Abstract
A composition of matter comprises a lanolin free absorption base. The absorption base in includes a superior lanolin free emulsifier selected for its HLB (hydrophilic-lipophilic balance) compatibility, neutral, nonionic absorption base ideal for the incorporation of many active ingredients. Use of this emulsifier permits low production temperatures during base manufacture, thereby allowing incorporation of heat labile active ingredients. More efficient emulsification is realized, which leads to a much lower concentration of emulsifier. The absorption base is especially effective formulation for hydrocortisone or its salts due to HLB compatibility, and stabilizing ingredients often found in prior art products can be eliminated due to HLB compatibility.
Claims5
A method of making an emulsified absorption base comprising:
- a) heating white petrolatum up to 80° C.;
- and
- b) adding an effective amount of methyl glucose dioleate to the white petrolatum and mixing the two components together to form an absorption base;
- and
- c) diluting the absorption base with water preheated to up to 50° C. to form the emulsified absorption base for skin use alone or skin use when the emulsified absorption base is combined with other ingredients.
