التركيب الكيميائي والتكوين
لمهندسي التركيبات ومديري البحث والتطوير الذين يبحثون عن حل شامل polysorbate 20 TDS overoview, understanding the fundamental chemistry of this surfactant is the first step toward successful application. Polysorbate 20, commercially known as Tween 20, is a non-ionic surfactant belonging to the polysorbate family.
التركيب الجزيئي لمتعدد سوربات 20
ال التركيب الكيميائي لبوليسوربات 20 is derived from the ethoxylation of sorbitan monolaurate. The molecule consists of a hydrophilic head group comprising polyoxyethylene (PEG) chains and a lipophilic tail derived from lauric acid (C12 fatty acid). Specifically, it is formed by the reaction of sorbitan fatty acid ester with approximately 20 moles of ethylene oxide.
This amphiphilic structure allows Polysorbate 20 to function effectively as a wetting agent, stabilizer, and solubilizer in aqueous systems. Unlike its counterparts (such as Polysorbate 60 or 80), the lauric acid tail provides a specific balance suited for lighter formulations and high-clarity applications.

When evaluating raw materials for supply chain integration, precise technical data is paramount. Below is a detailed breakdown of خصائص بوليسوربات 20 and standard specifications found in a Technical Data Sheet (TDS).
قيمة HLB لبوليسوربات 20 والاستحلاب
ال بوليسوربات 20 HLB value is approximately 16.7. This high Hydrophile-Lipophile Balance indicates that the molecule is strongly hydrophilic. Consequently, it is primarily used as an Oil-in-Water (O/W) emulsifier and a solubilizer for essential oils, fragrances, and vitamins in water-based systems.
ملف تعريف الذوبان: الماء والمذيبات العضوية
Formulators rely on قابلية ذوبان بوليسوربات 20 data to determine compatibility. It exhibits the following solubility characteristics:
- Water: Soluble (clear to slightly hazy solution).
- Ethanol/Isopropanol: Soluble.
- Methanol: Soluble.
- Mineral Oil: Insoluble.
- الزيوت النباتية: Generally insoluble (dispersible).
التركيز الحرج للمذيلات (CMC) ونقطة الانصهار
ال تركيز المذيلات الحرج بوليسوربات 20 is a vital metric for determining the minimum amount of surfactant required to form micelles. The CMC is approximately 0.06 mM (approx. 0.007% w/v) at 25°C. This low CMC makes it highly efficient for solubilizing hydrophobic compounds without excessive surfactant usage.
Regarding thermal properties, the نقطة انصهار بوليسوربات 20 is not a singular sharp point due to its complex mixture, but it generally remains a liquid at room temperature, with a pour point typically below -10°C, ensuring ease of handling in cold manufacturing environments.

التطبيقات الوظيفية والسلوك
سلوك المواد الفعالة بالسطح: هل يُكوّن بوليسوربات 20 رغوة؟
A common query in R&D is: هل يُنتج بوليسوربات 20 رغوة؟? Yes, it does possess foaming properties, although it is generally considered a low-to-moderate foamer compared to anionic surfactants like SLS. Its foam is relatively stable but light.
Because of this, it is frequently used in:
- Personal Care: As a mild cleansing agent in baby shampoos and facial washes where low irritation is critical.
- Industrial Applications: As a wetting agent where moderate foam is acceptable or controlled with defoamers.
- Food Systems: As a dispersing agent where foaming is not the primary function, but surface tension reduction is required.
السلامة والمواصفات والامتثال التنظيمي
Ensuring regulatory compliance is central to the value proposition at foodemul.com. We provide full transparency regarding بوليسوربات 20 للسلامة and origin.
الملف السمّي: هل بوليسوربات 20 آمن؟
هل بوليسوربات 20 آمن؟ for consumption and topical application? Yes. It is widely regarded as safe when used within established concentration limits.
- Food Industry: It is approved as a food additive (E432 in the EU / 21 CFR 172.846 in the USA). It acts as an emulsifier in dressings, baked goods, and flavor drops.
- مستحضرات التجميل: The Cosmetic Ingredient Review (CIR) Expert Panel has concluded it is safe for use in cosmetic formulations. It is non-irritating to the skin and eyes at typical use concentrations.
الامتثال الغذائي والأخلاقي: هل بوليسوربات 20 نباتي؟
For brands targeting the plant-based market, the question هل بوليسوربات 20 نباتي؟ is critical. Polysorbate 20 is produced by reacting sorbitol (sugar alcohol) and lauric acid with ethylene oxide.
While lauric acid يستطيع be derived from animal fats, foodemul.com strictly sources vegetable-derived lauric acid (typically from coconut or palm kernel oil) and plant-based sorbitol. Therefore, our Polysorbate 20 is suitable for vegan and vegetarian formulations. We recommend always requesting a “Statement of Origin” to satisfy RSPO and vegan certification requirements.
ملاحظة تنظيمية: While Polysorbate 20 is safe, formulators must be aware of 1,4-dioxane impurities, a byproduct of ethoxylation. Foodemul.com utilizes advanced vacuum stripping technologies to ensure impurity levels are well below strict regulatory thresholds (e.g., EU and California Prop 65 limits).
In summary, this polysorbate 20 TDS overoview highlights the surfactant’s versatility as a high-HLB solubilizer and emulsifier. By leveraging high-purity grades from reliable partners like foodemul.com, formulators can ensure stability, safety, and compliance in their final products.
