Retinol
Retinol (Vitamin A Alcohol, CAS:68-26-8) is the gold-standard anti-aging retinoid raw material. It exists as pale yellow crystalline powder, fat-soluble, converts to retinoic acid inside skin cells to activate collagen synthesis and accelerate keratin turnover. It delivers powerful anti-wrinkle, pore refining, light spot fading and skin tightening effects, widely used in high-end anti-aging serums, night creams, pore care and body firming lotions.
We supply 3 standard grades: 99% pure Retinol powder, 10%/20% oil-soluble Retinol stock liquid, microcapsule slow-release Retinol for sensitive skin lines. All batches adopt full low-temperature oxygen-isolated production to control peroxide value & oxidation impurities, fully compliant with CosIng, FDA, ISO22716, GMP, HALAL & KOSHER. Free samples and full COA/SDS documents provided.

Core Benefits & Functional Mechanism of Retinol
Retinol penetrates epidermis and converts into retinoic acid inside keratinocytes. Two core anti-aging pathways: 1. Activate fibroblast gene expression to boost collagen & elastin synthesis, fill fine lines and lift sagging skin; 2. Accelerate orderly keratin exfoliation, unclog pores, accelerate melanin metabolism to fade post-acne marks and photoaging pigmentation. Long-term use refines rough texture, shrinks enlarged pores and restores smooth translucent skin.
Retinol carries mild irritation risk for sensitive skin; we recommend compounding with panthenol, centella asiatica extract, niacinamide and squalane to soothe barrier irritation. Microcapsule encapsulated Retinol slows release to cut irritation for sensitive skin series. Avoid pairing with high-concentration acid ingredients to prevent over-stimulating skin.
- Boost collagen & elastin: fill dry lines, static wrinkles, improve sagging loose skin contour
- Speed up keratin turnover: dissolve blackheads, closed comedones, refine enlarged oily pores
- Fade light pigmentation: accelerate melanin shedding, fade sun spots, acne marks and dull yellow tone
- Smooth rough aging texture: improve chicken skin, uneven bumpy skin on face & body
- Sebum regulation: balance oily secretion, long-term control shine for combination & oily skin
- Multi-formula compatibility: pure powder, oil stock liquid, slow-release microcapsule 3 options for all anti-aging lines
Formulation Tip: Night skincare only, recommended dosage 0.1%-0.3% (retinol basis); finished products must use amber light-proof bottles, add BHT/Vitamin E antioxidant stabilizers; sensitive skin match centella & panthenol to reduce irritation.

Top Frequently Asked Questions about Retinol Powder
1. What is the CAS number, purity and specification of your Retinol Powder?
Our cosmetic-grade Retinol Powder is all-trans retinol (Vitamin A alcohol), CAS: 68-26-8, molecular formula C₂₀H₃₀O.
Standard purity: ≥98% / ≥99% verified by HPLC, pale yellow crystalline powder.
We add proprietary antioxidant stabilizer system inside powder to slow oxidation; full batch COA, HPLC chromatogram, isomer impurity test data are supplied.
Clear differentiation from Retinyl Acetate, Retinyl Palmitate powder (more stable ester derivatives with weaker activity).
2. What full safety & impurity testing is completed per batch?
Every batch conducts comprehensive tests:
Heavy metals (Pb, As, Cd, Hg), residual solvents, total isomer impurities (cis-retinol, anhydroretinol), peroxide value, microbial indicators (TPC, yeast & mold, E.Coli, Pseudomonas aeruginosa, Salmonella), heavy metal catalytic oxidation risk screening.
Comply with EU SCCS, CosIng, FDA, ISO22716, GMP cosmetic raw material standards. Complete test documents support global cosmetic registration, third-party factory audits and customs clearance.
3. What is the recommended dosage, applicable formulations & pH tolerance range?
Global regulatory upper limit for finished skincare: 0.3% retinol in leave-on facial products (follow local regional rules).
Typical formulation dosage: 0.05%–0.3% for anti-aging serums, firming creams, acne treatment gels, eye anti-wrinkle creams.
Stable pH window: 5.0–7.0; avoid strong acid, strong alkali,
long-term UV light & high temperature during production/storage, which trigger isomerization and activity loss.
Compatible with tocopherol, centella asiatica extract, hyaluronic acid, panthenol to reduce irritation; incompatible with metal ions, strong oxidants. Pre-formulation stability testing is mandatory.
4. Extremely critical: Shelf life, storage & packaging requirements
Retinol is highly sensitive to light, oxygen, heat and metal ions:
Unopened sealed powder under 2–8°C cold dark storage: 24 months shelf life
Room temperature sealed storage: only 6–12 months, activity declines rapidly
Liquid retinol formulations: 3–8 months (depends on inert gas filling & antioxidant system)
Packaging must use light-proof aluminum foil bags / opaque metal drums with desiccant, filled with nitrogen/argon inert gas to isolate oxygen.
After opening, seal tightly immediately, finish use within 1 month under refrigeration to prevent oxidation, yellowing and efficacy attenuation.
5. What’s the core difference between Retinol Powder, Retinyl Acetate and Retinyl Palmitate Powder?
Retinol (Vitamin A Alcohol Powder): Highest biological activity, direct skin efficacy; extremely unstable, strict cold storage required, high irritation risk for sensitive skin, used in high-performance anti-aging professional skincare.
Retinyl Acetate: Ester derivative, medium stability, moderate activity, balanced cost & performance.
Retinyl Palmitate: Most stable, lowest irritation, weakest whitening/anti-aging activity, mass-market daily skincare raw material.
Three items have different CAS, activity intensity, storage requirements and cannot substitute each other directly in formulas.
6. Is Retinol Powder vegan, allergen-free & available with HALAL/KOSHER certificates?
Our standard retinol powder is synthetic, vegan, cruelty-free, non-GMO, gluten-free, no parabens or artificial fragrances.
HALAL, KOSHER compliance documents can be provided for export brands upon request.
Retinol may trigger dryness, peeling or redness on sensitive skin at high concentrations; patch testing is compulsory for sensitive skin finished formulas.
7. What is MOQ, packaging and delivery timeline?
Sample MOQ: 5g for formulation stability testing
Bulk export packaging: 1kg / 5kg light-proof aluminum foil bags, 25kg opaque metal drums with inert gas filling
In-stock standard powder orders: 3–7 working days delivery (cold chain transport available)
Custom stabilized retinol liquid / microencapsulated retinol
powder: 7–14 working days production lead time
Long-term framework bulk orders supported with consistent
batch purity & stable activity retention.
8. Can I get free test samples and full compliance documents?
Qualified bulk buyers can apply for 5g free samples for compatibility & stability trials.
We supply batch COA, SDS/MSDS, HPLC test reports, GMP/ISO22716 certificates, full batch traceability records, SCCS safety evaluation materials, supporting REACH, CPNPF and overseas cosmetic filing & import clearance.
9. Why does retinol powder turn yellow/brown and lose efficacy? How to avoid it?
Discoloration and activity loss are mainly caused by three factors:
UV/light exposure, oxygen contact, high temperature + metal ion contamination.
Solutions:
Adopt nitrogen-filled inert gas sealed packaging; store at 2–8°C dark cold warehouse
Add tocopherol/BHT antioxidant in finished formulas
Use opaque raw material storage tanks, avoid stainless steel metal containers during production
Control workshop temperature below 30°C, shorten open-air operation time
We provide stability acceleration test reports for reference.
10. Do you support factory audit, third-party independent testing & customized stabilized grades?
Our production line operates under GMP & ISO22716 clean cosmetic workshop standards, with full temperature-controlled cold storage warehouse for retinol stock.
We welcome on-site factory audits, third-party independent lab testing; customized stabilized retinol powder with enhanced antioxidant system and microencapsulated retinol are available to improve formula stability.
