What does OEKO-TEX Standard 100 mean?
OEKO-TEX Standard 100 is an independent certification that tests textiles against a list of known harmful substances. A certified fabric has passed these tests. It does not make any claims about skin benefit or therapeutic effect — it is a materials safety certification. Full details at oeko-tex.com.
What is the hyaluronic acid infusion and how is it applied?
Hyaluronic acid is infused into the mulberry silk fibres using a microcapsulation process during manufacture — the compound is encapsulated and bonded to the fibre structure. The specific claims for skin effect from this treatment are the responsibility of Sleep In Beauty; no efficacy claims are made here. For the manufacturer's description of the technology, refer to the Sleep In Beauty product documentation.
What does 22 momme mean?
Momme (mm) is the weight measurement used for silk fabrics. Higher momme indicates a heavier, more substantial fabric. 22 momme is considered a mid-to-high weight for silk pillowcases — heavier than most entry-level silk and suitable for regular use.
How do I wash a silk pillowcase?
Silk requires gentle care. Hand wash in cool water with a mild detergent, or machine wash on a delicate cycle inside a mesh laundry bag. Do not wring, bleach, or tumble dry — lay flat or hang to dry. For specific care guidance on the hyaluronic acid–infused fabric, refer to the Sleep In Beauty care instructions.
What size is this pillowcase?
The pillowcase measures 50×75cm, described by Sleep In Beauty as a standard queen size. Check this against your pillow dimensions before purchasing.
