Bisabolol natural
Description
Bisabolol Natural – Soothing, Anti-Irritant, Skin Barrier Protector
Natural Bisabolol (also known as Alpha-Bisabolol) is used in cosmetics due to its skin-soothing properties and its ability to reduce signs of irritation. Its structure allows it to intervene in mitigating surface skin inflammatory responses, serving as a standard raw material in formulations designed for sensitive, reactive, fragile, or stressed skin.
It is an unsaturated monocyclic sesquiterpene alcohol, typically obtained through the distillation and purification of Candeia tree bark (Vanillosmopsis erythropappa) or chamomile flowers.
Ingredients (INCI): Bisabolol.
Technical Characteristics
- Appearance: Oily liquid, colorless to pale yellow, with a delicate, characteristic odor.
- Solubility: Soluble in vegetable oils, melted butters, cosmetic esters, and alcohol.
- Cosmetic function: Soothing agent, anti-irritant, skin protectant.
- Recommended usage dosage: 0.1% - 1.0%
- Stability: Exhibits high thermal stability (withstands temporary heating up to 80°C) and is stable across a wide pH range (3.0 - 11.0).
Main Properties
- Skin Soothing: Contributes to the rapid reduction of tightness, burning sensations, or discomfort in the epidermis.
- Anti-Irritant: Helps reduce transient erythema (redness) induced by UV radiation, chemical substances, or mechanical factors.
- Barrier Function Support: Supports the physiological repair processes of the stratum corneum, improving the appearance of dry, cracked, or flaking skin.
- Penetration Enhancer: Its molecular structure facilitates optimal skin penetration for other active ingredients in the formula.
Applications
- Creams, lotions, and serums for sensitive, reactive, intolerant, or atopic-prone skin.
- Baby care products – diaper cream, body lotions for children.
- After-shave formulations, post-depilatory products, or post-peeling treatments.
- Emulsions, gel-creams, and after-sun soothing balms.
- Lip balms, hand creams, and ointments for rough or cracked areas.
Formulation Guide and Synergies
The lipophilic nature and stability of bisabolol allow for easy integration into various formulas.
- Procedure: In hot-process emulsions (creams), bisabolol can be added either to the oil phase or during the cooling stage. Final-stage addition is frequently used to preserve the integrity of its organoleptic qualities. In pure oil serums, it is mixed directly into the lipid base at room temperature.
- Use in Aqueous Formulations: Because it is not water-soluble, incorporating bisabolol into toners or aqueous solutions requires the use of a solubilizer; otherwise, the active will float on top of the liquid as oily droplets.
- Synergies:
- Soothing Complex: Combines well with Panthenol, Ectoin, and Allantoin, delivering a comprehensive response against dehydration and irritation.
- Reactive Skin: Pairs harmoniously with Mallow Extract, Betaine, and Centella pure powder in anti-irritant serums and creams.
- Addition to Cream Base: Add at a concentration of 0.5% directly into cream bases at room temperature.
Frequently Asked Questions (FAQ)
What is the difference between Natural and Synthetic Bisabolol?
The main difference lies in the isomeric structure and biological efficiency of the product. Natural bisabolol is extracted directly from the plant and contains 100% of the biologically active isomer, known as alpha-bisabolol. The synthetic version (obtained via laboratory chemical reactions) is a racemic mixture of four different isomers, of which only a small fraction is the active form. Consequently, natural bisabolol demonstrates greater efficacy than synthetic bisabolol at the same concentration.
Does it have allergenic potential, given that it comes from plants?
No. Although the plants from which it is extracted may contain compounds such as sesquiterpene lactones, the isolation process of natural bisabolol ensures high purity, eliminating protein fractions and potentially sensitizing compounds. Pure bisabolol is classified as a hypoallergenic ingredient and is specifically used to counteract and reduce the irritating potential of other substances in cosmetic formulations.
Safety in Use and Storage
Safety Profile: Evaluated as safe, non-toxic, non-sensitizing, and non-comedogenic in standard dermatological applications, showing optimal compatibility with all skin types.
Precautions: For external cosmetic use only. Avoid contact with eyes. Keep out of reach of children.
Storage: Store in a closed container, in a dry and cool place.
