Ingredient review
Sodium C12-14 Sec-Pareth-3 Sulfate
INCI: SODIUM C12-14 SEC-PARETH-3 SULFATE
A gentle sulfate-based cleanser that effectively removes dirt and oil without stripping the skin.
In plain English
This is a mild cleansing ingredient, similar to sodium lauryl sulfate but designed to be less harsh. It helps create a foamy lather in products like face washes and shampoos, lifting away dirt, oil, and makeup. Because it's a secondary alcohol ethoxylate sulfate, it tends to be gentler on skin than many traditional sulfates.

Quick decision guide
Useful, but context matters
Sodium C12-14 Sec-Pareth-3 Sulfate 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 C12-14 Sec-Pareth-3 Sulfate.
- 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 synthetic anionic surfactant derived from secondary alcohols, ethoxylated and sulfated. It belongs to the sulfate family but is modified to reduce irritation.
How it works
It works by reducing the surface tension between water and oil, allowing water to mix with and rinse away oily dirt and sebum. Its molecular structure forms micelles that trap impurities, which are then washed off.
Pros
Gentler than traditional sulfates
Its secondary alcohol structure makes it less irritating than sodium lauryl sulfate, so it's a better choice for daily use on normal skin.
Effective foaming and cleansing
Creates a satisfying lather that helps users feel clean, while still being mild enough for many skin types.
Cons and cautions
Potential for dryness
Even though it's milder, frequent use can still strip natural oils from very dry or sensitive skin, leading to tightness or irritation.
Synthetic origin
As a lab-created ingredient, it may not be suitable for those seeking exclusively natural or plant-based formulations.
Best for
- People with normal to oily skin looking for a gentle foaming cleanser
- Those who want effective cleansing without excessive irritation
Use caution if
- Individuals with extremely dry, compromised, or eczema-prone skin may prefer non-sulfate alternatives
Usage tips
Safety summary
Considered safe for use in rinse-off cosmetics at typical concentrations. Low irritation potential compared to harsher sulfates, but may still cause dryness in sensitive individuals with overuse.
Research notes
Limited peer-reviewed studies specifically on this ingredient, but it is structurally similar to other secondary alcohol ethoxylate sulfates which have been evaluated as mild surfactants. Safety assessments by cosmetic ingredient review panels support its use.
Common label clues
- Typical concentration
- Typically 5–15% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general surfactant safety limits.
- Common uses
- Facial cleansers, Body washes, Shampoos, Shower gels
- Environmental note
- Biodegradable under standard conditions, but as a synthetic surfactant, its production involves petrochemical derivatives.
Good to know
- This ingredient is often found in 'gentle' or 'mild' cleanser formulas as a compromise between strong sulfates and non-foaming cleansers.
- It is biodegradable and generally considered safe for the environment at typical use levels.
