Frequently Asked Questions

What is gluconolactone and sodium benzoate?
Gluconolactone and sodium benzoate is a natural, broad-spectrum preservative blend used to protect water-containing skincare products. Gluconolactone is a polyhydroxy acid that works as a humectant, mild chelating agent, and preservative booster, while sodium benzoate is the salt of benzoic acid that provides antimicrobial activity, especially in acidic environments (benzoic acid has a pKa around 4.2). The combination is accepted by Ecocert and supplied as a stable powder that is GRAS and non-GMO, which makes it attractive for natural and organic formulations. This blend helps prevent bacterial, yeast, and mold contamination while adding gentle moisturizing benefits. Ingredient-savvy DIY formulators and small-batch makers who want Ecocert-compatible, low-irritant preservation benefit most. Note that efficacy depends on formulation factors such as pH, water activity, and dose, so professional challenge testing or following supplier usage guidelines is recommended.
What is the safest preservative for skincare?
There is no single safest preservative for all skincare; safety is determined by toxicology data, regulatory acceptance, concentration, and how it performs in a specific formula. Preservative safety is evaluated by measures such as allergenicity, systemic exposure limits, and regulatory lists. Natural options like gluconolactone plus sodium benzoate have favorable profiles because they are Ecocert-accepted, GRAS, and tend to be low-irritant while offering broad-spectrum activity, but safety still depends on correct concentration and product pH. Formulators making products for sensitive or mature skin benefit from milder, well-documented systems with moisturizing co-benefits. For true safety assurance, conduct preservative challenge testing, follow supplier guidance, and include patch testing for finished products, because even gentle preservatives can cause reactions in some individuals.
Is GSB Natural Preservative Powder suitable for DIY water-based serums and creams?
Yes. GSB Natural Preservative Powder is suitable for many DIY water-based serums and lotions when used with proper formulation controls. The powder pairs gluconolactone, which adds humectant and chelating support, with sodium benzoate, which provides antimicrobial action in the presence of water; the blend is Ecocert-accepted and designed for broad-spectrum protection in acidic to mildly acidic systems. Its powdered form is convenient for accurate measurement into the water phase of serums, hyaluronic acid gels, and lightweight creams. This product particularly benefits DIY formulators and ingredient-savvy users creating peptide serums or natural moisturizers who want preservative protection without harsh synthetics. Limitations include pH sensitivity and water activity: very high-pH or unusually high-risk formulas may require alternative or additional preservatives and professional challenge testing for reliable long-term preservation.
Can I use Skin Perfection’s GSB Natural Preservative Powder in organic and eco-certified skincare formulations?
Yes, Skin Perfection’s Gluconolactone & Sodium Benzoate (GSB) Natural Preservative Powder is suitable for use in organic and eco-certified skincare formulations. This preservative is approved by Ecocert, a leading certifying organization for natural and organic cosmetics, and it features naturally derived ingredients with a non-GMO and GRAS (Generally Recognized as Safe) status. Thanks to its broad-spectrum antimicrobial effectiveness and gentle, skin-friendly profile, GSB is popular among formulators aiming to meet clean beauty standards without compromising product safety or shelf life. It’s especially beneficial for ingredient-conscious DIY enthusiasts and professionals looking to craft preservative systems that align with green beauty values. While GSB covers a wide range of bacteria and yeasts, those needing mold-specific protection may still want to assess their recipe’s unique preservation needs.
Can I use Skin Perfection’s Gluconolactone & Sodium Benzoate (GSB) Natural Preservative Powder in products with active peptides?
Yes, Skin Perfection’s GSB Natural Preservative Powder is compatible with skincare formulas containing active peptides, including Matrixyl 3000, Argireline, and Syn-Coll. Its gentle, non-denaturing action preserves the bioactivity of sensitive peptide complexes, making it ideal for those formulating high-performance anti-aging products at home. GSB works effectively at typical peptide serum pH levels (3–6) and does not require high temperatures, further protecting delicate actives. Ingredient-savvy women who want clinical-strength, DIY peptide serums without the risk of peptide breakdown or harsh preservatives will benefit most from this preservative system. However, it’s important to use the recommended concentration (typically 0.75–2%) and routinely check final product pH for optimal preservation.
