PRUNUS DOMESTICA WOOD ASH.

Avoid CAS 90082-87-4 / ORAL CARE

PRUNUS DOMESTICA WOOD ASH, derived from plum wood, is a mineral-rich powder primarily composed of calcium, magnesium, potassium, and phosphorus. When hydrated, it forms a strongly alkaline solution, typically exhibiting a pH range of 9.0 to 13.5. Historically, its abrasive and highly alkaline nature has been utilized for cleaning purposes.

Summary

Science

Mechanism of Action

This ingredient's primary mechanism is based on its composition of mineral carbonates and oxides. Upon dissolution in water, these components create a strongly alkaline environment, which can significantly influence the pH of a formulation. While specific skincare mechanisms are not detailed, its potent alkalinity means it functions as a strong base, capable of interacting with skin in a manner similar to other caustic agents.

Stability

PRUNUS DOMESTICA WOOD ASH is inherently stable in its highly alkaline state. However, to integrate it into a skin-compatible cosmetic formulation, significant pH adjustment would be required, altering its native chemical environment and potentially its properties.

Conflicts

  • strong acids (due to high alkalinity)
  • treated wood ash (potential for toxic chemicals)

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

Formal safety assessments by regulatory bodies such as CIR, SCCS, or FDA specifically for PRUNUS DOMESTICA WOOD ASH in cosmetic applications are not available. Its inherent strong alkalinity (pH 9.0-13.5) indicates that fresh ash can be caustic, posing a high risk of irritation or damage to the skin. Additionally, the presence of heavy metals, which can vary based on the wood source and burning conditions, is a potential toxicological concern. Dermal toxicity has not been determined.

Our Assessment

Verdict

Avoid

Given its extreme alkalinity, caustic potential, and a complete absence of safety and efficacy data for cosmetic use, PRUNUS DOMESTICA WOOD ASH presents a high risk of skin irritation and damage, rendering it unsuitable for precision skincare formulations.
