What Is Dimethicone Peg/Ppg-20/23 Benzoate?
Dimethicone Peg/Ppg-20/23 Benzoate is a silicone based ingredient formed by joining dimethicone with a blend of polyethylene glycol (PEG) and polypropylene glycol (PPG) units, then partially esterifying the result with benzoic acid. The numbers 20 and 23 represent the approximate counts of ethylene oxide and propylene oxide units attached, which influence how well the molecule mixes with both water and oil. This hybrid structure gives the ingredient a lightweight silky feel that silicones are loved for along with the spreadability of certain emulsifiers.
Silicones have been part of cosmetics since the 1950s when formulators discovered their ability to create smooth textures that glide over skin. Over time scientists modified basic dimethicone to add extra benefits such as better solubility and an improved skin finish. Dimethicone Peg/Ppg-20/23 Benzoate is one of those advances, first surfacing in the 1990s as chemists looked for gentle skin conditioners that could also help stabilize modern water in silicone emulsions.
The manufacturing process starts with dimethicone, which is reacted with ethylene oxide and propylene oxide in a controlled setting to graft on the PEG and PPG chains. The resulting copolymer is then partially esterified with benzoic acid. Each step is monitored to keep the final material clear odorless and nonreactive.
Because of its balanced oil and water affinity you will see Dimethicone Peg/Ppg-20/23 Benzoate in a wide range of leave on products. It shows up in lightweight moisturizers, anti aging serums, priming creams, sheet mask essences and even sunscreens where a smooth breathable film is desired. It is also handy in color cosmetics such as foundation and BB creams where it helps pigment glide evenly and stay put.
Dimethicone Peg/Ppg-20/23 Benzoate’s Cosmetic Benefits/Uses
This ingredient carries out one key role in skin care formulas
Skin Conditioning: Dimethicone Peg/Ppg-20/23 Benzoate forms a soft flexible veil on the surface of the skin that helps lock in moisture and leaves a silky non greasy touch. The film fills in tiny surface gaps so skin feels instantly smoother which can visually blur fine lines and rough patches. Its partly water compatible nature allows it to spread easily and rinse off without heavy residue making it suitable for both daily moisturizers and sophisticated makeup products.
Who Can Use Dimethicone Peg/Ppg-20/23 Benzoate
This silicone ester suits most skin types. Dry and normal skin benefit from the light occlusive film that slows water loss while oily or combination skin appreciate its breathable finish that does not feel heavy or greasy. Sensitive skin generally tolerates it well thanks to the ingredient’s inert non reactive nature. The only group that may wish to approach with caution is anyone with a known sensitivity to silicones or PEG derivatives because rare irritation can occur.
Dimethicone Peg/Ppg-20/23 Benzoate is a fully synthetic material with no animal sourced components so it is considered suitable for both vegetarians and vegans. It is also cruelty free as production does not require animal testing in regions that ban the practice.
Current safety data indicates that topical use is acceptable during pregnancy and while breastfeeding. That said this is not medical advice and anyone who is pregnant or nursing should show the full ingredient list of any product to their healthcare provider before using it just to be safe.
The molecule does not absorb UV light or increase the skin’s sensitivity to sunlight so it is not regarded as photosensitising. It can actually improve the wear of sunscreens by helping them spread evenly.
Potential Side Effects/Adverse Reactions
Side effects from topical Dimethicone Peg/Ppg-20/23 Benzoate vary from person to person. The points below cover potential issues though most users will never experience them when the ingredient is formulated and used correctly.
• Mild redness or itching in individuals allergic to silicones or PEGs
• Transient stinging if applied to broken or freshly exfoliated skin
• Very rare clogging of pores in those extremely prone to acne when used in heavy leave on layers
If any discomfort persists stop using the product and consult a doctor or dermatologist.
Comedogenic Rating
Dimethicone Peg/Ppg-20/23 Benzoate rates a 1 on the 0-5 comedogenic scale. Its large silicone backbone sits on top of skin rather than sinking into pores and the added PEG/PPG chains keep the film light and breathable, so it is unlikely to trap oil or debris. For most acne-prone users it is considered low risk, though extremely congested skin may still prefer simpler formulas. Because it has slip and reduces friction it can even help prevent mechanical irritation that sometimes worsens breakouts.
Summary
Dimethicone Peg/Ppg-20/23 Benzoate acts mainly as a skin conditioner. It forms a thin flexible layer that locks in moisture smooths texture and leaves a soft feel while its partial water solubility helps products spread evenly and rinse clean. This dual nature also supports the stability of modern emulsions and improves the glide of pigments in makeup.
The ingredient is moderately popular. It shows up in a variety of lightweight lotions primers and sunscreens, though basic dimethicone still dominates the market because it is cheaper and more familiar to formulators.
Safety data and decades of silicone use suggest this ester is well tolerated for the vast majority of people with only rare irritation in those sensitive to silicones or PEGs. As with any new skincare ingredient it is wise to patch test a product first to make sure your skin agrees with it before applying more broadly.
