Hdi/PPG/Polycaprolactone Crosspolymer

What is Hdi/PPG/Polycaprolactone Crosspolymer?

HDI/PPG/Polycaprolactone Crosspolymer is a synthetic polymer created through the crosslinking of hexamethylene diisocyanate (HDI), polypropylene glycol (PPG), and polycaprolactone monomers. This reaction forms a flexible, three-dimensional network structure typical of polyurethane-based crosspolymers. In cosmetics, it belongs to the category of powder and makeup additives, where it functions by increasing product bulk to enhance texture and spreadability. Its porous structure helps absorb excess moisture, reducing stickiness and clumping in loose or pressed powders. This improves handling during manufacturing and use, allowing for even application without compromising stability. Commonly found in foundations, eyeshadows, and blushes, it contributes to a lightweight feel while maintaining product integrity over time.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Anticaking agent
Prevents powders from clumping by reducing moisture pickup and improving flow, keeping loose and pressed powders uniform during storage and use.
Bulking agent
Increases mass/volume to build structure and improve handling, commonly used to adjust feel, spread, and cost-in-use without acting as a primary active.

Benefits

Enhances powder flow for smoother, more consistent application.

Builds volume in formulas to improve texture without adding weight.

Reduces moisture absorption that leads to clumping during storage.

Who It's For

A quick guide for who this ingredient may suit (and who should be cautious).

Who May Benefit Who Should Avoid
Users of powder-based makeup seeking uniform blendability.
Those with rare sensitivities to polyurethane polymers.
Individuals preferring lightweight formulas with good structure.
Individuals preferring fully natural or polymer-free products.
People looking for stable products that resist caking over time.
Users experiencing issues with similar synthetic texturizers.

Safety Notes

  • Considered low hazard in cosmetic use by safety assessments.
  • Non-comedogenic, unlikely to clog pores.
