Brassicyl Valinate Esylate ●
TL;DR. It is a cationic conditioning agent used mainly in hair care to reduce static, improve wet combing, and add slip in conditioners, masks, and co-washes. It can also help build structure when paired with fatty alcohols.
What does Brassicyl Valinate Esylate do in a cosmetic formula?
It is a cationic conditioning agent used mainly in hair care to reduce static, improve wet combing, and add slip in conditioners, masks, and co-washes. It can also help build structure when paired with fatty alcohols.
Is Brassicyl Valinate Esylate clean?
From a clean beauty perspective, it is generally viewed favorably because it provides conditioning without conventional quaternary ammonium salts and is not a common restricted-list flag. Like many cationic surfactants, it can be irritating to eyes or skin at higher concentrations, so use level and rinse-off context matter.
Is Brassicyl Valinate Esylate sustainable?
This material is largely plant-derived from renewable oilseed fatty alcohols plus amino-acid-based chemistry, and it is reported to be readily biodegradable. Its footprint depends on agricultural sourcing and manufacturing energy, but it is not associated with silicone-like persistence or microplastic concerns.
Is Brassicyl Valinate Esylate COSMOS-approved?
It is permitted under COSMOS-natural and can be used in COSMOS-organic formulas subject to the finished-product organic-content rules. Its renewable feedstock profile and biodegradability fit Green Chemistry principles better than many traditional conditioning cationics.
How does Brassicyl Valinate Esylate work chemically?
The molecule is a long-chain cationic amino-lipid salt, with a hydrophobic alkyl segment and a positively charged head group that adsorbs to negatively charged hair keratin. Typical use is about 0.5–3% active in rinse-off conditioners and masks, often around pH 3.5–5.5, and it pairs well with fatty alcohols to form lamellar conditioning systems.
