Hydroxybenzoates (Parabens): Complete Information from AIHerba | Supplier & Manufacturer
1. Hidroksibenzoatlar nədir?
Hydroxybenzoates, generally referred to as parabens, are a gaggle of artificial or naturally derived esters of para-hydroxybenzoic acid. They perform primarily as extremely efficient geniş spektrli konservantlar in cosmetics, prescribed drugs, meals, and drinks. Their efficacy lies in inhibiting microbial progress (micro organism, fungi, yeasts) by disrupting cell membrane integrity and enzyme exercise. Widespread sorts embody Methylparaben (Methyl 4-hydroxybenzoate), Ethylparaben, Propylparaben, and Butylparaben, differing by their alkyl chain size (methyl, ethyl, propyl, butyl).
2. Məhsul Təchizatı, Kimyəvi Xüsusiyyətlər və İdentifikatorlar
-
Təchizat: Whereas synthetically produced for industrial scale and consistency, the core para-hydroxybenzoic acid construction may be naturally present in some fruits (e.g., blueberries, cloudberries). AIHerba provides each artificial and bitki mənşəli hidroksibenzoatlar utilizing superior extraction and esterification methods.
-
Kimyəvi xassələri:
-
Görünüş: Sometimes white crystalline powders.
-
Həlletmə qabiliyyəti: Low solubility in water; increased solubility in alcohols, ethers, and acetone.
-
Sabitlik: Steady below regular processing circumstances (warmth, pH vary 3-8). Efficient at low concentrations (usually 0.01%-0.3%).
-
Mode of Motion: Penetrates microbial cell partitions/membranes, interfering with membrane transport and inhibiting key metabolic enzymes.
-
-

3. Efficacy, Well being Affect & Security
-
“Finest” Kind & Focus: There is not any single “greatest” paraben; efficacy is determined by software pH, required spectrum, and formulation compatibility. Usually, blends (e.g., Methyl and Propylparaben) are used synergistically for broader safety. AIHerba provides high-purity grades (>99.5%) exceeding business requirements.
-
Well being Benefits (Operate): Their major profit is məhsulun qorunması, stopping spoilage and potential infections from contaminated merchandise. That is essential for client security. Claims of direct içəridə well being advantages for parabens are inaccurate and unsupported.
-
Day by day Consumption & Security: Regulatory our bodies globally (FDA, EFSA, SCCS) set up strict Acceptable Day by day Consumption (ADI) ranges based mostly on intensive toxicology. For instance, the ADI for Methylparaben is 0-10 mg/kg physique weight/day. Precise publicity from correctly preserved merchandise is often far beneath ADI limits.
-
Ehtiyat tədbirləri və Aspekt Nəticələr:
-
Allergik reaksiyalar: Uncommon, however attainable pores and skin sensitization (contact dermatitis) can happen in prone people, particularly with increased concentrations or compromised pores and skin boundaries.
-
Endocrine Disruption Issues: Debate exists relating to potential weak estrogenic exercise in vitro and at very excessive doses in vivo. Nevertheless, present scientific consensus, backed by regulatory critiques (e.g., SCCS Opinion 2021), concludes that parabens (particularly methyl- and ethyl-) are protected at licensed concentrations in cosmetics (usually max 0.4% for single ester, 0.8% whole for mixtures). AIHerba adheres strictly to international regulatory limits.
-
İstifadə edin: Observe beneficial utilization ranges for particular functions. Patch testing new beauty formulations is prudent.
