Squalane or jojoba oil: which is better for skin and balms?

Squalane has no double bonds; jojoba's iodine value is 81. Squalene, the sebum lipid, oxidised worst against jojoba at 60 C. Weight, cold and the 39% claim.

Squalane is the lighter and, on chemistry, the more stable of the two; jojoba is the closer match to a real class of sebum lipid, and a liquid that barely oxidises in its own right. The question is muddled by one letter. The lipid human skin makes is squalene, C30H50, with six double bonds, and it is the one that goes off: in a 2022 study that heated jojoba oil, olive oil and squalene at 60 C for 60 days, jojoba had the lowest peroxide and carbonyl values, its acid value did not change, and squalene's acid value rose about 39 times. Squalane, C30H62, is squalene with every double bond hydrogenated away. It is not the sebum lipid, and nobody in that study tested it. Choose squalane for a dry, fast finish and a liquid that stays clear in a cold room; choose jojoba for a fuller, longer-lasting film, knowing it is already the most stable plant oil in most tests.

• Squalane: C30H62, no double bonds
• Squalene: C30H50, the sebum lipid
• Jojoba: 97% wax esters, iodine value 81
• Sebum: 25% wax esters, 12% squalene
• Viscosity: 25-35 against 37.7-50 mPa s
• "39% better": no method given

The two liquids, measured side by side

The first screen of results for this question is product listings and brand copy, with no measured numbers, and no source we found compares the two on more than one property. The table assembles the figures that do exist, from six sources and the specification bands on our own squalane page.

Three rows decide most choices: double bonds, which is why squalane needs no antioxidant; viscosity and cold, which is why it feels lighter and stays clear in winter; and sebum, where the marketing for both lives and the confusion starts. Jojoba's own composition is set out on the jojoba oil page.

Squalene or squalane: the one letter that matters

Squalene is a triterpene hydrocarbon, C30H50, with a molecular weight of 410.7 and six carbon to carbon double bonds. Human skin makes it, and it is a large share of the oil on the skin's surface. Pappas's 2009 review of epidermal surface lipids puts it at a mean of 12 percent of sebum and notes that its accumulation in sebum is "uniquely high (∼12%) compared to the levels of any other tissue or organ". Squalane is the same 30 carbon skeleton with twelve hydrogen atoms added, C30H62, molecular weight 422.8, and no double bonds at all.

Those double bonds are where oxidation starts, so the two behave in opposite ways in a jar. Squalene's theoretical iodine value is about 381; squalane's is below 1. The chain reaction that turns an oil rancid starts at a hydrogen next to a double bond, as set out in rancidity and oxidation. Squalene is full of those positions. Squalane has none.

The sources do not blur the two. The squalane data sheet we read says it plainly: "The squalene molecule is one of the main components of human sebum. Its hydrogenated form, squalane C30H62, is recognized as a high quality and high-performance emollient". Pappas lists squalene in sebum and gives no figure for squalane. The 1982 Cosmetic Ingredient Review report states in its abstract that "Squalane and Squalene have been identified as natural components of human sebum", but gives no amount for either, and every quantified figure in the sources here is for squalene.

Why the swap persists

It persists because it sells. The brand blog behind the "39 percent" claim, discussed below, opens with "The human body produces its own version of squalane", and then says the amount "decreases over time". What the body produces is squalene. Calling the bottle by the skin's own lipid lends squalane a biological story that belongs to a different molecule, and one letter is easy to miss.

The swap also hides an irony. If the selling point were really "the same as your own sebum", the matching ingredient would be squalene itself, and squalene is the one that oxidises. Pappas notes "possible roles of squalene oxidation products on UV protection but also irritation", and that "these products, together with unsaturated free fatty acids, have been reported to be comedogenic." Squalane is valuable precisely because it is not the sebum lipid but a stable stand-in for one: a good reason to use it, and a different one from the label's.

Which is more stable: what was actually measured

On chemistry, squalane wins outright: with no double bonds it has nothing for oxygen to attack. But no source we found ran squalane and jojoba through the same oxidation test, so there is no measured margin between them. What exists is a direct test of jojoba against squalene, the unsaturated parent, and data showing jojoba outlasting almost every other plant oil.

The 60 C test. Tsuchimoto, Sakai and Fukui, in BPB Reports in 2022, put 100 g of each oil in a 200 mL beaker and held it at 60 C for 60 days: crude and refined jojoba, crude and refined olive oil, and purified squalene from a chemical supplier. An outside laboratory, Japan Food Research Laboratories, measured acid, peroxide and carbonyl values before and after. The results, in the authors' words:

Squalene's peroxide value ended below olive oil's, which could be misread as squalene doing better. The authors explain why it is not: the peroxide value "finally decrease[s] as lipid oxidation progresses", because the peroxides themselves break down into the carbonyls and acids where squalene led. Their conclusion is that "autooxidation was more pronounced in squalene", and that jojoba "is the most stable to autooxidation among these three investigated oils."

Jojoba against other oils. The same paper measured the induction period of 20 jojoba oils by a weighing method, the number of days at 60 C until the oil's weight rose by 0.5 percent. Crude jojobas ran from 51.3 to 220.0 days, refined jojoba 228.7 days, and a deodorised oil 131.3. By the same method, the authors' earlier work found 23 other oils, almond, argan, corn, cottonseed and sunflower among them, at 1.0 to 29.0 days. The shortest crude result, 51.3 days, came from a bottle bought in 2017 and kept "in a translucent plastic bottle for four years". In a Rancimat test at 100 C and 20 L of air per hour, Fagoaga and colleagues measured jojoba at 39.80 hours, against 27.50 for olive, 10.39 for sunflower and 4.45 for rosehip. How jojoba compares with a common triglyceride oil in more detail is on the jojoba against sweet almond oil page.

Reading the two together. The 60 C result shows jojoba is far more stable than the sebum lipid squalane is named after. It cannot rank jojoba against squalane, which was not in the beakers. The case for squalane rests on its specification, an iodine value below 1, and on supplier shelf lives such as the 24 months unopened on the Senso-OLIVE SQ data sheet. In a balm, the other oils will set the shelf life long before either of these does.

Because squalane has nothing to oxidise, tocopherol added to a squalane-heavy balm protects only the other oils, and squalane does not slow the oxidation of anything blended with it. The least stable oil sets the pace, which the oil blend calculator models, and where an antioxidant earns its place is covered in vitamin E and antioxidants. No stability figure here converts into months on a shelf; dating a finished product is a separate test, set out in shelf life testing.

Which is lighter

Squalane, by every measure we have, though by less than its reputation suggests. Its specification band for viscosity at 25 C is 25 to 35 mPa s. The CIR's jojoba report quotes two figures: 37.7 mPa s from one rheology study and 50 cP from a table of jojoba's physical properties. So squalane runs from about the same as jojoba to half as thick, depending on the figures compared. It is also less dense, 0.807 to 0.812 g/mL against 0.87, so a millilitre of squalane weighs about 7 percent less, which matters if you measure by volume.

The bigger difference is in the finish, not the bottle. Squalane is a hydrocarbon with no ester groups, so it has almost no polarity and leaves very little perceptible film; jojoba leaves a thin, cushioned one that lasts. Why a liquid's viscosity and its finish are different things is set out in balm texture science. If the complaint about a balm is the greasy film still there twenty minutes after application, substituting a few percent of squalane for jojoba or another liquid oil is the targeted fix, for the reasons in greasy heavy afterfeel.

Cold is where they really part. Jojoba's freezing point is 9 C in the CIR's table of physical properties, and a balm or a bottle of jojoba left in an unheated workshop or a winter delivery van can turn cloudy or solid. It recovers on warming, but a clear face oil that arrives cloudy looks spoiled. Squalane's pour point is below minus 30 C, so it stays clear and fluid in any condition a balm will meet. For a clear oil or a product shipped in winter, that is a stronger argument for squalane than its feel.

Which is closer to sebum

Neither is sebum, and each matches a different piece of it. Pappas's table of sebum composition gives the shares, with a caution that "the relative composition of sebum depends on the sampling method used":

Read it two ways and you get two answers. By class, jojoba is closer: wax esters are about a quarter of sebum, twice the share of squalene, and jojoba is nearly all wax ester. It is a match of class: jojoba's esters are mostly C20 and C22 chains, and no source here compares them molecule by molecule with sebum's. By molecule, squalane is closer to one specific sebum lipid, being one hydrogenation step from squalene. But that step is the whole difference between a lipid that oxidises readily and one that does not, so "identical to skin's own oil" is wrong for squalane in exactly the way that matters.

Either match is chemistry, not effect. None of the sources here shows that matching a sebum lipid makes an ingredient better tolerated, faster absorbed, or able to regulate oil production. The boundary between a cosmetic description and a therapeutic claim is set out in cosmetic vs drug claims.

The "39% better at cell turnover" claim

The one number that appears when you search this comparison comes from a squalane brand. Biossance's blog post "#OilWars: Squalane Vs Argan Oil And Jojoba Oil", by Christine Tusher and dated 20 March 2017, states: "Squalane is 53% better at accelerating cell turnover than argan oil, 39% better at accelerating cell turnover than joboba oil", the misspelling being the post's. It presents these as "our scientists' findings". An infographic repeats them as large type beside pairs of bars.

The page gives no method, no study and no citation. It does not say whether the test used skin or cultured cells, how "cell turnover" was measured, what dose was applied for how long, how many samples were involved, or what "39% better" is 39 percent of. The infographic's bars have no axis, no units and no labels. We searched for a published study behind the figure and found none; search results for it return the blog post itself. Until one appears, the number is a marketing statement, and this page does not treat it as a measured difference between squalane and jojoba.

A maker who repeats the figure on a product is repeating a claim they cannot substantiate, about a change in how skin functions, which is drug claim territory.

Skin tolerance and use levels

Squalane. The 1982 Cosmetic Ingredient Review report covered squalane and squalene together. Its abstract records that both were used in cosmetics at "0.1 to > 50%", that both are "nonirritants to rabbit skin and eye at 100% concentration", and that "formulations containing Squalene indicate it is not a significant human skin irritant or sensitizer". It concluded that "both Squalane and Squalene are safe as cosmetic ingredients in the present practices of use and concentration." The human data in the abstract are for squalene-containing formulations; the 100 percent results are on rabbits. The Senso-OLIVE SQ data sheet recommends 1 to 10 percent and describes the material as non-sensitising and non-irritating.

Jojoba. The 2008 CIR assessment reports that "in clinical tests, Simmondsia Chinensis (Jojoba) Seed Oil was neither a significant dermal irritant, nor a sensitizer", and judged it safe "at concentrations up to 100% in body and hand creams". Reported uses rose from 188 in 1989, at up to 25 percent, to 1,123 in 2007, at up to 100 percent. In rabbit eyes the oil was "non- to slightly irritating".

Pores. Neither the 2008 report nor the 1982 abstract gives a comedogenicity result for jojoba seed oil or for squalane. The CIR jojoba report's "moderately comedogenic" result in rabbits is for jojoba seed wax, a different ingredient, and should not be quoted for the oil. What the rating scales can and cannot predict is covered in comedogenic ratings. One structural point is solid: squalane is a hydrocarbon and supplies none of the fatty acids that Malassezia yeasts feed on, while jojoba is built from fatty acids and fatty alcohols. That is why squalane stays in a formula built for that constraint, as set out in malassezia safe balms.

Does either go deeper into skin?

Jojoba has been measured and squalane has not. The in vivo studies collected on the lipid penetration page placed neat jojoba in the upper layers of the stratum corneum, the dead outer layer, alongside the other oils tested. None of them tested squalane, so this page gives no depth for it. Squalane's molecular weight, about 423 daltons, is under the 500 dalton line that page discusses and jojoba's main esters, about 590 to 620, are over it, but that page also explains why being under 500 does not by itself mean a molecule is absorbed. "Squalane sinks in" describes a dry finish, not a measured depth.

Buying either one

Squalane. Ask for the assay, the iodine value, the peroxide value and the source in writing. The INCI name is Squalane whether it came from olives, sugarcane fermentation or shark liver, so a plant or vegan claim rests on the supplier's declaration, not the label, as covered in vegan and cruelty-free labels. Read the data sheet carefully. The Senso-OLIVE SQ sheet we used lists "Squalane and derivates (%) 97 max.", which reads like a minimum printed as a maximum; a figure like that is a question to put to the supplier before a purchase, not after. The same sheet gives a 24 month shelf life unopened, in a cool dry place.

Jojoba. Golden, crude jojoba carries more of the minor components behind its antioxidant activity; in the 60 C study refined jojoba had the longest induction period but by far the lowest antioxidant activity by the L-ORAC method, 31.2 against 402.5 to 2,795.6 micromol Trolox equivalent per litre for the crude oils. Composition "varies with maturity of the seeds and somewhat with location and climate", in the CIR's words, so ask for the lot's certificate. Store it in amber glass or a closed metal container: the crude jojoba with the shortest induction period in the 60 C study was the one kept four years in translucent plastic. Questions to put to any supplier are listed in sourcing ingredients.

Which to choose for which product

The two work well together. A face balm that uses jojoba as its main liquid and replaces 5 percent of it with squalane keeps jojoba's cushion and loses much of the lingering film. A worked starting point is in face balm, and a lip formula built on jojoba is in how to make lip balm.

What these numbers do not settle

Stability. No source here tested squalane and jojoba side by side. The 60 C study compared jojoba with squalene, and the company link of two authors is declared in the paper. Squalane's advantage is inferred from its iodine value, which is a specification, not an ageing test. Treat "squalane is more stable" as true on chemistry and unmeasured as a margin.

Sebum. Pappas's figures are means and ranges from a review, and the review warns that sampling method changes them. The CIR 1982 abstract says squalane has been identified in sebum but gives no quantity; every figure we hold is for squalene.

Viscosity. The squalane figures are a specification band and the jojoba figures come from two studies quoted by the CIR. The direction is consistent; the size of the gap is not fixed.
