Skin Perfection Leucidal Liquid natural preservative for lotions & serums 4oz — EcoCert, water-soluble

Leucidal Liquid from Skin Perfection is a natural, radish-root–derived preservative alternative that helps extend the shelf life of homemade lotions, serums, and creams without synthetic parabens or phenoxyethanol.

Formulated for clean-beauty makers, Skin Perfection Leucidal Liquid delivers mild antimicrobial support harvested from fermented radish root. It’s water-soluble, EcoCert-accepted, and designed to integrate into a range of DIY formulations—particularly water-based lotions, Vitamin C serums, and hyaluronic acid moisturizers. While not a one-step guarantee against all contamination, its gentle profile makes it a go-to ingredient for natural cosmetic creators seeking reduced synthetic preservatives.

How do I add Leucidal Liquid to my lotion or serum?

Add Leucidal Liquid during the final cooling phase of your formulation to preserve active ingredients and maintain efficacy. Use it below 70°C (158°F) and incorporate according to recommended percentages for stability and compatibility.

• Typical inclusion rate: around 4% of total formula.
• Add in the cooling phase once temperature is below 70°C (158°F).
• Mix thoroughly to ensure even distribution in water-based systems.
• Confirm final pH is within 3–8 for optimal performance.

Will Leucidal Liquid work with Vitamin C and hyaluronic acid?

Yes—Leucidal Liquid is formulated to be compatible with many popular actives used in DIY skincare, including Vitamin C derivatives and hyaluronic acid. It’s water-soluble and virtually odorless, so it won’t interfere with texture or scent in most serums and lotions.

• Compatible with water-based Vitamin C serums and HA formulations.
• Heat stable up to about 140°F (60°C) during processing.
• Minimal odor preserves fragrance choices.
• Works best when pH is kept between 3 and 8.

Is Leucidal Liquid safe and certified for natural skincare?

Leucidal Liquid is EcoCert-accepted and labeled GMO-free, making it suitable for many clean beauty projects. It’s free from common allergens and synthetic preservatives like parabens and phenoxyethanol, which appeals to formulators focused on milder ingredient lists.

• EcoCert-accepted and Whole Foods Market–friendly status.
• GMO-free, vegan-compliant, and water-soluble.
• Free from eggs, milk, peanuts, soy, tree nuts, wheat, and palm oil.
• Virtually odorless—preserves product scent profile.

Do I need to combine Leucidal Liquid with other preservatives?

For broader antimicrobial coverage, many formulators pair Leucidal Liquid with complementary actives like sodium benzoate or gluconates. Depending on the formula’s water activity and intended shelf life, combining ingredients can increase protection without reverting to harsher synthetic preservatives.

• Common pairing: sodium benzoate plus gluconic acid salts for enhanced coverage.
• Products with higher water content or exposure may need combined systems.
• Consider SF Max or Leucidal Complete for stronger natural protection options.
• Always practice good manufacturing hygiene and perform preservation efficacy tests.

Who is this product for? Skin Perfection Leucidal Liquid is intended for hobbyists, indie formulators, and small-batch skincare makers who prioritize natural, ECO-conscious ingredients. It suits creators making water-based lotions, serums, and moisturizers who want a milder preservative option that is easy to use, broadly compatible with popular actives like Vitamin C and hyaluronic acid, and accepted by natural-certifying organizations. If you need industrial-strength, single-ingredient antimicrobial protection for high-risk formulas, consider combining Leucidal with complementary agents and validating preservation through testing.
