A 2-year chronic oral toxicity study of Polybutene revealed no gross or microscopic pathological changes, and no changes in body weights or food consumption, hematological results, urology, or tumor formation that could be correlated with Polybutene ingestion, except that in the 20,000 ppm group, three out of six males ...
In summary, Polybutene is considered safe for use in lip gloss and other beauty products. Backed by regulatory approvals and safety studies, it offers both functional benefits and peace of mind for consumers and formulators alike.
Polybutene generally is of low acute toxicity but causes eye irritation (Toxicity Category II). No other toxicological endpoints are of concern for workers or homeowners exposed to polybutene. No food-related uses are registered so dietary exposure is not of concern.
Polybutene is made from petroleum and is a synthetic ingredient.
Part of the reason polybutene is so widely used in cosmetic products is that it's so neutral on the skin. According to Dr. Castilla, the ingredient is non-sensitizing and non-comedogenic and works well with virtually any ingredient.
Polybutene-1 is often referred to as Polybutene, PB, PB-1 or Polybutylene. Polybutene-1 is not sold by PBPSA members for use in pipe applications intended for use in North America, and those parties require their customers or distributors not to sell products made from PB-1 into pipe applications for North America.
In the cosmetics and skincare industry, polyethylene is generally considered a safe ingredient, primarily used as microbeads, thickeners, and stabilizers in a variety of skincare and beauty products.
However, in rare cases, some individuals may experience mild skin irritation or allergic reactions to carbomers. If you experience any adverse reactions, such as redness, itching, or swelling, after using a product containing carbomer, discontinue use immediately and seek medical advice.
Polybutene is a chemically related cosmetic ingredient previously determined to be safe as used in cosmetic products. Polyisobutene is used in cosmetic products as a binder, film former, and nonaqueous viscosity-increasing agent.
Polybutene is an organic polymer made from a mixture of 1-butene, 2-butene, and isobutylene. Ethylene steam cracker C4s are also used as supplemental feed for polybutene. It is similar to polyisobutylene (PIB), which is produced from essentially pure isobutylene made in a C4 complex of a major refinery.
Overall, polybutylene pipes should not completely deter you from purchasing a home you love. You should, however, take some additional steps if you do decide to make a deal on a house with these types of pipes. Hiring a professional plumber is key to ensuring the pipes are still in good shape.
In a carcinogenicity study, Polyisobutene was not carcinogenic, nor did it promote the carcinogenicity of 7,12-dimethylbenz(alpha)anthracene.
The reason for polybutene to be considered non-sustainable is due to its production process, which relies heavily on the non-renewable resource of petroleum. Petroleum is a finite resource and its extraction and processing have significant environmental impacts.
You'll need to begin by determining why polybutene is being called for in a formulation. If it's being used as a rich emollient in a skincare product, I think Lanolin, Brassica Campestris Aleurites Fordi Oil Copolymer, or Lecithin might work as an alternative. Hydrogenated Polyisobutene is not a good alternative.
And preservatives can also be an issue, especially in lip glosses and lipsticks. This may include chemicals such as formaldehyde and methylisothiazolinone.
Polybutene is a oligomeric oil, sometimes derived from petroleum, that is used in its hydrogenated form in cosmetics and beauty products, primarily in lipsticks and balms, as a binder, epilating agent, thickener and lubricant (Wikipedia).
The available human clinical data indicated only very mild effects. Skin tests for sen- sitization, irritancy, phototoxicity, and photosensitization were limited to cosmetic for- mulations. On the basis of the available information, it was concluded that Polybutenes are safe as presently used in cosmetics.
Floor heating
Due to its flexible nature, Polybutene-1 pipe is ideal for use in underfloor central heating systems and variations on existing floors.
Dimethicone is used to form a protective barrier on the skin, decreasing the loss of moisture and providing some protection from irritants or allergens. Experts consider dimethicone to be a safe ingredient with few to no side effects. However, while it is safe for humans, it has a harmful effect on the environment.
Those branded Aacarb, Aacomer and Puroptics, have a potential risk of microbial contamination, which can cause an infection if the gel is used. Investigations are ongoing to determine if there is a link between the infections which have been identified and these products.
As regards gel strength and spreading behaviour, xanthan gum, used at high concentrations (up to 2.0%), is a very good alternative to conventional synthetic gelling or thickening agents such as carbomers.
It safeguards cosmetic products from getting contaminated, ensuring their stability and safety for prolonged use. In addition, unlike some other preservatives, such as parabens, Phenoxyethanol is considered to have a lower risk of skin irritation, making it suitable for all skin types.
No chemical carcinogenicity has been seen in implantation studies, although particles from Polyethylene implants can induce so-called solid-state carcinogenicity, which is a physical reaction to an implanted material.
Is Polyethylene Safe? Polyethylene is considered one of the safest plastics. Clean Production Action named polyethylene, along with polypropylene, one of the “most benign” plastics in their Plastics Scorecard, which evaluates the hazardous effects of various plastics.
Health and Environmental Hazards
Depending on manufacturing processes, PEGs may be contaminated with measurable amounts of ethylene oxide and 1,4-dioxane. The International Agency for Research on Cancer classifies ethylene oxide as a known human carcinogen and 1,4-dioxane as a possible human carcinogen.
