Ingredient review
Diglycereth-7 Malate
INCI: DIGLYCERETH-7 MALATE
A lightweight, water-loving emollient that hydrates and softens skin without clogging pores or feeling heavy.
In plain English
Diglycereth-7 Malate is a semi-synthetic ingredient made by combining glycerin, a natural moisturizer, with malic acid (found in apples) and a small amount of fatty material. The result is a clear, water-soluble liquid that spreads easily on the skin, leaving it feeling smooth and hydrated without any greasy residue. It works like a gentle moisturizer that also helps other ingredients absorb better.

Quick decision guide
Useful, but context matters
Diglycereth-7 Malate 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 Diglycereth-7 Malate.
- 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 compound created by esterifying glycereth-7 (a glycerin derivative) with malic acid. It is a clear, water-soluble liquid that acts as both an emollient (softening agent) and a humectant (water-attracting agent).
How it works
Diglycereth-7 Malate sits on the skin's surface, forming a thin, non-occlusive film that helps lock in moisture while also attracting water from the air. Its malate portion may gently exfoliate the outermost layer of dead skin cells, promoting a smoother texture. Additionally, it can improve the spreadability of other ingredients in a formula.
Pros
Lightweight hydration
Unlike heavier oils, Diglycereth-7 Malate provides moisture without leaving a sticky or greasy film, making it ideal for daytime use and oily skin types.
Gentle on skin
With low irritation and comedogenic risk, it is suitable for sensitive and acne-prone skin, unlikely to cause breakouts or redness.
Cons and cautions
Modest evidence base
While safe and effective in formulations, there are fewer peer-reviewed studies on Diglycereth-7 Malate compared to classic humectants like glycerin, so its long-term benefits are less documented.
Dependent on formulation
Its performance can vary widely depending on the product's overall formula; in low concentrations or poor formulations, its hydrating effect may be minimal.
Best for
- People with normal to oily skin who want hydration without heaviness
- Anyone looking for a gentle, non-irritating moisturizing ingredient
Use caution if
- Those with known sensitivities to malic acid or glycerin derivatives (rare)
Usage tips
Safety summary
Diglycereth-7 Malate is considered safe for cosmetic use with low irritation and comedogenic potential. It is well-tolerated by most skin types, including sensitive skin. No significant safety concerns have been reported in the available literature.
Research notes
Research on Diglycereth-7 Malate is limited but consistent with its chemical relatives. Studies on similar glycereth esters and malate compounds support its role as a safe, effective humectant and emollient. More independent research would strengthen the evidence base.
