Different types of Hydrogenated Polyisobutene
Hydrogenated polyisobutene is a polymer with an aliphatic structure, also called “liquid isoparaffin” (Japanese name).
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.
Interest of Hydrogenated Polyisobutene in cosmetics
In cosmetics, in the make-up and personal care market, it is an ideal multi-purpose ingredient to bring emollience and/or texture to your formulas while controlling your formulation costs.
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.
Due to these various properties, hydrogenated polyisobutene is recommended in various cosmetic formulations, including make-up products such as lip glosses, lipsticks, lip balms, eye products, etc., as well as in hair products, in particular hair styling waxes. It is also recommended in face care applications including aftershave gels and balms. This ingredient also provides sensoriality in cosmetics formulations, especially in care products.
