What Is Bis-Vinyldimethicone/Ppg-20 Crosspolymer?
Bis-Vinyldimethicone/Ppg-20 Crosspolymer is a silicone based polymer created by linking bis-vinyldimethicone with small chains of Ppg-20. First developed as chemists looked for lightweight alternatives to heavy oils, it entered cosmetic labs in the late 1990s when silicone technology started reshaping skin and hair care. Production involves two main steps: bis-vinyldimethicone is partially connected with methylhydrogen cyclic siloxanes, then these structures are further joined with bis-allyl Ppg-20. The result is a three-dimensional network that feels soft and velvety on skin. You will commonly spot it in face moisturizers, primers, foundations, leave-in hair treatments, anti-aging creams, sunscreens and wash-off masks where formulators want a smooth luxurious finish without greasiness.
Bis-Vinyldimethicone/Ppg-20 Crosspolymer’s Cosmetic Benefits/Uses
This ingredient pulls double duty in a formula
- Emollient: Creates a thin silky layer that fills in tiny skin gaps which helps skin and hair feel softer and look smoother while cutting down on dryness
- Viscosity controlling: Gives products a pleasing thickness so creams feel rich but not heavy, helps suspend pigments or sunscreen filters evenly and keeps the texture stable over time
Who Can Use Bis-Vinyldimethicone/Ppg-20 Crosspolymer
Because this polymer is lightweight, non greasy and largely inert it tends to sit well on every skin type. Dry skin enjoys the soft emollient film while oily or acne prone skin benefits from its breathability and quick dry feel. Even sensitive skin usually tolerates it since it has no active chemical groups that sting or tingle. The only group that may want to keep an eye on it is those extremely prone to congestion, as any film former can in rare cases trap sebum and lead to breakouts when layered with heavy products.
The ingredient is fully synthetic with no animal derived starting materials, so it is suitable for both vegans and vegetarians. Whether the finished product aligns with a cruelty free lifestyle depends on the brand’s animal testing policy rather than the polymer itself.
Current data show no reproductive toxicity or systemic absorption concerns, so products containing Bis-Vinyldimethicone/PPG-20 Crosspolymer are generally viewed as safe for people who are pregnant or breastfeeding. This is not medical advice and anyone who is expecting or nursing should ask a doctor before adding new skincare just to be safe.
The polymer does not increase photosensitivity, so it will not make skin more likely to burn in the sun. Normal daily sun protection habits still apply because ultraviolet rays damage skin in many other ways.
Potential Side Effects/Adverse Reactions
Reactions to topical Bis-Vinyldimethicone/PPG-20 Crosspolymer differ from person to person. The points below outline potential issues yet they are uncommon when the ingredient is used correctly in well-formulated products.
- Mild redness or stinging: can occur on very reactive or compromised skin barriers
- Acne-like breakouts: rare but possible in individuals highly prone to clogged pores if the overall formula is heavy or not cleansed off properly
- Allergic contact dermatitis: extremely rare but possible for anyone with a silicone sensitivity
- Product pilling: may happen when layered with other film formers leading to small flakes on the skin surface
- Hair buildup: with frequent leave-in use hair may feel coated or look dull until clarified
If any irritation or other unwanted effect appears stop using the product and seek advice from a healthcare professional.
Comedogenic Rating
Rating: 1/5. Bis-Vinyldimethicone/PPG-20 Crosspolymer is a large crosslinked silicone that stays mostly on the surface and does not mix with skin’s natural oils, so it rarely blocks pores. Its lightweight mesh allows sebum to move through, keeping the chance of congestion low compared with heavier occlusives.
Suitable for acne-prone or breakout-prone skin in most cases.
Keep in mind that overall formula and cleansing habits matter; pairing it with heavy waxes or skipping proper removal can still lead to build-up.
Summary
Bis-Vinyldimethicone/PPG-20 Crosspolymer works as a silky emollient and viscosity controller. The three-dimensional silicone network smooths skin and hair, fills micro-gaps for a softer feel, lends products a plush texture and helps pigments or sunscreen filters stay evenly dispersed.
It shows up in primers, moisturizers, sunscreens and hair treatments but it is not as famous as dimethicone or cyclopentasiloxane, so you may spot it more in mid to high-end formulas that chase a cushiony finish without added weight.
Current research finds it non-sensitizing, non-photo-reactive and safe for regular use when formulated correctly. As with any new cosmetic, patch test first to make sure your skin agrees with the complete product.
