Hydroxypropyl Cyclodextrin

Product Description

As a leading manufacturer, we provide high-purity Hydroxypropyl Cyclodextrin (HP-β-CD) directly from our specialized production facility to the global cosmetic industry. This ingredient functions as a superior molecular "cage" through its unique hydrophobic cavity, which encapsulates lipophilic active molecules to dramatically improve their solubility and bioavailability in aqueous formulations. With the increasing market demand for "clean label" and high-performance skin care, this stabilizer has become an essential tool for formulators seeking to protect sensitive actives like Retinol or Fragrances from oxidation and UV degradation.

Product Specification

• INCI Name: Hydroxypropyl Cyclodextrin
• CAS No.: 128446-35-5 / 94035-02-6
• Appearance: White crystalline powder
• Purity (Assay): ≥ 98.0%
• Molar Substitution: 0.40 – 1.50
• Loss on Drying: ≤ 5.0%
• Heavy Metals: ≤ 10 ppm
• Solubility: Highly soluble in water (> 50g/100ml at 25°C)

Key Benefits & Applications

• Enhanced Solubility: Transforms poorly water-soluble actives into stable aqueous solutions, allowing for clearer and more effective formulations.
• Controlled Release: Regulates the Dermal Penetration rate of encapsulated ingredients, reducing potential irritation while extending the efficacy period.
• Stability Improvement: Protects sensitive compounds from Tyrosinase-mediated oxidation, thermal degradation, and light-induced breakdown.
• Odor Masking: Effectively traps volatile off-notes of botanical extracts or chemical actives to improve the sensory profile of the final product.
• Versatile Application: Ideal for high-end serums, sunscreens, deodorants, and anti-aging emulsions.

Formulation Guidelines

• Recommended Usage: 0.5% – 5.0% depending on the concentration of the guest molecule to be encapsulated.
• Processing: Dissolve in the water phase at room temperature or slightly elevated temperatures (up to 60°C). For encapsulation, premix with the lipophilic active before adding to the aqueous phase.
• pH Stability: Stable across a wide pH range (pH 3.0 – 10.0), making it compatible with most cosmetic systems.
• Synergy: Combine with Retinol for enhanced stability and reduced skin irritation through molecular encapsulation.
