Freeze Drying of Cosmetics
In the cosmetics industry, freeze-drying (lyophilization) is critical for stabilizing high-value, labile active ingredients such as vitamin C (ascorbic acid), peptides, probiotics and certain plant extracts etc. that are rapidly degraded in water-based solutions due to oxidation, hydrolysis or microbial growth.
By removing water through sublimation, freeze drying coverts active ingredients into a stable, anhydrous powder and preserves their bioactivity and extends shelf life significantly. This ensures the maximum efficacy and consistent performance of serums, ampoules, and treatment masks, allowing brands to deliver clinically proven results without relying on high concentrations of synthetic preservatives.
Freeze Dried Benefits
Freeze drying is processed under vacuum and water is removed from solid state to vapor state, which means materials always in minus temperature during the drying process. The low temperature drying completely prevents decomposition and oxidation that caused by high temperatures, perfectly preserve the antioxidant potency of vitamins and the bioactivity of peptides.
By using freeze drying technology, dried products final water contain less than 3%, this restrict the activity of microorganism, your products can be dried (preserve) without adding additives or alcohols, safe and meet ‘pure’ label.
Whatever your raw materials are paste, aqueous, granular or loose type, freeze drying technology can dry them, uniformly and completely. Convert them into dry, stable solid form that are easier to handle, transport, and store.
Freeze dried cosmetic or ingredients can be packed individually, split from its reconstitution medium, consumers combine them at the moment of use, enjoying the fun of a personalized, fresh “mix” while guaranteeing a contamination-free application.
People caring and willing to invest more in the body, freeze-dried cosmetics and personal care products are more and more popular. It adds value to your product, your brand and is the trend.
Drying Examples
Freeze drying protects labile components from degradation (e.g. peptides, amino acid, vitamins, plant extracts etc.) which are heat sensitive but necessary for cosmetics and personal care products, guarantee bio-activity, improve product quality and add value to your product. Application and drying examples including but not limited to:
- Essence:
- Concentrated active ingredients (such as polypeptide, cell modulators, vitamins, acids and oxidations etc.) filled and freeze dried in ampoules or vials.
- Masks:
- Freeze drying sheet masks and eye masks, add essence to recovery.
- Powder Sphere:
- Form active ingredients to small particles and freeze dry them, drop into water to reactivate.
- Personal Care Products:
- Freeze dry personal care products (such as mouth wash, shampoo etc.) to effervescent tablets, quick reconstitution by adding water.
