Polyisobutene is a synthetic polymer of isobutylene; used as a film-forming agent.
Polyisobutene (polyisobutylene) is a class of organic polymers prepared by polymerization of isobutene.

The polymers often have the formula Me3C[CH2CMe2]nX (Me = CH3, X = H, F).
They are typically colorless gummy solids.

Polymerization is typically initiated with a strong Brønsted or Lewis acid.
The molecular weight (MW) of the resulting polymer determines the applications.

Polyisobutene is a mixture of oligomers with Mns of about 500
Polyisobutene is used as plasticizers.
Medium and high MW polyisobutenes, with Mn ≥ 20,000, are components of commercial adhesives

Polyisobutene and Hydrogenated Polyisobutene are homopolymers of isobutene.
These ingredients are produced in a wide range of molecular weights.

Polyisobutene functions as a skin-conditioning agent-emollient and nonaqueous viscosity-increasing agent with a wide range of uses in cosmetic formulations.
polyisobutene is a synthetic liquid used to replaced mineral and silicone oils in formulations.

Polyisobutene acts as a waterproofing agent and an emollient.
An emollient helps to maintain the natural skin barrier, prevent moisture loss, and improve the texture of the skincare product.

The skin’s natural barrier is essential to the healthy functioning of the skin.
Disruption of the skin barrier has been linked to the worsening of skin conditions such as eczema, dermatitis, and psoriasis.

Polyisobutene is used in products such as lip gloss, sunscreen, and foundations.
Polyisobutene’s mainly used to increase the longevity of the product on the skin and enhance the dewy, glowing look of the skin.

Polyisobutene works by increasing the thickness of the lipids or oils in product formulations.
Polyisobutene acts as a lubricant on the skin and is often used as a substitute for squalene.
Polyisobutene works as an emollient and waterproofing agent to improve the appearance of the skin and improve the longevity of skincare products on the skin.

POLYISOBUTENE is classified as:
*Binding
*Film forming
*Viscosity controlling

How is Polyisobutene Used?
Polyisobutene is a relatively common skincare ingredient.

Polyisobutene is used in a large variety of products, including lip balm, BB cream, exfoliants, and moisturizers.
There are several qualities of this ingredient that have made it popular with skincare manufacturers.

One of the beneficial qualities of Polyisobutene is its ability to moisturize the skin, making it a popular ingredient in skin creams.
However, Polyisobutene's role in skincare is to reinforce the moisture barrier, rather than to deliver copious amounts of hydration.

For example, hyaluronic acid is typically more useful for drawing moisture to the skin and is highly valued in skincare formulations.
The strength of hydrogenated polyisobutene, on the other hand, comes from its ability to fortify the skin’s natural barrier to reduce moisture loss.

Polyisobutene is also common for hydrogenated polyisobutene to be found in water-resistant sunscreens, as this ingredient allows the sunblock to remain effective even after coming into contact with water.
Additionally, Polyisobutene is valued for its ability to prevent the clumping of pigment in makeup and other skincare products.

This is a critical quality for creating a smooth and enjoyable application, as it keeps the product looking fresh.
Lastly, Polyisobutene is also used to increase the thickness of skin products to create a more luxurious feel.
This can be especially helpful in night-time moisturizers or creams that contain a variety of oils and when the formulation must stay thoroughly

APPLICATIONS:

-tinted moisturizer

-sunscreens

-lip gloss

Polyisobutene is a gas-impermeable synthetic rubber that is manufactured and used globally to produce lubricants, adhesives, sealants
Polyisobutene is a synthetic rubber, or elastomer.

Polyisobutene's special because it's the only rubber that's gas impermeable.
That is, Polyisobutene's the only rubber that can hold air for long periods of time.

Polyisobutene, sometimes called butyl rubber, and other times PIB, is a vinyl polymer.
Polyisobutene's very similar to polyethylene and polypropylene in structure, except that every other carbon is substituted with two methyl groups.

Polyisobutene is made from the monomer isobutylene, by cationic vinyl polymerization.
Polyisobutene and Hydrogenated Polyisobutene are polymers.

In cosmetics and personal care products, Polyisobutene is used in the formulation of lipsticks, they can also be found in eye and facial makeup, skin care products and suntan products.
Polyisobutene dries to form a thin coating on the skin, hair or nails, and is used to hold together the ingredients of a compressed cake.

Polyisobutene acts as a lubricant on the skin’s surface, which gives the skin a soft and smooth appearance.
Polyisobutene is often referred to as butyl rubber and is produced in a wide range of molecular weights; the lower molecular weight Polyisobutenes are very viscous, soft, and tacky semi-liquids while the higher molecular weight Polyisobutenes are tough and elastic rubbery solids.

Polyisobutene is also produced in a wide range of molecular weights and is widely used as a substitute for another cosmetic ingredient, squalene.
Polyisobutene is a homopolymer with isobutene monomers, prepared by a polymerization reaction.

Depending upon its molecular weight it is used commercially as a plasticizer or adhesive.
Low molecular weight Polyisobutene is a viscous, soft, semi-liquid.
Polyisobutene is used in a wide range of cosmetic products.

Use & Benefits:
Polyisobutene is used as a binder, film-former, and non-aqueous viscosity increasing agent in cosmetic products.

As a binding agent, Polyisobutene helps in binding or holding together the ingredients in a cosmetic product in the compressed cake or tablet form of product, for example, a compressed powder or eye shadow.
Polyisobutene works as a non-reactive binder, which is a very important characteristic of a binder.

As a film-forming agent when applied on the hair or skin, Polyisobutene forms a supple, cohesive, and continuous layer.
This layer/film has water-binding properties that leave a silky and smooth effect on the skin.

Polyisobutene also functions as a viscosity increasing agent which when used increases the thickness of the solution and that gives ideal or acceptable viscosity to the product that is just right for use.
Polyisobutene is well tolerated by the skin or quite mild on the skin.
Polyisobutene is used in formulations of make-up products, hair care, and skincare products.

-Very tacky liquid polymer, non-hazardous and no-odor
-Superior corrosion and oxidation-stability against heat, reagent and UV ray
-High thickening efficiency with excellent viscosity-index
-Completely hydrophobic with extremely low electrical conductivity
-Superior solubility to kerosene, coal tar, aromatic compound, hydrogen carbonate chloride, lubricant
-Permanent non-drying properties
-Easy to store with no evaporation or solidification.

Polyisobutene is a polymer (big molecule from repeated subunits) that's used as a gloss improver for lipsticks and lipglosses.
Polyisobutene's stickiness also helps lip products to stay on longer.

Polyisobutene is a non-toxic, hypoallergenic cosmetic ingredient.
Polyisobutene is ideal for lip glosses, body butters, and massage oils.

Most common applications

-Lubricants: 2-stroke Engine oils, Gear oils, Greases, Hydraulic and Metalworking Fluids
