Allantoin

Allantoin powder is a versatile ingredient widely used in skin and hair care formulations due to its numerous beneficial properties. It is a white, odorless, crystalline powder that is derived naturally from the comfrey plant or produced synthetically.
Benefits of Allantoin for Skin:
* Moisturizing: Allantoin is a humectant, meaning it attracts and retains moisture in the skin’s upper layers, preventing dryness and improving hydration. It also has hygroscopic properties, absorbing moisture from the air.
* Skin Soothing and Anti-Irritant: It calms and soothes irritated skin, reducing redness and discomfort caused by various factors. This makes it suitable for sensitive skin and conditions like eczema.
* Skin Protecting: Allantoin enhances the skin’s barrier function, protecting it from external irritants and environmental stressors.
* Promotes Wound Healing: It stimulates cell proliferation and tissue regeneration, aiding in the healing of minor cuts, scrapes, and burns.
* Mild Exfoliating (Keratolytic): Allantoin helps to gently exfoliate the skin by breaking down the intercellular matrix that holds dead skin cells together, leading to smoother and softer skin.
* Anti-Aging: By promoting hydration and cell turnover, allantoin can contribute to a more youthful appearance and reduce the appearance of fine lines and wrinkles.
* Improves Skin Texture: It enhances skin smoothness and can help minimize the appearance of pores.
Benefits of Allantoin for Hair and Scalp:
* Moisturizing: It helps to hydrate the scalp and hair, preventing dryness and frizz.
* Soothes Scalp Irritation: Allantoin can alleviate itching and irritation of the scalp.
* Promotes Healthy Scalp: Its anti-irritant properties contribute to a healthier scalp environment.
* May Improve Hair Luster and Softness: By conditioning the hair, it can enhance shine and make it feel softer.
Usage Rate:
The typical usage rate of allantoin powder in cosmetic formulations ranges from 0.1% to 2.0%.
* For general skincare and haircare products (lotions, creams, shampoos, conditioners): The recommended concentration is usually between 0.1% and 0.5% to achieve its moisturizing, soothing, and skin/scalp conditioning benefits.
:
* Solubility: Allantoin is water-soluble, but its solubility in water is limited (around 0.5% at room temperature). For concentrations above this, it may be necessary to use a thickener or add it during the cooling phase of an emulsion with good agitation to ensure proper dispersion and prevent recrystallization.
* pH Stability: Allantoin is stable in a pH range of 3 to 8.
* Heat Sensitivity: It is generally recommended to add allantoin during the cool-down phase of formulation (below 50°C/122°F) to avoid potential recrystallization into larger particles.
* Compatibility: Allantoin is generally compatible with most cosmetic ingredients.
