Ingredient review
Aluminum Capryloyl Hydrolyzed Collagen
INCI: Aluminum Capryloyl Hydrolyzed Collagen
A collagen-based ingredient that helps control shine and smooth skin texture, but its aluminum content raises mild precaution for sensitive skin.
In plain English
This is a modified form of collagen (a protein naturally found in skin) that has been combined with a fatty acid (caprylic acid) and aluminum. In skincare, it forms a thin, invisible film on the skin's surface that helps absorb excess oil and reduce shine. It also makes the skin feel smoother and softer to the touch. Think of it as a gentle mattifying agent that doesn't dry out the skin.
Quick decision guide
Useful, but context matters
Aluminum Capryloyl Hydrolyzed Collagen 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 Aluminum Capryloyl Hydrolyzed Collagen.
- 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 ingredient created by chemically bonding collagen peptides with caprylic acid (a fatty acid from coconut) and aluminum. The result is a powder-like substance that disperses well in water-based formulas.
How it works
When applied to the skin, it spreads into a very thin, flexible film. This film helps trap excess sebum (oil) on the surface, reducing visible shine. The collagen component also provides a slight smoothing effect, temporarily filling in fine lines and pores for a more even appearance.
Pros
Effective oil control
Helps absorb excess sebum and reduce visible shine for several hours, making it ideal for oily skin types.
Smooths skin texture
The collagen film temporarily fills in fine lines and pores, creating a more even canvas for makeup.
Cons and cautions
Aluminum concern
Some users prefer to avoid aluminum in skincare due to potential irritation or personal preference, though the amount used is very low.
Limited research
There are fewer studies on this specific ingredient compared to simpler mattifying agents like silica or zinc PCA.
Best for
- People with oily or combination skin looking to control shine
- Anyone who wants a smoother base for makeup application
Use caution if
- Individuals with known sensitivity or allergy to aluminum compounds
Usage tips
Safety summary
Generally recognized as safe for topical use at typical concentrations. The aluminum is chemically bound and not readily absorbed. However, individuals with known aluminum sensitivity or those who prefer aluminum-free products may wish to avoid it.
Research notes
Limited peer-reviewed studies specifically on this ingredient. Its safety is inferred from similar modified collagen compounds and general aluminum safety data. The CIR has reviewed related ingredients and found them safe for cosmetic use.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. The aluminum content is considered safe at typical use levels by the Cosmetic Ingredient Review (CIR) panel.
- Common uses
- Mattifying primers, Oil-control lotions, Powders
- Environmental note
- Collagen is typically sourced from animal by-products (bovine or marine). The aluminum and caprylic acid are synthetic or plant-derived. No specific environmental concerns are widely reported.
Good to know
- This ingredient is often found in 'pore-minimizing' or 'matte' primers.
- The aluminum is chemically bound and not free, so absorption is minimal.
- It is not the same as aluminum salts used in antiperspirants.
