What Is Di-C12-13 Alkyl Tartrate?
Di-C12-13 Alkyl Tartrate is an ester formed when tartaric acid is reacted with a blend of branched and linear fatty alcohols that have 12 to 13 carbon atoms. The result is a smooth, oil-like substance that is easily blended into creams and lotions. Its roots trace back to food science, where tartaric acid is common in grapes. Chemists noticed that pairing this natural acid with mid-length fatty chains created a mild, skin-friendly ingredient ideal for personal care. Over the past two decades suppliers have refined the process, using controlled esterification followed by filtration and vacuum distillation to ensure purity and a light skin feel.
You will spot Di-C12-13 Alkyl Tartrate in moisturizers, hydrating masks, lightweight anti-aging creams, eye lotions and leave-on treatment serums. Because it feels almost dry to the touch yet leaves a comfortable veil, formulators often choose it for modern “quick-absorb” products that promise softness without greasiness.
Di-C12-13 Alkyl Tartrate’s Cosmetic Benefits/Uses
In skin care formulas this ingredient plays a couple of key roles that boost performance and user experience
- Skin Conditioning – helps smooth the skin surface, leaving it feeling softer and more supple while supporting healthy moisture balance
- Emollient – fills in the microscopic gaps between skin cells which reduces roughness, improves spreadability of the product and gives a silky after-feel
Who Can Use Di-C12-13 Alkyl Tartrate
This lightweight emollient suits most skin types, including normal, combination, oily and sensitive skin, thanks to its fast-absorbing non-greasy finish. Dry skin can also benefit, though pairing it with a richer occlusive may be necessary for extra nourishment. It is not known to aggravate acne but individual responses can differ.
Di-C12-13 Alkyl Tartrate is produced from plant-derived fatty alcohols and tartaric acid, so it contains no animal substances and is considered appropriate for vegans and vegetarians.
No data show harmful effects for pregnant or breastfeeding women when used topically. The molecule is large, remains on the skin surface and is not linked to hormone disruption. This is not medical advice and anyone who is pregnant or nursing should confirm product choices with a healthcare provider.
The ingredient does not cause photosensitivity because it neither absorbs nor interacts with UV light, so standard daytime sun protection is sufficient. It is also fragrance free and gluten free, points that can matter for people with specific sensitivities.
Potential Side Effects/Adverse Reactions
Reactions to Di-C12-13 Alkyl Tartrate are rare, yet individual skin differences mean the following possibilities can occur.
- Mild burning or stinging in very sensitive skin
- Localized redness or itching in those allergic to tartrate compounds
- Temporary clogged pores when layered with heavier occlusives on oily skin
If you experience any persistent irritation discontinue use and seek advice from a qualified medical professional.
Comedogenic Rating
Rating: 1/5
Di-C12-13 Alkyl Tartrate is a mid length ester that sits lightly on the skin and is quickly absorbed. Its molecular structure is bulkier than simple fatty acids so it does not pack tightly inside pores. Published supplier data and anecdotal feedback show very few reports of pore blockage, especially when used in low to moderate concentrations typical of face creams.
Because of the low rating it is generally suitable for acne prone or breakout prone skin, provided the overall formula is also light and non occlusive.
No additional concerns have been flagged in the available cosmetic safety databases regarding its tendency to clog pores.
Summary
Di-C12-13 Alkyl Tartrate acts mainly as a skin conditioning agent and emollient. By filling microscopic gaps between skin cells it softens rough patches, improves spreadability and leaves a weightless silky finish that helps maintain moisture balance.
While not as famous as ingredients like squalane or glycerin it has been gaining quiet popularity among formulators looking for a fast absorbing alternative to heavier esters.
Current safety reviews classify it as low risk for irritation, sensitization or hormonal activity. As with any new skincare ingredient it is wise to perform a quick patch test when trying a product that contains it, especially if you have very sensitive or reactive skin.
