What Is Sodium Myristoyl Hydrolyzed Collagen?
Sodium Myristoyl Hydrolyzed Collagen is a blend of two familiar beauty helpers: collagen and fatty acids. Collagen, the protein that gives skin its bounce, is first broken down into small pieces called peptides so it can dissolve in water. A part of coconut or palm oil called myristic acid is then attached to these peptides, and the whole mix is neutralized with a bit of sodium. The result is a gentle, water-loving powder that quickly mixes into creams, gels and shampoos.
Collagen peptides have been used in skin care since the 1970s, but they used to sit on top of the skin because they were not very compatible with oils. Chemists solved that by linking them with fatty acids in the 1990s. The added myristic acid helps the peptides blend into both water and oil, making the ingredient ideal for modern “all-in-one” formulas.
Today you will spot Sodium Myristoyl Hydrolyzed Collagen in foaming facial cleansers, micellar waters, sulfate-free shampoos, leave-in hair conditioners, sheet masks, lightweight anti-aging lotions, hand creams and even after-shave balms. It is prized for giving formulas a silky feel while supporting soft skin and shiny hair.
Sodium Myristoyl Hydrolyzed Collagen’s Cosmetic Benefits/Uses
This multitasker earns its place on an ingredient list for several reasons:
- Antistatic: Helps reduce static buildup on hair so strands lie smooth and are easier to comb
- Cleansing: Lifts away dirt and oil without stripping skin or hair thanks to its mild foam
- Hair Conditioning: Forms a light film that adds slip, boosts shine and cuts down on breakage during styling
- Skin Conditioning: Leaves a soft, hydrated finish that can make skin feel firmer and more comfortable
Who Can Use Sodium Myristoyl Hydrolyzed Collagen
Sodium Myristoyl Hydrolyzed Collagen generally plays well with most skin and hair types. Its mild cleansing action and lightweight conditioning film make it suitable for oily, combination, normal and even mildly dry or sensitive skin. Extremely dry or eczema-prone complexions might prefer richer barrier-repair ingredients because this collagen derivative is not deeply occlusive.
Because the collagen peptides come from animal sources such as fish or bovine hides, the ingredient is not considered vegan or vegetarian friendly. Shoppers following plant-based lifestyles should look for synthetic or plant-derived alternatives labeled “vegan collagen” instead.
Current research shows no specific safety concerns for pregnant or breastfeeding women when the ingredient is used topically in cosmetic concentrations. Still, this is not medical advice and anyone who is expecting or nursing should review all personal care products with a qualified healthcare provider to be extra cautious.
The molecule does not make skin more sensitive to sunlight, so it is not classed as a photosensitizer. Routine daytime sun protection is still recommended as part of a complete skincare regimen.
Potential Side Effects/Adverse Reactions
Responses to Sodium Myristoyl Hydrolyzed Collagen can differ between individuals. The points below outline possible side effects if the ingredient is applied topically. They remain uncommon when products are formulated and used as directed.
- Allergic reaction – rare cases of hives or swelling due to fish or bovine protein sensitivity
- Mild skin irritation – temporary redness or stinging, more likely on compromised or very reactive skin
- Contact dermatitis – itching or rash from repeated exposure in those with preexisting sensitivities
- Eye irritation – watering or burning if cleansing foam accidentally enters the eyes
- Product buildup on hair – limp or greasy feel when leave-in formulas are overused or not rinsed well
If any adverse reaction occurs stop use immediately and consult a healthcare professional for advice.
Comedogenic Rating
Rating: 1 / 5
Sodium Myristoyl Hydrolyzed Collagen is largely water soluble and forms only a very thin breathable film on skin, so it is unlikely to clog pores. The attached myristic acid segment is small and diluted in finished products, which keeps the overall oiliness low. For these reasons the ingredient sits at the lower end of the scale.
Acne-prone or breakout-prone users can generally tolerate it without issues.
As with any film formers, very heavy layering of multiple products containing this ingredient could raise the risk of pore congestion, but this is uncommon.
Summary
Sodium Myristoyl Hydrolyzed Collagen works as a gentle cleanser, antistatic agent and lightweight conditioner for both skin and hair. Its collagen peptides attract water for softness while the myristic acid tail helps it mix with oils, lifting away grime and smoothing cuticles in one step.
You will most often see it in sulfate-free shampoos and mild facial cleansers, though it also pops up in leave-in sprays and light lotions. It is a niche ingredient rather than a blockbuster, but formulators who focus on mildness and a silky feel appreciate what it brings to the table.
Safety data show it is low irritation and low comedogenic, making it suitable for everyday use on most skin types. Still, everyone’s skin is unique so it is smart to patch test any new product that contains it before full use.
