Hydrogenated Polyisobutene and Polyisobutylene

Hydrogenated polyisobutene is a compound created via hydrogenation. Hydrogenation refers to a reaction where hydrogen alters the properties of a select substance. Polyisobutene, in its non-hydrogenated form, is a synthetic polymer; it’s a liquid with film-forming and adhesive properties that make it valuable in cosmetics, though Heal Yes! avoids it, and we’ll explain why in a moment.

In the cosmetics industry, hydrogenated polyisobutene is a popular ingredient because of the emollient and a thickening properties it can impart in skincare products and makeup, including, popularly, lip glosses. . . .



The use of hydrogenated polyisobutene in lip gloss is so popular because it lends a smooth and glossy texture, increases shine, and provides hydrating properties, all desirable when it comes to lip glosses.

One of the perks of hydrogenated polyisobutene in cosmetics is its impressive ability to prevent water loss from the skin, meaning it helps ‘lock in’ moisture, keeping skin (or lips) soft.

Another perk is the fact that hydrogenated polyisobutene has a non-greasy texture and a non-sticky feel, and many people prefer makeup, especially glosses, to be just that: non-sticky in feel and non-greasy in texture and feel.

As stated above, Heal Yes! avoids this ingredient despite its ‘pros’ listed above. First of all, polyisobutene can negatively affect those who are sensitive or allergic to it, leading to skin irritation or adverse reactions. Natural alternatives are often preferred among those seeking to eliminate toxins and lead their healthiest lifestyle, so the strong ‘synthetic’ factor to polyisobutene is off-putting.

Natural options to replace hydrogenated polyisobutene might include plant-based oils and waxes, such as but not limited to organic jojoba oil, almond oil, coconut oil, and shea butter. These nature-provided alternatives offer similar moisturizing and protective properties while being derived from sustainable sources that organic ingredient-loving aficionados approve of.

Hydrogenated polyisobutene might come with some notable performance advantages when used in cosmetics—especially lip glosses—but you won’t find it in Heal Yes! products.

Here are a few additional questions and answers to summarize the ingredient:

Is polyisobutene safe for skin?

Polyisobutene is generally regarded as safe for use in skincare products in accordance with industry standards and regulations. It forms a protective barrier on the skin, which can help lock in moisture, making it suitable for lip balms, moisturizers, and products designed to hydrate and safeguard the skin. Moreover, it is often included in non-comedogenic formulations, reducing the likelihood of pore clogging and acne breakouts. Nevertheless, some may experience skin sensitivities or allergies to polyisobutene.

The overall safety of a skincare product relies on its complete formulation, encompassing the concentration of polyisobutene and other ingredients. Careful reading of product labels and considering potential interactions with other skincare products is imperative.

Is polybutene good for your skin?

Polybutene is commonly used for its moisturizing properties and ability to create a smooth, glossy texture, which can purportedly be good for your skin, especially if you have dry or dehydrated skin, as it helps lock in moisture and prevent moisture loss; however, its effects can vary from person to person. Some individuals may have sensitivities or allergies to specific cosmetic ingredients, polybutene being no exception. . . .

Ultimately, whether polybutene is "good" for your skin depends on your skin type, specific concerns, and the overall formulation of the skincare product.

Is polyisobutylene toxic? Is polyisobutylene bad for you? What are the side effects of polyisobutylene?

Polyisobutylene (PIB) has a history of use in various industrial and consumer applications, including in the food, pharmaceutical, and cosmetic industries. The safety of PIB can be influenced by factors such as sourcing, purity, and manufacturing practices. Here are some considerations:


The quality and safety of polyisobutylene can be influenced by its source. PIB used in consumer products should be sourced from reputable suppliers who adhere to quality and safety standards.


The purity of polyisobutylene is essential. Impurities in polyisobutylene can potentially pose risks. High-quality polyisobutylene used in consumer products should undergo rigorous purification processes to remove impurities.

Manufacturing Concerns:

The safety of products containing polyisobutylene also depends on the overall formulation and manufacturing processes. Products should be manufactured following good manufacturing practices (GMP) to ensure quality and safety.

Skin Sensitivities:

While polyisobutylene is generally well-tolerated, individual skin sensitivities can vary. If you notice adverse reactions or skin irritations after using a product containing polyisobutylene, it's advisable to discontinue use and consult with a healthcare professional.

In a nutshell, polyisobutylene can be safe when used in consumer products, but the safety can be influenced by factors such as sourcing, purity, and manufacturing practices. Consumers should choose products from reputable brands and be aware of any sensitivities they may have to specific ingredients. Additionally, adhering to product usage guidelines and discontinuing use in case of adverse reactions is important. If you have specific concerns about a product or ingredient, consult with a healthcare professional or dermatologist for personalized guidance.

What does polyisobutene do in lip gloss, specifcially?

Polyisobutene plays a pivotal role in lip gloss formulations, primarily contributing to the product's texture and performance. It is responsible for the glossy and reflective shine that characterizes lip gloss, enhancing the lips' visual appeal.

Beyond aesthetics, polyisobutene functions as a moisture-locking agent, creating a protective barrier on the lips that prevents moisture loss, keeping them hydrated and preventing dryness.

This dual-purpose of visual enhancement and moisturization makes lip gloss not only visually appealing but also functional. Furthermore, polyisobutene assists in improving the gloss's longevity, helping it adhere to the lips and maintain its shine over time.

Additionally, its presence ensures a smooth and even application, providing a uniform and attractive finish.

Overall, polyisobutene's role in lip gloss enhances both the cosmetic and functional aspects of the product, delivering a glossy, comfortable, and moisturizing lip experience.

Is polyisobutylene natural?

Polyisobutylene is not a naturally occurring substance. It is a synthetic polymer, which means it is artificially produced rather than being found in nature. PIB is typically created through the process of polymerization using isobutylene, a hydrocarbon derived from petroleum or natural gas feedstocks.

Since Heal Yes! avoids polyisobutylene, what natural and organic alternatives are used?

Go-to ingredients such as beeswax, shea butter, coconut oil, and various plant-based oils are often used as substitutes for synthetic polymers like polyisobutylene; these natural alternatives can provide similar moisturizing and barrier-forming benefits without the concerns associated with synthetic ingredients.

Organic ingredients and finished formulas often prioritize using natural and sustainable ingredients, which may align with environmentally conscious consumer preferences and the needs of those with sensitive and reactive skin. Entrust the cleanest-of-clean Heal Yes! cosmetic range today.
