LIPOSOME AND PERSONAL CARE COMPOSITION COMPRISING THEREOF |
摘要 |
<p>A liposome comprising a phospholipid, a hydrophobic active comprising a carboxylate group, and a component selected from a group consisting of: a hydrophilic adjuvant comprising a positively charged group, a complex of said hydrophobic active with said hydrophilic adjuvant, and combinations thereof. An aqueous liposome dispersion comprising the liposome, and a personal care composition comprising the liposome. A process of preparing the liposome, comprising the steps of: forming a premix by dissolving a phospholipid, a hydrophobic active comprising a carboxylate group in an organic solvent; evaporating off said organic solvent from the premix to form a phospholipid film; and hydrating said lipid film with a hydration medium comprising a hydrophilic adjuvant comprising a positively charged group and homogenize the medium to form an aqueous liposome dispersion.</p> |
