What Is Ppg-35 Butyl Ether Phosphate?
Ppg-35 Butyl Ether Phosphate is a synthetic ingredient made by attaching about 35 repeating units of propylene glycol to a butyl alcohol core, then adding a phosphate group at the end. This design gives the molecule both water-loving and oil-loving parts, letting it mix easily with a range of cosmetic materials.
The compound was first explored in the late twentieth century when formulators looked for gentler alternatives to traditional sulfates and stronger emulsifiers. Its balanced structure allowed chemists to create cleansers and creams that felt mild on the skin while still removing dirt and oil. Over time it earned a place in many rinse-off and leave-on products.
Commercial production starts with propylene oxide reacting with butyl alcohol in the presence of a catalyst to build the polyoxypropylene chain. The resulting butyl ether is then treated with phosphoric acid to add the phosphate group. Strict purification follows to remove unreacted materials and ensure cosmetic-grade quality.
You will most often see Ppg-35 Butyl Ether Phosphate in facial cleansers, micellar waters, makeup removers, lightweight moisturizers, sunscreens and hair conditioners. Because it boosts the stability of oil-in-water mixtures and creates a soft creamy texture, it is also common in sheet mask essences and soothing gels.
Ppg-35 Butyl Ether Phosphate’s Cosmetic Benefits/Uses
This multitasking ingredient improves both the feel and performance of many personal care formulas.
- Cleansing: Its amphiphilic nature surrounds and lifts away excess oil makeup and daily grime allowing them to rinse off without stripping the skin
- Emulsifying: It helps blend water with oils silicones and fragrances creating a stable uniform mixture that stays smooth over time and feels pleasant when applied
Who Can Use Ppg-35 Butyl Ether Phosphate
Ppg-35 Butyl Ether Phosphate is generally well tolerated by all major skin types. Its mild cleansing action makes it a good match for oily and combination skin while its low potential for stripping natural moisture keeps it comfortable for normal and even mildly dry skin. Most sensitive skin users report no issues, though anyone with a known sensitivity to polyols or phosphates should proceed with caution.
The ingredient is produced from petroleum-derived feedstocks, not animal sources, making it suitable for both vegetarians and vegans. Manufacturing processes do not typically involve animal by-products, but cruelty-free status depends on the finished brand’s policies.
Available safety data show no reproductive toxicity, so topical use during pregnancy or breastfeeding is not expected to pose a risk. This is not medical advice; anyone who is pregnant or nursing should run their skincare routine past a qualified healthcare provider to be safe.
Ppg-35 Butyl Ether Phosphate does not increase photosensitivity, so it will not make skin more prone to sunburn. It is also compatible with common actives such as niacinamide, vitamin C and retinoids, so formulators can build multi-benefit products without concern for instability.
Potential Side Effects/Adverse Reactions
Side effects from topical use of Ppg-35 Butyl Ether Phosphate differ from person to person. The points below outline potential reactions, but most users experience none of these when the ingredient is used correctly in a well-formulated product.
- Mild redness or stinging on very sensitive skin
- Contact dermatitis in individuals allergic to phosphates or propylene glycol derivatives
- Eye irritation if the product accidentally gets into the eyes
- Temporary dryness or tightness when used in high-foaming cleansers on already dry skin
- Occasional scalp itching when included in shampoos for those with reactive scalps
If any of these reactions occur discontinue use and consult a healthcare professional or dermatologist for guidance.
Comedogenic Rating
Rating: 1/5 – Ppg-35 Butyl Ether Phosphate is highly water soluble and rinses away cleanly, so it does not linger in pores or leave an occlusive film that could trap oil and debris. Its primary role as a cleanser and emulsifier means it helps remove potential pore-clogging substances rather than adding to them. This makes it a low-risk choice for people who are prone to acne or breakouts. Formulas that pair it with heavy oils or waxes could still cause congestion, but the ingredient itself is unlikely to be the culprit.
Summary
Ppg-35 Butyl Ether Phosphate works mainly as a mild cleanser and an emulsifier. Its split personality molecule loves both water and oil which lets it lift grime from the skin and keep creams and lotions evenly blended. Because it balances cleansing power with gentleness it has found a solid place in face washes micellar waters and light moisturizers though it is not as famous as ingredients like glycerin or hyaluronic acid.
Current safety data show it to be non-sensitizing non-phototoxic and suitable for most users including those who are pregnant or vegan. As with any new skincare ingredient do a simple patch test when trying a product that contains it just to be extra careful.
