Palmitamide DEA

INCI: Palmitamide DEA

Palmitamide DEA helps create rich lather and thicken cleansers, but may cause irritation for sensitive skin and has moderate comedogenic potential.

In plain English

Palmitamide DEA is a synthetic ingredient added to cleansers and shampoos to make them foam more richly and feel thicker. It's a type of amide made from palmitic acid (a fatty acid) and diethanolamine. While it improves the sensory experience of a product, it can be drying or irritating for some people, especially those with sensitive or acne-prone skin. It also has a moderate chance of clogging pores.

Quick decision guide

Useful, but context matters

Palmitamide DEA can be useful, but watch for some irritation potential and possible clogging concerns.

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 Palmitamide DEA.
  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

moderate

Can bother some users, especially with frequent use, damaged skin, or strong companion ingredients.

Clogging risk

moderate

May be fine for many users but deserves caution if you are breakout-prone.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

Palmitamide DEA is a synthetic surfactant and foam booster derived from palmitic acid (a saturated fatty acid found in palm oil) and diethanolamine (DEA). It is used primarily to enhance lather and increase the viscosity of cleansing products.

How it works

In a cosmetic product, Palmitamide DEA works by stabilizing foam bubbles and increasing the thickness of the liquid formula. It interacts with other surfactants to create a denser, creamier lather that feels luxurious on the skin or hair. It also helps suspend other ingredients in the formula.

Pros

Rich lather

Creates a dense, creamy foam that many people find satisfying in shampoos and body washes.

Thickens formulas

Helps achieve a luxurious, gel-like texture without needing high concentrations of primary surfactants.

Cons and cautions

May irritate sensitive skin

Can cause stinging, redness, or dryness for those with compromised skin barriers or conditions like eczema.

Moderate pore-clogging risk

Rated moderately comedogenic, meaning it may contribute to breakouts for acne-prone individuals.

Best for

  • People who enjoy rich, creamy lather in cleansers
  • Those with normal to oily skin not prone to irritation

Use caution if

  • Individuals with sensitive, reactive, or eczema-prone skin
  • Those with acne-prone skin concerned about pore clogging

Usage tips

If you have sensitive skin, patch test a new product containing Palmitamide DEA on your inner arm before using it on your face.
Follow with a gentle, hydrating moisturizer to offset any potential drying effects from this ingredient.
Consider alternating with sulfate-free cleansers if you notice irritation or dryness.

Safety summary

Palmitamide DEA is generally recognized as safe in rinse-off products at typical use levels. However, it carries a moderate risk of skin irritation and comedogenicity, so it is not ideal for sensitive or acne-prone skin. Regulatory bodies consider it acceptable when properly formulated.

Research notes

Studies indicate that Palmitamide DEA can cause mild to moderate skin irritation in some individuals, especially at higher concentrations. The Cosmetic Ingredient Review (CIR) panel concluded it is safe for use in cosmetics when formulated to avoid irritation. No significant systemic toxicity has been reported from topical use.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics in the US (FDA) and EU (CosIng) at concentrations up to 5%. The Cosmetic Ingredient Review (CIR) panel has deemed it safe when formulated to be non-irritating.
Common uses
Shampoos, Body washes, Facial cleansers, Liquid soaps
Environmental note
DEA compounds can be persistent in aquatic environments. Some manufacturers are moving toward more biodegradable alternatives due to environmental concerns.

Good to know

  • Palmitamide DEA belongs to a class of ingredients called alkanolamides, which are common in personal care products.
  • Some DEA compounds have raised environmental and health concerns, though Palmitamide DEA is considered safe at typical cosmetic concentrations by major regulatory bodies.
  • It is often used alongside stronger surfactants like sodium lauryl sulfate to moderate their harshness.
