What Is Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate?
Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate is a lab-made ester that joins a lightweight solvent, ethoxydiglycol, with a plant-derived cyclohexane dicarboxylic acid. The pairing gives the molecule a balanced mix of water-loving and oil-loving parts, allowing it to sit comfortably in many kinds of cosmetic formulas. First developed in the early 2000s as chemists searched for gentle alternatives to heavier oils, it soon found a place in skin and hair care because of its silky feel and ability to lock in moisture without greasiness.
Manufacturing begins with fermentation-sourced diglycol, which is reacted with ethylene oxide to form ethoxydiglycol. This is then esterified with purified cyclohexane-1,4-dicarboxylic acid using food-grade catalysts. The final liquid is clear, odorless and low in viscosity, making it easy to blend at room temperature.
You will spot this ingredient most often in leave-on moisturizers, lightweight serums, hydrating gels, sheet masks, anti-aging creams, priming lotions and hair conditioners. Its versatility also makes it popular in sunscreens where a smooth, nongreasy finish is key.
Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate’s Cosmetic Benefits/Uses
This multitasking ingredient supports a formula in several ways
- Emulsion stabilising – helps keep water and oil phases from separating which means creams stay smooth and effective for longer
- Hair conditioning – forms a thin film along the hair shaft for added softness and easier detangling without weight
- Humectant – attracts water from the air and holds it on the skin surface maintaining hydration over time
- Skin conditioning – leaves skin feeling supple and silky improving overall texture and comfort
- Emollient – fills tiny gaps in the skin’s surface giving an immediate smooth feel and helping to reduce moisture loss
Who Can Use Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate
This lightweight ester suits most skin types including oily, combination, normal and dry because it hydrates without leaving a greasy film. Its low viscosity and non occlusive nature make it comfortable even for sensitive or acne-prone skin, as it will not clog pores or create heavy buildup.
The ingredient is manufactured from plant sourced and synthetic inputs with no animal derived materials so it is considered suitable for both vegetarians and vegans.
No data suggest any specific risks for women who are pregnant or breastfeeding when the ingredient is used topically at the low levels found in finished cosmetics. This is not medical advice and anyone who is expecting or nursing should review any skincare product with a qualified health professional to be on the safe side.
Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate is not known to cause photosensitivity and does not degrade when exposed to sunlight. It can be worn comfortably under sunscreen or makeup.
Potential Side Effects/Adverse Reactions
Responses to topical Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate differ from person to person. The following points outline possible but uncommon side effects assuming the ingredient has been formulated and preserved correctly. Most users will not encounter these issues.
- Mild skin irritation such as tingling or warmth shortly after application
- Temporary redness or flushing in very sensitive skin
- Rare allergic contact dermatitis presenting as itching or small bumps
- Eye irritation if the product accidentally gets into the eyes
- Increased absorption of strong actives applied at the same time which could amplify their own side effects
If any discomfort or persistent reaction occurs stop using the product and seek guidance from a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 0/5. Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate is a light ester that spreads quickly then evaporates or absorbs without forming a waxy or oily film. Its molecular weight is low and it does not linger in pores so it does not encourage the buildup of dead cells or sebum that can trigger comedones.
Because it is essentially non occlusive and non greasy this ingredient is considered suitable for skin that is prone to acne or breakouts.
No data indicate that it interacts with other common ingredients in a way that would raise the comedogenic risk, though pairing it with very heavy butters or waxes could offset its lightweight character.
Summary
Bis-Ethoxydiglycol Cyclohexane 1,4-Dicarboxylate serves as an emollient, humectant, skin and hair conditioner and an emulsion stabiliser. Its balanced water-loving and oil-loving structure lets it sit at the interface of a cream where it draws in moisture, smooths rough edges on skin or hair and helps keep the formula from separating.
The ingredient is not as famous as hyaluronic acid or glycerin yet formulators value it for delivering a silky finish without heaviness so it often appears in newer lightweight serums sunscreens and leave-in hair products.
Overall safety data are strong with irritation or allergy reported only rarely at the low levels used in cosmetics. While the risk is low it is always smart to patch test any new product to confirm personal compatibility.
