Application
1. Dermatology / Skincare
Acne Treatment: Inhibits Cutibacterium acnes, regulates follicular keratinization, and exerts anti-inflammatory effects. Recommended by Chinese Guidelines (15% gel / 20% cream).
Whitening & Mark Fading: Selectively inhibits tyrosinase in abnormal melanocytes to fade acne marks, PIH, and melasma with lower irritation than tretinoin.
Oil Control & Soothing: Inhibits 5α-reductase to reduce sebum. Ideal for oily skin and rosacea care.
Common Dosage Forms: Gels, creams, moisturizers, serums, and masks.
10%: Daily skincare (suitable for sensitive skin)
15%: Mainstay for acne treatment
20%: Pharmaceutical grade (requires tolerance building)
2. Industrial Chemical Sector
Plasticizers: Synthesis of DOZ, Diisooctyl Azelate, etc. Used in PVC and rubber for heat/cold resistance.
Lubricants / Synthetic Oils: Components for precision instruments and aviation hydraulic fluids.
Coatings / Resins: Modified polyesters and alkyd resins for flexibility and weatherability.
3. Other Applications
Feed additives, electroplating brighteners, polymer crosslinking agents, etc.
Application Areas
1. Hair Care Industry (Core Application)
Cold Wave Lotions: Core reducing agent for permanent curling.
Straightening Creams: Cleaves disulfide bonds to soften hair for permanent straightening.
Depilatory Products: Softens body hair keratin for easy removal.
Recommended Concentration: 5%–15% (Perming); 2%–8% (Depilatory).
2. Industrial & Other Fields
Metal Corrosion Inhibition: Forms protective FeS film in high-temp environments (140–200℃).
Chemical Analysis: Masking/reducing agent for iron, aluminum, silver, and tin determination.
Material Modification: Thiolating agent for adsorption materials and functional polymers.
Electronic Cleaning: Auxiliary agent for metal surface treatment.
