Table of changes Change No. Date Scope Amdt 1 1998 Amended to substitute an automated method of determining the drop points of petroleum jelly (petrolatum) for the existing manual method, and to correct an editorial error. Amdt 2 1999 Amended to change the drop melting point range in order to align with international specifications. Amdt 3 2008 Amended to change the designation of SABS standards to SANS standards, to update referenced standards and to update the definition of "acceptable". Amdt 4 2016 Amended to remove reference to the certification mark, and to update definitions.

Petroleum jelly (petrolatum) 1 Scope This standard specifies requirements for refined petroleum jelly (petrolatum) in two colour grades (white and yellow), which is intended for use in pharmaceutical and cosmetic applications. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this standard. All standards are subject to revision and, since any reference to a standard is deemed to be a reference to the latest edition of that standard, parties to agreements based on this standard are encouraged to take steps to ensure the use of the most recent editions of the standards indicated below.
