Alginates (sodium alginate, calcium alginate)
Category: Thickener, stabilizer
Brief description: Alginates are natural polysaccharides extracted from brown seaweed (Phaeophyceae), used to thicken and stabilize cosmetic formulations. Sodium alginate and calcium alginate are the most commonly used forms.
Benefits: Provides viscosity, enhances texture, and stabilizes emulsions in cosmetic products.
Skin type suitability/concerns: Suitable for all skin types.
Target audience: All age groups and demographics.
Chemical composition: Alginates are high-molecular-weight polysaccharides consisting of mannuronic acid and guluronic acid units.
Physical aspect: Off-white to yellowish powder or granules.
Compatibility: Compatible with a wide range of cosmetic ingredients, including water, oils, and other thickeners and stabilizers.
Concentration: Typically used at 0.5-5% in cosmetic formulations.
Side effects/adverse reactions: Generally safe for use in cosmetics, with a low risk of irritation or allergic reactions.
Regulatory status: Approved for use in cosmetics worldwide, with no specific restrictions.
Sustainability/ethical considerations: Alginates are biodegradable, derived from renewable resources, and considered an eco-friendly ingredient.
