Olive Oil

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 olive oil. 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.

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: Olive oil is pressed from the fruit of the olive tree (Olea europaea). It is rich in oleic acid and, in extra-virgin grades, squalene, vitamin E, and polyphenols. In ORY^® products, it is a conditioning emollient in blends, an infusion base, and the foundation of our mildest handmade soaps.

Verification: Supported. The Cosmetic Ingredient Review (CIR) Expert Panel found plant-derived fatty acid oils, including olive fruit oil, safe as used in cosmetics. CIR has begun an updated review of edible plant oils.

  - What it shows: Review of olive oil (mainly nutritional).

2. Composition and Production

Claim: Olive oil is about 65–80% oleic acid, with linoleic, palmitic, and stearic acids. Extra-virgin grades also contain squalene and polyphenols such as hydroxytyrosol.

Verification: Supported. Its fatty-acid profile is well documented.

  - What it shows: Describes composition.

3. Skin Type Suitability

Claim: Olive oil suits dry and mature skin when blended with other oils. It should not be used on its own as a leave-on oil for damaged, eczema-prone, or infant skin.

Verification: Supported. In a controlled study of 19 adults, applying pure olive oil to the forearm for about four weeks weakened the skin barrier and caused mild redness, while sunflower oil did not. ORY^® therefore blends olive oil with other oils in leave-on products.

  - What it shows: Controlled study of olive oil and the skin barrier.

4. Hair and Scalp Suitability

Claim: In haircare, olive oil helps thick, dry, or coily hair feel soft and conditioned.

Verification: Limited evidence. Oils are commonly used to soften hair and reduce the look of frizz; we found no controlled clinical studies of this oil on hair. ORY^® haircare products are not intended to treat dandruff, scalp conditions, or hair loss.

  - What it shows: General review.

5. Benefits

Claim: Olive oil helps skin and hair feel soft, and makes a very mild, conditioning soap.

Verification: Supported, with caveats. Olive oil’s antioxidant compounds are well described, mostly in nutrition research. Its main value in ORY^® products is as a blended emollient, infusion base, and soap oil.

  - What it shows: Review of plant oils.

6. Use Across ORY^® Product Lines

Claim: Olive Oil is used in all four ORY^® product lines.

Verification: Supported. In leave-on skincare, olive oil is used only in blends.

Product line	Typical level	How ORY^® uses it
Skincare	5–30% in blends	Blended body oils, cleansing oils, balms, creams, and infusion base.
Haircare	5–50%	Hair masks and pre-shampoo oils for thick or dry hair.
Handmade Soap	30–100% of oils	Primary conditioning oil; Castile (100%) or blended bars.
Cosmetics	5–20%	Lip balms, cleansing balms, and cream products.

7. Pros

Claim: A mild, conditioning oil and the foundation of Castile soap, with a CIR safety conclusion.

Verification: Supported. Well documented composition and long cosmetic use.

Citations:

- Burnett, C. L., et al. (2017). Safety assessment of plant-derived fatty acid oils. International Journal of Toxicology, 36(3 Suppl), 51S–129S. https://doi.org/10.1177/1091581817740569
  - What it shows: Safety conclusion.

8. Cons

Claim: Pure olive oil can weaken the skin barrier, feels heavy, and makes slow-curing soap.

Verification: Supported. We list these limits so you have the full picture:

- Barrier effect. Pure olive oil weakened the adult skin barrier in a controlled study.
- Not for infant skin alone.
- Heavy. Slow to absorb.
- Soap. Low lather and a long cure at high levels.

  - What it shows: Barrier study.

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.
- Do not use pure olive oil on babies, broken skin, or eczema-prone skin.
- Store away from heat and light, and discard if it smells rancid.
- Stop use if redness, burning, itching, or rash occurs, and talk to a healthcare provider.
- For external use only. Avoid the eyes.
- If you are pregnant, nursing, have a medical condition, or are buying for a child, ask a healthcare provider before use.
