2. Fragrance Range
Standard fragrances: COCO perfume, lavender, white tea, rose, bluebell, woody, and fresh ocean.
Custom fragrances: IN4LL Synesthesia Factor series (including orange blossom, deep red rose, and honeysuckle); bespoke fragrance blending is available.
3. Blending Recommendation (Industry Standard): Use free fragrance together with microencapsulated fragrance.
(1) Free fragrance dosage: 0.1%-0.3%, providing fragrance on opening and during washing.
(2) Microencapsulated fragrance dosage: 0.02%-0.05%, providing long-lasting fragrance release through friction on dry fabrics.
Standalone use: Scent booster beads can use microencapsulated fragrance alone, without free fragrance.
Addition: Add as the final ingredient at low temperature throughout processing (≤45°C). Avoid exposure to high temperatures, strong acids or alkalis, and strong oxidizing agents.
4. Fragrance-Lasting Performance (Tested on 100% Cotton Fabric)
(1) During wear: 7-14 days, with a pronounced fragrance burst when rubbed.
(2) Stationary storage in a wardrobe: 20-30 days; a light fragrance remains detectable when the fabric is rubbed.
(3) Wash durability: Fragrance remains noticeable after 3-5 standard machine washes, with a light residual fragrance after 6-8 washes.
