“…While non-ionic surfactants provide advantages with respect to an enhanced assembly stability, e.g. towards pH-changes or electrolytes, 15 this insensitivity restricts the application of certain formulation methods, which utilize medium induced phase changes, like the pH-mediated transition of fatty acid micelles into liposomes. 16 Unfortunately, carbohydrate surfactants involving ionic charges have not been investigated extensively.…”

“…Polyalkylene oxide block copolymers (BLKs) and alkyl phenol ethoxylates (APEs) are synthetic surfactants frequently used in professional horticultural substrates (Templeton, 1999;Yelanich and Vetanovetz, 2004). The UK restricts the use of APEs and Switzerland has banned them (Hepworth, 2006). Incomplete bacterial biodegradation of APEs has been documented (White, 1993).…”

“…Wide usage of APEs in the United States has resulted in detrimental accumulation in the Cuyahoga River of Ohio (Rice et al, 2003). BLK surfactants are widely used in many industries, but products are limited in abilities because often there is a tradeoff between desired foaming characteristic, biodegradability, and toxicity (Hepworth, 2006). Organic or naturally occurring surfactants generally are not accepted by professional horticulturists because of lack of efficacy data and because they potentially serve as a nutrient source for microbes (Czarnota and Thomas, 2006).…”

“…Organic or naturally occurring surfactants generally are not accepted by professional horticulturists because of lack of efficacy data and because they potentially serve as a nutrient source for microbes (Czarnota and Thomas, 2006). Alkyl polyglucosides (APGs) are synthetic surfactants derived from glucose and palm or coconut oil-based alcohols (Hepworth, 2006) and are considered less harmful to the environment than other surfactants with some current applications as agronomic adjuvants (Czarnota and Thomas, 2006).…”

Alkyl phenol ethoxylate (APE) surfactants are used in horticultural substrates but are considered nonbiodegradable, whereas others such as alkyl polyglucoside (APG) are derived from biodegradable sugar compounds. APE reduced total porosity (TP), container capacity (CC), and aeration porosity (AP) whereas APG with polyalkylene oxide block copolymer surfactant (APG/BLK) increased TP, CC, and AP for some substrates but other substrates remained unaffected by either surfactant. We determined substrate leaching fraction (LF) and wettability rating (WR) after drenches of 0.003 to 0.2 mL·L−1 APG/BLK for six bark substrates for three wetting cycles. After the third wetting cycle, five substrates had reduced LF and increased WR. Drenches of 0.2 mL·L−1 APE or APG/BLK for three wetting cycles indicated that APE was more efficacious than APG/BLK for reducing LF or increasing WR. APE was determined to be an effective surfactant for difficult-to-wet substrates, but drenching sometimes reduced TP. No reductions in TP were noted when using APG/BLK. Drenching rates of 0.003–0.2 mL·L−1 APG/BLK for three successive wetting cycles reduced LF and increased WR for most substrates, indicating potential usage for some horticultural applications.

“…Os tensoativos não-iônicos não apresentam carga positiva ou negativa na parte hidrófila. Existem diversos tipos de tensoativos não-iônicos, entre eles: os alquilfenóis, ésteres de açúcar, alcanolamidas, óxidos de aminas, ácidos graxos, aminas graxas, polióis, derivados de óxido de etileno e/ou óxido de propileno (Hepworth, 2006). Caracterizam-se por proporcionar estabilidade às micelas (agrupações de tensoativos), aumentando a suavidade do sabonete com a pele.…”
