Lemongrass Oil

Lemongrass Oil 

Lemongrass Oil is a volatile essential oil obtained from the leaves and stalks of lemongrass plants, most commonly Cymbopogon citratus or Cymbopogon flexuosus. Cosmetic-grade Lemongrass Oil is produced through steam distillation, a physical extraction process that captures the oil’s naturally occurring aromatic compounds without chemical modification. The oil is characterized by a high citral content, which defines its fresh, citrus-like aroma and functional behavior. The production process does not involve ethoxylation, sulfation, or petrochemical modification, supporting its use in clean and traditionally derived cosmetic formulations.

From a formulation standpoint, Lemongrass Oil functions primarily as a fragrance ingredient and sensory modifier. It is typically used at low concentrations due to its strong aromatic profile and active constituents. In cosmetic formulations, it is incorporated into the oil phase or properly solubilized for aqueous systems. Its performance is influenced by concentration, solubilization method, overall fragrance composition, and product format, particularly in leave-on applications.

In finished products, Lemongrass Oil delivers a bright, fresh, citrus-herbal scent often associated with cleansing, energizing, and deodorizing product concepts. At very low levels, it adds freshness and clarity to fragrance blends, while higher levels create a more pronounced aromatic presence. It is commonly used in soaps, body washes, cleansers, shampoos, massage products, deodorizing formulations, and aromatherapy-inspired skincare where a crisp, uplifting sensory profile is desired. Due to its potency, careful formulation and conservative usage are essential.

From a clean standards and safety perspective, Lemongrass Oil has a long history of cosmetic and topical use and is accepted within global cosmetic regulatory frameworks when used within established limits. It is biodegradable and plant-derived, but its high citral content means it may cause irritation or sensitization if overused. Responsible formulation practices, including adherence to fragrance guidelines and appropriate dilution, are critical. Its functional and aromatic profile supports inclusion in ingredient offerings carefully selected by Suncoast PCP for controlled cosmetic formulation use.

Suncoast PCP carefully selects Lemongrass Oil based on aromatic quality, purity, and consistency, ensuring reliable performance in fragrance-forward and cleansing-focused cosmetic applications while aligning with clean and modern formulation standards.

DIY Education and Formulation Guidance

For DIY formulators, Lemongrass Oil should be used with precision due to its strong aroma and citral content. It is typically added during the cool-down phase to reduce volatilization and scent loss. Accurate weighing and conservative dosing are strongly recommended, especially for leave-on products.

In water-based formulations, Lemongrass Oil must be properly solubilized to ensure clarity and stability. Patch testing is recommended when formulating products intended for sensitive skin.

Formulation Compatibility & Common Combinations

Lemongrass Oil is compatible with carrier oils, butters, waxes, surfactants, and fragrance-compatible emulsifier systems. It blends well with essential oils such as lavender, eucalyptus, tea tree, ginger, and citrus oils to create fresh, clean, or spa-inspired aromatic profiles. In emulsions, it is typically incorporated into the oil phase or pre-blended fragrance component.
