Hydroxyectoin

Hydroxyectoin at a glance

Hydroxyectoin is a crystal powder that dissolves in water. The supplier specification gives a very wide pH range of 1 to 9, and the site lists a typical active level of about 0.1 to 0.5% in leave-on products. Listed uses are appearance-focused cosmetic cosmetics, face lotions, night creams, appearance-focused cosmetic serums, even-tone creams, moisturizing serums and protective creams. Confirm the full INCI name and purity on the supplier CoA.

The extremolyte story

Some microorganisms live in salt lakes, deserts and hot springs. To survive, they produce small molecules called extremolytes that bind water and shield their proteins and membranes. Ectoine is the best known, and hydroxyectoin is its close relative. In skin care, these molecules are used for moisturizing, comforting and protective claims. They suit sensitive skin products because they are gentle and well tolerated.

Product formats

Moisturizing serums

A simple serum with hydroxyectoin and hyaluronic acid makes a strong hydration product.

Night creams

Add it to the water phase of a rich night cream for a comforting overnight story.

Protective day creams

The supplier specification lists protective creams. Pair it with antioxidants for an urban defense story.

Face lotions

Light lotions and toners carry it easily thanks to its water solubility.

Processing

Dissolve the crystals in the water phase at room temperature. The wide pH tolerance makes it easy to combine with acids or with alkaline ingredients. It can be added before or after heating, but adding it at cool-down is the simplest approach.

Good partners

Hyaluronic acid and glycerin complete a hydration base. The Natural Moisturizing Factor liquid fits the same story, and IO Brightening Antioxidant Active Liquid adds an antioxidant angle. Browse more in the actives catalog.

Testing

Measure skin hydration over several hours with a corneometer. A panel can rate comfort and tightness on dry or sensitive skin.

Claims

Skin feels hydrated, comforted and protected from dryness.

Characteristics

Form: crystal powder. Solubility: water soluble. PH range: 1 to 9. Typical active level listed on the site: about 0.1 to 0.5% in leave-on products.

Original recipe: extremolyte hydration serum, 100 g

Distilled water 89.30 g, glycerin 4.00 g, butylene glycol 3.00 g, hydroxyectoin 0.50 g, sodium hyaluronate 0.30 g, panthenol 1.00 g, hydroxyethylcellulose 0.70 g, phenoxyethanol and ethylhexylglycerin 1.00 g, citric acid 0.20 g. Disperse the cellulose in water, dissolve hydroxyectoin and the other ingredients, preserve and adjust the pH.

Pairing with ectoine

Some brands combine ectoine and hydroxyectoin in one product to tell a richer extremolyte story. Both dissolve in water and work across a wide pH range, so they are easy to combine.

Lot records

Keep each CoA with the batch file and note the lot used.

Protective care in daily routines

City air, wind, cold and indoor heating dry the skin. Protective creams aim to help skin feel comfortable through these conditions. Hydroxyectoin suits this category because of its water-binding nature and gentle profile. Combine it with antioxidants and a light lipid phase for a day cream that can be worn under makeup.

Night care

Night creams are another listed format. Overnight, skin loses water through the surface, so a rich cream with humectants and lipids helps it feel smooth in the morning. Hydroxyectoin adds a modern, science-based story to a classic night cream.

Range ideas

A hydration serum, a protective day cream and a comforting night cream can share hydroxyectoin as a common active and a clear extremolyte story.

Storage

Store closed in a dry place. Close the container after use.
