Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of Cosmetic Grade Iron Oxide Red?
A1: The standard MOQ is 25KG, and sample orders are supported for formula color testing and trial production.
• Q2: Is this pigment safe for lip and eye makeup?
A2: Yes. This cosmetic grade iron oxide red adopts high-purity purification process, ultra-low heavy metal, no harmful impurities. It complies with cosmetic safety regulations for eye and lip contact, safe for multi-area facial makeup.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Blush & cheek tint: 2%–12%; Lip products: 1%–8%; Eye makeup: 0.5%–5%; Tinted skincare: 0.3%–3%; Contour makeup: 1%–6%, adjustable according to target color saturation and tinting demand.
• Q4: What is the advantage of inorganic iron oxide red over organic red pigment?
A4: Iron oxide red features super lightfastness, no fading, stable color tone and high safety. Organic red pigments are easy to fade, discolor and have poor weather resistance. Inorganic iron oxide has stable crystal structure, long color retention, no irritation, and is more suitable for long-lasting cosmetic formulas.
• Q5: Will the powder agglomerate or float color during production?
A5: No. Our ultra-fine graded iron oxide red has excellent dispersion. It can be quickly and evenly dispersed in powder, oil and emulsion systems through conventional stirring, no agglomeration, floating color or color stratification.
• Q6: What are the formula matching notes?
A6: Grind and disperse adequately during batching for better color uniformity; match with other iron oxide pigments (yellow, black) for customized color tones; avoid excessive high dosage to prevent overly dark color; store finished products in moisture-proof sealing to maintain color stability.
• Q7: Do you support customized color and stable mass supply?
A7: Stable color difference control for each batch, support customized particle size and color saturation processing. Sufficient inventory all year round supports long-term bulk orders and OEM formula color matching services.
