What Is Dibutyloctyl Malate?
Dibutyloctyl Malate is a lab made liquid ester created by joining malic acid, a fruit derived acid also known as hydroxybutanedioic acid, with a branched fatty alcohol called 2-butyloctanol. The result is a clear oil that feels silky, spreads easily and stays stable when heated or mixed with other ingredients. Chemists began exploring this material in the late 1960s as a safer flexible agent for nail polish and soon noticed its smooth feel was useful in skin care and makeup. Today manufacturers produce it through a controlled esterification process: malic acid is reacted with the alcohol under heat while removing water, then the mixture is purified to meet cosmetic grade standards.
You are most likely to see Dibutyloctyl Malate in creamy or oily formulas where a soft, cushiony finish is wanted. Typical products include lipsticks, lip balms, liquid foundations, primers, pressed powders, sunscreens, hand and body lotions, leave-on hair conditioners and nail treatments.
Dibutyloctyl Malate’s Cosmetic Benefits/Uses
This multitasking ingredient offers several perks to both the formula and the user
- Plasticiser: It softens brittle film formers such as those in nail polish or long wear makeup so the dried layer flexes with movement instead of cracking
- Skin Conditioning: It leaves a light, non-greasy film that smooths rough spots and improves overall feel making skin look more even
- Emollient: Its oily nature fills in tiny gaps between skin cells helping to lock in moisture and give an immediate sense of softness
- Solvent: It can dissolve pigments, UV filters and other oil soluble actives allowing for stable uniform blends and better color payoff
Who Can Use Dibutyloctyl Malate
Dibutyloctyl Malate suits most skin types, including dry, normal and combination, because it is lightweight yet still provides a silky occlusive layer. Oily and very acne prone skin can usually tolerate it as well since it is less greasy than many traditional oils, though extremely sensitive or congestion-prone individuals may prefer to monitor their skin for any heaviness.
The ester is made entirely from synthesized malic acid and a plant-derived fatty alcohol, with no animal sourced materials or by-products, so it is considered vegan and vegetarian friendly.
No data indicates that Dibutyloctyl Malate poses a specific risk to women who are pregnant or breastfeeding when used topically in cosmetic amounts. This is not medical advice and expectant or nursing mothers should discuss any product containing it with their healthcare provider to be safe.
The ingredient does not increase photosensitivity, so it will not make skin more likely to burn in the sun. It also plays well with most other common cosmetic ingredients and is odorless, which makes it unlikely to interfere with fragrance sensitivities.
Potential Side Effects/Adverse Reactions
Side effects from topical use of Dibutyloctyl Malate vary from person to person. The following is a list of potential reactions, though they are uncommon when the ingredient is used at typical cosmetic levels.
- Mild skin irritation such as redness or itching in highly sensitive individuals
- Allergic contact dermatitis in the rare case of a true allergy to the ester
- Transient eye stinging if the product accidentally gets into the eyes
- Clogged pores or small breakouts on very acne prone skin when used in heavy formulations
If any of these effects occur stop using the product and seek advice from a medical professional.
Comedogenic Rating
Rating: 1/5. Dibutyloctyl Malate is a branched, mid-weight ester that sits lightly on the skin and has good spreadability, so it is much less likely to block pores than heavier straight-chain oils or waxes. Formulators typically use it at low to moderate levels, further reducing clogging risk. Those prone to acne or breakouts can usually use products containing this ingredient without major concern, especially when the overall formula is lightweight. Very occlusive or heavy blends could still be an issue for some users, so texture and total oil load matter.
The rating may vary slightly depending on the companion ingredients and the total oil phase. When paired with highly comedogenic oils or in thick balms the final product could feel heavier than the ester alone would suggest.
Summary
Dibutyloctyl Malate functions as a plasticiser, skin conditioner, emollient and solvent. Its flexible molecular structure softens rigid films in nail and makeup products; its silky oil texture fills surface gaps to smooth and moisturise; and its solvency power helps disperse pigments and oil-soluble actives evenly.
While not a headline star like hyaluronic acid or vitamin C, this ester enjoys steady use behind the scenes in lipsticks, foundations, sunscreens and nail lacquers because it quietly improves feel and wear without adding greasiness.
Current safety data show it is well tolerated with low irritation potential and minimal comedogenicity, making it suitable for most skin types. As with any new cosmetic, it is wise to perform a small patch test when first trying a product that contains Dibutyloctyl Malate just to be safe.
