What Is Di-C14-15 Alkyl Tartrate?
Di-C14-15 Alkyl Tartrate is an ester made from tartaric acid, a natural compound most often sourced from grapes, and a blend of mid-length fatty alcohols with 14 to 15 carbon atoms. When chemists react tartaric acid with these alcohols they create a silky, oil-like ingredient that feels light on the skin. Although tartaric acid has been known for centuries as a by-product of wine making, its esterified forms such as Di-C14-15 Alkyl Tartrate began gaining attention in cosmetics in the late 1990s when formulators looked for plant-derived alternatives to mineral oils and silicones. The production process starts with purified tartaric acid which is combined with fatty alcohols under controlled heat and vacuum until water is removed and the new ester forms. The result is a clear or slightly yellow liquid with a smooth skin feel. You will typically find Di-C14-15 Alkyl Tartrate in moisturizers, anti-aging creams, primers, masks and lightweight facial oils where it helps improve texture and softness.
Di-C14-15 Alkyl Tartrate’s Cosmetic Benefits/Uses
This ingredient adds more than a pleasant feel to a formula. Its main roles are:
- Skin conditioning – helps keep skin feeling soft and supple while supporting a healthy looking surface
- Emollient – forms a thin layer that smooths rough patches and enhances spreadability giving products a luxurious slip without a greasy after-feel
Who Can Use Di-C14-15 Alkyl Tartrate
Thanks to its lightweight silky texture Di-C14-15 Alkyl Tartrate suits most skin types, from dry and normal to combination and even oily skin that dislikes heavy oils. Those with very sensitive or compromised skin generally tolerate it well because it has a low irritation profile, though individual responses can vary.
The ingredient is typically sourced from plants such as grapes and coconut or palm derived fatty alcohols, so products using it can be formulated to meet vegan and vegetarian standards. Checking each brand’s sourcing policies will confirm there are no animal based additives elsewhere in the formula.
Current safety data points to low systemic absorption, so topical use while pregnant or breastfeeding is not expected to pose a risk. This is not medical advice and anyone who is pregnant or nursing should review their skincare routine with a healthcare professional before starting new products.
Di-C14-15 Alkyl Tartrate is not known to cause photosensitivity and does not require additional sun protection beyond the daily SPF already recommended.
Potential Side Effects/Adverse Reactions
Side effects from topical use of Di-C14-15 Alkyl Tartrate differ from person to person. The points below cover potential, not guaranteed, reactions and most users will not experience them when the ingredient is properly formulated.
- Mild skin irritation such as redness or itching
- Allergic contact dermatitis in individuals sensitive to tartaric acid derivatives
- Temporary breakouts for acne prone users if the rest of the formula is overly rich
- Stinging or watering if the product accidentally gets into the eyes
If any unpleasant reaction occurs stop using the product and consult a qualified healthcare professional for guidance.
Comedogenic Rating
Rating: 2 out of 5. Di-C14-15 Alkyl Tartrate is built from mid length fatty chains but the tartaric backbone keeps the overall molecule light and less likely to clog pores than heavier plant butters or waxes. Most users, including those with combination or oily skin, tolerate it without an uptick in blackheads or pimples. Still, its fatty side means a small number of very breakout-prone people might notice congestion, especially if the finished product also contains richer oils. Overall it is considered suitable for acne-prone skin but not completely risk free. Remember the final comedogenic impact always depends on the full formula, how much of the ester is used and how often the product is applied.
Summary
Di-C14-15 Alkyl Tartrate works as a skin conditioner and emollient. It softens surface cells, fills in rough spots and adds a silky glide so creams and serums spread easily yet sink in quickly. By marrying grape derived tartaric acid with plant based fatty alcohols it delivers the sensory feel people like from silicones while keeping a botanical label.
The ingredient sits in the middle of the popularity chart, common enough to show up in moisturizers, primers and masks from natural leaning brands but not as widespread as classic emollients like caprylic/capric triglyceride. Formulators pick it when they want a light non greasy finish without relying on petroleum sources.
Safety studies and real world use point to a low risk of irritation or absorption, making it suitable for most skin types including sensitive or pregnant users. As with any new cosmetic, patch testing a small area first is the smartest way to make sure your skin agrees with it.
