Walnut oil is a cold-pressed carrier oil made from the nuts of Juglans regia, prized both as a nutty finishing oil in the kitchen and as a light, fast-absorbing base oil for skin and hair care. Azlok's walnut oil is thin in consistency, pale yellow in colour, and rich in linoleic, oleic and alpha-linolenic fatty acids, which is why it works across food and DIY beauty.
What walnut oil is used for
This is a genuinely versatile oil. Because it has a thin texture and absorbs quickly, it suits people who dislike heavy, greasy oils.
- As a finishing oil in food: drizzle over salads, roasted vegetables, pasta or soups for a warm, nutty flavour. It is best used unheated or added at the end of cooking.
- In skincare: used as a diluted facial and body oil, it is often chosen for its light feel and its fatty-acid content, which supports the skin's moisture barrier.
- In hair care: a small amount smoothed through the lengths can add shine and tame frizz without weighing hair down.
- In DIY blends: it pairs well with sweet almond oil and grape seed oil, making it a useful base for massage oils, serums and balms.
How to use walnut oil
The right method depends on whether you are cooking or applying it to your body.
In the kitchen
Treat it like a specialty finishing oil rather than a frying oil. Its flavour and nutritional profile are best preserved when it is not exposed to high heat. Use it in dressings, dips, or as a last-minute drizzle. A little goes a long way.
On skin and hair
- Always dilute before topical use. As a carrier oil it can be used on its own in small amounts, or mixed with other carrier oils and a few drops of an essential oil for a custom blend.
- For a facial oil, a few drops massaged into slightly damp skin at night is usually enough.
- For hair, warm a small quantity between your palms and work it through the mid-lengths and ends.
Safety and patch testing
Walnut oil is derived from a tree nut, so a little care goes a long way — especially if you have a nut allergy.
- Do a patch test on the inner forearm and wait 24 hours before wider use.
- Dilute it before applying it to the skin, and avoid the eye area.
- Avoid direct sun exposure right after application, as with most oils.
- Pregnant or breastfeeding women should consult a doctor before regular use.
- If you have a known walnut or tree-nut allergy, avoid both eating and applying it.
- Keep out of the reach of children.
We describe traditional and cosmetic uses here — walnut oil is not a medicine and should not replace professional medical advice or treatment.
Buying and storing walnut oil
Look for cold-pressed oil, which is extracted without heat and retains more of its natural character. Azlok's walnut oil is cold-pressed, of Indian origin, and available in sizes from a 100 GM bottle up to bulk 25 KG packs, so home users and small businesses can both buy what they need. Pricing starts at ₹329.
- Store in a cool, dark place, away from direct sunlight and heat.
- Keep the cap tightly closed to slow oxidation; the oil has a shelf life of around two years unopened.
- Once opened, use it within a reasonable time and watch for any change in smell — a sharp, rancid odour means it is past its best.
- Refrigeration can extend freshness, particularly for culinary use.
FAQ
Can I cook with walnut oil?
Yes, but use it as a finishing oil rather than for deep frying. Its nutty flavour and delicate fatty acids are best enjoyed when it is added to food unheated or right at the end of cooking.
Is walnut oil good for the face?
Many people use it as a light facial oil because it absorbs quickly and is rich in linoleic acid. Dilute it, do a patch test first, and start with just a few drops at night.
Which oils blend well with walnut oil?
It blends nicely with sweet almond oil and grape seed oil, making a good base for massage oils and serums. You can add a few drops of your preferred essential oil to the mix.
Is walnut oil safe for people with nut allergies?
No. Since it comes from a tree nut, anyone with a walnut or tree-nut allergy should avoid both eating and applying it. When in doubt, consult a doctor.
How long does walnut oil last?
Unopened and stored in a cool, dark place, it keeps for about two years. Once opened, use it steadily and discard it if the smell turns sharp or rancid.
