Ingredient review

Hydrolyzed Maple Sycamore Protein

INCI: Hydrolyzed Maple Sycamore Protein

A gentle, plant-based protein that may help strengthen hair and temporarily smooth skin, but research is limited compared to more established proteins like keratin or collagen.

In plain English

This ingredient is a protein taken from the seeds of the maple sycamore tree. It's been broken down into smaller pieces (hydrolyzed) so it can more easily stick to hair or skin. On hair, it forms a thin film that can make strands feel thicker and stronger, and it may help repair damage from heat or styling. On skin, it can provide a temporary smoothing effect by filling in rough spots. Think of it like a plant-based alternative to animal-derived proteins, though it hasn't been studied as much.

Quick decision guide

Useful, but context matters

Hydrolyzed Maple Sycamore Protein 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Hydrolyzed Maple Sycamore Protein.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

A hydrolyzed (broken down) protein extracted from the seeds of the maple sycamore tree (Acer pseudoplatanus). The hydrolysis process creates smaller peptide chains that can penetrate the hair shaft or adhere to the skin's surface.

How it works

When applied to hair, the small protein fragments bind to the hair cuticle, filling in gaps and forming a protective film. This can temporarily strengthen the hair, reduce breakage, and add body. On skin, the protein forms a thin, flexible layer that helps retain moisture and smooth the skin's texture by temporarily filling fine lines or rough patches.

Pros

Plant-based and sustainable

Derived from maple sycamore seeds, this protein offers a vegan-friendly alternative to animal-derived proteins like keratin or collagen, appealing to eco-conscious consumers.

Gentle on hair and skin

With low irritation and comedogenic risk, it's suitable for most skin types, including sensitive skin, and can be used in daily products without causing buildup or breakouts.

Cons and cautions

Limited research backing

Compared to well-studied proteins like hydrolyzed wheat or keratin, there is less published evidence specifically supporting the benefits of maple sycamore protein, so results may vary.

Temporary effects

The strengthening and smoothing benefits are not permanent; they wash away with shampoo or cleanser, requiring consistent use to maintain results.

Best for

  • People with fine or damaged hair looking for temporary strengthening
  • Those seeking plant-based protein alternatives in their hair or skin care

Use caution if

  • Individuals with known allergies to maple tree pollen or seeds should patch test first

Usage tips

Look for this ingredient in leave-in conditioners or hair masks for longer contact time and better adhesion to hair.
Pair with other moisturizing ingredients like glycerin or aloe vera to prevent dryness from protein-heavy formulas.

Safety summary

Hydrolyzed maple sycamore protein is considered safe for topical use in cosmetics. It has a low potential for irritation and is not known to be comedogenic. As with any new ingredient, a patch test is recommended for those with plant allergies.

Research notes

While plant proteins in general are well-documented for hair and skin benefits, specific peer-reviewed studies on hydrolyzed maple sycamore protein are scarce. Most evidence comes from manufacturer data and broader research on hydrolyzed plant proteins.

Common label clues

Typical concentration
0.1% to 2% in rinse-off products; up to 1% in leave-on products
Regulatory status
Generally recognized as safe for cosmetic use in the US and EU; no specific restrictions beyond standard cosmetic ingredient regulations.
Common uses
Shampoos, Conditioners, Hair masks, Leave-in treatments, Facial serums, Moisturizers
Environmental note
Maple sycamore trees are widely cultivated and the seeds are a byproduct, making this a relatively sustainable ingredient when sourced responsibly.

Good to know

  • Hydrolyzed proteins are often listed near the end of ingredient lists because they are effective at low concentrations.
  • This protein is sometimes used in combination with other plant proteins to create a more complete amino acid profile.
