Comparing Hydrogenated Polyisobutene (300cs), Hydrogenated Polyisobutene (4cs), and Polyglyceryl-2 isostearate/dimer dilinoleate copolymer (PIDDC)

These three ingredients are all used in cosmetic formulations, particularly in oil-based products, but they have different characteristics, especially regarding viscosity.

• Hydrogenated Polyisobutene (4cs): This is a light, clear hydrocarbon oil with a low viscosity (around 3.6 cs). It acts as an emollient, making the skin feel soft, and can help reduce the stickiness of a formula.
• Hydrogenated Polyisobutene (300cs): This is a more viscous, clear hydrocarbon oil with a higher viscosity (around 300 cs). It is commonly used in makeup products for its good gloss, adherence to the skin, and stability.
• Polyglyceryl-2 isostearate/dimer dilinoleate copolymer (PIDDC): This is described as a viscous oil and a water-oil binder specifically developed for lip gloss formulations. It provides shine, comfort, moisture retention, and good adherence, making it feel substantial and long-lasting on the lips.

While all three are oils used in cosmetics, their textures and primary functions differ due to their varying viscosities and chemical structures.

Viscosity Comparison:

Based on the viscosity information and descriptions:

• The least viscous is Hydrogenated Polyisobutene (4cs).
• The most viscous is likely Polyglyceryl-2 isostearate/dimer dilinoleate copolymer (PIDDC), given its description as a viscous oil and binder specifically for lip gloss, followed closely by Hydrogenated Polyisobutene (300cs).
