purposes.
