Ethylhexyl Palmitate

Overview

Ethylhexyl palmitate (sometimes labelled octyl palmitate) is an ester made from palmitic acid (a common fatty acid from palm or coconut) and 2-ethylhexanol. It is a clear, water-thin, almost odourless liquid with a remarkably light feel.

It belongs to the same general family as C12-15 alkyl benzoate and isopropyl myristate, and it does much the same job: providing slip and a fast-absorbing skin-feel without contributing scent, colour, or perishable fat. It is one of the cheapest emollient esters on the market, which is why you see it as a major component of mass-market body lotions, makeup removers, and primers.

Shelf life is 2-3 years. Like other synthetic esters, it does not oxidise the way plant oils do.

What it does in a formula

Three roles:

1. Light, dry emollient feel — it spreads thin and absorbs fast, contributing slip but no residue
2. Solvent for waxes and pigments — it dissolves makeup pigments, waxes, and some active oils cleanly
3. Makeup remover base — it dissolves oil-based makeup (mascara, foundation, sunscreen) and rinses off cleanly with surfactants

It does not deliver skin-care benefits on its own. It is a vehicle. The reason it shows up in so many formulas is that it is cheap, reliable, and disappears into the finished product without changing its character.

How to use

Add to the oil phase. Heat-stable up to 100 C — you can run it through emulsification at 70-75 C without trouble.

Usage rates by product type:

• Body lotions: 3-10%
• Face creams: 2-6% (it is light enough not to feel heavy, but other esters give a slightly better dry-touch finish)
• Makeup primers: 5-15%
• Cleansing oils and makeup removers: 20-70% (often the main component)
• Lipsticks and lip glosses: 5-30%
• Eye makeup removers: 50-90%
• Sunscreen (chemical filters): 5-20% as solvent

For a balm-style cleansing oil, 50-70% ethylhexyl palmitate + 20-30% caprylic/capric triglyceride + 5-10% polysorbate 80 (so it rinses) is a workhorse recipe.

Best for / Worst for

Best for: budget body lotions, cleansing balms and oils, makeup removers, lip glosses, makeup primers, sunscreen vehicles, kid-friendly body products (it is exceptionally well-tolerated and bland).

Worst for: acne-prone skin (it is mildly comedogenic for some users, more so than coco-caprylate or isoamyl laurate), products positioned as fully natural (synthetic ester), high-end face creams where you want a more luxurious feel.

Common pitfalls

Comedogenicity. Ethylhexyl palmitate has a mild comedogenicity rating in the literature. Most people tolerate it fine, but if you formulate for acne-prone skin, use a lower-risk ester like coco-caprylate or isoamyl laurate.

Mistaking it for an “active.” It is structural. Removing it does not lose any skin-care benefit, but it will change the texture noticeably.

Confusing ethylhexyl palmitate with cetyl palmitate. Cetyl palmitate is a wax, solid at room temperature. Ethylhexyl palmitate is a liquid ester. They behave nothing alike.

Using it in lip products with a sticky base. Ethylhexyl palmitate can be slightly draggy on lips at high rates (over 30%). For glosses, blend with a stickier ester like polyisobutene or a sucrose ester.

Substitutes

• C12-15 alkyl benzoate — drier finish, slightly better skin-feel, similar price.
• Coco-caprylate — plant-derived, better for acne-prone skin, similar light feel.
• Isoamyl laurate — plant-derived, slightly more cushioning.
• Isopropyl palmitate — almost identical chemistry, slightly cheaper, a touch more comedogenic.
• Caprylic/capric triglyceride — heavier and more conditioning, loses the dry-touch feel.
