Euxyl K 903 Preservative: The Complete Glimmer Goddess® Clean Beauty Guide
Clean beauty isn’t just about what you include in a formula — it’s about what you protect your customers from. Even the most luxurious organic skincare requires a safe, gentle preservative system to prevent the growth of harmful bacteria, yeasts, and mold. At Glimmer Goddess®, we use Euxyl K 903, one of the cleanest, most sensitive-skin-friendly preservative systems validated in modern cosmetic science.
This guide explains what Euxyl K 903 is, why we use it, how it supports product safety, and why it’s essential for every water-based clean beauty formula — handcrafted in Texas.
What Is Euxyl K 903?
Euxyl K 903 is a gentle, broad-spectrum preservative system designed specifically for natural and organic skincare. It protects products from microbial contamination while maintaining a low irritation profile — making it ideal for small-batch clean beauty brands and customers with sensitive skin.
It contains three components:
- Benzyl Alcohol — a naturally occurring aromatic alcohol used for antimicrobial protection
- Ethylhexylglycerin — a skin-conditioning agent that boosts preservative efficacy
- Tocopherol (Vitamin E) — antioxidant support
Together, these ingredients deliver a clean, effective, and stable preservation system approved for use in natural and organic cosmetic formulations.
Is Euxyl K 903 Natural?
Euxyl K 903 is considered a clean, nature-aligned preservative system. While not “raw plant material,” each component is permitted under clean beauty guidelines because:
- They are non-paraben and non-formaldehyde-releasing
- They are allowed in certified natural formulations globally
- They are low-irritation and non-sensitizing
- They are biodegradable and eco-approved
This makes Euxyl K 903 an excellent match for Glimmer Goddess® formulations where ingredient purity and skin gentleness matter.
Why Preservatives Are Essential in Clean Beauty
Any formula containing water, aloe juice, hydrosols, or botanicals requires a preservative — even in organic skincare. Without one, the product can grow bacteria and mold within days or weeks, causing irritation or infection.
Euxyl K 903 allows us to formulate:
- Safely
- Without parabens
- Without synthetic fragrance
- Without formaldehyde releasers
It delivers powerful antimicrobial protection with a clean beauty profile aligned with global natural cosmetic standards.
Ingredient Breakdown: What Is Benzyl Alcohol + Ethylhexylglycerin + Tocopherol?
Benzyl Alcohol
A naturally occurring aromatic alcohol found in apricots, cranberries, jasmine, and essential oils. Used for antimicrobial protection with a mild profile suitable for sensitive skin when used at low concentrations.
Ethylhexylglycerin
A skin-conditioning humectant derived from glycerin. It improves the feel of the formula while boosting the antimicrobial effectiveness of benzyl alcohol — reducing the need for harsher preservatives.
Tocopherol (Vitamin E)
An antioxidant that helps protect oils from oxidation and supports overall formula stability.
Together, these provide a balanced, gentle preservation system ideal for Glimmer Goddess®' clean formulations.
Is Euxyl K 903 Safe for Sensitive Skin?
Yes. When used at appropriate levels, Euxyl K 903 is considered one of the lowest-irritation preservative systems available for clean beauty.
It is ideal for:
- Sensitive skin
- Dry skin
- People avoiding parabens
- People avoiding synthetic fragrance
- Customers who want clean and gentle formulas
This is why we selected it as our primary preservative system across Glimmer Goddess® face and body moisturizers, serums, and treatments.
What Is the Shelf Life of Euxyl K 903?
Euxyl K 903 helps maintain product integrity for 12–24 months depending on:
- Formula type
- Storage conditions
- Packaging
- Exposure to air or water
Most Glimmer Goddess® products feature a shelf life of 12 months after opening, supported by the safety and stability provided by Euxyl K 903.
The Safest Preservative for Clean Beauty?

Euxyl K 903 is one of the safest, most reliable options for water-based organic skincare.
It offers:
- High safety margin
- Clean formulation profile
- Low irritation potential
- Global approval in natural cosmetic standards
