What Is Dimethylolcyclohexane Dibenzoate?
Dimethylolcyclohexane Dibenzoate is a synthetic ester created by reacting dimethylolcyclohexane with benzoic acid. The process joins the alcohol groups of dimethylolcyclohexane to the carboxylic groups of benzoic acid, forming a stable molecule that behaves as a plasticiser. Because it is lab made rather than plant derived, its quality and purity can be tightly controlled, which is important for cosmetics. The ingredient first appeared in industrial coatings where flexibility and crack resistance were needed, then formulators noticed it could deliver the same benefits to beauty products. Today you might spot it in nail polishes, mascaras, flexible hold hair sprays, peel-off face masks and some long-wear foundations that need to stay smooth and resist flaking.
Dimethylolcyclohexane Dibenzoate’s Cosmetic Benefits/Uses
In cosmetic formulas this ingredient serves a single, focused purpose.
As a plasticiser, Dimethylolcyclohexane Dibenzoate softens and increases the flexibility of polymer films formed by ingredients like acrylates. This added flexibility helps prevent cracking or peeling in products such as nail enamel, mascara and certain face masks. It also improves spreadability so the product applies in a thinner, more even layer, giving a smoother finish and better wear time.
Who Can Use Dimethylolcyclohexane Dibenzoate
This plasticiser is considered skin neutral, meaning it neither hydrates nor dehydrates, so it can generally be used on dry, oily and combination skin without concern. Sensitive skin types usually tolerate it well because it stays locked inside the film it helps create rather than sitting freely on the skin’s surface.
Dimethylolcyclohexane Dibenzoate is fully synthetic and contains no animal derived substances, making it suitable for both vegans and vegetarians. It is also cruelty free when sourced from manufacturers that do not test on animals.
Current safety data show no specific risks for pregnant or breastfeeding women when the ingredient is applied topically in the low amounts found in cosmetics. This is not medical advice, and anyone who is pregnant or nursing should confirm product choices with a healthcare professional to be safe.
The molecule itself is not known to make skin more sensitive to sunlight, so normal sun precautions are sufficient when using products that contain it.
Potential Side Effects/Adverse Reactions
Side effects and reactions to topical Dimethylolcyclohexane Dibenzoate differ from person to person. The points below outline potential issues only, and most users will not experience them when the ingredient is correctly formulated in a product.
- Mild skin irritation – rare itching or redness, more likely on already compromised skin
- Allergic contact dermatitis – uncommon sensitivity in people allergic to benzoates or related chemicals
- Eye irritation – stinging or watering if the ingredient accidentally gets into the eyes from products like mascara or hairspray
- Respiratory discomfort – coughing or throat irritation if inhaled from aerosol sprays containing high concentrations
If any of these reactions occur, discontinue use and seek medical advice.
Comedogenic Rating
Rating: 0 / 5
Dimethylolcyclohexane Dibenzoate is a large, non-oily molecule that stays trapped within the dry film it helps create rather than sitting on the skin surface and clogging pores. Because it does not add extra oils or waxes to a formula, it has no record of triggering blackheads or breakouts.
This makes it suitable for people who are prone to acne or frequent breakouts.
Keep in mind that the overall comedogenicity of a finished product also depends on the other ingredients in the formula, not just this plasticiser.
Summary
Dimethylolcyclohexane Dibenzoate is used in cosmetics as a plasticiser. It softens polymer films, boosts flexibility and helps products like nail polish, mascara and peel-off masks apply smoothly and resist cracking.
It is not a household name like hyaluronic acid or glycerin, so you will mainly see it in specialised long-wear or flexible film products rather than in everyday creams and lotions.
Current safety data show it is well tolerated on most skin types with very low risk of irritation or pore clogging. As with any new product, patch testing is a smart step before full use.
