Ingredient review
Sodium Butylglucosides Hydroxypropyl Phosphate
INCI: Sodium Butylglucosides Hydroxypropyl Phosphate
A mild, biodegradable surfactant that cleanses effectively without stripping the skin barrier — great for sensitive skin.
In plain English
This ingredient is a gentle cleansing agent made from plant sugars and phosphate. It helps lift dirt and oil from your skin so they can be rinsed away, but it's much less harsh than traditional sulfates. Think of it as a soft, effective soap that doesn't leave your face feeling tight or dry.

Quick decision guide
Useful, but context matters
Sodium Butylglucosides Hydroxypropyl Phosphate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Sodium Butylglucosides Hydroxypropyl Phosphate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic surfactant created by chemically modifying glucose (from corn or wheat) with phosphate groups. It belongs to a newer class of mild, eco-friendly cleansing agents often used in 'sulfate-free' formulas.
How it works
It reduces the surface tension between water and oil, allowing impurities to be emulsified and washed away. Its large molecular structure makes it too big to penetrate deeply into the skin, so it stays on the surface and cleans without disrupting the skin's natural moisture barrier.
Pros
Ultra-gentle on skin
Its large molecular size means it cleans without penetrating or stripping the skin barrier, making it ideal for sensitive or compromised skin.
Eco-friendly profile
Derived from renewable plant sources and readily biodegradable, it has a lower environmental impact compared to many petroleum-based surfactants.
Cons and cautions
Low foam volume
It produces a modest, creamy lather rather than big bubbles. Users who equate foam with cleansing power may feel it's not working as well, even though it is.
Potential for slight residue
In some formulations, especially at higher concentrations, it can leave a faint film on the skin or hair, which may not be preferred by those with oily skin.
Best for
- People with dry, sensitive, or eczema-prone skin
- Anyone looking for a sulfate-free, gentle daily cleanser
Use caution if
- Those who prefer a rich, foamy lather may find this too low-foaming
Usage tips
Safety summary
Sodium Butylglucosides Hydroxypropyl Phosphate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
Research on this specific ingredient is limited, but it belongs to a well-studied class of alkyl glucoside surfactants known for their mildness and biodegradability. Studies on similar glucoside surfactants show they are gentle on the skin barrier and have low aquatic toxicity.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions or safety warnings have been issued by the Cosmetic Ingredient Review (CIR) or the European Chemicals Agency (ECHA).
- Common uses
- Cleansers, Facial washes, Shampoos, Body washes, Micellar waters
- Environmental note
- Made from renewable plant sugars and phosphate, it is biodegradable and generally considered more environmentally friendly than traditional sulfate surfactants. However, the phosphate component may contribute to eutrophication in aquatic systems if not properly treated in wastewater.
Good to know
- It is often listed as 'Sodium Butylglucosides Hydroxypropyl Phosphate' on labels — a mouthful, but it's just a gentle cleanser.
- This ingredient is considered 'sulfate-free' and is a common choice in natural and sensitive-skin product lines.
