Chelator natural
Description
Natural Chelator – Sequestering Agent, Antioxidant, Acid pH Regulator
Natural Chelator based on phytic acid derived from plant seeds and bran, supplied as a concentrated aqueous solution. Used as a high-performance, eco-friendly, and fully biodegradable chelating (sequestering) agent, representing a natural alternative to synthetic chelators like EDTA. It has the ability to bind and neutralize free metal ions in formulas, preventing oxidative degradation, color shifts, and rancidity of lipid components, while simultaneously acting as an efficient acidifying agent for cosmetic compositions.
Ingredients (INCI): Phytic Acid, Aqua.
Technical Characteristics
- Appearance: Fluid liquid, slightly yellowish, characteristic odor.
- Solubility: Completely water-soluble.
- Raw Material pH (Pure): 1.0 - 2.0 (strongly acidic, specific value).
- Cosmetic Function: Chelating agent, sequestering agent, antioxidant, pH regulator (acidifier), formula stabilizer.
- Indicative Dosage: 0.05% - 0.2%.
Main Properties
- Metal Ion Sequestration: Effectively binds metal ions, blocking reactions that lead to the oxidative degradation of vegetable oils and essential oils in the formulation.
- Acidifying Effect: Due to its acidic nature, it acts as a pH adjuster, allowing alkaline or neutral values to be lowered into the physiological acidic range, partially or fully replacing citric/lactic acid.
- Preserving Booster: By binding calcium and magnesium ions at interfaces, it weakens the outer membranes of Gram-negative bacteria, facilitating much faster penetration of preservative systems.
- Prevention of Chromatic Changes: Prevents interaction between metal impurities and pigments or botanical extracts, reducing the risk of discoloration or yellowing of creams over time.
Applications
- O/W and W/O emulsions: moisturizing creams, body lotions, and serums.
- Hygiene products: shampoos, shower gels, facial cleansers, and liquid soaps.
- Purely aqueous formulations: toners, micellar waters, gels, and serums.
- Formulas containing polyphenolic extracts or sensitive antioxidants - green tea, ginkgo biloba, vitamin C, ferulic acid.
Formulation Guide
The strongly acidic nature of phytic acid mandates clear handling and pH monitoring rules during the manufacturing process:
- Procedure: Adding the natural chelator into the initial water phase is recommended due to its immediate solubility and high heat stability. Alternatively, it can be introduced at the end of preparation during the cooling phase, mixing until completely dispersed.
- pH Management: Adding this product will significantly drop the pH of the water phase or emulsion. It is mandatory to measure the pH at the end of formulating. If the pH drops below the optimal threshold or below the activity limit of the preservative used, it must be adjusted upwards (alkalized) drop by drop using a diluted Sodium Hydroxide or Arginine solution.
- Recommended Usage Dosage: 0.05% - 0.2%. A standard concentration of 0.1% is optimal to ensure the stability of most emulsions and aqueous solutions.
- Thermal Stability: Excellent, withstands standard emulsification temperatures.
Safety in Use and Storage
Safety Profile: Biodegradable plant-derived compound, safe for cosmetic use at recommended concentrations. Well tolerated dermatologically after proper dilution and pH adjustment in the finished product.
Precautions: For external cosmetic use only. In its pure, concentrated state, the liquid is strongly acidic; handle with care, avoiding direct contact with eyes, skin, or mucous membranes. In case of contact, rinse immediately with plenty of water. Keep out of reach of children.
Storage: Store in the original tightly closed container, in a dry, cool place.
