What Is Peg-35 Almond Glycerides?
Peg-35 Almond Glycerides is a plant derived ingredient made by combining the natural fats found in sweet almond oil with ethylene oxide. The reaction attaches an average of 35 ethoxy units to the mono- and diglycerides that occur in almond oil, creating a substance that mixes well with both water and oil. First explored in the 1970s when formulators were looking for milder, more sustainable emulsifiers, it has since gained steady popularity thanks to its gentle feel and versatility.
The manufacturing process starts with pressing almonds to obtain oil, then splitting that oil into mono- and diglycerides. These molecules are treated with controlled amounts of ethylene oxide to achieve the desired level of ethoxylation. The result is a creamy liquid or soft paste that disperses easily in water-based systems yet still loves oil, making it ideal for modern skin care.
You will most often see Peg-35 Almond Glycerides in lightweight facial moisturizers, hydrating serums, cleansing milks, makeup removers, sheet mask essences, sunscreen lotions and even some hair conditioners. Its plant origin and skin friendly profile make it a favorite in products aimed at sensitive or dry skin.
Peg-35 Almond Glycerides’s Cosmetic Benefits/Uses
This ingredient serves as an emulsifying agent, meaning it helps water and oil stay blended in a stable, uniform mixture. By keeping a formula from separating it ensures that every pump or scoop delivers the same ratio of actives, oils and humectants to the skin. A stable emulsion spreads more smoothly, feels silkier and improves the overall sensory experience of a cream or lotion.
Who Can Use Peg-35 Almond Glycerides
This emulsifier is considered gentle enough for most skin types including dry, normal, combination and even sensitive skin because it does not leave a heavy residue or disrupt the skin barrier. Oily or acne prone users usually tolerate it well since the ingredient itself is lightweight and non greasy.
Peg-35 Almond Glycerides is produced from plant sourced almond oil with no animal derived components so it is suitable for both vegetarians and vegans.
Current safety data shows no specific risks for women who are pregnant or breastfeeding when the ingredient is used as part of a rinse off or leave on cosmetic formula, but this is not medical advice and anyone expecting or nursing should review any skincare product with their doctor to be sure it fits their personal needs.
The ingredient does not make skin more sensitive to sunlight and there are no known interactions with common actives such as retinoids or vitamin C.
Potential Side Effects/Adverse Reactions
Responses to topical Peg-35 Almond Glycerides can vary from one individual to another. The effects listed below are possible yet unlikely when the ingredient is properly formulated within a finished product.
- Mild transient redness or stinging in very sensitive skin
- Allergic response in individuals with severe tree nut allergies
- Contact dermatitis triggered by traces of ethoxylation by products in extremely reactive users
- Tearing or eye irritation if the product accidentally enters the eyes
Discontinue use and consult a healthcare professional if any of these reactions occur.
Comedogenic Rating
Rating: 1 / 5
Peg-35 Almond Glycerides scores a low 1 because the ethoxylation process makes the almond-derived fats highly water dispersible, so they do not sit on the skin in a thick occlusive layer that might clog pores. The molecule is also used at modest percentages, further reducing any build-up risk. Still, it does contain a nut-based lipid backbone, so individuals with extremely oily skin may want to see how their skin responds.
Suitable for acne-prone users in most cases
No specific interactions are known with common acne treatments and it can even help formulas rinse away cleanly, which may indirectly support clearer skin.
Summary
Peg-35 Almond Glycerides is primarily an emulsifier, helping water and oil blend smoothly so a lotion or cream stays uniform from the first to the last use. Its partly water-loving structure gives products a light, silky spread without greasy afterfeel, improving both performance and user experience.
While not as widely talked about as shea butter or hyaluronic acid, this plant-based emulsifier has carved out a quiet niche in gentle cleansers, moisturizers and sunscreens where a mild touch is valued. Formulators appreciate its balance of natural origin and reliable lab performance.
Current safety reviews place it in the low-risk category for topical use with minimal irritation potential. As with any new skincare product, it is wise to carry out a small patch test first to confirm personal compatibility.
