FAQ

1. What industries are Lanneret's sodium alginate products mainly used in?

Answer: Qingdao Lanneret Biochemical's sodium alginate series products have a wide range of applications, covering food, textile dyeing and printing, ceramics, cosmetics, organic agriculture, building materials, dentistry, medicine, welding and other fields. Customized product solutions can be provided according to the needs of different industries.

2. What is the difference between food-grade sodium alginate and ordinary sodium alginate?

Answer: Food-grade sodium alginate is a natural water-soluble dietary fiber extracted from brown algae, which meets food-grade safety standards. It has gelation, thickening, film-forming and other properties, and has physiological functions such as assisting in lowering blood pressure and regulating blood lipids. Ordinary sodium alginate (such as textile grade and coating grade) focuses on industrial application performance, and its purity and safety indicators are designed for industrial scenarios, so it cannot be directly used in food processing.

3. What are the different application scenarios of reactive dyeing paste and disperse dyeing paste in textile grade sodium alginate?

Answer: Reactive dyeing paste is suitable for reactive dye printing processes. Due to its anionic nature, it generates electrostatic repulsion with reactive dyes, promoting dye uptake and avoiding problems such as poor fastness and bleeding. Disperse dyeing paste uses low-viscosity sodium alginate, which adapts to the hydrophobic characteristics of synthetic fibers. It can prepare high-solid-content color pastes to ensure uniform and clear printing effects of disperse dyes.

4. What roles do cosmetic-grade sodium alginate play in mask and cream products respectively?

Answer: Cosmetic-grade sodium alginate for masks (model LN50) has strong film-forming properties and good tear resistance. It is rich in natural nutrients, which can moisturize and lock water, shrink pores, reduce inflammation and inhibit bacteria. The special model LN10 for creams has excellent thickening and emulsifying properties, which can stabilize the oil-water system, increase product consistency, and at the same time enhance skin moisture retention and elasticity, improving skin texture.

5. What is the minimum order quantity (MOQ) for purchasing Lanneret's sodium alginate products, and what is the delivery time?

Answer: The minimum order quantity (MOQ) can be flexibly adjusted according to product models and order requirements, with a conventional MOQ of 1 ton. Regarding delivery time, domestic orders usually take 7-15 working days, and export orders take 20-45 working days depending on the destination. The company's annual production capacity of 10,000 tons can ensure fast supply.

6. What are the core application scenarios of ultra-high viscosity and ultra-low viscosity sodium alginate?

Answer: Ultra-high viscosity sodium alginate (viscosity 2000-10000cps) is suitable for products requiring extremely high viscosity, such as toothpaste and jam. An addition amount of only 0.5-1% can achieve excellent thickening and gelation effects. Ultra-low viscosity sodium alginate (viscosity as low as 3cps) retains complete biological activity and is mainly used in health products, medical capsules, plasma substitutes, cigarette filter beads and other fields.

7. What international certifications have Lanneret's sodium alginate products obtained?

Answer: Qingdao Lanneret Biochemical has established a complete quality control system. Its products have obtained multiple international certifications such as ISO, food-grade FDA, and cosmetic-grade GMP, complying with import standards of more than 50 countries including Europe, North America, and South America, with guaranteed quality and safety.

8. What are the performance differences between potassium alginate and sodium alginate?

Answer: Potassium alginate is prepared by reacting alginic acid with potassium carbonate. It has better hydrophilicity, fluidity and gel strength than sodium alginate, and has more stable molding effect under the same conditions. Sodium alginate has a wider application range and more cost-effective price. The two can be selected according to specific uses (such as dental models, welding electrodes, cosmetics, etc.).

9. When using sodium alginate for bursting beads, how to control the hardness and taste of the outer skin?

Answer: First, select sodium alginate with a viscosity of 400-500mpa.s to prepare an outer skin glue solution of about 0.7%. If a stronger outer skin is needed, quickly calcify the bursting beads in a 3-5% calcium chloride solution, then rinse with clean water to keep the surface smooth and not rough. At the same time, it is necessary to accurately control the content of citric acid and calcium salts in the inner core, as excessive or insufficient acid or calcium will affect molding and taste.

10. Can Lanneret Biochemical provide customized sodium alginate products?

Answer: Yes. The company has a professional R&D team and can customize the production of various sodium alginate products such as textile grade, food grade, cosmetic grade, and industrial grade according to customers' personalized needs such as viscosity, mesh size, purity, and application scenarios. It also provides technical support and sample testing services.
