INCI Name and Common References

International Nomenclature of Cosmetic Ingredients name: Polyisobutene Common terms: Synthetic polymer, emollient Nicknames: PIB, butyl rubber

Function

Polyisobutene is a synthetic polymer that is commonly used in cosmetic formulations as a thickening agent, emollient, and binder. It helps to improve the texture and consistency of products, making them easier to apply and spread evenly on the skin. Polyisobutene also has moisturizing properties, which can help to hydrate and soften the skin. Additionally, it can act as a film-forming agent, creating a protective barrier on the skin that helps to prevent moisture loss and protect against environmental stressors. Overall, polyisobutene is a versatile ingredient that plays an important role in many different types of cosmetic formulations.

Science

Polyisobutene is a synthetic polymer that is commonly used in cosmetics and personal care products due to its unique physical properties. It is a viscous liquid that is highly resistant to water and other solvents, making it an effective emollient and moisturizer. Polyisobutene also has a high molecular weight, which allows it to form a protective barrier on the skin, preventing moisture loss and protecting against environmental stressors. Additionally, its non-comedogenic properties make it suitable for use in products designed for acne-prone skin. Overall, the physical properties of polyisobutene make it an effective ingredient in a wide range of cosmetic and personal care products.

Benefits

Polyisobutene is a versatile ingredient that offers several skincare benefits. It is known to provide excellent moisturization and hydration to the skin, making it soft and supple. It also helps to improve the skin's barrier function, preventing moisture loss and protecting it from environmental stressors. Polyisobutene is non-comedogenic, which means it does not clog pores, making it suitable for all skin types. Additionally, it has a silky texture that helps to smooth out fine lines and wrinkles, giving the skin a more youthful appearance. Overall, polyisobutene is a valuable ingredient in skincare products that can help to improve the overall health and appearance of the skin.

Negatives

Polyisobutene is a synthetic polymer that is commonly used in cosmetics and personal care products as a thickening agent, emollient, and binder. While it is generally considered safe for use in these products, there are some potential side effects, sensitivities, and interactions that should be considered. One possible side effect of polyisobutene is skin irritation or allergic reactions. Some people may be sensitive to this ingredient and experience redness, itching, or swelling when it comes into contact with their skin. If you experience any of these symptoms, you should discontinue use of the product and consult with a healthcare professional. Polyisobutene may also interact with other ingredients in cosmetic and personal care products. For example, it may interact with certain preservatives or fragrances, which could lead to increased skin irritation or other adverse effects. It is important to read the labels of all products carefully and to avoid using products that contain ingredients that you are allergic to or sensitive to. In addition, polyisobutene may have some potential health risks if ingested or inhaled. While it is generally considered safe for use in cosmetics and personal care products, it is important to avoid ingesting or inhaling this ingredient, as it may cause respiratory or digestive problems. Overall, polyisobutene is a safe and effective ingredient that is commonly used in cosmetics and personal care products. However, it is important to be aware of the potential side effects, sensitivities, and interactions that may occur, and to use these products with caution. If you have any concerns or questions about the use of polyisobutene or any other ingredient in your cosmetics or personal care products, you should consult with a healthcare professional.

Source

Polyisobutene is a synthetic ingredient that is derived from the polymerization of isobutene, a hydrocarbon gas that is typically obtained from petroleum refining. The processing pathway for polyisobutene involves the use of catalysts to initiate the polymerization reaction, which results in the formation of a long chain of repeating isobutene units. The resulting polymer can be further processed to achieve different molecular weights and properties, depending on the intended application. Polyisobutene is commonly used in the cosmetics industry as a thickening agent, emollient, and binder.

Safety

Polyisobutene has a low safety rating score according to the EWG Skin Deep database. It has been rated as a moderate hazard ingredient due to its potential to cause skin irritation and allergic reactions. However, it is generally considered safe for use in cosmetics and personal care products in concentrations of up to 10%. Other sources also suggest that polyisobutene is safe for use in cosmetics and personal care products when used as directed. Overall, while there are some concerns about its safety, polyisobutene is generally considered to be a safe ingredient.

Sustainability

Polyisobutene is a synthetic polymer that is commonly used in the cosmetics industry as a thickening agent and emollient. While it is not directly harmful to the environment, the production of polyisobutene can have negative environmental impacts. The production of polyisobutene requires the use of fossil fuels, which contributes to greenhouse gas emissions and climate change. Additionally, the manufacturing process can generate waste and pollution, which can harm local ecosystems and communities. In terms of ethical sourcing practices, polyisobutene is not typically sourced from natural resources, so issues of ethical sourcing do not apply. However, it is important for companies to ensure that the production of polyisobutene is conducted in a responsible and sustainable manner to minimize its environmental impact. This can include using renewable energy sources, reducing waste and pollution, and implementing recycling programs.

Conclusion

In conclusion, polyisobutene is a versatile ingredient that is commonly used in the cosmetic industry as a thickening agent and emollient. Its unique chemical structure allows it to provide long-lasting hydration and protection to the skin. While there are some concerns about its potential to clog pores and cause skin irritation, it is generally considered safe for use in cosmetics. Polyisobutene can be derived from both petroleum and plant-based sources, but the sustainability of its production depends on the specific source. Overall, polyisobutene is a valuable ingredient that can provide numerous benefits to the skin, but it is important to consider its potential drawbacks and sustainability when choosing products that contain it.
