What Is Dilauroyl Trimethylolpropane Siloxy Silicate?
Dilauroyl Trimethylolpropane Siloxy Silicate is a hybrid molecule that combines fatty acid esters with a silicate backbone. Chemically it links two lauric acid chains to a trimethylolpropane core, which is then bonded to siloxy silicate segments. The lauric acid portion comes from coconut or palm kernel oil while the silicate portion is derived from silica sand.
The ingredient emerged in the early 2000s when formulators looked for lightweight alternatives to heavy plant butters. By grafting softening fatty chains onto a rigid silicate cage they created a material that feels silky yet non greasy. Its introduction coincided with the rise of long-wear makeup and transfer resistant skin care where flexible film formers were needed.
Manufacturing starts with transesterifying lauric acid with trimethylolpropane to produce dilauroyl trimethylolpropane. This intermediate is then reacted with chlorosilanes followed by controlled hydrolysis to build the silicate network. The end product is a fine powder or viscous resin that disperses easily in oils and silicones.
You will most often see Dilauroyl Trimethylolpropane Siloxy Silicate in primers, long lasting foundations, facial creams aimed at barrier repair, tinted moisturizers and certain sheet mask essences. Its ability to form a breathable yet water resistant layer makes it useful in anti pollution formulas and SPF products as well.
Dilauroyl Trimethylolpropane Siloxy Silicate’s Cosmetic Benefits/Uses
This multifunctional compound primarily serves one role in skin care products.
Skin conditioning: By combining fatty laurate tails with a silicate framework the ingredient spreads smoothly over skin creating a micro film that locks in moisture, softens rough patches and gives a satin finish. It supports the skin barrier without leaving a heavy residue so formulas feel comfortable for hours even in humid or dry environments.
Who Can Use Dilauroyl Trimethylolpropane Siloxy Silicate
This silky film former suits most skin types. Normal, dry and combination skins appreciate its moisture-locking feel while oily or acne-prone complexions benefit from its light texture that does not add surface grease. Sensitive skin generally tolerates it well since it is non-fragrant and chemically stable, though anyone with a history of silicone allergies should exercise caution.
The lauric acid portion now comes almost exclusively from coconut or palm kernel oil so the ingredient is plant derived. No animal-sourced components are required which makes it acceptable for vegetarians and vegans, provided the finished product has not been tested on animals according to personal ethics or regional regulations.
Current safety data show no indication that Dilauroyl Trimethylolpropane Siloxy Silicate is absorbed in significant amounts through intact skin. Products containing it are therefore considered low risk for women who are pregnant or breastfeeding. This is not medical advice and expectant or nursing mothers should still clear any new skincare with their physician to be safe.
The molecule is not known to cause photosensitivity and has no documented interaction with UV light. It can comfortably be used during the daytime alongside sunscreen.
Potential Side Effects/Adverse Reactions
Responses to topical Dilauroyl Trimethylolpropane Siloxy Silicate differ from person to person. The points below outline potential side effects but they remain uncommon when the ingredient is used at customary levels in well-formulated products.
- Mild skin irritation – transient redness or stinging can occur, usually in those with pre-existing sensitivity to silicones or fatty acids
- Contact dermatitis – rare allergic reactions may present as itching, rash or swelling
- Acne flare-ups – although low in pore-clogging potential a small minority with highly reactive acne may notice breakouts
- Eye discomfort – if a product accidentally gets into the eyes it may cause watering or a gritty feeling until rinsed out
Discontinue use and consult a qualified healthcare professional if any persistent or severe reaction develops.
Comedogenic Rating
Rating: 1/5
Dilauroyl Trimethylolpropane Siloxy Silicate sits mostly on the skin without melting into pores, and its large hybrid molecule is bulky enough to stay on the surface. The lauric tails are bound within a silicate cage which limits the free lauric acid that could clog pores. In real-world formulas it is used at low levels, further lowering the risk.
Suitable for acne-prone or breakout-prone skin, though individual reactions can vary.
If a product contains heavy oils alongside this ingredient overall pore-clogging potential may rise, so always look at the full formula.
Summary
Dilauroyl Trimethylolpropane Siloxy Silicate conditions skin by forming a soft breathable film that smooths texture, locks in water and gives a velvety finish without grease. It does this by combining flexible fatty chains with a sturdy silicate network that spreads evenly and resists wash-off.
The ingredient shows up most often in long-wear makeup, primers and barrier creams but it is still a niche additive compared with classic silicones or plant oils. Brands that focus on lightweight feel and transfer resistance are helping it gain traction.
Current safety reviews classify it as low risk for irritation, sensitization or systemic absorption. As with any new cosmetic it is wise to patch test first to check personal tolerance.
