Hyaluronic Acid, Vegetable, LMW, 10 - 50 kDa 1g

Hyaluronic acid with low molecular weight 10 – 50 kDa is a moisturising active ingredient for the water phase of serums, tonics and light emulsions. According to the manufacturer, short chains penetrate deeper into the skin than high-molecular types, which is why this fraction is chosen where hydration is intended to act below the skin surface. The raw material is produced by fermentation of carbohydrates using an unmodified bacterial strain, without raw materials of animal origin, and is approved for natural cosmetics COSMOS and NATRUE.

The powder dissolves in water and at a dosage of 0.05 – 0.5% only slightly increases viscosity. Serums and tonics thus retain a fluid texture.

What it brings to the formulation

• Deep hydration – the molecule binds a large amount of water. For short chains of 10 – 50 kDa, the manufacturer states high penetration ability into the skin, so the moisturising effect reaches deeper layers as well.
• Smoothing of fine lines – according to the manufacturer, with regular use it can reduce the visibility of fine wrinkles and lines. The result depends on the full formulation and dosage.
• Nourishment of the skin – for this fraction, the manufacturer states a nourishing effect in addition to hydration, making it suitable for regenerating and anti-wrinkle products.
• Minimal impact on viscosity – thickens considerably less than high-molecular types. Suitable for tonics, mists and essences where a light, watery consistency is desired.
• Natural origin and vegan character – biotechnological production without animal-derived raw materials, without palm oil components and without GMO.

Use in formulation

Added to the water phase. The powder is slowly poured into water with intensive stirring until completely dissolved.

The recommended dosage is 0.05 – 0.5%. At a concentration of 0.2 – 0.5% in water, the manufacturer states that a clear, slightly gel-like solution forms; at lower doses, it remains fluid. The finished product should have a pH in the range of 5 – 8.

The manufacturer offers hyaluronic acid in several molecular weights. The longer the chain, the more water the molecule binds and the more it thickens, but at the same time it penetrates less into the skin. The 10 – 50 kDa fraction is intended for deep penetration, longer chains for surface and long-lasting hydration.

Suitable for products such as

• Moisturising and anti-wrinkle serums – the main application; short chains penetrate deeper and the effect is most pronounced here.
• Tonics, mists and essences – minimal impact on viscosity preserves the fluid consistency, allowing the product to be sprayed with an atomiser.
• Light creams and gel creams – added to cooled emulsion as a moisturising component of leave-on products for face and body.
• Eye creams and serums – for products targeting the delicate skin around the eyes, where fine lines are the focus.
• Hair tonics and leave-on scalp care – hydration of the scalp and hair without weighing them down.

The raw material is intended for leave-on products. It is not suitable for anhydrous products such as oil serums, balms or butters – it requires a water phase.

What is good to know

The solution in water is clear and at standard dosages does not affect the appearance of the product. The raw material is not classified as hazardous, contains no known skin, fragrance or food allergens, and is readily biodegradable. It originates from fermentation, contains no materials of animal origin and has not been tested on animals.
