CAS No.: 9005-32-7
EINECS No.: 232-679-6
Source: Derived from high-quality natural kelp and wild brown seaweed, adopting low-temperature physical extraction, biological purification, multi-stage impurity removal, ion replacement and sterile spray drying technology.
Grade: Cosmetic Premium Natural Grade (High-Purity Low-Irritation Special Grade, Non-Deliquescent High-Stability Type for Sensitive Skin & Long-Shelf Formulas)
Appearance: Uniform white fine powder, pure and impurity-free, odorless and non-toxic.
MOQ (Minimum Order Quantity): 25KG
Solubility: Rapidly swells and dissolves completely in cold and warm water to form uniform transparent viscous colloid without high-temperature heating. Insoluble in ethanol and other conventional organic solvents. In water-based cosmetic systems, it integrates mild thickening, flexible gelling, efficient suspension and long-term stabilization. The colloid is smooth, refreshing and non-sticky, with neutral and mild pH value, strong system compatibility, and more stable performance than ordinary alginate products.
Storage Condition: Sealed and stored in dry, cool and ventilated dust-free warehouse. Although it has non-deliquescent advantages, still avoid extreme humid environment, high temperature and direct sunlight. Keep tightly sealed after opening to maintain powder solubility, gelling activity and long-term stability.
Shelf Life: 24 Months

Cosmetic Grade Potassium Alginate Powder-CAS 9005-32-7
Cosmetic Grade Potassium Alginate is a high-purity, low-irritation and high-stability natural brown seaweed functional raw material. Refined via pure physical ion replacement and low-temperature extraction technology, it retains high-activity natural alginate polysaccharides.
Different from sodium alginate, carrageenan and pectin, it has the unique advantages of non-deliquescent powder, neutral mild pH and ultra-low skin irritation.
It can mildly thicken and shape cosmetic formulas, form flexible and smooth gel texture without hard brittleness and sticky residue, and effectively improve the long-term stability of water-based systems.
Its natural seaweed moisturizing factors can lock skin moisture for a long time, soothe dry and sensitive skin, and repair rough skin texture. With excellent storage stability and sensitive skin compatibility, it is an irreplaceable core raw material for high-end long-shelf-life and mild clean beauty cosmetics.
Key Benefits
• Non-Deliquescent Powder, Super Storage Stability: Unique potassium ion molecular structure, effectively solving the moisture absorption and caking problems of ordinary alginate powder. No special moisture-proof storage required, stable powder activity, convenient transportation and long-term storage.
• Ultra-Low Irritation, Sensitive Skin Friendly: Neutral mild pH value, no residual alkaline components, lower skin irritation than sodium alginate. High biocompatibility, perfectly suitable for sensitive skin, fragile skin and zero-addition clean beauty formulas.
• Natural Brown Seaweed Source, Pure & Safe: Derived from high-quality wild brown seaweed, pure physical purification without chemical modification and harmful residues. Non-toxic and non-sensitizing, fully compliant with international cosmetic safety standards.
• Mild Thickening & Flexible Texture Shaping: Provides mild and uniform thickening effect, forms flexible and smooth gel texture, avoids hard and brittle gel defects, brings delicate and refreshing non-sticky skin feeling.
• Long-Lasting Formula Stability & Anti-Demulsification: Excellent rheological stability, effectively inhibits formula delamination, water separation and particle precipitation. Stable texture and viscosity throughout the shelf life, greatly extending product service life.
• Cold Water Soluble & Wide Compatibility: Fast cold water dissolution, no high-temperature heating required, protecting heat-sensitive active ingredients. Fully compatible with all water-based cosmetic systems, stable batch performance for mass production.
Applications
• Sensitive Skin Mild Skin Care Series: Core low-irritation thickening and stabilizing raw material for sensitive and fragile skin formulas, reducing formula irritation and improving skin comfort.
• Long-Shelf-Life Cosmetic Products: Ideal raw material for long-term storage skin care products, relying on super storage stability to maintain uniform texture and stable efficacy throughout the shelf life.
• Transparent Gel & Light Texture Skin Care: Used in transparent moisturizing gel, soothing jelly and lightweight skin care products, creating smooth, delicate and high-grade refreshing texture.
• Heat-Sensitive Active Formula: Suitable for essence, lotion and gel containing heat-sensitive ingredients, cold water dissolving process avoids high-temperature damage to active substances and retains maximum efficacy.
• Suspended Particle Functional Cosmetics: Stably suspends plant fine particles, microcapsules and functional additives, realizing long-term uniform suspension without precipitation and improving product appearance grade.
• Zero-Addition Clean Beauty Products: Pure natural seaweed raw material with ultra-mild properties, conforming to clean beauty safety concept, suitable for high-end mild daily skin care products.

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of Cosmetic Grade Potassium Alginate?
A1: The standard MOQ is 25KG, support sample orders for formula testing and trial production, and support customized viscosity specifications.
• Q2: What is the difference between Potassium Alginate and Sodium Alginate?
A2: Potassium Alginate adopts potassium ion replacement structure, featuring non-deliquescent powder, milder neutral pH and lower skin irritation. It has better storage stability and sensitive skin compatibility. Sodium alginate is slightly alkaline, easy to absorb moisture, and has relatively higher irritation. Potassium alginate is more suitable for long-shelf-life and sensitive skin high-end formulas.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Sensitive skin moisturizing gel & jelly: 0.7%–2.8%; Long-shelf-life lotion & toner: 0.2%–0.8%; Suspended particle skin care: 0.4%–1.5%; Heat-sensitive essence formula: 0.3%–1.0%, adjustable according to texture and stability requirements.
• Q4: Is Potassium Alginate suitable for sensitive skin clean beauty?
A4: Absolutely yes. It has neutral mild pH, ultra-low irritation, pure natural seaweed source and zero chemical residues. It can soothe and moisturize fragile skin while stabilizing formulas, which is the ideal raw material for clean beauty and sensitive skin care products.
• Q5: What formula systems is Potassium Alginate compatible with?
A5: Fully compatible with all water-based cosmetic systems including toner, essence, gel, lotion and cream. Stably compounded with heat-sensitive active ingredients, plant extracts and various functional additives without demulsification or precipitation.
• Q6: What are the formula usage notes?
A6: Disperse evenly in cold water for full swelling to exert optimal thickening and stabilizing effects; suitable for neutral and weak acid systems with the best stability; avoid strong alkaline environment to maintain mild formula attributes.
• Q7: Do you support stable mass supply and customized specifications?
A7: Strictly control purity, viscosity and pH indicators to ensure consistent batch mildness and stability. Support customized technical specifications. Sufficient inventory all year round supports long-term bulk orders and professional formula technical guidance.
