摘要:
A dispersion contains particles of metal oxide dispersed in a siloxane fluid and a dispersing agent which is a polysiloxane wherein (i) the polysiloxane contains in the range from 0.1 to 3 carboxyl groups, and (ii) the ratio of non-carboxyl group containing monomer units to carboxyl group containing monomer units in the polysiloxane is in the range from 40 to 150:1. The dispersion is particularly suitable for use as an ingredient in sunscreening cosmetics.
摘要:
Adjuvant surfactant compositions for beneficially modifying the properties, particularly rheological properties, of surfactant systems are provided. The surfactant compositions, which include at least one primary surfactant and can be substantially free of monoethanolamines, diethanolamines, and diethanolamides include alkoxylated hydroxyalkyl isostearamide which is substantially a liquid at room temperature. The isostearamide composition may also include a second surfactant. Methods of preparation and uses are also disclosed.
摘要:
A visually clear and substantially colorless antimicrobial-containing solution comprising at least 20 weight percent of an alkoxylated monoalkanolamide surfactant represented by formula II: (II)wherein:R1 represents a hydrocarbon radical;R2 represents a hydrogen atom, -CH3 or -CH2-CH3 radical; andx independently represents at least 1. The antimicrobial-containing solutions are suitable for readily mixing into cosmetics and disinfectant cleaning products.
