Oregano Liquid Extract (NSA): A Maker's Guide to Using It in Skin and Hair Care

Oregano Liquid Extract (NSA) is a cosmetic-grade herbal extract made from Origanum vulgare leaves, used at 1–2% in soaps, shampoos, serums, creams and other DIY personal-care products for its soothing, cleansing and refreshing feel. Azlok offers it in two versions — a water-soluble type extracted with vegetable glycerin and an oil-soluble type extracted with soy oil — so you can match it to whatever base your formula uses.

What is Oregano Liquid Extract?

This is a concentrated liquid drawn from oregano herb, sometimes known in India as ajwain, sathra or wild marjoram. The INCI name is Origanum Vulgare Leaf Extract (CAS 84012-30-6). It is prepared at a 4:1 herb-to-extract ratio, meaning roughly 4 kg of herb yields 1 kg of finished extract, so a little goes a long way. It is practically tasteless and odourless, which makes it easy to blend into products without changing their fragrance.

Different cultures have long turned to oregano preparations for skin comfort, scalp care and general hygiene. The plant naturally carries active compounds that formulators value for cleansing and refreshing effects, and it is often chosen for products aimed at balancing the scalp.

Where you can use it

• Soap making — cold process, melt-and-pour and liquid soaps.
• Shampoos and scalp tonics — where a fresh, balancing feel is the goal.
• Face washes and cleansers.
• Lotions, creams and body butters.
• Serums and DIY facial care.

Because it is available in water-soluble and oil-soluble forms, you can drop it into aqueous phases (toners, gels, shampoos) or oil phases (balms, serums, cream oil phase) without fighting the chemistry of your base.

How to use it in your formulations

The recommended usage rate is 1–2% of your total formula. Start low and adjust after testing.

1. Pick the right version — water-soluble (glycerin-based) for water systems, oil-soluble (soy-oil based) for oil systems.
2. Add it to the matching phase. Water-soluble goes into the water phase; oil-soluble blends into your oils.
3. For heat-sensitive formulas, add the extract during the cool-down phase, below 40°C, along with your other actives.
4. Weigh accurately with a small scale rather than eyeballing drops — 1–2% is easy to overshoot.
5. Always include a broad-spectrum preservative in any product that contains water.

Note that this extract carries BHT (butylated hydroxytoluene) as an antioxidant to protect the raw material; it is not a substitute for your finished product's preservative system.

Safety and honest notes

This is a cosmetic ingredient, not a medicine or a food. Do not ingest it and do not rely on it to treat any medical condition.

• Patch test your finished product on the inner forearm before regular use.
• Avoid direct contact with the eyes; rinse with plenty of water if it gets in.
• Keep it out of reach of children.
• Do not use it neat on skin at full strength — respect the 1–2% guideline.
• The product is stated to be free from gluten, artificial colour, heavy metals and fertilizers, but if you sell what you make, run your own stability and safety checks.
