Polyisobutene and Hydrogenated Polyisobutene are synthetic polymers used in cosmetics and personal care products. Polyisobutene increases the thickness of the lipid portion of cosmetics, while Hydrogenated Polyisobutene acts as a lubricant on the skin's surface, giving it a soft and smooth appearance. Hydrogenated Polyisobutene is also used as a fixating agent in cosmetic applications.
Restoring skin suppleness: Hydrogenated Polyisobutene helps restore skin suppleness by preventing insensible water loss. Preventing insensible water loss: Hydrogenated Polyisobutene forms a protective layer on the skin's surface, preventing insensible water loss and keeping the skin hydrated. Providing a smoothing effect to the skin: Hydrogenated Polyisobutene has a smoothing effect on the skin, making it feel softer and smoother. Increasing pigment dispersion: Hydrogenated Polyisobutene helps disperse pigments evenly in cosmetic formulations, resulting in a more uniform and natural appearance. Waterproofing agent: Hydrogenated Polyisobutene acts as a waterproofing agent, making it suitable for use in sunscreens and other water-resistant products. Fixating agent: Hydrogenated Polyisobutene is used as a fixating agent in cosmetic applications, helping to keep makeup and other products in place. Improving SPF retention after exposure to water: Hydrogenated Polyisobutene helps improve the retention of SPF after exposure to water, making it more effective in protecting the skin from the sun's harmful rays. Providing shine and a silky feel to hair: Hydrogenated Polyisobutene provides shine and a silky feel to hair, making it look and feel healthier. Providing hold and shine to lipstick, gloss and mascara formulations: Hydrogenated Polyisobutene helps provide hold and shine to lipstick, gloss, and mascara formulations, making them last longer and look more vibrant.
All skin types except those that have an identified allergy to it.
It has been linked to some mild irritation in some people. Generally, the irritation occurs in skin types that are already inflamed or sensitized.

Hydrogenated Polyisobutene can be of different molecular weights, which determines the viscosity and consistency of the ingredient: * the lower molecular weight is semi-liquid and viscous, * the higher molecular weight is more solid and elastic. Lower molecular weight hydrogenated polyisobutene has similar properties to squalane, such as restoring skin suppleness and preventing insensible water loss. It provides a smoothing effect to the skin and increases pigment dispersion. Thanks to its non-greasy feel and soft texture, it brings sensoriality to your formulas. High molecular weight hydrogenated polyisobutene is a waterproofing agent and fixating agent. It also improves SPF retention after exposure to water, making it easy to incorporate into sun protection products. Versagel ME products are patented gelled emollients (mineral oil-free alternative for labeling) that are suitable for use in many cosmetic and personal care applications. Versagel ME products use Hydrogenated Polyisobutene (PIB) as the base and they exhibit extraordinarily good clarity, excellent thermal and UV stability, and versatile chemical compatibility. A unique property of these materials is their suspension capability for fine particles. Depending on the particle size and surface affinity, these materials can be utilized to maintain stable suspensions of zinc oxide, titanium dioxide, iron oxide, talc, decorative glitters, and more. Versagel ME products have excellent clarity that allows unique items such as glitter, wax beads, and other materials to be suspended. They are easier and safer to handle and formulate than gels that use metal stearates or fumed silica. They provide fragrance retention in skincare products and furnish waterproofing properties to sunscreen products. Furthermore, they are hydrophobic, thermally reversible, and without syneresis (oil bleed).
