HERSONCARE Slow Released Retinol Powder – hydroxypropyl cyclodextrin-encapsulated retinol, 310,000–330,000 IU/g.
HERSONCARE Slow Released Retinol Powder is an encapsulated vitamin A raw material built on hydroxypropyl cyclodextrin inclusion technology. Retinol is one of the most effective anti-aging actives and also one of the most difficult to formulate: it degrades under light, heat, and metal ions, and at effective doses it produces stinging and flaking that limit consumer tolerance. Encapsulation is not an enhancement here — it is the condition that makes retinol usable in a stable, marketable formula.
The product carries 310,000–330,000 IU/g retinol (10% active) in a yellow crystalline powder, INCI Hydroxypropyl Cyclodextrin, Retinol, CAS 5979-23-7. The cyclodextrin host shields the molecule from oxidative degradation while controlling release onto the skin, extending efficacy and reducing irritation at the same time. The powder is water-dispersible, allowing direct incorporation into gel, serum, emulsion, and cream systems without solvent carriers. HERSONCARE supplies this grade within a Cosmetic Raw Materials portfolio that also includes Cosmetic Azelaic Acid, Azelaic Acid for Oil Dispersion, and D-delta Mixed Tocopherols — allowing a complete brightening platform to be sourced from one supply chain.
INCI: Hydroxypropyl Cyclodextrin, Retinol. CAS No.: 5979-23-7. Appearance: yellow crystalline powder. Model No.: HCP-022. Retinol content: 310,000–330,000 IU/g (10% active).
Loss on drying: ≤2.0%, protecting the complex from moisture-driven degradation. Heavy metals: ≤0.002%. Solubility: dispersible in water. Microbiological: total plate count ≤500 cfu/g; yeast and mold <100 cfu/g; E. coli, Salmonella, and Pseudomonas aeruginosa negative.
Total retinol content alone does not describe behavior. Three values must be read together: retinol content in IU/g (how much active is present), encapsulation efficiency (how much is genuinely bound within the cyclodextrin host), and free retinol percentage (the unencapsulated fraction, which drives irritation and degradation). A product can report 10% retinol and still behave poorly if a significant fraction is unencapsulated.
Reference images cover powder appearance, water dispersion behavior, and finished formulation examples. A production walkthrough covering inclusion complex formation, drying, and QA release is available on request.
The inclusion complex is a defined chemical entity with its own INCI and CAS reference, not a marketing description. The cyclodextrin cavity physically hosts the retinol molecule, shielding the sensitive double-bond system from light, heat, and metal-ion catalyzed oxidation. This is why carrier identity matters when comparing suppliers.
Free retinol contacts the skin in a single bolus, which is why conventional retinol flakes at effective doses. The complex releases retinol gradually as it dissociates at the skin surface, flattening the concentration peak and allowing effective doses with lower irritation. This makes the grade suitable for sensitive skin and retinol-naïve consumers entering an anti-aging regimen.
Liquid retinol requires solubilizers that complicate formulation and can themselves irritate. The powder disperses directly in water, simplifying gel, serum, and emulsion development and removing a class of excipients from the formula.
Beyond surface exfoliation, retinol stimulates epidermal proliferation, supports collagen synthesis, strengthens the barrier, and increases glycosaminoglycan content. The encapsulated form delivers these activities with a tolerability profile that supports daily long-term use.
Sustained release supports continuous benefit with minimal irritation, addressing fine lines, wrinkles, and uneven tone.
The periocular area tolerates free retinol poorly. Slow-release encapsulation supports eye creams targeting crow's feet, dark circles, and puffiness.
The cyclodextrin complex improves delivery in concentrated serums while controlled release limits the irritation of high-strength retinol.
Retinol and azelaic acid address overlapping but distinct pathways in tone and texture. Formulating slow-release retinol alongside Cosmetic Azelaic Acid or Azelaic Acid for Oil Dispersion, with D-delta Mixed Tocopherols for oxidative protection, supports a complete brightening regimen from one ingredient source.
Encapsulation reduces potency loss across shelf life and lowers the risk of reformulation cycles caused by color drift or activity decline.
Sustained release flattens the concentration peak at the skin surface, reducing stinging and flaking. Higher compliance translates into better perceived results.
Encapsulated retinol supports tolerability and sensitive-skin claims that free retinol cannot credibly make, enabling higher price positioning.
