Skin Perfection Leucidal Liquid natural preservative for DIY lotions — 4oz, EcoCert vegan, water-soluble, heat-stable

Leucidal Liquid by Skin Perfection is a radish-root fermentation preservative that helps keep homemade lotions, creams and serums fresher without synthetic parabens. Made for formulators who prioritize natural ingredients, this water-soluble Leucidal Liquid provides mild antimicrobial support and pairs well with a variety of cosmetic bases. EcoCert-approved and vegan-compliant, it’s used as an alternative to conventional preservatives in DIY skincare like hyaluronic-body lotions, vitamin C serums, and everyday moisturizers. The product is odor-light, heat-stable to about 140°F (60°C), and intended to be added during the cooling phase of formulation for best results.

How do I use Leucidal Liquid in my DIY lotion recipes?

Add Leucidal Liquid to your formulations during the cooling phase (below 70°C/158°F) to maintain its activity. Typical usage is around 2–4% of the total formula, depending on the product type and your desired protection level. Always monitor final pH and follow good manufacturing hygiene for best outcomes.

• Use at about 4% for general lotions and creams.
• Add during the cool-down stage, below 70°C to preserve potency.
• Check product pH; Leucidal performs across pH 3–8.
• Combine with other approved actives for broader protection when needed.

Will Leucidal Liquid work with vitamin C serums and hyaluronic acid?

Yes — Leucidal Liquid is water-soluble and formulated to be compatible with humectants like hyaluronic acid and antioxidant serums. Because vitamin C formulations can be sensitive, validate compatibility and stability through small-batch testing before scaling up. Pairing with complementary preservatives or stabilizers is recommended when creating high-risk formulations.

• Compatible with water-based serums and hyaluronic acid systems.
• Recommended to test small batches for color, odor, and stability.
• Consider pairing with sodium benzoate or gluconates for extra protection.
• Works best when final pH remains within 3–8 range.

Is Leucidal Liquid safe and what certifications does it have?

Leucidal Liquid is EcoCert-approved, GMO-free, and accepted by Whole Foods, which supports its positioning in clean-beauty formulations. It is derived from fermented radish root and is free from many common allergens and problematic ingredients, making it a popular choice for sensitive-skin-friendly product lines. As with all preservatives, observe formulation hygiene and perform microbial challenge tests for commercial applications.

• EcoCert-approved and Whole Foods accepted.
• GMO-free, vegan-compliant, and virtually odorless.
• Free from common allergens like eggs, nuts, soy, dairy, and palm oil.
• Not a universal single-solution; consider challenge testing for saleable products.

How should I store and measure Leucidal Liquid for best longevity?

Keep the product tightly sealed and stored in a cool, dry spot away from direct sunlight to preserve activity and shelf life. Use precise measuring tools when formulating to maintain consistent preservative levels across batches and always follow sanitation protocols during production.

• Store sealed in a cool, dark place to maintain efficacy.
• Measure by weight or accurate graduated pipettes for consistency.
• Keep containers clean and use within expected shelf period after opening.
• Heat stability up to roughly 140°F — avoid prolonged high-heat exposure.

Who is this for? Skin Perfection Leucidal Liquid is aimed at DIY formulators, small-batch skincare makers, and clean-beauty brands seeking a plant-derived preservative alternative. If you create water-based lotions, serums, or moisturizers and want an EcoCert-approved, GMO-free option that integrates well with humectants and light serums, this Leucidal Liquid is a practical tool. Note: for commercial-scale or higher-risk formulas, pair with complementary preservatives and perform required microbial challenge testing before market release.
