Tween T-20 coconut acid, with the chemical name Polyoxyethylene (20) Sorbitan Monococoate (CAS No.: 9005-64-5), belongs to the polysorbate class of non-ionic surfactants. It is polymerized from sorbitan cocoate and 20 ethylene oxide molecules, exhibiting unique hydrophilic-lipophilic balance characteristics. This product shows excellent chemical stability in acidic, alkaline, and hard water media. It is classified as low toxicity or practically non-toxic, with no skin irritation and high safety.
Its core functions include four aspects: Efficient emulsification – quickly reducing oil-water interfacial tension to form stable and fine O/W emulsions; Excellent solubilization – effectively improving the solubility and dispersion uniformity of poorly soluble active ingredients in the aqueous phase; Superior wetting and spreading properties – significantly enhancing the spreading speed and coverage area of liquids on solid surfaces; Good dispersibility – effectively preventing secondary aggregation of solid particles and maintaining long-term stability of the suspension system.
As a highly effective emulsifier and solubilizer, it is widely used in creams, lotions, makeup removers, toners, facial cleansers, and shampoos. It helps to blend oily actives and fragrances, imparting a refreshing, non-greasy skin feel while ensuring a fine and stable product texture.
Used as an efficient solubilizing carrier and emulsifier to enhance the solubility and bioavailability of lipophilic drugs in aqueous systems. Suitable for oral liquids, injections, and topical ointments, ensuring precise delivery of active ingredients.
Conforms to the standards of INS 432 / E432 as a food emulsifier, used in baking fats, dairy beverages, seasoning sauces, etc. It helps improve mixing uniformity and mouthfeel, delay starch aging, and maintain product softness and excellent taste.
As an antistatic agent and softening treatment agent, it effectively eliminates static electricity accumulation on fibers during high-speed spinning and weaving processes, reduces friction damage, and imparts a smooth, fluffy feel to fabrics.
Used as a green pesticide emulsifier and tank-mix adjuvant, it significantly reduces the surface tension of spray solutions, enhancing wetting, spreading, and penetration on plant leaves, thereby improving efficacy and rainfastness. Its effects are particularly prominent in suspension concentrates and microemulsions.
In industrial detergent formulations, it serves as a core emulsifying and wetting component, enhancing the stripping and dispersion of oil stains. In cutting fluids and lubricants, it provides auxiliary emulsification, lubrication, and anti-rust functions, ensuring processing precision and surface finish of workpieces.
