RHUS SUCCEDANEA FRUIT WAX.

Valuable CAS 8001-39-6 / BINDING, VISCOSITY CONTROLLING

Rhus Succedanea Fruit Wax, commonly known as Japan Wax, is a natural, plant-derived wax celebrated for its emollient and film-forming properties. It actively softens and moisturizes the skin by creating a protective barrier, which effectively minimizes moisture loss and enhances overall skin condition.

Summary

Emollient Film-forming Skin-conditioning Humectant Binding agent Thickener Viscosity controlling Stabilizer

Science

Mechanism of Action

This botanical wax functions primarily as an emollient, establishing a protective film on the skin's surface. This physical barrier significantly reduces transepidermal water loss and provides a defense against environmental stressors. In addition to its moisturizing capabilities, it acts as a skin-conditioning agent and exhibits mild humectant properties. Within formulations, it serves as a binding agent, thickener, and stabilizer, contributing to improved product texture and application characteristics.

Key findings

  1. 01 Multiple human skin irritation and sensitization studies, including a modified Draize-Shelanski-Jordan test, found that Rhus Succedanea Fruit Wax at concentrations of 2.5%, 36%, and 50% in petrolatum caused no irritation or allergic reactions in tested subjects.

Dusting Analysis

Not commonly dusted

As a wax, Rhus Succedanea Fruit Wax is intrinsically formulated to melt or integrate into a product matrix, making 'dusting' – a phenomenon typically associated with dry, powdered, or unstable active ingredients – an irrelevant concern for this ingredient.

Stability

The wax demonstrates a relatively high melting point, ranging from 48°C to 54°C, which contributes to increased formulation stability and is ideal for products requiring a thicker consistency. It maintains chemical stability under typical conditions of use and storage.

Safety

Safety Profile

CIR Status

Max tested
37.9%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Rhus Succedanea Fruit Wax is safe for use in cosmetics, with the highest reported concentration in 2022 being 37.9% in eyebrow pencils. While generally considered safe and non-irritating, individuals with existing allergies or highly acne-prone skin might experience mild sensitivity or potential comedogenic effects, particularly when used in higher concentrations. A very minor risk of reaction exists for highly sensitive individuals due to its botanical origin from the Toxicodendron species, which is known to contain the allergen urushiol.
