US 2025/0049692 A1 · ANTIPERSPIRANT COMPOSITION

Abstract

The present invention relates to antiperspirant composition, particularly to antiperspirant composition having high levels of oil. The present inventors have found that when compositions having an unsaturated oil such as sunflower seed oil is present in the antiperspirant composition together with high total oil content present in the composition, the fabric which comes in contact with the composition in the axilla tends to get stained on repeated use. The present inventors have found that the problem of staining or yellowing of fabrics is significantly lowered when a combination of an alkoxylated aliphatic ether with an alkyl chain length of C3 to C10 and specific polyethylene glycol diester of fatty acid with chain length of C12 to C18 is used in an antiperspirant composition having high total oil content including unsaturated oil and an antiperspirant active.

An antiperspirant composition comprising:

i. an alkoxylated aliphatic ether having the general formulae (IA) or (IB)
R—O—(C2H4O)n—H (IA)
or R—O—(C3H6O)n—H (IB);
wherein the C3H6 in formula (IB) is linear or branched;
where n is an integer from 10 to 18;
and,
where R is a straight or a branched linear alkyl group having from 3 to 10 carbon atoms;
ii. a polyalkylene glycol diester of the general formulae (IIA) or (IIB)
R2CO·O—(C2H4O)n—CO·R1 (IIA)
or
R2CO·O—(C3H6O)n—CO·R1 (IIB);
wherein the C3H6 in formula (IIB) is linear or branched;
and where n is an integer from 8 to 150;
and R2 and R1 are each independently selected from C12 to C18 alkyl group or an aryl group.
iii. 0.1 wt. % to 5 wt. % unsaturated oil;
iv. a metal based antiperspirant active;
wherein total oil content including the unsaturated oil present in the composition ranges from 55 wt. % to 65 wt. %
and further wherein the polyalkylene glycol diester to alkoxylated aliphatic ether in the composition is present in a weight ratio of 0.05 to 2.
