Clary Sage Body Butter: Why We Skip the Lotion

If you are choosing between a whipped body butter and a lotion scented with clary sage oil, our advice is to make the butter and skip the lotion. The deciding factor is water: a lotion contains it, and so needs a preservative system that is the job of a cosmetic chemist, while a butter is built from fats and oil only. This page walks through that decision, works the oil dose out by weight for a 100 g jar, and says what you take on if you give the jar away or sell it.

Butter or lotion: the water question

FDA's small-business guidance for homemade cosmetics begins with responsibility: "If you manufacture or market cosmetics, you have a legal responsibility for the safety and labeling of your products." On microbes it says cosmetics "do not have to be sterile, but they must not contain any harmful microorganisms" (FDA, Small Businesses & Homemade Cosmetics: Fact Sheet). That is the rule you are under, and it is why the water in a lotion matters.

We could not retrieve a primary source that quantifies microbial risk in waterless butters, so the following is reasoning, not a finding. A lotion is an emulsion of oil and water, and microbes need water. A butter with no water phase offers them far less. Reasoning from that, the practical consequence is that a lotion made at home with tap water and no tested preservative is the riskier project, and we do not give a lotion recipe. If you want a lotion, buy a base that comes already preserved from a supplier and add oil to it at the dilution below. We sell none, only the two clary sage oils. Do not read "no water" as "cannot be contaminated." A 2026 review in Frontiers in Microbiology (Iskandar, Marchin and Roques) found contamination of 2% to 100% across home-use products it examined, with Pseudomonas aeruginosa, Enterobacter, Staphylococcus aureus and fungi the usual culprits. It studied mascara, lipstick, eyeliner and similar items, not butters, so applying it to a jar is an inference. The consequence we draw is hygiene: a clean spoon or spatula, not a wet finger, and keep water out of the jar in the shower and at the sink.

The oil dose, worked by weight

Butters are weighed, so the dose is easier in grams. The Tisserand Institute's drop-size page reports that 20 drops weighed 0.66 g in three studies, which is about 0.033 g per drop, or about 30 drops per gram. Its dilution guide gives 1% to 3% for body oils and lotions; our pages say 0.5% to 2% in a carrier before the oil touches skin. We cap at 2%, and that is our reasoning from a 2024 EFSA panel opinion that clary sage oil should be considered a skin and eye irritant and dermal and respiratory sensitiser (written for animal feed use, no dermal dose assessment).

200 g1 g (about 30 drops)2 g (about 60 drops)4 g (about 120 drops)

The drop count is the weak link. The same page found 20 to 40 drops per ml across droppers, so a drop count can be off by a third or more in either direction. Weighing the oil on a scale that reads to 0.01 g avoids that; this is our reasoning, not a sourced guideline. Our oils are sold undiluted, so the weighing is yours. Patch test the finished butter (see how to patch test clary sage oil); we have not made it, and the numbers above are arithmetic, not a tested recipe.

Choosing the butter, and what we could not verify

We sell no butters or carrier oils, so what follows is about shea, the one we could source. A 2023 study in Foods (Abdel-Razek and colleagues) analysed crude shea butter, refined shea stearin, refined olein and a 1:1 mix. Stearic and oleic acid were the two main fatty acids. Refining and fractionation changed peroxide value, tocopherol and sterol content, and the authors measured antioxidant activity in a laboratory, not on skin. The practical consequence is that "shea butter" on a label can mean a different material from supplier to supplier, so ask for a technical data sheet.

We could not verify melting ranges or whipping temperatures for shea or cocoa butter from a primary source this session, so we give none. Take them from your supplier's data sheet and treat any number on a recipe blog with the same caution. One piece of reasoning is worth stating: the oil is a volatile, heat-sensitive ingredient, so we would add it after the melted butter has cooled to near the temperature at which it starts to set, not into hot liquid. That is our logic, untested. For carriers to blend in, see the carrier oil guide.

Shelf life: the butter ages, and so does the oil

Oxidation is the limiting factor. The Hagvall and Christensson patch-test study (Acta Dermato-Venereologica, 2016) reported that linalool and linalyl acetate, the main components of lavender oil, autoxidize in air to sensitizing hydroperoxides, and that 2.8% of consecutively tested dermatitis patients reacted to oxidized lavender oil. That study used lavender, in a clinic, so applying it to clary sage in a jar is an inference; but the EFSA opinion lists the same two compounds at 55% to 78% and 6.5% to 25% in clary sage oil. Our pages give a typical shelf life of 2 to 3 years for the Botanical oil and 3 to 4 years for the Purity oil when tightly capped away from heat and light. A jar you open every day and dip a spoon into is not kept that way, so label it with the date, make it in small jars, and discard it if the smell changes or the surface looks different. Do not carry it in a hot car.

If you give it away or sell it

FDA's cosmetics labeling guide says a label must carry an identity statement and net quantity, the name and business address of the manufacturer, packer or distributor, and ingredients "in descending order of predominance," with those at 1% or less allowed in any order after the larger ones. A warning is required where needed to prevent a health hazard. The ingredient declaration is tied to products sold at retail, with exceptions for free samples. The guide does not say whether the other rules apply to gifts, so ask FDA, or a regulatory consultant or attorney, before you sell. FDA's fact sheet adds that the firm named on the label must ensure adequate substantiation of safety. Our pages make no health claims, and neither should a jar: no promises about skin.

Who should skip this

Our pages say to avoid clary sage oil during pregnancy and to keep it away from children and pets. Ask an OB-GYN or midwife, a pediatrician, or a veterinarian. Eczema, a rash or broken skin belongs with a dermatologist, not a jar of butter. Because the oil is, in our words, "unusually relaxing to sit with," do not put it on and drive. For a use on a different schedule, see the bath oil article, and for the dilution fundamentals, how to dilute clary sage oil.
