Citrustem Orange Callus Culture Active for Advanced Anti-Age Skin Care

Citrustem is a ready-to-use water and glycerin based cosmetic active built around Citrus Aurantium Dulcis callus culture extract. It is intended for serums, emulsions, masks, and concentrated treatments developed for mature-looking skin, uneven texture, and reduced visual firmness. Within the Mylo Opt catalog, the ingredient belongs to the Anti-Age Actives category.

The declared INCI is Water, Glycerin, Citrus Aurantium Dulcis (Orange) Callus Culture Extract, Xanthan Gum. Water and glycerin provide a formulation-friendly carrier, orange callus culture extract serves as the principal botanical component, and xanthan gum supports uniform dispersion. The developer presents Citrustem as an orange cell culture active designed for products that promote a smoother, denser, and younger-looking skin appearance.

Botanical cell culture in modern cosmetics

Plant callus cultures are produced by growing selected plant cells under controlled conditions. This approach gives cosmetic formulators access to standardized botanical materials without relying solely on conventional harvesting of fruit, leaves, or roots.

Citrustem should not be confused with orange essential oil, orange peel fragrance, or a conventional fruit extract. Its role in a formulation is functional rather than aromatic. It is therefore suitable for fragrance-free concepts and products where an intense citrus scent would be undesirable.

The active is most relevant to premium facial care, professional treatments, and products developed for skin that appears less firm, dry, or uneven. It can support a modern anti-age concept based on botanical biotechnology, hydration, and barrier-focused formulation.

Facial care applications

Citrustem can be incorporated into facial serums, cream gels, day and night emulsions, eye-area products, masks, and neck care. Its pre-dispersed liquid format simplifies addition to water-based systems and makes it useful for laboratory development and contract manufacturing.

In lightweight serums, it can be combined with sodium hyaluronate, betaine, panthenol, niacinamide, and amino acid blends. In richer emulsions, complementary ingredients may include ceramides, squalane, phytosterols, peptides, tocopherol, and emollient oils.

For eye-area formulations, the complete product must be designed for that application, including conservative active levels, appropriate preservation, controlled viscosity, and compatibility testing.

Citrustem may also be used in treatment makeup, tinted moisturizers, and hybrid skin care formulas where a smooth application profile and a botanical anti-age positioning are required.

Professional products and masks

The ingredient is suitable for ampoules, salon masks, concentrated gels, and finishing creams used in professional cosmetic routines. It can be paired with hydrocolloids, alginates, hyaluronic acid systems, and gentle botanical extracts.

Because the active already contains xanthan gum, formulators should consider its contribution to viscosity. In delicate serum systems, the total amount of xanthan, carbomer, cellulose gum, or other rheology modifiers may need adjustment.

For private label and scale-up projects, pilot stability testing should cover viscosity, appearance, odor, preservation, packaging compatibility, and performance at different storage temperatures.

Formulation and processing

Citrustem is added to the aqueous phase or incorporated during the cool-down stage of an emulsion. Processing below 40°C is preferred to avoid unnecessary heat exposure of the botanical extract.

A practical use range is approximately 0.5-5%, subject to the supplier documentation for the exact grade and batch. Lower levels are appropriate for supporting formulas, while more concentrated concepts require careful stability and compatibility assessment.

The active can be blended with water-soluble moisturizers, peptides, vitamins, and botanical extracts. It should be incorporated with moderate agitation to achieve uniform distribution without excessive aeration.

Its water and glycerin content must be included in the overall phase calculation. The xanthan gum contribution should also be considered when developing clear gels or low-viscosity serums.

Store Citrustem in its tightly closed original container, protected from direct light and excessive heat. Follow the batch certificate for storage temperature, shelf life, and handling requirements.

Citrustem peptide hydration concentrate

Purified Water 74 ml

Rose Hydrosol 8 ml

Citrustem 4 ml

Glycerin 3 ml

Betaine 3 g

Panthenol 2 ml

Peptide Complex 2 ml

Sodium Hyaluronate Gel 2 ml

Hydroxyethylcellulose 0.4 g

Preservative 1 ml

Disperse hydroxyethylcellulose in glycerin, then add the mixture gradually to purified water while stirring until fully hydrated. Dissolve betaine and panthenol in the water phase and add the rose hydrosol. Once the batch is uniform and below 35°C, incorporate Citrustem, the peptide complex, sodium hyaluronate gel, and preservative. Mix slowly to minimize air incorporation, then verify pH, viscosity, and preservation before filling.
