Skin dryness and irritation are common dermatological concerns often treated with emollient creams that hydrate and soothe the skin. With increasing interest in herbal formulations, Calendula officinalis (commonly known as marigold) has gained attention for its anti-inflammatory, antimicrobial, and skin-healing properties. This study aimed to formulate and evaluate an emollient cream incorporating marigold extract to determine its effectiveness and suitability for topical application.

Marigold flowers were collected, shade-dried, and subjected to ethanolic extraction using the maceration method. The extract was then incorporated into a cream base formulated using standard emulsifying agents, humectants, and stabilizers. Three different formulations (F1, F2, F3) with varying concentrations of marigold extract were prepared and evaluated.

Physicochemical parameters including pH, viscosity, spreadability, stability (under accelerated conditions), and organoleptic properties were assessed. Microbial load testing and in vitro skin irritation studies using egg membrane and patch testing on human volunteers were also conducted. Additionally, the moisturizing efficacy was evaluated using a corneometer over a 4-week period.

The results indicated that all formulations were stable and met acceptable cosmetic standards. Among them, F2 (with a moderate concentration of extract) showed the best balance of spreadability, skin absorption, and moisturizing effect without causing irritation. The cream exhibited good antimicrobial properties and helped improve skin hydration significantly compared to the base cream.
