Let’s dive deep.

🧴 What is Preservative Eco?

Preservative Eco is a broad-spectrum, nature-derived preservative commonly used in organic and natural skincare formulations.

It is approved by ECOCERT and COSMOS for use in natural cosmetics and is free from:

• ❌ Parabens

• ❌ Formaldehyde

• ❌ Phenoxyethanol

• ❌ Harsh synthetic chemicals

✅ Main ingredients:

• Benzyl Alcohol – natural antimicrobial agent

• Salicylic Acid – mild antifungal & antibacterial

• Sorbic Acid – fights mold and yeast

• Glycerin – skin-safe humectant that also boosts solubility

Together, these ingredients create a powerful system that prevents bacterial contamination in skincare products, especially those containing water or hydrosols.

✅ Why is Preservative Eco Necessary in Facial Creams and Lotions?

Water = life.
But in cosmetics, water also invites life forms you don’t want—like mold, bacteria, and yeast.

If you’re making or using a product that contains:

• Water

• Aloe vera

• Floral waters

• Hydrosols

• Herbal infusions

…then you’re creating an environment where microbes can easily grow without a preservative.

Preservative Eco helps to:

• Prevent contamination

• Extend shelf life

• Protect skin from harmful pathogens

• Keep your products clean and consumer-safe

🌟 Top Benefits of Using Preservative Eco in Skincare

1. 🦠 Broad-Spectrum Protection

Preservative Eco protects against:

• Gram-positive and gram-negative bacteria

• Yeast

• Mold

• Fungi

This makes it a complete preservation system that helps keep your skincare product safe for months—even without refrigeration.

2. 🌿 Eco-Friendly and Plant-Based

Approved by:

• ECOCERT

• COSMOS

• Soil Association

That means it’s ideal for:

• Organic skincare lines

• Vegan and cruelty-free products

• Clean beauty formulations

No need to compromise between efficacy and ethics.

3. 👩‍🔬 Ideal for Sensitive Skin

Because it’s free from common irritants, Preservative Eco is:

• Hypoallergenic

• Non-comedogenic

• Suitable for acne-prone, dry, and reactive skin

✅ Dermatologists and formulators often recommend it for delicate formulations, including baby care and sensitive face creams.

4. 💧 Perfect for Water-Based Formulas

Whether you’re making:

• Face creams

• Body lotions

• Toners

• Hair serums

• Gels and mists

Preservative Eco is designed to preserve water-containing products, which are high-risk for microbial growth.

5. 🔒 Extends Product Shelf Life

Without a preservative, water-based skincare can go bad in as little as 5–7 days.
With Preservative Eco, your product can last up to 12 months when stored properly.

That’s a game-changer for:

• Small businesses

• Indie brands

• DIYers who want to sell or gift their products

🧪 How to Use Preservative Eco in Your Skincare Formulas

✅ Usage Rate:

⚠️ Always check your formula’s total weight and calculate the preservative accordingly.

✅ pH Range Compatibility:

Preservative Eco is effective in formulations with a pH range of 3 to 8.
If your product falls outside this range, it may affect the preservative’s performance.

Use pH strips or a digital pH meter to test your final product.

✅ Best Time to Add:

• Add after the water and oil phases have cooled below 40°C

• Avoid adding to hot mixtures—high heat may destabilize it

• Mix thoroughly for even distribution

✅ Storage and Compatibility:

• Store in a cool, dry place

• Keep away from direct sunlight

• Compatible with most emulsifiers, oils, humectants, and active ingredients
