Some natural fibers like silk, wool, and cashmere can safely be laundered in your washing machine without the need for dry cleaning. Although these are different fabrics, they are all protein-based and should not be washed with regular detergent; even gentle enzyme detergents should be avoided for washing wool and silk, as detergent enzymes work by breaking down protein and can damage silk and wool fiber over time.
That’s why we offer Heritage Park Silk and Wool: to effectively clean protein-based fabrics while protecting them from damage. This concentrated liquid detergent is a pH-neutral, plant-based formula gently cleans and removes stains from clothes and home textiles while preserving the softness and integrity of silk, wool, cashmere, feathers, and other delicate fabric. Use it to wash natural fiber apparel and home textiles in your machine (regular and HE machines) or to hand wash. Can be used in any temperature or setting (always follow the manufacturer’s care guidelines).

We've found that it can be difficult to find the best laundry detergent for machine and hand washing your silk, woolens, and other delicate items. This is why Mulberry Park Silks partnered with Heritage Park to assist in the development of their concentrated gentle liquid detergent formula.
They use only a short list of natural, silk-safe ingredients and make their detergent in small batches for the ultimate quality control. A concentrated laundry soap formula means less water (most commercial detergents are primarily water) and less plastic packaging (smaller bottles). You can also reuse your bottle with their eco-friendly refill packs. Unlike pre-measured laundry pods or messy powder detergent, the easy-to-use measuring cap gives you total control over the amount of detergent you use. It’s total cleaning power with zero waste!

Regular laundry detergent is packed with chemicals, compounds, and dangerous ingredients that can trigger allergies, provoke reactions, and irritate delicate skin. Heritage Park non toxic laundry detergents don't contain any of these problematic ingredients or harmful chemicals:

No Dyes: The dyes used to color a detergent or cleaning product serve absolutely NO purpose and are a source of skin irritation and allergies.

No Sulfates: These chemical compounds are used to create foam in laundry products (and household cleaning and personal care products like dish soap, body wash, and shampoo). Sulfates irritate allergies, eczema, and other skin conditions.

No Phosphates: Used to soften hard water, phosphates are toxic chemicals dangerous for people and the environment. Most reputable detergent manufacturers have stopped using phosphates.

No Chlorine: This highly reactive chemical element is used to disinfect and sanitize but triggers irritation and contact dermatitis. It can also cause fading and damage to fabrics over time.

No Bleach: Oxygen and chlorine bleach can irritate the skin. Bleach should be used only following the manufacturer’s directions and in small quantities, never as an ingredient in detergent.

No Optical Brighteners: These synthetic chemicals remain on clothing and laundry to absorb UV light and make items appear brighter. Along with irritating skin, these compounds are NOT biodegradable.
