At ORY®, we believe you should know what’s in your products and why. This page lists the published research behind what we say about ethylhexylglycerin. Each section starts with our claim, then tells you how well the research supports it, then lists the sources so you can read them yourself.
Please note: Preservatives protect water-containing products from bacteria, yeast, and mold. They do not treat the skin or prevent infection on the skin. Every ORY® water-based formula should pass a preservative efficacy (challenge) test, such as USP <51> or ISO 11930, before sale.
How to read this page Supported — backed by peer-reviewed research or official safety reviews. Supported, with caveats — the research points this way, but mostly from laboratory or animal studies, or at different strengths than ORY® uses. Limited evidence — little or no published research yet. We say so openly. |
1. General Description and Role
Claim: Ethylhexylglycerin is a skin-conditioning ingredient that also boosts preservatives such as phenoxyethanol, so less total preservative is needed. In ORY® products, it helps protect water-based formulas and gives a soft skin feel. |
Verification: Supported. The Cosmetic Ingredient Review (CIR) Expert Panel concluded that ethylhexylglycerin is safe in cosmetics in the present practices of use and concentration.

2. Composition and Production
Claim: Ethylhexylglycerin is a glyceryl ether made by reacting glycerin with 2-ethylhexanol. It is a clear, nearly odorless liquid used at about 0.3–1.0%, usually with phenoxyethanol. |
Verification: Supported. Its chemistry is well documented. The 2-ethylhexanol part may come from plant or petrochemical sources.

3. Skin Type Suitability
Claim: At its use level, ethylhexylglycerin is suitable for all skin types. |
Verification: Supported, with caveats. Contact allergy is uncommon but has been reported, including from products labeled hypoallergenic. People with dermatitis-prone skin should patch test.

4. Hair and Scalp Suitability
Claim: In haircare, ethylhexylglycerin (with a primary preservative) protects water-based shampoos, conditioners, leave-ins, and scalp products from microbial growth. It has no direct effect on hair. |
Verification: Supported. This is a formulation role; ORY® haircare products are not intended to treat dandruff or scalp conditions.

5. Benefits
Claim: Ethylhexylglycerin helps preservatives work at lower levels, gives a soft feel, and helps control odor in deodorants. |
Verification: Supported. Deodorant use (controlling odor) is a cosmetic use; ORY® does not claim it reduces sweating, which would be a drug claim. Preservation protects the product, not the skin.

8. Cons
Claim: Ethylhexylglycerin can occasionally cause allergy and is not a preservative on its own. |
Verification: Supported. We list these limits so you have the full picture:
- Allergy. Uncommon but documented.
- Not stand-alone. Must be paired with a primary preservative.
- Stinging on broken skin. Can sting on damaged skin.
- Challenge testing needed. Efficacy must be confirmed in each formula.

9. Safety Notes
Claim: Patch test before use; for external use only. |
Verification: Supported. Follow these precautions:
- Patch test any new product on a small area for 24–48 hours before full use.
- If you know you are allergic to ethylhexylglycerin, avoid products that contain it.
- Water-based products are only as safe as their preservation. Keep lids closed, do not add water to the product, and discard it if it changes color, smell, or texture.
- Stop use if redness, burning, itching, or rash occurs, and talk to a healthcare provider.
- For external use only. Avoid the eyes unless the product is made for the eye area.
- If you are pregnant, nursing, have a medical condition, or are buying for a child, ask a healthcare provider before use.

10. Product-line notes
- ORY® Skincare: For external use only. Not for deep or puncture wounds, animal bites, or serious burns.
- ORY® Haircare: Designed for the look and feel of hair and scalp comfort. Not intended to treat dandruff or scalp conditions, or to promote hair growth or prevent hair loss.
- ORY® Handmade Soap line: Cold-process bars contain very little free water and do not need this preservative. It is used only in liquid soaps, cream soaps, and water-containing syndet products; syndet and cream products are cosmetics under FDA rules, not soap, and list all of their ingredients.
- ORY® Cosmetics: Do not share applicators, and replace any product that changes color, smell, or texture.
