Are you really able to give informed consent to ingesting, applying or even having injected products that contain additives/excipients such as Polysorbate 80 which is commonly used in many products including food, personal care and pharmaceuticals (including current forms of traditional Chinese medicines!) — and which many (if not all) people have exposed to (internally and externally), in one way or another, on a regular basis for the past 80 years?
Polysorbate 80 (also known as Tween 80 or E433) is a nonionic surfactant widely used in the food, pharmaceutical, and cosmetic industries as an emulsifier, solubilizer, and stabilizer. While generally recognized as safe (GRAS) by regulatory agencies, emerging research has raised concerns about its potential health effects.(FOODADDITIVES, eatoravoid.com)
Common Use Cases
1. Food Industry
Polysorbate 80 is utilized to improve texture, stability, and shelf life in various food products. It is commonly found in:
- Ice cream (up to 0.5%)
- Salad dressings
- Baked goods
- Pickles
- Whipped toppings
- Gelatin desserts
- Sauces (FOODADDITIVES, Food & Wine)
Regulatory bodies such as the U.S. Food and Drug Administration (FDA), European Food Safety Authority (EFSA), and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) have approved its use, setting acceptable daily intake (ADI) levels at 25 mg/kg body weight per day .(FOODADDITIVES)
2. Pharmaceutical Applications
In the pharmaceutical industry, Polysorbate 80 serves as an excipient to enhance the solubility and stability of active ingredients. It is present in:
- Intravenous formulations (e.g., amiodarone)
- Vaccines (e.g., influenza, COVID-19)
- Oral and topical medications (Drugs.com, Wikipedia)
Its inclusion helps in the effective delivery of drugs by improving their dispersion and absorption .
3. Cosmetic and Personal Care Products
Polysorbate 80 is also found in:
- Lotions
- Creams
- Mouthwashes
- Eyedrops (eatoravoid.com, PubMed)
In these products, it functions as a surfactant and emulsifier, aiding in the uniform distribution of ingredients .(Wikipedia)
Potential Health Risks
1. Gastrointestinal and Metabolic Effects
Recent studies suggest that Polysorbate 80 may disrupt the gut microbiome, leading to inflammation and metabolic disturbances. In animal models, it has been associated with: (PubMed)
- Altered gut microbiota composition
- Increased intestinal permeability
- Low-grade inflammation
- Elevated blood sugar levels (eatoravoid.com, Food & Wine)
These changes could potentially contribute to conditions like obesity, diabetes, and inflammatory bowel diseases. (Food & Wine)
2. Cognitive Impairment
A 2024 study using a mouse model indicated that long-term exposure to Polysorbate 80 exacerbated age-related cognitive decline. The proposed mechanism involves: (PubMed)
- Disruption of the gut-brain axis
- Altered bile acid metabolism
- Neuroinflammation
- Blood-brain barrier impairment (PubMed)
These findings suggest a potential link between dietary emulsifiers and neurodegenerative processes .(PubMed)
3. Hypersensitivity Reactions
Although rare, Polysorbate 80 has been implicated in non-immunologic anaphylactoid reactions, particularly when administered intravenously. Cases have been reported in patients receiving medications containing Polysorbate 80, leading to symptoms such as: (PubMed, Drugs.com)
- Anaphylactic shock
- Hypotension
- Syncope (PMC, eatoravoid.com)
These reactions are thought to result from direct mast cell activation rather than IgE-mediated mechanisms .(PubMed)
4. Carcinogenicity and Toxicity
Long-term studies in rodents have yielded mixed results regarding the carcinogenic potential of Polysorbate 80. Some findings include:
- Increased incidence of adrenal medullary tumors in male rats
- Forestomach inflammation and ulcers in mice
- No significant mutagenic effects observed (PubMed)
These outcomes suggest that while Polysorbate 80 is not strongly carcinogenic, high doses may pose certain risks. (PubMed)
Conclusion
Polysorbate 80 is widely used across various industries due to its functional properties. While generally considered safe at approved levels, emerging research highlights potential health concerns, particularly related to gut health, metabolic function, and immune responses. Further studies are needed to fully understand these effects in humans. (Food & Wine)
For individuals concerned about exposure, reducing intake of ultra-processed foods and consulting healthcare providers regarding medications containing Polysorbate 80 may be advisable. (Food & Wine)

If you have any health concerns then you are advised to speak with your medical advisor or general practitioner (BUT do not expect them to know anything very much about Polysorbate 80 or other excipients/additives used in your food, personal care and even many pharmaceutical products — other than that it it HAS, in the past 80 years, been considered a ‘generally safe’! This status is currently under question and being investigated and you might wish to make your own alternative efforts to confirm the details mentioned in this article BEFORE continuing to consume products that contain this additive/excipient: NOTE — if you are currently taking any medicines that you discover may contain this ingredient DO NOT stop taking them without consulting your Doctor. If you are eating foods or use cosmetics that contain this chemical you might wish to avoid them and look for alternatives.)
