Hydrolyzed Erythrina Edulis Seed

INCI: Hydrolyzed Erythrina Edulis Seed

A gentle plant protein that helps hydrate and temporarily smooth the skin's surface, though research on its specific benefits is still limited.

In plain English

Hydrolyzed Erythrina Edulis Seed is a protein derived from the seeds of the basul tree, a plant native to South America. In skincare, it is broken down into smaller pieces (hydrolyzed) so it can better interact with the skin. It acts like a gentle sponge, attracting moisture to the skin's surface, and also leaves a light, invisible film that can make the skin feel smoother and temporarily reduce the look of fine lines. Think of it as a natural, plant-based alternative to ingredients like hydrolyzed collagen or wheat protein.

Quick decision guide

Useful, but context matters

Hydrolyzed Erythrina Edulis Seed 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 Erythrina Edulis Seed.
  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 extract from the seeds of the Erythrina edulis tree, also known as the basul or sachaporoto tree. The seeds are rich in amino acids and proteins, which are processed to create a water-soluble ingredient for cosmetics.

How it works

When applied to the skin, the hydrolyzed protein forms a thin, flexible film that helps hold moisture against the skin (a humectant effect). This film also temporarily fills in uneven texture and fine lines, giving a smoothing effect. The amino acids in the ingredient may also support the skin's natural moisture barrier by providing building blocks for natural moisturizing factors.

Pros

Gentle hydration

Attracts moisture to the skin's surface without the stickiness of some heavier humectants, making it suitable for sensitive or dry skin types.

Temporary smoothing

The film-forming action can help blur fine lines and uneven texture, giving a smoother canvas for makeup or a more refined look.

Cons and cautions

Limited research

Most evidence for this ingredient comes from its general protein chemistry, not from large human studies. Its specific anti-aging or barrier-repair claims are not yet well-supported.

Temporary effect

The smoothing and hydrating benefits are surface-level and wash off with cleansing. It does not permanently change the skin's structure or hydration levels.

Best for

  • People looking for a gentle, plant-based hydrating ingredient
  • Those who want a temporary smoothing effect for makeup prep or daytime wear

Use caution if

  • Individuals with a known allergy to legumes (Erythrina is in the Fabaceae family) should patch test first

Usage tips

Apply to slightly damp skin to enhance the humectant effect of the protein.
Use in a serum or moisturizer step before sunscreen or makeup for a smoother base.
If you experience tackiness, try using a smaller amount or layering a lightweight moisturizer over it.

Safety summary

Hydrolyzed Erythrina Edulis Seed is considered safe for topical use with a low risk of irritation or clogging pores. As with any new ingredient, a patch test is recommended for those with legume allergies.

Research notes

Research on this specific ingredient is limited. Its function is inferred from general knowledge of hydrolyzed plant proteins, which are known to be humectant and film-forming. No major clinical trials on Erythrina edulis seed protein in skincare were found in peer-reviewed literature.

Common label clues

Typical concentration
0.5% to 5% in leave-on products
Regulatory status
Generally considered safe for use in cosmetics at typical concentrations. Not restricted by major regulators like the FDA or EU CosIng.
Common uses
Moisturizers, Serums, Anti-aging creams, Eye creams
Environmental note
Sourced from a renewable plant source. The hydrolysis process is typically enzymatic or chemical, but overall environmental impact is considered low compared to synthetic film-formers.

Good to know

  • Erythrina edulis seeds are also a traditional food source in parts of South America, making this ingredient a byproduct of food production.
  • Hydrolyzed proteins are common in hair care too, but this ingredient is primarily used in facial skincare.
