What Is Platinum Divinyldisiloxane?
Platinum Divinyldisiloxane is a specialty silicone complex created by reacting chloroplatinic acid with divinyldisiloxane, leaving tiny amounts of platinum anchored within a vinyl-rich silicone backbone. Originally explored in the 1990s for high-tech coatings, formulators soon noticed that the smooth flexible film it forms could benefit skin care textures. Today the ingredient is produced in controlled lab settings where chloroplatinic acid and divinyldisiloxane are blended under precise temperature and pH, then purified to remove unwanted by-products. The end material is a clear fluid that disperses easily into oils, silicones or emulsions.
You will most often find Platinum Divinyldisiloxane in leave-on products that aim for a refined finish such as primers, anti-aging serums, overnight masks, lightweight moisturizers and high-performance foundations. Its film forming nature also makes it useful in long-wear eye or lip treatments where a flexible layer is needed.
Platinum Divinyldisiloxane’s Cosmetic Benefits/Uses
This ingredient adds both functional and sensory advantages to modern formulas.
- Film Forming – Creates a thin breathable layer on the skin that locks in moisture, improves spreadability and helps pigments or active ingredients stay in place longer
- Skin Conditioning – Leaves skin feeling soft and silky, reduces rough texture and can enhance the appearance of smoothness for a more even-toned look
Who Can Use Platinum Divinyldisiloxane
Because it forms a weightless breathable film, Platinum Divinyldisiloxane tends to suit most skin types including dry, normal, combination and oily. Those with very sensitive or highly reactive skin usually tolerate it well since the molecule is non-reactive and fragrance free, but anyone prone to silicone sensitivities may want to proceed with caution.
The ingredient is produced entirely from mineral sourced platinum and laboratory made silicones with no animal derivatives, so it is generally considered suitable for vegans and vegetarians. Brands that certify their finished products as vegan will often include it without issue.
Current research shows no evidence that topical Platinum Divinyldisiloxane penetrates deeply or interferes with hormones, so it is not known to pose a specific risk to women who are pregnant or breastfeeding. That said, this is not medical advice and anyone expecting or nursing should review all skincare products with a qualified healthcare provider to be extra safe.
Platinum Divinyldisiloxane does not make skin more sensitive to sunlight and can be worn day or night. It also plays nicely with common actives like retinol, vitamin C and niacinamide, making it a flexible option in multi-step routines.
Potential Side Effects/Adverse Reactions
Responses to any cosmetic ingredient vary from person to person. The issues listed below are possible outcomes but most users will not experience them when the product is formulated and used as intended.
- Mild transient redness or itching especially on very sensitive skin
- Rare allergic contact dermatitis presenting as persistent rash or swelling
- Breakouts or clogged pores in individuals who react poorly to certain silicones
- Occlusive feel in heavy formulations which may be uncomfortable for those who prefer an ultra-light texture
If any unwanted reaction develops stop using the product and seek advice from a dermatologist or healthcare professional.
Comedogenic Rating
Rating: 1 / 5
Platinum Divinyldisiloxane sits on the surface as a breathable film rather than sinking into pores, and the molecule is too large to block follicular openings under normal use. Most silicones share this low clogging profile, which is why the rating is close to non-comedogenic but not a perfect zero, since individual skin chemistry can differ. In lightweight formulas the risk of acne flare-ups is minimal, though very occlusive or layered routines could raise the chance slightly for highly congestion-prone users.
Bottom line: generally suitable for acne-prone skin but monitor how your own skin responds.
Summary
Platinum Divinyldisiloxane is valued for two key jobs: it forms a thin flexible film that locks in moisture and anchors pigments or actives, and it conditions skin for a soft silky after-feel. It achieves both by linking vinyl-rich silicone chains with tiny traces of platinum, creating a stable network that stays put yet allows skin to breathe.
While not as widespread as household names like dimethicone, it is gaining traction in premium primers, long-wear makeup and night treatments where a refined finish is prized.
Current data shows it is safe for topical use with very low irritation or sensitization rates. As with any new skincare ingredient performing a simple patch test before full-face application is a smart step to make sure your skin stays happy.
