- SonneNatural Q&A: SonneNatural Fluidity 40P
The world is changing and your customers are changing too. Your products need to continue to meet stringent regulatory requirements, exceed customer expectations and align with broader trends toward sustainable solutions*.
SonneNatural™ Fluidity 40P is a next-generation 100% bio-based renewable white alkane (C15–C19) that meets the growing need for high-performance alternatives to traditional silicones and mineral oils in personal care formulations. Designed to deliver both functionality and formulation flexibility, it offers excellent purity, stability, and compatibility with sensitive actives, fragrances, and colorants, making it a versatile solution across hair care, skin care, and fragrance applications.
This Q&A explores how SonneNatural™ Fluidity 40P helps formulators address these evolving industry needs—from achieving a premium sensory experience and proven performance benefits.
SonneNatural™ Fluidity 40P is a 100% bio-based, readily biodegradable Renewable White Alkane (INCI: C15–C19) produced using patented technology. It provides an excellent alternative to cyclic siloxanes (D4, D5, D6), low-viscosity white mineral oils, and vegetable oils, while preserving purity, stability, and sensory performance.
SonneNatural™ Fluidity 40P is part of the expanded SonneNatural™ portfolio, reflecting Sonneborn’s commitment to sustainability, providing innovative products based on naturally derived ingredients. The portfolio includes three product lines offering Renewable White Alkanes, advanced plant-based petrolatum and wax alternatives, and customizable hybrid solutions.
The product meets USP, NF, Ph. Eur., BP, and JP purity requirements. It is clear, bright, odorless, and non-fluorescent under UV light, indicating extremely low aromatic impurity levels.
SonneNatural™ Fluidity 40P is chemically inert and highly compatible with sensitive actives, fragrances, and colorants. It is stable over time and supported by UV and elevated-temperature stability testing, maintaining performance across diverse environments. The product also demonstrates an expected shelf life up to three years.
In hair care applications, it delivers up to 55% frizz reduction after 24 hours in high humidity and a 44% increase in shine versus cleansed, untreated hair. It provides a silky, low-friction sensory profile with a clean, non-greasy afterfeel and outperforms low-viscosity silicones in cleansing systems.
Yes. Clinical testing confirms no skin irritation potential (HRIPT semi-occlusive patch, 112 subjects aged 20–70), non-comedogenic and non-pore clogging (comedogenicity testing, 20 subjects aged 18–40), and non-eye irritating (tested via EpiOcular™ Eye Irritation Test, OECD 492).
It contains 100% bio-based carbon content verified by ASTM D6866, with a Natural Origin Index (NOI) of 1 per ISO 16128. The product is readily biodegradable per OECD 301B.
SonneNatural™ Fluidity 40P offers up to a 68%* reduction in Product Carbon Footprint (Cradle-to-Gate) versus siloxanes and up to a 60%* reduction (Cradle-to-Grave) versus white mineral oils.
SonneNatural™ Fluidity 40P meets the following certifications and compliance standards, supporting global market access and diverse brand positioning strategies.
- REACH registered
- It is GMO-free (via PCR testing)
- Kosher, Halal and Vegam certified
- Leaping Bunny compliant
- Complies with California Proposition 65
- Meets BDF02 PAH specifications, including 32 PAH Grimmer Analysis
- No acute toxicity (ELt50-72hr> 0.11/1000 as tested via OECD 201)
It is designed for personal care applications including hair care, skin care, fragrances, and formulations incorporating sensitive actives, fragrances, colorants, or seeking silicone alternatives and renewable content.
