1. Health Risks of D5
Scientific evidence has confirmed that D5 (Decamethylcyclopentasiloxane) can penetrate the skin and accumulate in the human body, posing serious health risks:
• Deep skin penetration: D5 can pass beyond the epidermis and dermis, reach mucous layers, enter the circulatory system, and accumulate in fat tissues.
• Endocrine disruption: D5 may cause hormonal imbalances and disrupt the endocrine system.
• Long-term accumulation: D5 is persistent in the body and may lead to chronic health concerns.
2. Environmental Impact of D5
D5’s negative effects go beyond human health and include serious environmental consequences:
Persistence in air, water, and soil: Volatile methylsiloxanes (cVMS), including D5, spread through the environment and can persist for hundreds of years.
Ecosystem pollution: D5 bioaccumulates in living organisms, threatening ecosystems.
Contamination of food and air: Humans may be indirectly affected by air, water, and food contaminated with cVMS.
3. The Global Shift Toward Eliminating D5
In response to the clear risks posed by D5, regulators and major cosmetic brands have taken action to remove it from cosmetic products:
• Europe: Legally limits D5 to 0.1% in both leave-on and rinse-off products.
• United States: While there is no official ban, products containing D5 must carry hazard warnings.
Leading brands embracing the “D5-free” movement:
• Unilever: Began phasing out D5 from hair care products in 2015 and is expanding this initiative to skincare.
• P&G: Has fully removed D5 from formulas in sensitive markets, especially in Europe.
• Olaplex: Successfully eliminated D5 from their formulations, despite it being a major component in earlier products.
• L’Oréal & Estée Lauder: Currently progressing in their D5 replacement roadmaps.
4. “D5-Free” Cosmetic Brands
Many cosmetic brands have completely eliminated D5 from their formulas:
• Hair care: Olaplex, Briogeo, Innersense, Living Proof
• Skincare: Paula’s Choice, Youth to the People, Tata Harper, Drunk Elephant
• Makeup: RMS Beauty, Kosas, Ilia
5. D5 Alternative Solution: XJY 058
A suitable alternative to D5 must meet the following criteria:
• Safe and non-toxic to human health and the environment
• Similar volatility and spreadability to D5
• Lightweight and non-greasy sensory feel
XJY 058 meets these key requirements and is considered a promising solution. Its highlights include:
• Solves D5’s drawbacks: D5 evaporates too quickly and leaves no sensory residue.
• Balanced performance: When blended with DM10 (a low molecular weight, volatile Dimethicone) at a 50/50 or 40/60 ratio, XJY 058 delivers optimal spreadability and feel on the skin.
Conclusion
D5 is being increasingly restricted worldwide due to its negative impact on health and the environment. The “D5-free” trend is rapidly becoming an industry standard, driven by regulatory actions and brand commitments. XJY 058 offers a viable alternative that maintains product performance while ensuring safety for consumers and sustainability for the planet.
