Cosmetic Grade Calcium Alginate Powder(CAS 9005-35-0)
Product Name: Calcium Alginate
INCI Name: Calcium Alginate
Alias: Natural Brown Seaweed Calcium Alginate, Cosmetic Hard Elastic Gel Agent, Non-Crosslinking Film-Forming Stabilizer, Non-Sticky Texture Thickener, High-Rigidity Rheology Modifier, Long-Lasting Shaping Seaweed Raw Material
CAS No.: 9005-35-0
EINECS No.: 232-678-0
Source: Derived from high-quality natural kelp and brown seaweed, adopting low-temperature physical extraction, biological purification, calcium ion directional replacement, multi-stage fine impurity removal and sterile spray drying technology. Zero chemical modification, zero harmful residues, completely retaining natural brown seaweed polysaccharide active ingredients.
Grade: Cosmetic Premium Natural Grade (High-Purity Hard Elastic Special Grade, Pre-Crosslinked Non-Sticky Type for Stereo Shaping & Non-Return Viscosity Formulas)
Appearance: Uniform white fine powder, pure and impurity-free, odorless and non-toxic. The powder is loose, dry and uniform with excellent anti-caking and non-deliquescent performance. It has moderate cold water solubility and rapid uniform swelling without agglomeration. After dissolution and hydration, it forms rigid, tough and smooth elastic colloid with strong stereoscopic shaping power, no sticky residue and no returning viscosity. The solution system is stable, with uniform texture and no delamination or precipitation after long-term placement.
MOQ (Minimum Order Quantity): 25KG
Solubility: It can swell and hydrate rapidly in cold and warm water to form uniform tough elastic colloid without high-temperature heating and additional calcium ion cross-linking. Insoluble in ethanol and other conventional organic solvents. In water-based cosmetic systems, it integrates rigid shaping, tough film-forming, anti-sticky stabilization and uniform suspension. The gel is firm and elastic with strong stereoscopic sense, completely solving the common problems of soft collapse and returning stickiness of sodium/potassium alginate gels.
Storage Condition: Sealed and stored in dry, cool and ventilated dust-free warehouse, avoid humid environment, high temperature and direct sunlight to prevent moisture absorption and agglomeration. Keep tightly sealed after opening to maintain powder hydration activity, gel rigidity and long-term shaping stability.
Shelf Life: 24 Months

Cosmetic Grade Calcium Alginate Powder(CAS 9005-35-0)
Cosmetic Grade Calcium Alginate is a high-rigidity, non-sticky and self-gelling natural brown seaweed functional raw material. Refined via pure physical calcium ion pre-crosslinking and low-temperature extraction technology, it retains high-activity natural alginate polysaccharides.
Different from sodium alginate and potassium alginate which rely on external calcium ions for molding, calcium alginate adopts in-situ calcium saturation crosslinking structure, featuring one-step gelling without additives, hard elastic stereoscopic texture and zero returning stickiness.
It can build firm and delicate product texture for cosmetics, effectively solve the defects of soft collapse, sagging and post-stickiness of ordinary alginate gels, and significantly improve formula long-term stability.
Its dense seaweed polysaccharide film can stably lock skin moisture, smooth rough texture, and bring lasting refreshing non-greasy skin feeling. With ultra-mild safety and unique shaping advantages, it is an irreplaceable core raw material for high-end three-dimensional textured and non-sticky clean beauty cosmetics.
Key Benefits
• Self-Gelling Without Crosslinking, Simple Process: Pre-saturated calcium ion structure, no need to add calcium salt crosslinking agent additionally. One-step hydration molding simplifies production process, avoids formula instability caused by uneven calcium reaction, and improves production efficiency.
• Hard Elastic Stereo Shaping, Anti-Collapse & Anti-Sag: Unique high-rigidity gel attribute, the formed gel is firm and bouncy with strong stereoscopic sense. Effectively solves the problems of soft texture, easy collapse and sagging of sodium/potassium alginate gels, shaping high-grade three-dimensional texture.
• Zero Returning Stickiness, Long-Lasting Refreshing Feeling: Inherent non-sticky formula characteristics, no residual stickiness on the skin, no post-return viscosity after drying. Maintains long-term refreshing and non-greasy skin feeling, perfectly suitable for high-demand non-sticky cosmetic formulas.
• Natural Brown Seaweed Source, Ultra-Mild Safe: Derived from high-quality wild brown seaweed, pure physical purification without chemical modification and harmful residues. Non-toxic and non-sensitizing, high biocompatibility, suitable for sensitive skin and zero-addition clean beauty formulas.
• Dense Film-Forming & Stable Moisturizing: Forms dense and tough breathable protective film on skin surface, stably locks moisture, relieves dry and rough skin, improves skin barrier toughness, and avoids moisture loss caused by thin and fragile film.
• High System Stability & Wide Compatibility: Excellent anti-demulsification, anti-delamination and anti-precipitation performance, stable texture throughout shelf life. Fully compatible with all water-based cosmetic systems, stable batch performance for industrial mass production.
Applications
• 3D Stereo Shaping Jelly Mask & Gel: Exclusive raw material for high-stereoscopic jelly mask and firm transparent gel, creating bouncy, firm and non-deformable texture that ordinary alginate cannot achieve.
• Non-Sticky High-Grade Skin Care Products: Core stabilizer for refreshing non-greasy lotion, matte moisturizing gel and daily clean beauty products, solving the pain point of returning stickiness of traditional thickeners.
• Long-Shelf-Life Suspension Functional Formula: Stably suspends plant fine particles, microcapsules and functional active ingredients, maintains uniform product texture for a long time, and avoids soft collapse and precipitation during storage.
• Exfoliating & Cleaning Gel Series: Applied in transparent exfoliating gel and deep cleaning gel, optimizing firm and smooth texture, improving cleaning experience without sticky residue after washing.
• Heat-Sensitive Mild Beauty Formulas: Adapts cold water dissolving process, no high-temperature heating required, protects heat-sensitive active ingredients, and retains maximum efficacy of skin care products.
• Sensitive Skin Clean Beauty Products: Ultra-mild zero-irritation natural seaweed raw material, conforming to clean beauty safety concept, suitable for long-term mild skin care and high-end non-sticky cosmetic development.
