- Introduction
More recently, Hydrocolloids have found a fit in the personal care industry, where they often replace synthetic chemicals with similar properties. Driven by consumers’ thirst for “all-natural” products, many manufacturers are trying to leverage the long history of hydrocolloids in the food industry for personal care applications.
- Specific Applications
Hydrocolloids already appear in the ingredients lists of many:
- Lotions,
- Creams,
- Haircare products,
- Shower gels,
- Sunscreens,
- Toothpaste,
- Antiperspirants/deodorants,
- Hand sanitizer,
- Body lotion,
- Seaweed gel mask.
- Natural Hydrocolloids in Personal Care products
P&G launched the Pantene® Nature Fusion hair care collection. Key to the line’s marketing approach is that Nature Fusion products contain a chemically modified version of cassia gum, a hydrocolloid from the seeds of a legume native to India. Pantene scientists found that adding hydroxypropyltrimonium cations to the cassia polysaccharide enhanced its hair-conditioning properties.
