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 Rosemary + Green Tea Infused Squalane / Caprylic-Capric Triglyceride. 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: Some studies on this page tested rosemary and green tea for medical conditions, including hair loss, and most used extracts, creams, or oral forms rather than an oil infusion. We share them for transparency. ORY® infused oils are cosmetics and are not intended to treat any condition, grow hair, or prevent hair loss.
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: Rosemary + Green Tea Infused Squalane / Caprylic-Capric Triglyceride is an ORY® Build-Your-Own infused oil: dried rosemary and green tea steeped in the customer’s choice of Squalane or Caprylic/Capric Triglyceride, then strained and protected with vitamin E and rosemary extract. It helps skin and hair feel soft, nourished, and comfortable, and helps the scalp feel refreshed. |
Verification: Supported. The Cosmetic Ingredient Review (CIR) Expert Panel has found each component safe in cosmetics: rosemary-derived ingredients are safe when formulated to be non-sensitizing; green tea leaf ingredients are safe when formulated to be non-sensitizing; squalane is safe as used; caprylic/capric triglyceride is safe as used. CIR has not reviewed this specific blend.

2. Composition and Production
Claim: Dried rosemary leaves contribute oil-soluble antioxidants (carnosic acid and carnosol) and aromatic terpenes. This is a leaf infusion, not rosemary essential oil. Green tea leaves contribute some catechins (mainly water-soluble, so only partly captured by oil), chlorophyll, and aroma compounds. The carrier makes up most of the product. Squalane is weightless and non-greasy and suits all skin types. Caprylic/Capric Triglyceride is light, odorless, and stable and suits all skin types. |
Verification: Supported. ORY® steeps dried (never fresh) botanicals in the carrier, strains them out, and adds 0.5–1% vitamin E and 0.1% rosemary extract. An oil infusion captures mainly oil-soluble compounds, so its strength differs from the extracts used in research. ORY® infused oils are made by steeping dried plant material in a carrier oil. The carrier oil makes up most of the finished product, so its own properties matter as much as the botanical’s — including allergy: nut-derived carrier oils such as sweet almond oil may not suit people with tree-nut allergies.

3. Skin Type Suitability
Claim: This infused oil suits all skin types, including oily and combination skin, because both carriers are light and non-greasy. |
Verification: Supported, with caveats. We found no clinical studies of this blend. Suitability is based on the carrier and the safety data for each ingredient.

4. Hair and Scalp Suitability
Claim: In haircare, this infused oil helps hair feel soft and look glossy and helps the scalp feel refreshed. |
Verification: Limited evidence. A trial in people with androgenetic alopecia used rosemary essential oil, not a leaf infusion, and a mouse study used rosemary leaf extract. A lab study found EGCG stimulated cultured hair follicles. Hair-growth and hair-loss claims are drug claims, and ORY® does not make them. ORY® haircare products are not intended to treat dandruff or scalp conditions.

5. Benefits
Claim: This infused oil helps skin and hair feel soft, smooth, and nourished and provides antioxidant support. |
Verification: Supported, with caveats. Most of the moisturizing benefit comes from the carrier. Rosemary’s antioxidant activity is well documented in lab studies. A study of citrus and rosemary extract taken by mouth does not apply to a topical oil. Human studies of green tea for sun protection and acne used water-soluble polyphenols or EGCG, not an oil infusion, and those are drug claims. ORY® does not make wound, eczema, acne, sun-protection, or hair-growth claims for this oil.

6. Use Across ORY® Product Lines
Claim: Rosemary + Green Tea Infused Squalane / Caprylic-Capric Triglyceride is used in all four ORY® product lines; its soap role depends on the carrier. |
Verification: Supported. Soap use by carrier: Squalane — does not saponify; superfat only (1–3%); Caprylic/Capric Triglyceride — small superfat only (2–5%). Being oil-only, the infusion needs no preservative if kept free of water.
| Product line | Typical level | How ORY® uses it |
| Skincare | 5–100% | Lightweight face oils, antioxidant serums, and cleansing oils (CCT). |
| Haircare | 10–100% | Leave-in scalp serums and silicone-free shine serums (squalane). |
| Handmade Soap | 1–5% superfat | Superfat at trace only. |
| Cosmetics | 5–30% | Brow serums, lip oils, and foundation slip. |

8. Cons
Claim: Infusion strength varies, the botanical research used other forms, and some ingredients carry allergy cautions. |
Verification: Supported. We list these limits so you have the full picture:
- Variable strength. Depends on botanical quality, ratio, and steeping time.
- Different forms in research. Studies used extracts, creams, essential oils, or oral products, not this infusion.
- Partial capture. Oil captures only part of green tea’s water-soluble catechins.
- Camphor. Rosemary leaf contains small amounts of camphor and 1,8-cineole.
- No blend-specific trials. Evidence is for individual ingredients.

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.
- Rosemary contains camphor. If you have epilepsy or a seizure disorder, ask a healthcare provider before use.
- If you have a nut or seed allergy, check the carrier before use.
- Store away from heat and light, keep water out of the bottle, 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.
