A tallow balm you blend at home takes essential oil at one percent of its weight or less, and a baby's balm takes none. On a face or lips, it's half a percent. Lavender and frankincense suit a face or a body, while peppermint and the citrus oils stay on the body. Our essential oil dose calculator sets both numbers as ceilings, not targets.
If you'd rather leave the vials on the shelf, I'd hand you Bare Silk Unscented ($34 as of October 6, 2026). It's five ingredients long, and not one of them is an essential oil.
Which essential oils are best for tallow balm?
There's no single best one: it's a scent you like, at a dose your skin tolerates.
| Oil | Why add it | Calculator allows | Watch for |
|---|---|---|---|
| Lavender | Soft floral scent | Face or body | An EU-listed allergen |
| Frankincense | Warm resin scent | Face or body | Oxidizes once opened |
| Chamomile | Mild, sweet herbal scent | Face or body | Ragweed or daisy allergy |
| Helichrysum | Honeyed herbal scent | Not listed | It's in our Recovery Balm |
| Tea tree | Sharp, clean scent | Face or body | Old oil sensitizes skin |
| Peppermint | Cooling feel on feet | Body only | Caution with young children |
| Citrus | Bright top note | Body only | Some grades are phototoxic |
Plant-sourced doesn't mean allergen-free. Linalool, limonene, geraniol and citronellol were on Europe's first list of fragrance allergens, the EU's consumer safety committee notes, and European leave-on labels must name them above 0.001%. A 2023 rule adds 56 more, with lavender and lemon oils named outright.
Once a vial's open, its age matters too. Lavender's main compounds, linalool and linalyl acetate, react with oxygen and form hydroperoxides that sensitize skin, a 2016 study by Hagvall and Bråred Christensson explains. Of the patients they patch tested for a suspected contact allergy, 2.8% reacted to oxidized lavender oil.
How much essential oil do you add to a tallow balm?
Our calculator works by weight, so its ceilings are a share of what's in the bowl, whipped or not. Some oils carry a lower cap, which the calculator uses. Ylang ylang, rose otto, bergamot FCF and sandalwood are among them, with caps from Tisserand and Young's Essential Oil Safety. The calculator's two ceilings sit at the low end of Robert Tisserand's published ranges: 0.5 to 1.2% for facial cosmetics, 1 to 3% for body oils and lotions.
A dense 2 oz jar holds 56 g of balm. At the body ceiling, that's 0.56 g of essential oil, about 12 drops, and at the face ceiling it's 0.28 g, about 6. Droppers run 20 to 40 drops a milliliter, so a count is a guess. The calculator counts at 20. Under a gram of oil, a scale that reads 0.01 g is the better tool.
For a blend, the calculator has you pick oils from two or three note groups and give the middle note the biggest share. The whole blend still can't pass the ceiling. A 56 g body jar might take 0.37 g of lavender and 0.19 g of cedarwood. The tallow balm recipe calculator sizes the rest of a home batch, starting from four parts tallow to one part carrier.
Which citrus oils are phototoxic?
The National Association for Holistic Aromatherapy, NAHA, describes a phototoxic oil as one that can burn or darken skin once it's out in sun or UV light. Its list includes bergamot, expressed lemon, expressed lime and expressed bitter orange. NAHA's advice is to stay out of the sun and tanning booths for at least 24 hours after using one. IFRA, the fragrance industry's standards body, bans some materials and caps others. Robert Tisserand notes that IFRA's limit for lemon oil, which it set to avoid phototoxicity, is 2%.
Our calculator is stricter. It keeps every citrus oil off faces, and on the body it allows lemon only as a distilled oil and bergamot only as FCF. Sweet orange isn't on NAHA's list. An oxidized vial of it still sensitizes skin, so buy it small. A tallow balm doesn't screen UV, so a balm you'll wear in the sun should skip the phototoxic ones.
Who gets no essential oil?
There's a hard zero in our calculator for four groups: babies under two, pregnancy, nursing and reactive skin. Poison Control notes that children have thin skin and immature livers, which might make them more susceptible than adults, and it advises locking essential oils up. NAHA singles out peppermint and eucalyptus for caution around young children.
For pregnancy and nursing, the zero's our own caution. NAHA says there are no records of fetal harm from normal use of essential oils, though it still lists oils to avoid. Your OB or midwife has the say. It's cosmetic care, not a treatment, and your provider's plan comes first. For reactive skin, Tisserand's range is 0.2 to 1%, and the calculator still says zero because sensitization tends to stick. Once it happens, NAHA notes, it's likely to last for years.
People allergic to ragweed, chrysanthemums, marigolds or daisies are more likely to react to chamomile, the National Center for Complementary and Integrative Health says. If a scent's ever bothered your skin, a dermatologist can patch test you.
How do we scent our own jars?
Our jars don't follow the calculator, since research set the dose in each recipe. Four of our five recipes carry a CO2 extract. Moonlight Calm carries blue tansy at a studied dose, and Recovery Balm carries helichrysum. Frankincense shows up only as the CO2 extract in Velvet's Frankincense Edition, and our frankincense post explains that choice. The only Craft recipe numbers we print are Velvet's: 1% bakuchiol, 1.5% vitamin C.
No jar we sell holds a fragrance oil. If you'd like lavender without the bench work, our Bare Silk Lavender Edition carries lavender essential oil at a studied dose. For pregnancy or a baby's skin, I'd hand you Bare Silk Unscented, which carries none. It was our baby's first jar.
Start with Bare Silk ($34), five ingredients and sixty days to disagree.
Questions we hear
How many drops of essential oil should go in an ounce of tallow balm?
At our calculator's ceilings, an ounce of dense balm, about 28 g, takes up to 0.28 g of essential oil for the body, about 6 drops. A face balm takes half that, 0.14 g, about 3 drops. Droppers run 20 to 40 drops a milliliter, so it's worth weighing the oil on a scale that reads 0.01 g.
What essential oils are good for tallow balm?
For a home batch, lavender, frankincense, the chamomiles and cedarwood suit a face or body balm at our calculator's ceilings. Peppermint, rosemary, eucalyptus and the citrus oils stay on the body. The best pick is a scent you like, in a small vial you'll use up before it oxidizes.
Can I use essential oils in tallow balm while pregnant?
Our calculator's ceiling for pregnancy and nursing is zero, and that's our caution rather than a finding of harm. The aromatherapy association NAHA says there are no records of fetal harm from normal use of essential oils, though it keeps a list of oils to avoid. Ask your OB or midwife. We point pregnant readers to Bare Silk Unscented, which carries no essential oil.
Can babies have essential oils in tallow balm?
Our calculator says no: its ceiling for a baby under two is zero. Poison Control notes that children have thin skin and immature livers, which might make them more susceptible to an oil's effects than adults. Past two, your pediatrician has the say. For a baby's skin, we'd point you to Bare Silk Unscented, a five-ingredient balm without essential oil.
