Moisture support
Explore COS in humectant and moisture-retention systems for skin-conditioning formulations.
Luma Ingredients
A water-soluble marine-derived ingredient for skincare and personal-care formulation development.
We supply cosmetic-grade COS with a defined molecular-weight profile and product-specific quality data. Explore it as a functional ingredient for creams, lotions, serums and daily-care formulations.
COS content ≥90% · Molecular weight ≤1,600 Da · Light yellow powderChitooligosaccharide (COS) is a low-molecular-weight ingredient derived from chitin. Supplier materials describe this grade as produced through enzymatic hydrolysis and membrane separation, yielding a water-soluble powder for cosmetic and daily-care product development.
Its molecular structure and film-forming behavior make COS an ingredient of interest for moisturization, skin-conditioning and protective-film concepts. We work with formulators to review the product specification, formulation fit and technical documentation for each project.
Explore functional roles that can be evaluated in the context of the complete formulation and intended product.
Explore COS in humectant and moisture-retention systems for skin-conditioning formulations.
Its film-forming properties can support protective-film concepts in topical product systems.
Evaluate COS as a conditioning ingredient in products designed for a smooth, comfortable skin feel.
Antioxidant and antimicrobial properties are active areas of ingredient research; performance depends on the formulation and test conditions.
Our cosmetic-grade COS can be evaluated across leave-on and rinse-off product concepts.
Explore COS in moisturizers, facial creams, lotions and serum systems where water solubility and skin-conditioning functionality are relevant.
Evaluate COS in toothpaste and mouth-rinse concepts, subject to product formulation, ingredient grade and target-market requirements.
Consider COS in shampoo, hand wash and other cleansing formulations. Compatibility and performance should be confirmed in the finished formula.
We use chitin sourced from deep-sea snow crab and apply enzymatic hydrolysis followed by membrane separation to produce low-molecular-weight COS. The process is designed to deliver a water-soluble ingredient with a clear, measurable product profile.
Each lot is evaluated against product specifications, including COS content, moisture, ash, pH, insoluble matter and microbiological criteria. Request the current batch COA and supporting technical documents for your review.

Cosmetic ingredient naming, permitted use, safety assessment, labelling and claims vary by destination market and finished-product category. We provide ingredient specifications and available technical documents to support your evaluation; final formula validation and regulatory review should be completed for the intended market.
Published research has investigated chitooligosaccharides and related chitosan materials in cosmetic and skin-care contexts. Study results depend on molecular weight, material type, concentration and formulation design.
