What is Algin Acid?

Alginic Acid is a polysaccharide compound that occurs naturally in the cell walls of certain species of macroalgae, especially brown algae such as kelp and macroalgae. Its chemical structure is mainly composed of two uronic acid units – β-D-mannuronic acid (M) and α-L-guluronic acid (G). These units are formed through β-1,4-glycoside Bonded to form a linear copolymer.

Algin Acid Uses

Food industry: As a food additive, alginic acid is widely used in various foods due to its excellent thickening, stabilizing and gelling properties. It can increase the viscosity of food, improve the taste and structural stability of ice cream, yogurt, jam, etc., and can also serve as an emulsifier and suspending agent to maintain uniform distribution of food ingredients.

Pharmaceutical field: In the pharmaceutical industry, alginic acid and its derivatives (such as sodium alginate) are used as carriers in drug delivery systems, which can control the release rate of drugs and achieve sustained release or targeted drug delivery. In addition, it can be used to make forming agents, adhesives for tablets, and as a dental mold material in oral care products.

Cosmetics industry: In personal care and cosmetics, alginic acid is used as a natural moisturizer and skin conditioner to help the skin retain moisture and improve dryness, while the light film it forms also helps protect the skin from external irritants.

Agriculture: As a biostimulant and soil conditioner, alginic acid can promote plant root growth, enhance crop stress resistance, improve soil water retention capacity and fertility, and promote the effective use of nutrients.

Water treatment: In the field of environmental protection, alginic acid can be used as a natural flocculant for water clarification and sewage treatment, effectively removing suspended solids and some heavy metal ions in the water and improving water quality.

Biotechnology: As a gel carrier in bioreactors, alginic acid can immobilize enzymes and microbial cells and be used in biocatalysis and bioconversion processes to improve production efficiency and product purity.

Textile and papermaking: In the textile and papermaking industry, alginic acid is used as a sizing agent, softener and reinforcing agent to improve fiber processing properties and the quality of the final product.

Prominent Applications of Alginic Acid in Makeup

Moisturizer: Alginic Acid has excellent hygroscopicity and can absorb moisture from the surrounding environment and lock in moisture, thereby increasing the skin’s moisture content, reducing dryness, and improving the skin’s hydration and elasticity. As a natural moisturizing ingredient, it is suitable for use in various moisturizing cosmetics such as creams, lotions, essences and masks.

Skin feel adjustment: In cosmetic formulas, Alginic Acid can form a thin protective film, improve the spreadability and touch of the product on the skin, and give the skin a silky feeling without affecting the normal breathing of the skin.

Stabilizer and suspending agent: Due to its excellent colloidal properties, Alginic Acid can help maintain the uniform dispersion of different components in cosmetics, prevent precipitation, and enhance the stability of the product. It is especially suitable for products containing particulates or suspended particles, such as sunscreen. , liquid foundation and BB cream.

Cleansing and exfoliating: As a mild cleansing ingredient, Alginic Acid can help absorb and remove dirt and dead skin cells from the skin surface in cleansing and exfoliating products, while avoiding excessive removal of the skin’s natural oils and maintaining skin balance.

Anti-aging: Some studies have pointed out that alginic acid and its derivatives may have antioxidant properties, which can help resist free radical damage and slow down the skin aging process, so they also have application potential in anti-aging skin care products.

Naturalness and safety: As a natural ingredient derived from marine plants, Alginic Acid meets the current consumer demand for natural and green cosmetics, reduces the risk of skin irritation or allergy, and is suitable for sensitive skin.

Advantages of Alginic Acid

Natural source: Alginic Acid is a natural polysaccharide extracted from seaweed. This characteristic makes it popular in the fields of cosmetics, food and medicine, meeting the market demand for natural, sustainable and environmentally friendly raw materials.

Good biocompatibility: Due to its biological origin, Alginic Acid has good compatibility with human skin, is not likely to cause allergic reactions, is suitable for sensitive skin, and is widely used in personal care products.

Powerful moisturizing ability: Alginic Acid can absorb a large amount of water, form a moisturizing barrier, lock in skin moisture, effectively improve and maintain the skin’s hydration status, and is an ideal moisturizing ingredient.

Stable gelling properties: Under certain conditions, Alginic Acid can form stable gels with divalent metal ions (such as calcium and sodium). This property makes it a preferred ingredient for gels and molding agents in food and medicine. , such as when making capsules, tablets and wound dressings.

Good film-forming properties: Alginic Acid can form a thin and breathable protective film on the skin surface, which helps isolate external pollution and protect the skin without affecting the normal breathing of the skin.

Plasticity and adjustability: Through different processing methods, such as cross-linking and graft modification, the physical and chemical properties of Alginic Acid can be changed to adapt to the needs of different applications, such as controlling drug release speed, adjusting the viscosity and skin tone of cosmetics feel.

Environmentally friendly and degradable: As a bio-based material, Alginic Acid is biodegradable in nature and will not cause long-term burden to the environment, in line with the development trend of green chemistry.
